Compression Grade Rigid Foam Insulation Panels

Eps has a compressive resistance between 10 60 psi for most construction applications.

Compression grade rigid foam insulation panels.

Insulfoam eg meets or exceeds the requirements of astm c578 standard specification for rigid cellular polystyrene insulation. Kingspan insulation r 4 common. Rigid insulation is one of the best tools to reduce your energy costs. The mechanical strength of eps varies with its density.

They keep your home at a comfortable temperature without the need to crank your heat. 0 75 in x 4 ft x 8 ft 1 unfaced polystyrene foam board insulation item 304087 model 100000050511. Rigid foam insulation also known as insulating boards provide high r values. It is comprised of an extruded polystyrene closed cell foam panel with continuous skin.

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 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. Rigid foam is routinely used to insulate the interior or exterior of foundation walls. You can even place it under the foundation slab.

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. 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. Leave a 1 4 inch gap around the perimeter.

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. You might be wondering why some materials yield before 10 strain and others don t. 0 75 in x 4 ft x 8 ft. Be sure to use compression grade rigid foam panels which are designed for installation beneath concrete slabs.

The time of testing. Check with your supplier or the manufacturer for advice on the best thickness and r value to use. 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. 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.

Use a utility knife to cut the foam to size a hacksaw or drywall saw also work well for this.
