Soft furnishings. Carpet and rugs can add an insulating barrier between you and the cool air under your house in winter. Insulating a concrete slab. Thermal mass from a concrete slab can be effective in winter due to its ability to store heat during the day and release it later.

Concrete slab insulation blanket. Insulation is applied to houses with slab-on-grade foundations exactly as you would insulate the outside of a full basement (see Section 6.1, Insulating the basement from the outside). If the foundation is on frost-susceptible soils, install a layer of impermeable insulation horizontally in the soil at a slope ratio of 1:5 for at least 1 m (3 ft.). Insul-Tarp — Concrete Slab Insulation. Insul-Tarp® is a concrete slab insulation/vapor barrier designed to provide a thermal break and moisture barrier between the slab and grade. Insul-Tarp® reduces condensation, mold and degradation by controlling water vapor migration. Insul-Tarp® is a multilayer blanket insulation, manufactured using cross woven polyethylene, high density closed-cell. 7. Foil Faced Blanket Roofing blanket consists of a lightweight flexible bulk mineral insulation blanket faced on one side with reflective foil laminate. The blanket material is available in various R-values and thicknesses. The bright foil face is typically a single sided foil and the emissivity assumed to be 0.04. Blankets may also be faced with
GreenStuf Autex Soffit and Slab Liner ASL is manufactured from thermally bonded polyester with a fire compliant efoil laminate facing on one side. ApplicationsGreenStuf ASL has been designed as an acoustic and thermal lining for all types of Concrete Soffits and Slab Linings. Its high durability rating means it is guaranteed for up to 50 years and is also vermin and insect proof. Insulation is laid on the concrete and covered with a screed. There will be a damp-proof membrane under the insulation and possibly a second membrane on top, depending on the type of screed. In this scenario, a rigid foam insulation is usual, and as you’d want the same U value in the roof, we need the same thickness of insulation (180mm). For maximum thermal insulation performance, XPS insulation should be installed not only over flat areas, but also against slab edges and trenches before pouring concrete. FoamulaR has compressive strengths that range from 150 kPa to 650 kPa (though FM300 at 300kPa and FM350 at 350kPa are the most common) so the product can adapt to a broad.
Concrete floor insulation is the ultimate extra step in guaranteeing a warm building and cheaper heating bills.. Space Blanket Insulation Fireproof Insulation Foil Insulation. by a polythene 500g protection layer above the floor insulation to protect the insulation from corrosion caused by the concrete, followed by the concrete slab . GreenStuf ® Autex Soffit & Slab Liner (ASL) is designed as a thermal and acoustic lining for concrete soffits, slabs and car park ceilings. Key Features and Benefits: Independently tested & assessed achieving NZBC Fire Standards; Naturally resistant to insects and vermin; Safe to touch 100% polyester This has been overcome by the development of special blanket insulation products, made of balsam wool, glassfiber, or rock wool, specifically designed for the job of protecting exposed concrete. Liners are more frequently made of asphalt-saturated and coated heavy kraft paper and flanges are usually provided to facilitate fastening the blankets.
Electric concrete heating blankets provide the protective layer of insulation and an extra boost of heating power to keep your concrete between 65° and 85° F. Concrete blankets have 10x more surface contact than other blankets. They efficiently transfer heat down into your concrete while heavy-duty weather-proof insulation protects it from.

Concrete blankets have 10x more surface contact than other blankets. They efficiently transfer heat down into your concrete while heavy-duty weather-proof insulation protects it from. Slab edge insulation. Slab edge insulation is usually sufficient, as approximately 80% of the heat loss occurs through the edge. Install edge insulation before the slab is poured. Do not install insulation under concrete edge beams.
When plastic sheeting or curing blankets are placed atop a concrete slab, much of the blanket is in direct contact with the concrete but there are also wrinkles and air pockets where the plastic remains suspended just above the slab. Condensed water pools wherever the plastic touches the slab, but the concrete under the air pockets remains dry. They are going to pour a concrete slab in the middle of winter and they don't want the ground frozen. In a few days when they are going to pour, they will take up the blanket and put down some rigid foam-insulation. Then they are going to install radiant heating tubing and pour the concrete on top of the tubes. Concrete insulation – foam board & blanket Insulation is of crucial importance to a radiant heated slab with PEX. Without a thermal break between the slab and the ground, heat will sink into the ground under the slab, resulting in longer warm-up time, higher energy costs and overall poor performance of the system.
**System R-Value: tested in a concrete slab configuration consisting of a 4” Concrete Slab, ¾” Insul-Tarp Insulation (½” compressed), 2” Gravel and 1” Sand. The total slab configuration was approximately 8”. The information below shows the R-Value at a 75° mean temperature. Some form of insulation should be placed between the slab and the ground be fore the concrete is poured (Fig. 23). Insulation can be added to an existing structure by excavating around the edges of the foundation to a level below the frost line, and adding 2 inches of waterproof insulating material to the sides of the slab (Fig. 24). Prodex Total Under Concrete Insulation is ideal for concrete slabs, radiant floors and driveways. This slab insulation is 0.2 inch, (5mm) closed cell polyethylene foam covered on one side with reinforced foil facing. Prodex exhibits less than 9% compression in thickness when subjected to loads associated with standard concrete floor systems.
Insulation under slab products are provided with facings that are designed to be specific for individual under slab applications and are explained in more detail below. Under Slab insulation is a fundamental part of the building envelope to comply with the National Construction Code (NCC) section J for commercial buildings. Radiant Heat Panels – Concrete Insulation Foam Board & Foam Base Blanket Insulation. Radiant Heat Panel insulation is of crucial importance to a radiant heated slab with PEX. Without a thermal break between the slab and the ground, heat will sink into the ground under the slab, resulting in longer warm-up time, higher energy costs and overall. A well-insulated concrete slab will contribute to the building’s thermal envelope, save energy and help to reduce energy costs. Under slab insulation ClimaFoam XPS Board has high compressive strength and moisture resistance, which makes it ideal for installation under the concrete slab to prevent thermal loss through the ground.
