b) Slab on grade at foundation wall with interior insulation down 1.2 m, or to the footing with a thermal break at the slab. It is a cost effective and efficient insulated under-slab ventilation system. The designer suggested 2" rigid fo It can also be installed beneath outdoor terraces, sidewalks and parking lots to accelerate the melting of ice and snow. The use of under-slab insulation listed in CSA B214 Installation Code for Hydronic Heating Systems includes a minimum RSI 0.88 (R-5) insulation beneath a heated slab. on each level, located near Ottawa, Canada.The slab on grade will have hydronic radiant heating. DuroFoam is the solution to your insulation needs. COMFORTBOARD™ 80 is an exterior non-structural insulation sheathing that provides a continuous layer of insulation around the commercial or residential building envelope. c) Slab on grade at foundation wall, with insulation in a 1.2 m perimeter under the slab with a thermal break. Exterior Concrete Slab Insulation Options It is good practice to insulate concrete slabs in cold climates to protect the slab from frost penetration. Additional insulation is applied along the edges of the slab, because that is a primary surface for heat loss. This highly effective combination of materials offers high compressive strength and great thermal performance when used in below grade and under slab … SilveRboard is a rigid insulation board made from Expanded Polystyrene (EPS) covered with a layer of polypropylene reflective lamination on both sides. With multiple roll sizes and patented technology, Insul-Tarp is a step ahead of other rolled insulation products on the market today. Lack of foundation insulation on below-grade and under slab projects can account for up to 25% of a structure’s total heat loss. The benefits of under-slab spray foam insulation: 1. The Barrier under concrete insulation is a thermal block which insulates the concrete from the cold and dampness of the ground. Heat flows from hot to cold, and in the […] ROCKWOOL, 8024 Esquesing Line, Milton, Ontario, Canada L9T 6W3 T: 1 800 265 6878 E: contactus@ROCKWOOL.com www.ROCKWOOL.com 1 of 2 Issued: 01/25/2017 Re: Technical Bulletin – ROCKWOOL Under Slab Insulation It is easy to install and can be used in many applications; exterior sheathing, interior basement walls, exterior foundation, hydronic and under slab insulation. ... High Density (HD) Foam Insulation Below grade/ Under slab solutions. 2. This compliance option is explained this way: “Insulation located below grade shall be extended the distance provided in Table N1102.1.1 [namely, 2 ft. in climates zones 4 and 5, and 4 ft. in climate zones 6, 7, and 8] by any combination of vertical insulation, insulation extending under the slab, or insulation extending out from the building.” Radon Guard will soon be readily available at most building suppliers, is competitively priced, and is fast, clean and easy to install. Slab-on-grade comes with a few green benefits — which I love. Adding a continuous layer of insulation under the concrete slab foundation creates a thermal barrier between the ground and the heat-conductive concrete. Figure 4 . EcoFoil Under Slab Insulation is superior to traditional, outdated forms of concrete floor insulation such as polystyrene or foam sheets. As far as termites go- it's cracks more than the insulation under the slab that'll cause you problems- if the termites can't get to it, and if it's dry, they aren't going to go there. A resource to point them to for example calculations is the article “Right-sizing Under-slab Insulation,” in the April 2014 issue of Structure magazine. The standard for acceptance for under slab insulation is Type 2, 3 or 4 EPS or XPS as per the table below.
