Compression Grade Rigid Foam Insulation Panels

Rigid foam is routinely used to insulate the interior or exterior of foundation walls.

Compression grade rigid foam insulation panels.

You might be wondering why some materials yield before 10 strain and others don t. The most important mechanical property of eps insulation and building products is its resistance to compressive stresses which increase as the density becomes higher. 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. Install it anywhere from the roof to the foundation.

Extruded polystyrene xps rigid foam insulation owens corning foamular 250 extruded polystyrene xps rigid foam insulation is a closed cell highly moisture resistant rigid foam board well suited to meet the needs for a wide variety of residential and commercial construction applications. The mechanical strength of eps varies with its density. The time of testing. 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.

Eps has a compressive resistance between 10 60 psi for most construction applications. 0 75 in x 4 ft x 8 ft 1 unfaced polystyrene foam board insulation item 304087 model 100000050511. Be sure to use compression grade rigid foam panels which are designed for installation beneath concrete slabs. Insulfoam eg meets or exceeds the requirements of astm c578 standard specification for rigid cellular polystyrene insulation.

Use a utility knife to cut the foam to size a hacksaw or drywall saw also work well for this. Eps is a closed cell lightweight and resilient foamed plastic composed of hydrogen and carbon atoms. 0 75 in x 4 ft x 8 ft. 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.

It is comprised of an extruded polystyrene closed cell foam panel with continuous skin. Rigid foam insulation also known as insulating boards provide high r values. Leave a 1 4 inch gap around the perimeter. You can even place it under the foundation slab.

They keep your home at a comfortable temperature without the need to crank your heat. High compressive strength rigid foam insulation description owens corning foamular 400 600 1000 extruded polystyrene insulation is a high density insulation designed for use in engineered applications requiring additional load bearing capability. 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. Kingspan insulation r 4 common.

Rigid insulation is one of the best tools to reduce your energy costs.
