" OK so we're now sheathing. The back portion of this through. And joining me is Brian readling from the APA engineered wood association -- a little bit about the new technology some of these materials we just we're looking at the clips Brian that are on the rafters as they join the top plate of the law right and that's these little things here. What's the purpose cities. Basically that enables us to load the nail instead of pulling the nail out like a traditional plan now. These clips. Act to shear the nail off or shear the head of the nail with. -- a lot more strength than just simply pulling them out that's -- nail is driven and horizontally. Into two members either down and -- on -- down into the trap them and that gives it more strength. And when there is a hurricane situation that it does and it could bring opera house this government. Look how to prevent -- all part of our continuous load path that we need all the way from the copper roof. Following him of the foundation right we've looked at another ask except on the way out -- the Techshield is a product that we're using to achieve there via the roof but."

" Essentially a plywood. With a reflective surface and I've got it upside down here that we could look at -- this will be flips out and the reflective surface faces the attic space. Now this is up -- hot weather product this is not something that's designed for cold climate. But rather for areas where you can reduce the amount of heat gain into the attic space after thirty degrees. Because this will actually act as a mirror it will radiate the heat right back through the plywood -- the shingle and won't let it get into the attic space so it's a real energy saver."

" What about how it should be attached Brian. A -- in originating in how wind area like and here's credible a low slope roof the lower the slightly more uplift you now. And in this case we would recommend a ring shank nail be used -- health and additional withdrawal capacity right. And that would be located at four inches on center along approached the into the panel and six inches on center. Along the intermediate framing members and the point of the ring shank is a little bit like. Like a screw it's not quite a screw. But it does grip won't slip back out of wood has a lot more withdrawal value than last thing right and what about it -- do we recommend the use any kind of panel adhesives. On the sheathing we don't really recommend. The use -- an adhesive because that tends to squeeze out in the panel joints. We like those joints to maintain a 18 of an inch space. That the panels can expand. Or less an expansion joint with a piece of in that joint and restrains the panel expansion. However as I understand it the the sheathing system of Rubin hurricane. Can still keep a lot of water most of the damage in hurricane is from water right insurance industry studies that -- That once the roof covering -- refitting of loft. And water comes into the building lost about 80% of the total value of our structure and its contents. One of the products that's that's kind of being seen more and more. This peel and seal about ten minutes membrane. That's stuck across the panel joints. To keep the the rain out if the recovering well. This seals the the joints of the plywood. Or of the OSB says that water doesn't run between the joint news here now now the fact that they have a shiny side and it is. So ridiculous incident it has nothing to do the Chinese night on the yeah. The Techshield."
