LaHouse Home & Landscape Resource Center
LaHouse is a showcase for best practices and code-plus construction. Its flood and wind resistance features meet or exceed the criteria of the Fortified for Safer Living program of the Institute for Business and Home Safety (IBHS). LaHouse showcases multiple solutions across a range of price-points, integrating durability with other goals of sustainability: resource efficient, healthy, practical and convenient.
Structural Insulated Panel System (SIPS)
Structural insulated panels combine structural framing and insulation into a single product. Rigid foam insulation is sandwiched between two structural panels, or skins. The skins, which are glued to the foam, most commonly are oriented strand board (OSB) but can be steel, plywood or cementing material. SIPs can be cut on site or ordered from the factory with precut window and door openings and channels through the foam core for wiring. With precut panels, installation time can be less than half that of stick framing, with little construction waste. SIPS have high strength characteristics and are used for walls (4” foam) and roof (8”foam).
Anchor bolts tie bottom plate to slab.
Hurricane plates and extra fasteners secure wall panels to bottom plates.
A very low-pitched roof acts like an airplane wing in high winds. Because the breezeway roof at LaHouse will experience high uplift forces, the front and rear beams are heavily reinforced and firmly anchored to the walls on each end. Anchoring in the SIPS wall required a pocket and steel plate. Rafters that run along the ICF and SIPS walls have strong ties into those walls.
