Twitter WhatsApp Billy Lee names strong Limerick side to take on Wicklow in crucial Division 3 clash TAGSlimerickSow and Grow Advertisement Limerick Artist ‘Willzee’ releases new Music Video – “A Dream of Peace” LIMERICK schools can now apply for free ‘Sow and Grow’ packs to help enable school children across the county to learn how to grow their own food this Spring.Schools can log on to https://innocentsowandgrow.com/ and register for a free Sow & Grow pack to be delivered to their school.Sign up for the weekly Limerick Post newsletter Sign Up This year the pupils will learn how to grow cress, baby carrots and runner beans.Each Sow and Grow pack includes a detailed ‘how to grow’ guide focusing on learning in the classroom, soil, growing pots, seeds and expert food growing kits devised by GIY and innocent drinks along with details on how to cook and eat the food grown.Launching the programme, founder of GIY Michael Kelly revealed statistics from a household survey carried out by Behaviour and Attitudes Ireland, that 99 per cent of parents believe that children should know how to grow food.Michael said, “the level of engagement that we get from schools and children for this project each year is incredible. We know just how important it is for kids to learn about growing food from an early age and furthermore that 49 per cent of those surveyed have grown some food at home.However, the survey also found that there is still a lot of work to be done as 29 per cent of children do not eat enough fruit and veg and 14 per cent did not know where their food came from.Previously, the initiative has enabled 100,000 Irish primary school children learn how to grow vegetables in the classroom. and get a deeper connection with food.Registered schools can share their journey through social media and win prizes.

A 22-year-old British man has been found dead at Val-Thorens ski resort after a night out drinking. NUCO Travel Ltd has confirmed that the student concerned was involved in the Oxford-Cambridge Varsity ski trip, which it helped to organise. A spokesman said, “Sadly one of our passengers passed away on Sunday 4th December 2016. At this time, to respect their family’s and friend’s privacy, we will not be commenting further.”According to Swiss newspaper Le Matin, which cited police reports, the man was discovered unconscious in his room by friends early in the morning. Emergency services were called, but the firefighters that arrived at the scene were unable to revive the young tourist, who had died from cardiorespiratory arrest. According to police reports the man and his friends arrived by coach yesterday afternoon before immediately attending a party. It is believed that he died at some point between Saturday night and Sunday morning. Val-Thorens is currently hosting the Oxford-Cambridge Varsity ski trip, the largest student snow sports event in the world. Thousands of students from both universities are currently at the resort, with about 15 per cent of Oxford students attending. The annual event was first held in 1922, and has previously been criticised by Oxford college deans for its reputed debauchery. Students left by coach for Val-Thorens on Friday and arrived yesterday. The trip ends next Saturday. Val-Thorens resort and the Varsity Committee have been contacted for comment.

The fuel will be regularly delivered from the LNG production facilities of the Gazprom Group.The company said that in total 600 tons of liquefied natural gas are planned to be delivered under the contract.Currently, three natural gas units are in operation at the Egorshino-Serov-Sortirovochnoe section of the Sverdlovsk Railway.Mikhail Likhachev, Gazprom Gazomotornoye Toplivo’s general director said that the natural gas fueling infrastructure for the Sverdlovsk Railway system is being developed under a cooperation agreement with Russian Railways with an aim to increase the use of LNG as fuel for rail transport.He added that LNG fueling stations should be set up on the non-electrified sections of the railway.
Scoop Jardine smiled as he put an eventual 48-point dismantling — the largest margin of victory in the 32-year history of the Big East conference — into painful perspective.With SU up by 31 points against a DePaul team with only 30 of its own, Jardine chuckled as he backpedaled to the free-throw line for an and-one opportunity. Following a made fast-break layup during which Jardine was fouled by Blue Demon junior guard Jeremiah Kelly, a three-word dig provided all the perspective Kelly and the Blue Demons needed.‘Come on,’ Jardine said to a dejected Kelly. ‘Please.’Jardine’s smile never seemed to dissipate on a night when his longtime teammate and friend, Rick Jackson, departed the Carrier Dome for good on Senior Day. Jackson tied Jardine for the team-high in points on the night with 14.There was no reason for the smile to fade. Plain and simple: Syracuse embarrassed DePaul 107-59 in a laugher that only amplified in ridiculousness as the game went on. Each of the 10 players who entered in the first half for Syracuse dominated his counterpart in a complete team annihilation. And if the smiles on Jardine and the usually stoic Jim Boeheim didn’t speak to the obliteration, the gravity of the stats did.AdvertisementThis is placeholder textNo. 12 SU (25-6, 12-6 Big East) ended the game shooting a ludicrous 71 percent from the field and 78 percent from 3-point range. In the regular-season finale win in front of 28,086 in the Dome, Syracuse scored 57 first-half points — the most the team has scored in the first half since Dec. 5, 2009, against Maine. In the first half, all 10 of SU’s players scored. DePaul tallied only seven defensive rebounds in the game.No contest. TKO. The game was over right as it started, as SU rolled from the tip. Postgame, DePaul first-year head coach Oliver Purnell couldn’t muster much.‘Once they got on a roll,’ Purnell said, ‘that was it.’The win secured Syracuse a No. 4 seed and a double-bye in next week’s Big East tournament at Madison Square Garden, which starts Tuesday. The Orange will open up play at 2 p.m. on Thursday against the winner of a second-round game between fifth-seeded St. John’s and the winner of Seton Hall vs. Rutgers.But Saturday afternoon, the Orange romped in the moment. With reckless abandon, SU starting guards Jardine and Brandon Triche torched an aloof DePaul defense with easy dribble-drives. The scouting report assembled by Gerry McNamara, SU’s graduate assistant, worked as the defensive Achilles heel of DePaul ruptured. Through a week of watching film, it became apparent to McNamara that the Blue Demons couldn’t defend if not planted in front of SU’s guards, applying Purnell’s brand of ball pressure out of a solid foundation.All game, the Orange screened DePaul until it was completely lost. Attacks from the likes of Jardine, Triche and Kris Joseph to the basket weren’t challenged. The undersized Blue Demons seemed as if they weren’t even there.The result of that scouting report was a scoring exhibition and the most lopsided win in conference history.‘We knew that they wouldn’t hedge as good (defensively on screens),’ Triche said. ‘They were going to put pressure. We knew they weren’t as good helping. We were going to put pressure by penetrating.’Offensively, the guards did whatever they wanted to whoever they wanted. So did everyone else, as maligned freshman center Fab Melo even lit up the tiny Blue Demons for a season-high 10 points on 100 percent shooting. Reserve wings Mookie Jones and James Southerland added nine and seven points, respectively.Former walk-on Brandon Reese scored four of his own. All 17 players on SU’s roster saw time, and against DePaul’s regulars in the final five minutes of the game, SU’s walk-ons even played DePaul close. DePaul only outscored an SU lineup sprinkled with SU’s 13th, 14th, 15th, 16th and 17th players, 7-4.When SU walk-ons Matt Lyde-Cajuste, Nick Resavy, Griffin Hoffmann, Nolan Hart and Russ DeRemer entered the game periodically over the course of the final three minutes, the game was a game for only that final stretch. The other 37 minutes, the embarrassment for DePaul — in what may have been Syracuse’s best game of the year — was ultimate.And the one thing Purnell longed for postgame wasn’t there all day. Any element of stopping SU was a pipe dream in the worst statistical nightmare in Big East history.Said Purnell: ‘We could’ve given them some more resistance.’[email protected] Comments Facebook Twitter Google+ Published on March 4, 2011 at 12:00 pm
Sophomore Kyle Pham made his idea of a subscription-based service that allows people to enjoy 3D printing through a monthly delivery a reality. The only catch — the contents of the shipments are a mystery.On Sept. 15th, Pham officially launched a Kickstarter campaign for his start-up, CubeForme. Each month, subscribers of CubeForme receive a delivery of featured designers’ 3D printed work.Pham, who is majoring in cognitive science and philosophy, politics and law, thought of the idea with high school classmate Nick Nguyen when they were brainstorming ideas for creating their own business.“At first, Nick and I considered using graphic design to make t-shirts, but we soon realized that market was too saturated,” Pham said. “We ended up choosing 3D printing because we were intrigued by the process and figured the average consumer probably was, too.”According to Pham, 3D printing is an entirely different application because it has a steep learning curve. Most people are not familiar with 3D printing, so he and Nguyen wanted to present it in an easier format that anyone could access and understand.The duo reached out to a handful of 3D designers to include in the startup. Their vision was to create a platform that could support these designers while giving consumers the opportunity to physically interact with their products.“I thought a subscription box would be a great way to enter the business field, and Kyle had his heart set on helping artists by featuring them in one way or another,” Nguyen said.According to CubeForme’s website, every month subscribers receive a box that showcases the innovative work of a featured designer. The contents of the box are always a surprise and anything can be inside them, from aesthetic models of figurines to functional objects such as 3D printable clocks.Though subscribers won’t know exactly what they will get, they always have the caveat of knowing the designer beforehand.Luis Picarzo, a mechanical engineer from Spain, is one of CubeForme’s prolific 3D designers.Picarzo found out about the startup when he stumbled upon an invitation in his email.“A CubeForme message appeared one day in my inbox in Thingiverse [a design community],” Picarzo said. “Kyle, the cofounder, explained his new platform with a contagious enthusiasm I couldn’t ignore.”Intrigued by the idea and impressed with the team’s hard work and passion, Picarzo decided to join CubeForme’s initial campaign.“To me, it is a good way to meet new people with similar interests and inspirations, not to mention I get to continue designing things and improving every day,” Picarzo said.According to Picarzo, 3D printing is a form of freedom. He considers it a vehicle for constantly creating new things and hopes CubeForme will continue to help him share his passion.Pham and Nguyen also look forward to raising more awareness about 3D printing. They have already recruited supporters, including fellow students for their team, as well as James Bottom, project director of Blackstone LaunchPad.“I first met Kyle in my freshman startup seminar,” Bottom said. “He later joined Blackstone Launchpad to seek a more customized roadmap for CubeForme.”Blackstone LaunchPad is the largest interdisciplinary entrepreneurial program at USC, and has already coached over 250 student ventures since its opening last spring.“We also have the largest collection of 3D printers, so students can get trained via 3D and 4D printing and create their own prototypes,” Bottom said.According to Bottom, the program not only helps students develop entrepreneurial skills and mindsets, but it also builds a community of creators and problem solvers.Pham and Nguyen both agree that CubeForme’s journey has not always been easy or glamorous, but they’ve been able to learn how to juggle school and workthrough the process.“While there are ‘big’ days like opening up our website or launching our Kickstarter campaign, a majority of the days we’re figuring out mundane tasks such as how to make shipping labels or where to buy boxes,” Nguyen said.Nguyen said CubeForme has received compliments, but some have criticized its business model.“Even though we’ve gotten great feedback and support, we also come across individuals who have 3D printers themselves, and they just don’t see it as something for the broad audience,” Pham said.Nevertheless, with the help of LaunchPad and other USC programs, such as 707Development and 3D4E Club, CubeForme is already on its way to going live.Currently, CubeForme has 47 backers on its Kickstarter campaign and has already reached $1,564 of its $5,000 goal.With just over a month left to go, Pham and Nguyen plan on uploading a visual chart of the backer rewards, so supporters can keep track of the startup’s progress and see an illustration of the rewards they will be receiving.“Our ultimate vision for CubeForme is to make it more than just a subscription box. We want to be a company that connects 3D printing to the greater community,” Pham said.
The eagerly awaited Colgan Heritage Weekend is right around the corner as Inishowen gets ready to celebrate it from June 28 – June 30.

What’s a national park bookstore vendor to do? A beautiful new book of photographs and quotations on Grand Canyon, entitled Grand Canyon: A Different View by veteran river rafting captain Tom Vail, went on sale in the national park bookstore. One would think it would not stand out too much along with hundreds of other items on varying subjects and viewpoints. Yet this one book has come under fire, because it presents a Biblical creationist view of the canyon, reports CNN. If the national park removes the book, it might be accused of censorship, but if it keeps it, the scientific establishment is offended by its interpretation that the canyon is only thousands, not millions, of years old. CNN quotes a spokesman for “Public Employees for Environmental Responsibility” who claims the park is approving a religious book. He claims, “The overall concern is that the top managers of the park service are implementing a conservative agenda that is at odds with their duties as custodians of the nation’s heritage,” he says, which is odd, since the book makes no conservative political statements, but only scientific claims. But can such a book be dismissed on religious grounds? Still smarting from the recent flap over Bible verse plaques at the canyon (07/14/2003), the National Park Service has found a way to censor the book without getting into the quagmire of religious discrimination. It will recommend the Grand Canyon bookstore not restock the book, says CNN, because “the book makes claims that fall outside accepted science — which maintains the canyon is millions of years old.” National Park Service spokesman David Barna thinks this provides a way to remove the offending book without a political or religious fight: “To me, this is a decision you can make that has nothing to do with religion.”Update 01/14/2004: World Net Daily has an article on this story, and so does Nature Jan 15, 2004.1 WND says that the National Park Service has been swamped by emails about it. Apparently the book had been unanimously approved by a panel. Nature, as expected, quotes the American Geological Society calling it a “narrow religious view,” even though numerous PhDs contributed to the book, including several with doctorates in geology. Apparently the flap originated with Wilfred Elders (U of Calif., Riverside), and unnamed others, who got seven geological organizations to complain to the NPS (click here for the statement by the American Geological Society). As a partial compromise, the book has been moved from the science section to the inspirational section of the store. But the author and his allies complain that it discusses scientific evidence, by scientists. Now it’s a neck and neck battle over the email campaigns: NCSE encouraging its members to complain, vs AIG, calling on readers to stop the book ban. Tom Vail, for his part, probably never expected such notoriety. On the bright side, he’s getting a lot of publicity: radio interviews, the CNN story and major newspapers, and lots of hits on his website Canyon Ministries. The Alliance Defense Fund may take up his defense. The Nature editorial is cautious, knowing that censorship can backfire. Rex Dalton writes,Vail says that an alternative to evolutionary science should be offered to members of the public visiting the canyon. “Who is to say whose material should be or shouldn’t be in the bookstore?” he asks. That’s the tricky question that the NPS review will seek to answer, as it weighs issues such as the display of sound science, the right to free speech and the avoidance of censorship charges.Update 01/30/2004: The author has verified a rumor that sales of his book at the canyon stores are really cookin’. So many have asked for the book that the park concessioner is planning to order more. 1Rex Dalton, “National park’s sale of creationist book draws geologists’ ire,” Nature 427, 186 (15 January 2004); doi:10.1038/427186b.This would be a good time to reread Michael Crichton’s tirade against “consensus science” (see 12/27/2003 entry). The upshot of this decision is: only atheists, particularly members of the Darwin Party, are allowed to speak for science. “Millions of years” is now the new standard of “accepted science,” even though secular geologists have been coming around lately that the creationist claims of a young canyon are correct, at least in part (07/22/2002). Tom Vail is a creationist and Bible-believing Christian, yes, but he quotes other creationists who have PhDs in geology who present scientific evidence that the Grand Canyon is not as old as claimed. Having led numerous raft trips down the Colorado River, Vail knows the canyon like the back of his hand. He can personally vouch for all the scientific claims made. Anyone with an open mind who looks at the evidence would surely realize that there are major, serious problems with the “accepted science” view, and the youthful canyon view deserves a fair hearing, whether or not one ties it to a Biblical flood (12/24/2002). One shouldn’t have to subscribe to politically-correct ideology or swear allegiance to “accepted science” to be able to present scientific evidence to support a viewpoint. One should only make the case that it’s correct. Ironically, it is the creationists who argue for letting both sides of the controversy be heard. The evolutionists want to censor any opposition, then grin for the cameras and say, “Controversy? What controversy? I don’t know of any controversy, do you Dr. Joe? There’s no controversy here; why, we all agree. The consensus of scientists is unanimous.” Why not let the public see all the evidence and decide? Nobody at Grand Canyon is shoving the books into visitors’ backpacks. They can pick it up, look it through, and decide whether it is good or bad, without big brother deciding what kind of politically correct science is best for them. The National Park Service is so hypocritical. On the one hand, they fill our parks with exhibits that promote the “consensus science” approach, with its millions of years of slow and gradual evolution. But on the other hand, they have become evangelists for the most anti-intellectual, anti-scientific religion of all: Indian animism (10/10/2000). Hey Mr. Barna: if you are going to allow Native American superstition to have a prominent pulpit in the national parks, why not also allow Bible believers, who respect scientific evidence and logic, to make their case? Either do that or toss out all the Indian myths, and for that matter, any mythology that makes claims about unobservable prehistoric events. The myths that cloak themselves in the term “accepted science” are the most pernicious of all. Visit Grand Canyon before the book is banned. Just the photographs in Vail’s book are worth the price, and who knows, your mind might be opened up a little, if you were raised under Darwin Party teachers. Don’t you just love the PAC titles: “Public Employees for Environmental Responsibility.” Being translated, this probably means, the Government Payroll Lobby Group United Against Bush, Conservatives, the Religious Right, the Iraq War and Free Speech, Who Believe Establishment Science and the United Nations Are the Pathways to All Knowledge and World Peace.(Visited 20 times, 1 visits today)FacebookTwitterPinterestSave分享0

Men on bikes accompanied the march through town, showing their solidarity with women.(Images: Rudo Mungoshi)MEDIA CONTACTS • Nomazwe NtlokwanaDirector: Stakeholder Management, Media Liaisons and Strategy, Gauteng Department of Sport, Arts, Culture and Recreation+27 83 507 8068.RELATED ARTICLES• Businesswomen leaving a legacy• Commemorating 1913 heroines• Women taking SA forward• Educated children help nation to growRudo MungoshiThe courageous women who marched to the Union Buildings on 9 August 1956 in protest against pass laws were honoured for their contribution in a colourful ceremony on the same day 57 years later, in Tshwane.These days, 9 August is National Women’s Day, and although its aim is to contribute to the empowerment of women in today’s society, its roots lie back in 1956 when 20 000 women sought to deliver petitions to then prime minister JG Strydom, and express their outrage at the demeaning legislation that forced black people to carry permits, or passbooks, when travelling outside their townships or designated areas.Even earlier, women a century ago protested in the Free State against the imposition of pass laws – those 1913 protests were led by Charlotte Maxeke.In 1956, the Union Buildings march was co-ordinated by the Federation of South African Women and led by Lillian Ngoyi, Helen Joseph, Rahima Moosa and Sophia Williams-De Bruyn – the only one of the four leaders who is still living.Women throughout the country had put their names to these petitions indicating their anger and frustration at having their freedom of movement restricted by the hated official passes.Reliving the women’s marchGauteng MEC for agriculture and social development, Nandi Mayathula-Khoza, led hundreds of women, young people and community members on a 3.5-kilometre walk to the Union Buildings, the seat of the South African government.They relived the day by walking the same route as the women of 57 years ago.Mayathula-Khoza was joined by MEC for community safety, Faith Mazibuko and the MEC for sports, arts, culture and recreation, Lebogang Maile.The theme for this year’s celebration was Unity in Action for Women’s Socio-Economic Empowerment.At the Union Buildings, Mayathula-Khoza, on behalf of Gauteng premier Nomvula Mokonyane, addressed the crowd who had already gathered to celebrate Women’s Day.Mayathula-Khoza said gender based violence, poverty and joblessness remained the three biggest challenges facing women today.“Sexual violence against women and rape remains a huge challenge in our society. Poverty and poor living conditions have added to women’s vulnerability to violence and increased risk of contracting sexually transmitted infection,” she said.Mayathula-Khoza said the government had strengthened victim support through the existing 200 victim empowerment centres, which offer psycho-social and medico-legal support services, among others.“We have continued placing focus on the Ikaya Lethemba Centre, as we appreciate the positive role the centre has played in helping abused women and children recover and get back on their feet again,” she said.Fighting against patriarchyTshwane mayor Kgosientso Ramokgopa said the fight against patriarchy was not yet over and was manifesting itself differently.“We must restore the dignity of our people and that’s why the struggle of women still remains important,” he said.Ramakgopa also implored young women to stay away from so-called sugar daddies, citing that they destroyed lives.Maile said the sacrifices made by the courageous women in 1956 had made it possible for the nation to make pilgrimages to the Union Buildings to honour their efforts.“Through their commitment, these women are role models for all women and have been a voice for some of our most at risk and marginalised people,” said Maile.The march was followed by performances from leading South African female singers, including Nadine, Mafikizolo, Rebecca and Zahara.

Open-cell foam is not a vapor barrierClosed-cell foam, with higher densities and a higher R-value, can be an effective vapor retarder.But not open-cell foam, It has a perm rating as high as 35 per inch, according to a technical bulletin from Fomo Products Inc.And this, Robert Riversong points out, could be the source of the problem:“The open-cell foam allows water vapor to diffuse through to the cold-at-night roof sheathing where it condenses and runs down, possibly saturating the foam which does hold water,” Riversong writes. “Open cell foam needs to be sealed with a vapor retardant paint. If the installer didn’t inform you of that, he wasn’t doing his job.”Riversong thinks the foam has the potential to absorb significant quantities of water, allowing it to pass through to a cold, condensing surface–the bottom of the roof deck. He argues the foam is a hygrophobic (water repelling) material that morphs into a hydrophillic (water loving) matrix as it cures.When subjected to a standard ASTM test, he adds, an Icynene Inc. foam sample sucked up 34% of its volume in water after 96 hours of submersion. Installed at a density of 0.5 lb. per cubic foot, it has the potential to take in 2 1/2 gal. of water per cubic foot.“I’ve heard of Icynene problems under leaking roofs, in which the foam soaked up water like a sponge,” Riversong says.Whoa, writes GBA advisor Michael Chandler. “Open cell foam is hardly hydrophillic. Leave a chunk of it floating in a bucket of water for a couple of days and see how much water it takes on. Hardly any, I’ve done it.”While Chandler thinks the ASTM test here is inappropriate, Riversong is undeterred.“There are many examples of open-cell foam in walls and roofs that has become so wet from vapor diffusion alone that it could be wrung out like a sponge,” he writes.“An anecdotal report on a blog told of Icynene in a basement ceiling under a bath that developed a leak. When the foam was pulled, the subfloor was black with mold and there were mushrooms growing in the foam.” Spray Foam InsulationThe Icynene Insulation System Ice dams are a familiar problem in New England and other parts of the country where winters are long and cold. Snow on under-insulated and under-ventilated roofs melts, pools and refreezes to form a dam. Water backs up under the shingles and much to the horror of homeowners often finds its way inside the building.Spray foam polyurethane insulation is supposed to be a hedge against that problem. By forming an effective seal around rafters, and offering respectable R-values, foam should be blocking the migration of cold air into the roof where it can condense into water.But a post by a New Orleans resident in our Q&A section showed just the opposite seemed to be happening.Nick had hired a contractor to install open-cell foam on the bottom of his roof deck, converting the attic from a vented to an unvented space. When temperatures dropped below freezing, Nick noticed icicles forming at the soffit near an old, and by then unused, vent for a bathroom fan.The roof itself was virtually new, and neither the insulation contractor nor the roofer could explain what was going on. RELATED MULTIMEDIA The whole roof is not affectedIf vapor permeance was the problem, wouldn’t we expect to see evidence of water over the entire roof deck, icicles forming all along the eaves rather than in an isolated spot?Rich Bev suggestions Nick look for a crack in the condensation line from air conditioning equipment installed in the attic, which may be contributing to a water and humidity problem.“It may be just a direct leak from the A/C to a poorly installed spot in the insulation,” he says.A not-so-hot job of installing the insulation also could be playing its part.Chandler suggests that some installers plug up rafter bays at exterior walls with plastic film so the foam doesn’t leak out the soffits as its applied. But that keeps the foam from sealing wiring and plumbing penetrations in the top plate, he adds, and allows humid air to collect in soffits where it can condense.Taking short cuts as the foam is sprayed can result in voids in the foam between the rafters and the roof deck–another channel for warm air. He suggests a look inside the soffit to make sure the foam has completely sealed the top plate in the wall, and to check that foam has completely filled the rafter bays.“So much of this stuff is about caring enough about the building science to get the details right the first time,” Chandler ways. “Spray foam is ‘hot’ and there are a lot of get-rich-quick types going into green building with little care for quality or integrity.”GBA senior editor Martin Holladay is thinking along the same lines: “Is there any chance that the spray foam has shrunk away from the rafters, leaving cracks that permit warm humid air to contact the cold roof sheathing?” he asks. “Perhaps the moisture transport mechanism isn’t diffusion–perhaps it’s air movement.” RELATED ARTICLES Podcast: How Humid Air Affects A House:Podcast:Air Barriers vs. Vapor Barriers “This leads me to believe that it has to do with the cold weather on the asphalt roof and somehow the warm air in the attic is going through the insulation in that area to cause the problem,” Nick writes. “The question is what can I do to stop the condensation?” GREEN PRODUCT GUIDE Enclosure Overview AtticsSpray Foam Insulation: Open and Closed Cell Does Spray Foam Insulation Out-Gas Poisonous Fumes? Q&A: High humidity issues in a spray foam attic Open-Cell Foam Beats Closed-Cell Foam Our expert weighs inWe invited Peter Yost, the Director of Residential Services for BuildingGreen, to provide his expert opinion on what might be causing Nick’s icicle.Peter Yost’s advice:To identify the source of the moisture, the first step is to determine if the dampness problem is local or general. If the problem is vapor diffusion, the moisture will extend to all (or most) of the roof sheathing. If the moisture is due to a roof leak or an air leak, the dampness will be localized.A clue: The exhaust fan looks awful suspiciousNine times out of ten, moisture problems are caused by bulk water or air leaks. I bet this is one of those nine times. If the moisture occurs in just this one spot — a spot that has a soffit termination for a bath exhaust fan and a condensate line — it’s hard to imagine that this is just coincidence. Even though this exhaust vent was abandoned for a through-the-roof route, are there enough obstacles in this section of the attic at the eave to make the spray foam application in this section less than complete?Pete’s bet: An incomplete foam jobMy first bet would be that the spray-foam installer had a hard time getting a proper airtight application of the foam in this area of the attic. My second bet would be he or she saved this tough section for last; contrary to popular belief, spray foam installations are quite quality-dependent (and even more so with open-cell foams because their expansion is more than three times greater than closed-cell).The pictures of the opened soffit are too close up to really tell us much — other than stuff is wet and probably moldy. Does the opened soffit suggest that spray foam installation in this section of the attic at the eave was deficient?
