Compression Grade Rigid Foam Insulation Panels

It is comprised of an extruded polystyrene closed cell foam panel with continuous skin.

Compression grade rigid foam insulation panels.

Kingspan insulation r 4 common. Tape the seams of the foam panels with heavy duty construction tape. Be sure to use compression grade rigid foam panels which are designed for installation beneath concrete slabs. Check with your supplier or the manufacturer for advice on the best thickness and r value to use.

Rigid foam insulation is a more effective air barrier than batts or blown in insulation especially if the seams between sheets are carefully sealed with caulk canned spray foam or tape. Eps is a closed cell lightweight and resilient foamed plastic composed of hydrogen and carbon atoms. The mechanical strength of eps varies with its density. The r value for foamular xps insulation is provided from testing at two mean temperatures 40ºf and 75ºf and from two aging conditioning techniques 180 day real.

The time of testing. Rigid insulation is one of the best tools to reduce your energy costs. Rigid foam insulation also known as insulating boards provide high r values. 0 75 in x 4 ft x 8 ft.

Because rigid foam plastic insulation products are not all aged in accordance with the same standards it is useful to publish comparison r value data. The compressive behaviour test also known as the short term test involves increasing a load at a constant rate of compression until the material s compressive strength or compressive stress at 10 relative deformation is determined. Rigid foam is routinely used to insulate the interior or exterior of foundation walls. Leave a 1 4 inch gap around the perimeter.

Use a utility knife to cut the foam to size a hacksaw or drywall saw also work well for this. You can even place it under the foundation slab. 0 75 in x 4 ft x 8 ft 1 unfaced polystyrene foam board insulation item 304087 model 100000050511. They keep your home at a comfortable temperature without the need to crank your heat.

You might be wondering why some materials yield before 10 strain and others don t. Insulfoam eg meets or exceeds the requirements of astm c578 standard specification for rigid cellular polystyrene insulation. Eps has a compressive resistance between 10 60 psi for most construction applications. The most important mechanical property of eps insulation and building products is its resistance to compressive stresses which increase as the density becomes higher.

Insulfoam exterior grade eg insulfoam eg exterior grade insulation is a versatile product consisting of a superior closed cell lightweight and resilient expanded polystyrene eps.
