![]() ![]() A single plate attached to a wooden deck is ideal. Wall construction is a three-part process that’s different from stick framing, yet easy to master: lay down a couple of beads of expanding polyurethane foam on the wall plates attached to the floor deck hoist a panel upright so it straddles the plate plumb the panel and nail it through the OSB into the edge of the plate. Although SIPs are used for both walls and roof structures, wall applications are the simplest and most appealing for first-time SIPs builders. The foam along panel edges is factory-recessed back from the OSB skins so SIPs panels can interlock with bottom plates, top plates, and neighbouring panels. You’ll typically find them in 4 1/2, 6 1/2 and 8 1/4-inch thicknesses, ranging from 8 to 16 feet in length, strapped together in plastic-wrapped bundles about four feet high. SIPs are made in a handful of plants around Canada and shipped out via transport truck. You can learn more about panel availability from the nonprofit Structural Insulated Panel Association (25). Structural support, insulation and vapour barrier all go up at the same time. Tilt them upright so they straddle the bottom plate, plumb them, then nail the OSB flange to the bottom plate and any adjoining walls. Wall panels generally come in 4-foot wide sections, 8, 9 or 10-feet tall. It goes up fast while demanding much less skill than stud-frame work. SIPs are also impervious to internal condensation (no need for a vapour barrier), yielding a virtually mold-proof structure.Īs good as all this sounds, perhaps the best thing about SIPs construction appeals to us builders. ![]() Wall and roof structures made from these panels have better energy performance than stick frames because the foam insulation layer is continuous. The second SIPs advantage is performance. carpenter with a fully-loaded tool belt barely makes the thing flex. You can take a 10-foot long length of SIPs measuring just 6 1/2-inches x 8 inches in cross section, set it across blocks at each end and walk across the thing like a bridge. Engineering studies show that a SIPs wall is three times as strong as an equivalent stick-framed assembly, but it wasn’t until I tried some experiments for myself that I became completely convinced. Five or six inches of foam between two layers of 7/16-inch OSB sounds pretty flimsy, but glue them together into a panel and three surprising things happen. SIPs are a factory-laminated sandwich of foam and oriented strand board (OSB) that replaces traditional wall and roof framing in residential and light commercial projects. Here’s a quick look at what SIPs are and how to build with them. The building technology I used for walls and roof is generically known as structural insulated panels (SIPs), and it greatly improves the quality, durability and energy performance of Canadian homes. Experiences like this, and some surprising scientific data I’ve discovered, convinced me to make foam the main part of my latest building project, a two-story, 24-foot x 28-foot woodworking shop with an office loft above. In fact, foam is so effective at preventing energy transfer that it even feels like the stuff is heated when you hold it without mitts on a cold day. IMPORTANT! Any design changes after this point will require that a change order be signed to reflect the new scope of work and additional charges may be incurred.If you’ve ever picked up a piece of rigid foam sheet with your bare hands in winter, you know what a great insulation material it is. ![]() It’s critical to keep the process moving, any delay in approval of production drawings could mean a delay in your production slot at the factory.Our panel Engineer then prepares revised drawings (based on your corrections) and returns revised drawings to you for further review and approval.and make any corrections then return these corrections back to us You or your representative thoroughly review the drawings, verify the dimensions, placements, etc.Our panel Engineer prepares the first draft and forwards to you or your representative (contractor, architect, etc.) for review.The drafting process can take between 2-6 weeks, depending on the detail and quality of your drawings initially provided to us and depending upon the review timeline. Please note, after your written acceptance of the production drawings there will be an additional charge to change any production cuts. During this process of drafting and review you’ll need to inspect the drawings and make any changes you desire. After your acceptance of the Sales Agreement and receipt of your deposit, we’ll begin the drafting process that we include with your production drawings as mentioned above. ![]()
