The Premier Soccer League (PSL) announced the list of nominees in Johannesburg on Thursday. The three players represent the top three teams in the PSL standings, but only Vilakazi and Katsande are up for the Absa Premiership Players’ Player of the Year Award, with Teko Modise of Mamelodi Sundowns being the other nominee. Vilakazi is also in the running for the Nedbank Cup Player of the Tournament, along with his team-mate Jabulani Shongwe and Oupa Manyisa of Orlando Pirates.Coach of the Year Sundowns’ coach Pitso Mosimane faces Stuart Baxter of Kaizer Chiefs and Clive Barker of Mpumalanga Black Aces for the Absa Premiership Coach of the Year Award. All three men are former Bafana Bafana coaches. While Sundowns and Chiefs will finish one and two in the PSL standings, Barker has surprised by taking unfashionable Black Aces to sixth on the table heading into the final weekend of league action. The Absa Premiership Goalkeeper of the Season Award will be decided between Bafana Bafana and Kaizer Chiefs’ skipper Itumeleng Khune, Ajax Cape Town’s Anssi Jaakkola, and Moneeb Joseph’s of Bidvest Wits.Young Player of the Year The Premiership Young Player of the Year is between the Ajax Cape Town duo of Abbubaker Mobara and Keagen Dolly and Bloemfontein Celtic’s Gabadini Mhango.

The Cloud Made Open Source “Invisible” This Year

It’s not that the media stopped reporting on open source Asay explains. In fact, according to Google News, the number of stories mentioning the phrase “open source” roughly doubled. What’s happening is that open source is moving behind the scenes, thanks in large part to cloud computing.Asay wrote:Hence, for example, 2010 was the year that we talked a great deal about NoSQL citizens like Cassandra and MongoDB, but not so much because of the companies formed to monetize them (Riptano and 10gen, respectively), but rather because of the exciting web applications built using them.These web applications, mostly built using open-source technologies like Hadoop and Lucene, have turned the idea of an operating system on its head. Or rather, in Tim O’Reilly’s words, the operating system is now “the whole web.”Asay makes a really interesting point: open source hasn’t destroyed the dominance of proprietary software. Instead, open source projects are primarily funded by the proprietary profits of companies like Facebook, GoogleYahoo!It’s a brave new world for open source, and not the one that Richard Stallman envisioned 27 years ago. In fact, he’s now cautioning people against the cloud (our own Alex Williams echoed some of these sentiments in his open letter to Google today).Where do you think open source will be going next year?last_img read more

How to Insulate a Cathedral Ceiling with Mineral Wool

Posted on by

first_imgOur expert’s opinionPeter Yost, GBA’s technical director, had this to say:Roof assemblies, like wall assemblies, should be designed and insulated to dry in at least one direction. We tend to focus on how building assemblies get wet from interior moisture during the cold winter months, but more importantly, we have to focus on how they dry from any of a variety of moisture sources, not just wintertime interior relative humidity.Roof assemblies are like wall assemblies that never get stood up straight. So, while they do see more bulk water, they can be designed and insulated without back-venting the roof sheathing (“hot roofs”), just as walls are. There are two critical elements, however: selecting materials for ALL layers that collectively create directional drying AND a continuous and contiguous (to the insulation) air barrier in the unvented roof assembly.On the other hand, back-venting the roof sheathing is a more forgiving approach, if the soffit-to-ridge vent chutes are continuous and well-sealed with respect to the roof cavity insulation.You can “decouple” the roof cladding and roof sheathing (in terms of wetting and drying) from the rest of the cathedral roof assembly with either a top-side air space or a vent chute underneath the roof sheathing. Each presents construction detail challenges, and costs. And frankly, the choice of roof cladding material and your climate can strongly suggest just how important some sort of venting is to the performance of the roof assembly. For examples, see this article from Building Science Corp. as well as this one.For more information on vapor profiles and drying, take a look at this blog. CONSTRUCTION DETAILS RELATED ARTICLES First, will that be enough insulation?Whether unvented cathedral ceilings should be dense-packed at all is a question that’s generated plenty of discussion in the past. Leaving that aside for the moment, a key question for Roy is whether mineral wool packed into a 2×10 rafter bay will provide enough thermal insulation for his locale, and the answer is no, it won’t. What about a vapor-permeable chute?If the ventilation chute carries away any excess moisture from the cavity insulation, Thomas Jefferson says, it would seem “wise” to make the baffle with a vapor-permeable material.“Foil-faced polyiso does add R-value but it’s not permeable,” Jefferson says. “I’d suggest hardboard (Masonite) or another fiber panel to just hold back the dense pack without impeding water vapor. The dense-pack will be only ~R-31, so you’ll need to furr out below the joists or add polyiso below, as Martin suggested.”Holladay disputed Jefferson’s opinion that “this vent chute serves partly to carry out any excess moisture from the cavity insulation.” According to Holladay, “No one wants interior moisture migrating through the insulation to the ventilation cavity — certainly not deliberately,” he says. The idea is to prevent any moisture from getting into the ventilation cavity and to provide a mechanism that helps keep the roof sheathing dry.“The purpose of the ventilation channel is to lower the humidity of the roof sheathing — in case some sloppy carpenter did a bad job of caulking the ventilation chutes in place, or in case some electrician mistakenly installs wiring or a can light in your ceiling,” Holladay says.Isn’t the purpose of a ventilation chute to prevent the accumulation of moisture? asks Jefferson. “Moisture can come from a few different sources, and one could be below the chute,” he says. “Why design a vent chute to intentionally exclude water vapor that just might find itself in the cavity insulation? Not that it’s intentional for the insulation to be damp and need drying to the exterior, but the opportunity of drying reduces risk.”Not really, Holladay says: “The purpose of the ventilation channel is as a last-ditch method of keeping your sheathing dry in case your assembly has flaws. But you don’t want to build in any paths that allow or encourage vapor to flow toward your cold sheathing.” Spray-in foam works, tooGiven the difficulties of building in an effective ventilation chute, Roy asks, what about the possibility of using closed-cell foam directly on the underside of the roof sheathing?Closed-cell foam provides an air barrier, but to control condensation it must be applied to a minimum R-value, depending on what climate zone you’re building in, Holladay says. That ranges from R-5 in zones 1-3 to R-35 in zone 8. Making airtight ventilation chutesThe most effective ventilation chutes will be site-built, Holladay says. “Usually, the builder starts by tacking up 1″x1″ sticks in the upper corners of the rafter bays,” he writes. “Then rigid material (Celotex, thin plywood, or rigid foam) is installed against the sticks, with caulk or spray foam to make the installation airtight.”While providing an excellent air seal, these chutes are not the fastest to install, Holladay says.M S says chutes might be made from sheets of polyisocyanurate foam insulation, sealed at the seams with spray foam. The foam would simultaneously serve as baffle and insulation. By dense-packing the remainder of the rafter bays with cellulose, at R-4 per inch, the roof would be rated at R-39.“Now, as Martin suggests, overlay the face of your studs with rigid insulation, either polyiso or XPS,” M S says. “Putting up another 2 in. of polyiso gets you close to R-52.”center_img As GBA senior editor Martin Holladay points out, a 2×10 is really 9¼ in. deep. Using the values published by the National Association of Home Builders Research Center, mineral wool at a density of 2½ pounds per cubic foot would have an R-value of about 34 if it completely filled the rafter bay.The 2006 International Residential Code requires ceilings in Roy’s area (Climate Zone 5) to be insulated to at least R-38, Holladay says.If part of each rafter bay is dedicated to an air chute, reducing the amount of insulation that can be added, the numbers get worse. This means that whether Roy adds air chutes or not, he’ll need to find a way to add more insulation if he wants to meet IRC requirements. Q&A: Joe Lstiburek says, Don’t dense-pack unvented cathedral ceilings Q&A: Green way to insulate cathedral ceilings? Q&A: Is dense-packed cellulose an air barrier?Insulation Overview Debating the merits of ventilationDespite assurances from the insulation contractor, building codes won’t allow the kind of roof assembly Roy is contemplating.“According to my understanding of the International building codes, you can’t install an air-permeable insulation like mineral wool in a cathedral ceiling unless you first install ventilation chutes on the underside of the roof sheathing,” Holladay says. “Styrofoam ProperVents are too flimsy to withstand the pressure of dense-packed insulation, so you’ll probably want to install plastic AccuVent or site-built ventilation chutes.“It doesn’t make any sense to install soffit vents if you don’t have ventilation chutes between the top of the insulation and the bottom of the roof sheathing,” he adds. “If it were my house, I would install ventilation chutes (well sealed to prevent air leakage). I would also install 2 inches of foil-faced polyiso under the rafters, held in place with 1×4 strapping, and I would blow the mineral wool through holes in the polyiso.”A poster named M S directs Roy to an article by building scientist Joseph Lstiburek of the Building Science Corp., who says flatly: “As fantastic as the dense-pack approach is for walls, it is a pretty dumb approach for unvented cathedral ceilings and flat roofs. And, no matter how hard some of us work to try to stop people from going ahead and doing it, they persist on doing it. First, it is a building code violation. Second, it violates the physics.”It would seem Roy should abandon ship on whatever plans he had for dense-packing an unvented cathedral ceiling. So what’s the best way of adding ventilation? John Roy is building a house in southeastern Massachusetts, and at least part of it will have a cathedral ceiling. He’s thinking of insulating the ceiling with dense-packed rock wool.The president of a local insulation company tells him there’s no need to install air chutes in the rafter bays before the insulation is blown in because the insulation does not absorb water. The local building inspector is prepared to go along with the recommendation providing soffit vents are installed.Is Roy getting good advice? That’s what he’s asking in this Q&A post, the subject of this week’s Q&A Spotlight. Roof/Wall Connections for a Cold Climatelast_img read more
