There are a number of different factors at play but the one thing that we always need to keep in mind is heat flow. DuroFoam insulation is a closed cell and moisture resistant insulation with a white film on one side and silver on the other. COMFORTBOARD™ 80 is an exterior non-structural insulation sheathing that provides a continuous layer of insulation around the commercial or residential building envelope. 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.” 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. The warm air will escape your home through its foundation resulting in a vicious cycle of heat loss and high energy bills. Given that the under-slab is the bottom part of the “box”, you should take care of insulating it otherwise there will be a deficiency in your slab or basement. on each level, located near Ottawa, Canada.The slab on grade will have hydronic radiant heating. It is easy to install and can be used in many applications; exterior sheathing, interior basement walls, exterior foundation, hydronic and under slab insulation. Permitted placement of insulation for unheated floors and slab on grade assemblies is shown below. Alberta will be fully under 9.36 including climatic zoning separation, by May 1st, 2016. Underslab Floor Insulation. InsulationStop is the best source for top-quality products at the best price. The Barrier under concrete insulation is a thermal block which insulates the concrete from the cold and dampness of the ground. Insul-Tarp® is a concrete slab insulation/vapor barrier designed to provide a thermal break and moisture barrier between the slab and grade. Adding a continuous layer of insulation under the concrete slab foundation creates a thermal barrier between the ground and the heat-conductive concrete. Fully Insulated Slab: Continuous insulation extends downward from the top of the slab and along the entire perimeter and completely covers the entire area under the slab.

Climate Zone 4: Lower Mainland and Southern Vancouver Island 11 Exterior insulation to the footing and insulation under all Lack of foundation insulation on below-grade and under slab projects can account for up to 25% of a structure’s total heat loss. To determine which below-grade rigid foam insulation is best to use, it is important to first understand the material’s makeup. Heat flows from hot to cold, and in the […] 2. No basement.The question is how much insulation to put under the slab? Need Insulation for Under Concrete Slabs & Slabs With Radiant Heat? Under slabs account for up to 25 per cent of a building’s total energy loss. ROCKWOOL COMFORTBOARD™ 80 is a rigid mineral wool insulation sheathing board that is non-combustible, water-repellent, fire-resistant and sound absorbent. Vertical Insulation: Continuous insulation is applied directly to the slab exterior, extending downward from the top of the slab for the distance specified. The standard for acceptance for under slab insulation is Type 2, 3 or 4 EPS or XPS as per the table below. The benefits of under-slab spray foam insulation: 1. c) Slab on grade at foundation wall, with insulation in a 1.2 m perimeter under the slab with a thermal break. Additional insulation is applied along the edges of the slab, because that is a primary surface for heat loss. For comfort, and to save money, that's why! Below-Grade Under Slab system with FOAMULAR® Extruded Polystyrene rigid board insulation and radiant heating. Hi there,We design a 2 storey ICF house, 1800 sq.ft. Not all rigid insulation panels are alike. The research indicated installation of insulation beyond that of RSI 0.88 (R-5) provided negligible improvement in thermal performance of the slab. JavaScript seems to be disabled in your browser. ft. About the Product: The Reflectix® Concrete Slab Insulation is an innovative, easy-to-handle product that increases the energy efficiency of radiant floor and snow melt systems (under concrete). This enhances your overall building efficiency and prevents condensation and moisture buildup that can lead to structural damage. SilveRboard is a rigid insulation board made from Expanded Polystyrene (EPS) covered with a layer of polypropylene reflective lamination on both sides. Get all the construction documentation you'll need, in … It is a cost effective and efficient insulated under-slab ventilation system. Figure 4 .
