Combining Exterior Rigid Foam With Fluffy Insulation

This article is only available to GBA Prime Members It’s becoming increasingly common for builders to install one or more layers of rigid foam on the exterior side of wall sheathing and roof sheathing. Typically, these walls and roofs also include some type of air-permeable insulation (fiberglass, cellulose, or mineral wool) between the studs or rafters.These wall assemblies and roof assemblies perform extremely well, as long as the rigid foam is thick enough to keep the sheathing above the dew point during the winter. (Exterior foam reduces the ability of sheathing to dry to the exterior. Thin rigid foam is more dangerous than thick rigid foam because it isn’t thick enough to prevent moisture accumulation in the sheathing during the winter; however, it’s just thick enough to lower the rate of outward drying.)Guidelines for determining the thickness of exterior rigid foam are discussed in several GBA articles: The thickness of the rigid foam varies by climate zone To prevent moisture accumulation, cold-climate builders need to install thicker rigid foam than warm-climate builders. So the minimum R-value of the exterior rigid foam in these assemblies varies by climate zone.Guidelines for roof assemblies aren’t the same as guidelines for wall assemblies. Why? Because (due to the stack effect) roof sheathing is at greater risk for moisture accumulation than wall sheathing. Moreover, because of nighttime radiation cooling, roof sheathing gets colder at night than wall sheathing, increasing the chance of moisture accumulation in the roof sheathing. These facts lead to more conservative guidelines for roof assemblies than those used for wall assemblies. What about walls with above-code levels of insulation? If you plan to build a 2×4 or 2×6 wall, the guidelines for the minimum R-value of exterior rigid foam shown in Table R702.7.1 in the 2012 International Residential Code — guidelines that…

I’ve seen the future of Facebook, and it is… Yahoo!Between 1994–2000, Yahoo! dominated the consumer Internet industry and much of the world’s attention. The company’s exclamation mark (sometimes called a “bang”) cast a long, purple-hued shadow across the globe, as users flocked to its ever-expanding array of services, and online and offline companies of all sizes threw money at it (almost literally) to gain prominent visibility among its massive, segmentable audience. Yahoo!’s page views rocketed; revenue rocketed; profits rocketed; stock price rocketed; market capitalization rocketed. Yahoo!, it seemed, could do no wrong.Then, the world changed. Radically.What Happened To Yahoo!Consumer behavior shifted, with individuals the world over flirting with, and then devoting themselves to, myriad other online services. The business cycle changed and companies chose/were forced to reduce or eliminate their online advertising budgets. Then, when Internet advertising budgets returned a few years later, business behavior adjusted again, with marketers broadly diversifying their spend across the Web (following those same migrating users). And, perhaps most significantly and most representative of both of the previous issues, Google emerged, presenting consumers with a slate of invaluable (and competitive) services and companies with a nearly perfect mechanism/venue through which to market their offerings.Needless-to-say, the 2000–2013 period has not been nearly so kind to the purple giant-of-yesterday — not to its metrics, its business, its stock or its market capitalization.Throughout its rollercoaster-of-a-life, however, Yahoo! has remained shockingly static at its core, with a (still) massive, segmentable audience consuming an enormous volume of free content and services, surrounded by advertisements of all shapes and sizes. That those content/service offerings now include Fantasy Football and photos from Flickr, rather than, say, news and NASDAQ quotes, is nice, but irrelevant, as is the fact that the company now offers rich media and video ads, as opposed to just sponsorships and banners.Those are incremental changes to the story — variations on the theme; because, the fact of the matter is that — apart from its early days of minimal competition and “easy money” — Yahoo! has struggled mightily to engage its users in fundamentally new ways; unlock the true value of its global user base for its advertising clients; and, bring to market any lasting innovation that even hints at shaking the status quo all over again.In not so subtle ways, this reminds me of Facebook. A lot.What Facebook Is DoingLike Yahoo! in its early phase, Facebook hit the ball out of the park from the outset, and, it seems, hasn’t yet stopped running the bases. From the ivy covered confines of Harvard University, Zuckerberg & Co. now attracts more than one billion users to its site globally; has enabled hundreds of billions of friend connections; sees hundreds of millions of photos uploaded daily; and, generates several billion dollars of revenue annually. Not bad for its first nine years, right?And yet, since its astounding opening act, Facebook has bestowed upon us:Gifting – blah.News Feed algorithm changes – yawn. Suggested Posts – meh. Messaging – join the club. Sponsored Stories – ummm. Graph Search – niche. Poking (again) – ha.Timeline – zzzzz. News Feed design changes – argh.What’s next, a new color scheme? A new font?What Could Happen To FacebookSuffice it to say, the company is not exactly setting the world on fire with these efforts; more importantly, these are not (individually or collectively) doing much (if anything) to materially enhance Facebook’s relationship with its users; substantively increase the level of dependency felt by its advertising clients; and/or fundamentally alter the trajectory of its franchise or business. Said differently, where is Facebook’s second act, like Android (acquired, transformed and massively scaled by Google) or iPad? Where is its money-printing AdWords product? Where is its PayPal (acquired, and massively scaled by eBay)? Where its its quantum leap forward? Where is its disruptive force?None of this is to suggest that Facebook has, in any way, “failed;” nor is it meant to take anything away from the extraordinary space that Facebook has carved out for itself in our collective universe. Similarly, I do not mean to imply that Facebook is necessarily destined to follow in the path of Yahoo! (after all, it would be damned near impossible to repeat all of those mistakes).That said, it is, hopefully, a wake-up call, because — at least to this observer — the company and its business seem far too focused on tweaking the edges of its past creation(s) instead of changing the world all over again for both its users and advertisers. And that, as history might suggest, is a very risky path to enduring success on the Web.Beware the “!,” Facebook. Beware the “!”!

Robin Uthappa made a mockery of Rising Pune Supergiant’s bowling attack to anchor Kolkata Knight Riders closer towards a play-off berth with a convincing seven-wicket win in their IPL 2017 encounter on Wednesday.The right-hander struck a match-winning 87 off just 47 balls and was ably supported by skipper Gautam Gambhir, who made 62 off 46 deliveries, as the two-time champions regained their spot in top of the standings with six wins from eight games.While Uthappa decorated his knock with seven boundaries and six hits over the fence, Gambhir’s innings was laced with six fours and one six.The duo stitched 158 runs off just 85 balls for the second wicket to help KKR chase down the 183-run target with 11 balls to spare.Uthappa, who won the man-of-the-match, said he has settled down with his technique and feeling much more confident.”I have always been strong. I said to somebody a few weeks ago that I have settled down with my technique. I feel confident and I am enjoying myself out there. It is very important to respect the momentum that we have created for ourselves,” Uthappa said.Chasing the target, Sunil Narine (15 off 9 balls) once again got KKR off to a brisk start before he was run out in the third over.Then Uthappa and Gambhir joined hands and took control off the chase with a bit of luck on their favour.Uthappa was lucky to have survived a close LBW call when he was yet to open his account and later when Jaydev Unadkat made a mess of a chance at deep midwicket off Imran Tahir’s bowling with the batsman on 12.advertisementThe stylish right-hander grabbed the opportunities with both hands and thereafter opened his arms to struck boundaries and sixes at will.Uthappa did not spare a single Pune bowler with young Washington Sundar and Unadkat facing the maximum wrath. Uthappa brought up his half-century in just 26 balls in the 11th over.Commenting on his wicket-keeping skills, Uthappa said he can get better with the gloves. He also praised MS Dhoni for setting the standards behind the wicket.”I can get better with the gloves. I am enjoying it though. MS has set the benchmark for all the Indians. Trying to get there, slowly but surely,” he said.
Formula One great Niki Lauda is recovering well after undergoing a successful lung transplant, said the Vienna General Hospital on Monday.Lauda, a three-time champion, has been making continuous progress following Thursday’s surgery. The medical team said that his organs are working well.”Already 24 hours after surgery, Lauda could be extubated, was spontaneously breathing and had full consciousness,” the hospital said in a statement.However, Lauda would need to stay at the hospital to recover fully, which means that he could well spend over a week there.The former F1 driver-turned-businessman had to cut short his vacation on the Spanish island of Ibiza to travel to Vienna as he became unwell.According to Austrian daily Osterreich, Lauda travelled to Vienna when his condition deteriorated after contracting the flu.In 1976, the former Ferrari driver was involved in a serious accident at the German circuit of Nürburgring, sustaining severe burns.He underwent kidney transplants in 1997 and 2005.Lauda was crowned F1 champion three times: in 1975, 1977 and 1984.(With inputs from IANS)
CHARLOTTE, NC – DECEMBER 02: Kelly Bryant #2 of the Clemson Tigers reacts after a touchdown against the Miami Hurricanes in the third quarter during the ACC Football Championship at Bank of America Stadium on December 2, 2017 in Charlotte, North Carolina. (Photo by Streeter Lecka/Getty Images)Earlier this week, Clemson head football coach Dabo Swinney made the decision to name Trevor Lawrence the team’s starting quarterback. That was after Kelly Bryant started the first four games of the season as the team’s No. 1.After breaking the news to Bryant on Monday, Swinney gave the former starter the day off after what Swinney called an “emotional” discussion. According to a new report, Bryant also missed practice on Tuesday sparking rumors.Will Bryant transfer? That’s the question being asked in the wake of the NCAA’s new redshirt rule that allows players to preserve their redshirt status if they play in four or fewer games.Bryant has played in four game this season, thus making him eligible to retain the redshirt. Dabo was asked about the possibility of a transfer. According to the State, Swinney gave the following comments when asked about Bryant:“Certainly if he walked in here today and said, ‘Hey, coach, I don’t want to play the rest of the year unless you’ve got to have me,’ well ‘Ok, if that’s what you want to do, I’m all for it.’ I love Kelly,” Swinney said. “I would be disappointed in that because we need him. But I wouldn’t judge him for that.”Bryant has the option to retain his redshirt and transfer if he so chooses. His absence from a second-straight practice raises questions and we’ll have to wait for more answers.Stay tuned.[The State]
It’s been a trying winter for road maintenance around Nova Scotia. Temperatures dancing above and below the freezing mark are making it difficult for snowfighters at the Department of Transportation and Infrastructure Renewal to know what tool to use to keep roads safe for drivers. In Antigonish County, the department is studying a new tool that may jump-start the melting process and make it easier to clear snowy roads faster. The department is testing a liquid anti-icing process that, if successful, could save money and improve road safety. Anti-icing treatment involves spraying salt-brine solution directly onto the road surface. When the water evaporates, a fine residue of salt is left behind. If applied before a storm, the salt residue prevents snow and ice from bonding to the road. “It’s the same as snow on your driveway,” says Paul Colton, the department’s area manager. “If you drive your car over the snow before you shovel, you find the snow that was pressed down by your tires is harder to remove because it has bonded with the pavement.” The anti-icing treatment stops that bond from forming and makes the road easier to clear. Anti-icing technology is used in other jurisdictions in North America, but is fairly new to Nova Scotia. To make the proper solution, rock salt is added to water until 23 per cent salinity is obtained. The solution is then poured into a 4,000 litre water tank that the Antigonish staff attached to the back of a retired salt truck. For the rest of the winter-driving season, the truck, displaying a large anti-icing sign on the back, will be using the solution on Trunk 4 between Brierly Brook and the Pictou County line, if bad weather is on the way. “Timing of the anti-icing application is the key to having it work well,” says Colton. “We like to get it on the surface eight to 24 hours before a storm, and at a temperature not colder than -5 C.” He says the department’s system of road and weather monitoring stations provide valuable assistance in making the right decision. “It’s definitely helpful to have those modern tools,” says Colton. By getting the road surface treated proactively, Nova Scotia’s snowfighters can help clear the road faster and make it safer. Also, the anti-icing mixture doesn’t bounce or blow off the road when applied, so it can be used more efficiently. Colton says other jurisdictions have reported savings of up to 15 per cent for anti-icing applications, when compared with normal salt use. He says his staff will be monitoring road conditions carefully and recording results. “If it works like they say, we could be adding this process to our toolbox for snow and ice control, not only here but around the province.” -30-
Jalandhar: Reviewing the ground situation in flood-hit villages, Punjab Chief Minister Amarinder Singh on Thursday announced his government would canalise all the rivers with technical support from the World Bank and the Asian Development Bank. Going around Sarupwal in Kapurthala district’s Sultanpur Lodhi sub-tehsil, where the overflowing the Sutlej river led to a breach in the Dhusi embankment, affecting 62 villages, he also promised due compensation to the affected farmers as soon as the water recedes and special ‘girdwari’ (loss assessment) is completed. Also Read – Uddhav bats for ‘Sena CM’ Talking to the media after an aerial survey to assess the damage caused by flooding in Kapurthala and Jalandhar areas, the Chief Minister announced a project to project to realign river streams and courses, besides strengthening and widening of the river embankments for a permanent solution to the problem of floods. Amarinder Singh also announced dedicated village relief teams in the affected areas. Each team would comprise officers of the Health, Civil Supply and Animal Husbandry Departments, and would ensure regular and timely supply of food, medicines and fodder for all affected families.

Amarinder Singh, who earlier conducted an aerial survey of flood-affected areas of Nawanshar and Ludhiana, told reporters in Gidderpindi in Jalandhar district that even if the Central government fails to extend support, the state would ensure full support to every person affected by the flooding. The Chief Minister had written to Prime Minister Narendra Modi on Wednesday, seeking a special flood relief package for the state. Amarinder Singh inspected the breach site in Gidderpindi, resulting from release of excess water from Bhakra dam. For the first time, Bhakra, which normally gets filled to its permissible storage level of 1,680 feet by September, was overflowing in August, he said. The Chief Minister, who is constantly monitoring the flood situation, further ordered the Drainage Department to immediately identify potential breach points and plug those on priority.
Le Pérou perd chaque année 150.000 hectares de forêtPérou – Chaque année, le Pérou perd quelque 150.000 hectares de forêts en Amazonie, soit l’équivalent de 15 fois la superficie de Paris intra-muros. Un chiffre inquiétant, dû à l’agriculture nomade, aux activités illégales, mais aussi à la récente découverte de réserves de pétrole dans le nord du pays.Cette catastrophe écologique est dénoncée dans un récent rapport du Défenseur du peuple, un organisme chargé de défendre les droits constitutionnels. La déforestation de l’Amazonie péruvienne “s’explique par la pression de l’agriculture nomade, le développement désordonné de ce territoire et les activités illégales” déplore Beatriz Moreno, directrice de l’organisme.À lire aussiLes tamanoirs, des animaux plus dangereux qu’ils n’en ont l’airLe Défenseur du peuple dénonce certaines “faiblesses des politiques forestières des institutions gouvernementales”. Alors que la moitié du pays sud-américain est couverte de quelque 68 millions d’hectares de forêts, la déforestation est “absolument inacceptable parce que le Pérou est le neuvième pays au monde en termes de richesse forestière et le quatrième en termes de biodiversité” s’insurge Beatriz Moreno.Les terres péruviennes sont également de plus en plus convoitées par des multinationales, depuis la découverte il y a quelques années de réserves de pétrole abondantes. Ainsi le groupe franco-britanniquePerenco,installé dans le bassin de Marañón, entend-il par exemple investir près de 1,4 milliard d’euros sur 4 ans dans le développement de ses exploitations pétrolières.Beatriz Moreno appelle le gouvernement à réagir immédiatement, lui rappelant que les forêts, concentrées à 91% en Amazonie, constituent une “source de revenu et un symbole de l’identité culturelle des peuples indigènes”. L’Amazonie, trésor de biodiversité, est également un rempart de taille contre le réchauffement climatique mais aujourd’hui, la déforestation est à l’origine de 20% des émissions de gaz à effet de serre mondiales.Le 31 juillet 2010 à 19:13 • Emmanuel Perrin
Sables bitumineux : des émissions de gaz à effet de serre triplées en 2020D’ici à 2020, les émissions de gaz à effet de serre liées à l’exploitation des sables bitumineux en Alberta auront triplé. C’est du moins ce que révèle une récente étude publiée par le ministère de l’Environnement canadien.Si le Canada tente de redorer l’image de l’exploitation des sables bitumineux, considéré comme la méthode de production de pétrole la plus “sale” qui existe, une étude publiée par le ministère de l’Environnement canadien prévoit une augmentation considérable des émissions de gaz à effet de serre engendrées par cette exploitation. D’après cette étude, les émissions devraient tripler au cours de la prochaine décennie, pour atteindre 92 millions de tonnes, contre 30 millions de tonnes en 2005, révèle le site du New York Times.À lire aussiQui est Greta Thunberg, proposée pour un prix Nobel à seulement 16 ans ?Cette augmentation des émissions devrait bien plus que compenser les réductions réalisées dans d’autres domaines, comme la production d’électricité, souligne l’étude. Un constat qui fait “clairement comprendre que les sables bitumineux ne feront que continuer à être l’un des problèmes majeurs du pays en matière d’émissions au cours de la prochaine décennie et au-delà”, souligne Simon Dyer, de l’Institut Pembina, qui étudie les questions énergétiques et environnementales.En décembre 2009, lors du sommet de Copenhague, le Canada s’était fixé pour objectif de réduire ses émissions de gaz à effet de serre de 17% à l’horizon 2020, et ce par rapport à leur niveau de 2005. Mais l’étude publiée par le ministère de l’Environnement révèle que le pays n’atteindra pas cet objectif. Au vu des estimations actuelles, seulement un quart des réductions nécessaires seront réalisées d’ici à 2020.Le 11 août 2011 à 11:27 • Maxime Lambert

Enlarge ImageFord’s new Bronco could help bring back another historic SUV nameplate. Ford Ford has been whipping truck and SUV enthusiasts into a froth with the news of a revived Bronco SUV, but it would seem that Bronco isn’t the only famous nameplate that’s getting a second lease on life.According to a report Saturday by FordAuthority.com, the Blue Oval has applied for trademarks on both the Scout and Bronco Scout names, and we’re betting that the Scout badge could find a home on the long-rumored “baby Bronco.”Now, applying for trademarks on vehicle names isn’t necessarily a sure sign that they’ll get used. Automakers squirrel away weird names for potential vehicles all the time. That said, the fact that it’s trying to snag a trademark on a famous SUV name like Scout leads us to believe that this is more than just an exercise.Unfortunately, details on the Bronco are still scarce as Ford has gotten annoyingly good at stopping leaks (for the most part) about its highly anticipated new vehicles. We are reasonably sure that we’ll see the new Bronco sometime next year as a 2021 model, with the baby Bronco (likely Escape-based) a few months after that. 2020 BMW M340i review: A dash of M makes everything better 2020 Hyundai Palisade review: Posh enough to make Genesis jealous Ford Tags Ford’s iconic Bronco throughout history (pictures) 2020 Kia Telluride review: Kia’s new SUV has big style and bigger value 12 Photos
