due to its versatility, ease of installation and consistent performance benefits, enviroplus eps rigid foam-insulating sheathing is a standard way to insulate floors in homes and buildings. Sheathing creates an envelope around the slab of the structure that increases resistance to heat transfer and moisture penetration.
application of enviroplus eps in flooring
enviroplus eps sheathing is non-structural and is primarily used as an exterior insulator, both below and above grade, although it can be utilized throughout the structure in floors, roofs and ceilings. It is available in sheets measuring 2'x8', 4'x8' and 4'x9' ranging in thickness from ½ inch to 4 inches. Different densities help provide the r-value required to meet local building energy codes.
eps sheathing can be fastened with nails, screws, and/or staples depending upon the framing surface. Utilizing spot adhesive is the norm for masonry substrates. Be advised that some adhesives contain petroleum-based solvents that will dissolve eps on contact.
the joints of the sheathing should be close and flush. Seams are taped for added tightness and corner braces are installed to increase structural stability. Air-barrier house-wrap may not be needed if the sheathing is properly installed and seam tape is used.

benefits of enviroplus eps in flooring
the use of enviroplus eps rigid insulation has grown steadily over the last decade. While most building materials may fluctuate widely in price, the cost of eps has remained relatively consistent. This is especially appealing to contractors when bidding on a project. They don't have to worry about sacrificing profit margin due to an unexpected price increase for eps sheathing.
another benefit is the versatility of enviroplus eps. Manufacturers can provide the builder with insulation that varies in density. This translates into a structure that will meet or exceed energy code standards without the added expense of increased stud width. When higher r-value is required, rather than adding layers and layers of rigid insulation to meet the standards, eps is fabricated to a higher density.
eps has been used successfully for many years in areas where moisture is a concern, specifically below-grade. Fungus, bacteria or rot does not affect eps. The performance properties will not deteriorate when exposed to moisture and/or water.
