How to Build a ‘Perfect Wall’

admin tipstjdveffr , , , , , , ,

first_imgSorry, this wall system isn’t ‘perfect’For starters, Brett Moyer points out, there are three problems with the wall system Homoly is proposing, leaving it something short of perfect. He cites these shortcomings:â— There is “zero moisture buffering capacity.”â— The Zip System is expensive and unlike more traditional methods it relies on tape rather than overlapping layers of material to keep moisture out of the wall. Further, Huber hasn’t revealed what the perm rating of the material is.â— There’s no need to use petrochemical foam where it isn’t needed.Moyer seconds a suggestion from Armando Cobo, who recommends cellulose insulation in the wall cavities rather than foam. As does David Meiland, who says he sees “very little benefit to the foam, especially low-R-value open cell, with a lot of risk and cost if/when something gets wet.”Cobo’s recommended wall would include a weather-resistant barrier (WRB) over the sheathing, then the windows, the rigid foam, a ventilated rainscreen and then the wall cladding. Or, Moyer adds, Homoly could save money and eliminate the flashing issues by using a double wall or a Larsen truss; either system can defeat thermal bridging in the same way that rigid foam does. Where Does the Housewrap Go?Nailing Window Flanges Through FoamFastening Furring Strips to a Foam-Sheathed Wall RELATED MULTIMEDIA PODCAST: The Perfect Wall, Roof, and Slab Why is cellulose better than foam?Homoly, however, isn’t ready to abandon ship on the foam.“It seems to me spraying a wet substance into a wall is just a bad idea in general,” he writes. “Surely the wall insulation will settle over time leaving gaps at the top (physics working against it). It won’t be able to fill cavities like an expanding foam. I would think newspaper will mold if it gets wet.”Open-cell foam, on the other hand, seals cavities more effectively, repels water, and will permit drying if the wall gets wet, Homoly says. Although it doesn’t have the high R-values that closed-cell foam has, it’s more forgiving. “I would certainly pick cellulose over batts,” he adds, “but not over foam.”Cellulose is preferable for a number of reasons, Cobo replies. It has a much lower global-warming impact than foam, should not settle if installed correctly, and it’s cheaper. In addition, cellulose can absorb some moisture at times of high humidity and release it when the air dries out.Although foam makes sense in some situations — at the hard-to-insulate connection between floor joists and rim joist, for example — it’s not the best choice every time.Further, Cobo says, the 1 1/2 in. of rigid foam Homoly is planning is a minimum; 2 in. would be better for the Kansas City climate. “The rigid foam outside of the sheathing and on top of the roof decking for a conditioned attic is for thermal bridging and to keep condensation to build on the inside of the wall and roof sheathing,” Cobo writes. “You also should install your wall and ceiling sheetrock with an Airtight Drywall Approach or ADA.” CONSTRUCTION DETAILS Flashing/Window Installations Andrew Homoly is building a house in Kansas City, Missouri, and plans to use a “perfect wall” system consisting of 2×6 studs, Icynene open-cell foam insulation and an additional 1 1/2-in. layer of rigid foam on the building’s exterior.His question in this Q&A post at GreenBuildingAdvisor concerns the best way to install window and door flashing, and where to install housewrap.“Should the window flanges go over the foam at the window openings or should you line the window openings with a 2×4 so the window can be mounted into a solid piece of wood?” Homoly asks. “This would provide a more stable connection, but negates the benefit of the thermal bridging provided by the foam.”Homoly is planning on using Huber’s Zip wall system under the rigid foam, and applying housewrap over the foam, an approach he recognizes as “a bit overkill” but reassuringly redundant.The debate over how best to attach and flash windows in walls with exterior foam has been going on for years. What does the forum have to say? That’s the topic for this week’s Q&A Spotlight. Attaching windows and sidingOne of the reasons Homoly isn’t eager to increase foam thickness is the difficulty of attaching siding, shingles, and trim. “I could see siding and shingles flying off much easier in high winds (I am in tornado alley),” he writes. “Unless there is some kind of excellent new technique for attachments through this amount of foam, I don’t feel comfortable beyond 1.5 in.”Cobo wonders whether an engineer’s report would be required for attaching Hardie fiber-cement siding through foam any thicker than 1 inch. But GBA senior editor Martin Holladay assures him that the calculations for attaching furring to foam up to 4 in. thick have already been published by FastenMaster. “I think your worries are baseless,” he says.As for installing windows in a wall sheathed with rigid foam insulation, Holladay points to several articles he’s written on the topic. They explain how windows can be installed in the same plane as the back of the siding (“outies”) or in the same plane as the sheathing (“innies”). Both methods can work, and Holladay offers step-by-step instructions in a related blog. Video: Superinsulating a Home with Rigid Foam RELATED ARTICLES Our expert’s opinionWe asked GBA advisor Michael Chandler for his take on this question. Here’s his response:The important thing here is for Andrew to feel comfortable in his house. If he intuitively feels that more than 1 1/2 in. of foam would leave him vulnerable to wind damage, then he should stay with a system that makes him feel comfortable. But in my opinion, he should think through a few other issues.First, he doesn’t need to provide more than 1 1/2 in. of attachment for his window’s nailing flanges, so “outie” windows can hang on 2x2s screwed to the sheathing. Doing this doesn’t “negate” the thermal break at all the studs and rim joists, and you already have the thermal break of the window frame that you are accepting as part of the cost of the solar gain and daylighting.But if he is planning on wrapping the house with OSB, then I would recommend that he question the Huber ZIP and just use regular OSB and housewrap, nail the window flanges to the OSB, and do the regular housewrap detail. Then he can build up exterior jamb extensions and run the foam and tape those seams if he likes — or not. That’s much easier than using flex wrap to get out onto those 2x2s.As for the foam versus cellulose isse, I think it’s a good idea to question spray foam in this assembly. But damp-spray cellulose isn’t the only alternative. You can also do a blown-in-batt approach with a scrim and dense-packed (dry) cellulose or dense-packed (dry) Spider micro-filament fiberglass, either of which has the same R-value as open-cell foam.I prefer the Spider because it doesn’t hold water in the event of a bulk water leak (I’m in hurricane alley, so I relate). At Johns Manville’s Spider website they are all about promoting their damp-spray application but the scrim and dense-packed Spider is cheaper and better in my opinion.Finally, I’m a big fan of double-wall construction. it’s surprisingly inexpensive, storm-worthy, and I think it would be good for your locale. But the extra-thick walls are an acquired taste aesthetically, and if that’s not your thing, the 2x6s with 1 1/2 in. of foam and “innie” windows is a great, if perhaps not perfect, solution.last_img

Japan’s offload king Tim Lafaele on his wrestling inspiration

first_imgLATEST RUGBY WORLD MAGAZINE SUBSCRIPTION DEALS The Japan centre is famed for slick passing but exploits in the ring have spurred him on Asked to recall his favourite offload, he quickly responds that his flick against Russia in the World Cup opener was a moment to treasure. For those who had followed Japan in the build-up, playing with such freedom as they would go on to do against European powers like Ireland and Scotland should not have been a surprise.Related: Inside the vital 24 hours before Japan v Scotland“The coaches, Jamie Joseph and Tony Brown, encourage boys to play with their own style,” he explains. “It’s good feet, they encourage the boys to have a crack all the time. And it’s in games, not just at training. Having the confidence from the coaches means heaps when you go out to express yourself.“Tony Brown, when he takes our backs and we’re doing passing drills, we’ll be doing normal passes and he’ll chuck in, ‘Nah, boys, this time all the passes have to be around the back – keep practising that.’ So everyone’s trying it and most guys have one good arm and one bad arm…!”Lafaele says he was surprised when Joseph and Brown first called him up to the Japan set-up, but he has been nurtured and encouraged since. He made his debut in 2016 and has started 22 of his 23 Tests. And while Fale has helped him set goals, he has had plenty of on-field mentors too. Tim Bateman and Andy Ellis have helped him out, while seeing Dan Carter at close quarters was also beneficial.In Europe: Playing against England in 2018 (Getty Images)Then there is the coach work of Wayne Smith at the Steelers, who Lafaele praises for his communication skills, his rapport with the athletes. Asked why Smith is so coveted, so influential, the back adds: “You’ve got all these other coaches trying to make up moves and stuff but if you run, use hands, you’ve just got to be square. It’s running good lines. It’s keeping stuff simple so the boys can understand easily and execute easily.”During lockdown, though, clubs have been good at letting Japanese Test players focus on programmes remotely, to align with national plans. Lafaele has been back in Auckland, helping out his family there, but he has his eyes set on a bright future for the Brave Blossoms. Key to that, for him, is Japan getting to compete with the best of Europe in November.“I’m pretty excited and keen to get involved if that tournament does go ahead,” Lafaele says of unconfirmed stories about Japan’s involvement in an eight-team tournament in Europe in November. “I want to carry on that momentum from last year but also our boys are working hard at the moment as well.”He believes that after the highs of the World Cup and the buzz around Japanese rugby – it was an interesting experience to be recognised on the way into Wrestle Kingdom, for example – it is time to capitalise. He also wants to improve on his game, being smarter and more ruthless at the contact area while maintaining his ability to slip a pass. Think of the savvy Conrad Smith, he says.It’s time to show off a bit more of his ring craft. Can’t get to the shops?

On the field of play, though, Lafaele is a willing showman. Offload king Tim Lafaele on his wrestling inspirationLike oh-so many Samoan kids, Tim Lafaele was a fan of wrestler Dwayne Johnson growing up. He could smell what The Rock was cooking.Yet the story of his early life was one punctuated by transition and rugby. Lafaele was sent to Auckland at just four to be adopted by his uncle, while his father remained in Samoa, hoping young Timothy would prosper abroad. Having missed out on the Auckland rugby academy, in his last year at De La Salle College, Lafaele would get the opportunity to move to Japan, for a four-year scholarship at Yamanashigakuin University.Today, he is settled. It has been 11 years since Lafaele, 28, left for Japan and in 2019 his offloading antics for the Brave Blossoms on an incredible 2019 Rugby World Cup sent tongues wagging. And all the way there it was rugby propelling him, the pursuit of a professional contract the initial motivator.He would move to Fukuoka to join the Coca-Cola Red Sparks out of university and then later the Kobe Kobelco Steelers, as well as featuring for the Sunwolves and of course the Japan national team.“I’d never heard of it at the time,” Lafaele says of Japanese rugby scholarships and his early experiences. “But when I got there, there were so many other guys doing it.“I didn’t know much about Japan – all I knew was the big city, the big lights. But when I went there it was a totally different part of Japan, out in the country! It was a bit of a shock at the start as I didn’t know how to speak Japanese.“The training was a lot different to New Zealand too. It was long. We’d have three or four hour-long training sessions in the afternoon. We’d do training in the morning before you go to class and after that the three or four-hour training.”World Cup wonder: Offloading during Japan’s win against Ireland (Getty Images)Pushed by his family to go out and see the world for himself, he relished the rugby opportunity. However, we all crave something familiar and it is here where the life of a wrestler really captured him.Toks ‘Bad Luck’ Fale is a founding member of the Bullet Club stable of performers, in New Japan Pro-Wrestling. He is also a De La Salle alumnus who took up a Japanese university scholarship and went on to play professional rugby in the country, at the Fukuoka Sanix Blues (now Munukata), before injury curtailed his career and he turned to a life of grappling. Fale has served as something of an inspiration to Lafaele.The centre says of his friend: “In my last year of high school we went to a tournament in Japan. He (Fale) stayed in the area, in Fukuoka, and I met him there. We kept in contact. Then when I went over to Japan for university I contacted him.“He basically helped me, talked to me when I needed help or extra motivation. He’d tell me to keep writing my goals down and to aim for them.“When I first went over to Japan in 2010, that’s when he was a ‘young lion’ – that’s what they call them when they start going into the dojo – and he’d just started up then. He made his debut that year. Starting out he was at the bottom but it only took him like a couple years until he was at the top with the Bullet club. Seeing him do that, man it just motivated me to try to do the same with my rugby.“Seeing the struggles he went through to get to where he is now motivates most of the guys from my school when they see his story.”Inspiration: Lafaele and Tui temporarily join the Bullet Club (pic: Tim Lafaele)Shortly after the World Cup, the 6ft 5in and 130kg-plus Fale invited Lafaele and team-mate Hendrik Tui to sit ringside for an event at Wrestle Kingdom. Then closer to time, Fale asked the pair if they would like to walk the competitors out to the ring.The two rugby stars were jacked at the offer, but when they got backstage it dawned on them that they did not know the proper etiquette for such a role. Panicking, they laughed and asked each other at the curtain, “How are we going to do this?!” Ring kings: Lafaele (left) with Hendrik Tui (far right) at Wrestle Kingdom (pic: Tim Lafaele) last_img

Jonah Lomu Documentary – Part 2

first_imgThursday Oct 2, 2008 Jonah Lomu Documentary – Part 2 Following on from our recent posting of Part 1 of the Jonah Lomu short documentary , the much anticipated Part 2 of this insightful video features more thrilling action of the legend in action, with plenty of tries and behind the scenes commentary. If you haven’t been able to watch Part 1 yet, please make sure you do as these two clips combined make for a fantastic 30 minutes of high intensity footage that will bring back many memories for some, and astound others. Kicking off with the sensational 1999 World Cup performance where he terrorised England once again, who could ever forget the words of Keith Quinn as Lomu barged over the tryline to score. The Semi-Final against France in the same year will be remembered for two things – France’s incredible comeback victory, and Jonah Lomu. Lomu was a man against boys as his pace, power, and grit combined to bash off all in front of him, including big french number eight Abdel Benazzi. We then follow Lomu as his move to Wellington makes a huge impact, both literally and figuratively. Along with teamates Tana Umaga and Christian Cullen, Lomu is simply unstoppable the majority of the time, with the majority of defenders almost opting to get out of the way rather than stand in front of the runaway train. Jonah’s ability to offload in the tackle, providing the scoring pass, was one of his most fascinating aspects, as he provided many tries for team mates in that manner. It was an element of his play that back then, and even today, sets him apart from the other big wingers of the game. It’s sad that at his current age of 33, Jonah should still be out there doing what he loves, but hasn’t been able to. Destiny saw it otherwise, and what we’re left with is fantastic memories of the man who was the games first real superstar of global proportions. Jonah single handedly changed rugby, and for that, the great man deserves all the praise and respect shown to him as he enters the next chapter of his life. The footage doesn’t go into Jonah’s years of suffering with the devastating illness that effectively ended his career, but that’s probably for the best as we want to remember the good times. We hope you enjoyed this awesome two part documentary.Time: 14:24 ADVERTISEMENT Posted By: rugbydump Share Send Thanks Sorry there has been an error Related Articles 81 WEEKS AGO scottish prop saves fire victim 84 WEEKS AGO New Rugby X tournament insane 112 WEEKS AGO Vunipola stands by his comments supporting… From the WebThis Video Will Soon Be Banned.
