2020年7月29日 · The importance of slab-edge insulation at first seems counterintuitive, but the images from Therm offer vivid confirmation of the transfer of heat under extreme conditions. It is important to understand that the impact of slab-edge insulation decreases with depth and insulating the upper portion that is exposed to outside air is the most critical.

Installing rigid foam around the perimeter of a foundation can be time consuming. One way to speed the process is with a product called Energy Edge. PVC concrete form protects foam insulation. Energy edge is a PVC form with integral 2 in. expanded polystyrene (EPS) foam board (R-8). It forms and insulates the slab while protecting the insulation.

2016年6月18日 · Question about slab insulation. The current slab has zero insulation on each side. That was no issue until now because it always an unheated garage. The slab is just that, a slab. No footing, no drainage. Living in zone 5A and using the table Martin gave me in another thread I conclude I need: - R-10 on the edge. --> 2.38" EPS or XPS* - R-30 on top of the floor …

2021年8月6日 · An insulated raft slab resembles a frost-protected shallow foundation, with two main differences: an insulated raft slab usually has a uniform thickness rather than a thickened edge, and an insulated raft slab always includes a continuous layer of horizontal insulation under the entire slab. Slab basics

2010年6月5日 · Insulating both the slab edge and the exterior of the frost wall a foot or two down will improve thermal performance. After that, the most important place to insulate a slab-on-grade is the outer 4' of the interface between slab and ground (sub-slab). Of course, always use a vapor/radon barrier and install a radon vent under the slab.

2017年12月15日 · The second of these two articles notes that the Building Science Corporation recommends the use of R-7.5 slab edge insulation in Climate Zone 3. If you are talking about a basement slab, you probably don't need any slab insulation in Climate Zone 3.

2023年11月9日 · They’ll be 24″ to 56″ above grade. Inside will be 250 yards of compacted AB, then 2″ of XPS, 2′ around the perimeter (considering 4′), then 10 mil poly, then the slab. I’m struggling with the slab edge and stem wall insulation in AZ where termites are a concern.

2023年6月21日 · In reading through the 2018 IECC (R402.1.2) for climate zone 5 the column for SLAB R-Value and Depth shows R10, 2 ft depth (table atch’d). Note “d”says: “R-5 insulation shall be provided under the full slab area of a heated [edit] slab in addition to the required slab edge insulation R-value for slabs. as indicated in the table.

2021年2月24日 · BEOpt doesn’t have a way to add “insulation” to the top of the slab so I used the Foundation Floors>Carpet input which allows you to specify the R-value of the carpet pad. In the attached graph: Point 1 is an uninsulated slab Point 2 is 100% top of slab R-10 insulation Point 3 is 100% top of slab R-20 insulation

2024年3月31日 · Also, your slab edge is INSIDE your wall. It's not an exposed slab edge. So it's protected by the insulation of your SIP. At that point, the bottom of your panel, it's up against lumber rather than insulation. But framing lumber itself has an …
