Sip meaning in construction12/8/2023 The crew have pre-assembled the boundary supports, so we don’t use more crane time and belch more diesel than necessary. On roof-day the crane arrives early, and the roof panels are rigged, swung up, and screwed in-place by Ted and Norm. The upper level walls take a day or so, and then it’s roof-day! We build the 2 nd floor-level TJI and sheeting floor system over the succeeding (2) days. On average we take about (2) days to assemble the 1 st floor SIP wall panels. Last week the TC Legend Homes crew finished off the SIPs roof structure on the Lake Stevens house. We aim to minimize L-splines as they have an insulating value of R7.8, compared to R29 for our Neopor graphite foam 6.5” Premiere SIPs wall panels. There a many cold-bridges in conventional framing and that’s why we don’t do it. A cold-bridge creates a poorly insulated pathway for the warm inside energy to travel to the cold exterior. Splines can be made of 2×6 lumber (L-spline), foam mini-SIPs (called S-splines), or an insulated TJI spline (called an I-spline).īecause a 2×6 lumber splines touches both the warm inside of the house wall, and the cold exterior of the house wall, they are said to cold-bridge. Two panels are joined by setting a ‘spline’ into the recessed gap on one panel, then sliding the second panel over the spline, nailing the connecting spline in place through all four edges. The SIPs panels typically have the interior foam held-back to form a 1.5” gap at the panel edges. How are SIP panels joined? We’ll use the walls as an example: The ‘S” in ‘SIP’ stands for structural and the panel-system carries the load of the house, floors and roof, and does not need the sticks of vertical lumber you see in the walls of a conventionally framed house. When you remember that there’s 4” foam under the concrete slab, the 6” foam walls and 10” foam roof trap all the heat inside the house. Our goal with SIPs panels is to create a continuous foam box, surrounding the inside of the home. We do use the crane to set to thicker, heavier roof panels. ![]() The doors and windows are cut-out in the factory, a stack of pre-fabricated house panels are loaded onto a trailer and arrives on-site where the SIPs are assembled… a bit like Legos.īecause TC Legend Builds affordable Net Zero energy houses, we use our crew to assemble the wall panels, man-handling them into place, but a crane can be used for walls. The sandwich-panels can be up to 24’x8’ and are made in the SIPs factory, in our case Premiere-SIPs in Puyallup. Actually, it’s not ply it’s OSB (oriented strand board). ![]() Fabricated from a slab of foam sandwiched between two plywood sheets. Internally they can be simply finished with plasterboard and a skim coating (with service cavities where needed) meaning that wet trades are kept to a minimum, speeding up build times even further.SIPs are wall, roof (and sometimes floor) panels. Equally they can be roofed with slates, tiles or metal roofing. SIPs are a very flexible product and can be used with any external cladding, be it brick, render, weatherboarding or metal cladding. With no need for cavity or internal insulation, structural insulated panels can provide a very fast way of constructing very efficient walls with u-values as low as 0.15, without additional insulation. The stressed skin layers make it exceptionally strong, whilst producing thinner overall wall thicknesses than other forms of construction. ![]() A Structural Insulated Panel (SIP) is made from a sandwich of two layers of stressed skin and one layer of insulation.
