About EPS - Expanded polystyrene (EPS) has proven to be the most cost-effective panel core insulation material available. EPS has the highest R-value per dollar invested. Its R-value per inch is much higher than fiberglass or cellulose insulations. "R" means resistance to heat flow. The higher the R-value, the greater the insulating power. EPS is also physically stable, unlike fiberglass or cellulose, which tend to settle with time, creating voids and many thermal breaks. Unlike most insulation products he R-value of EPS increases as the temperature drops. EPS is an inert, organic, recyclable material. It contains no CFC's, HCFC's, or HFC's, will not rot, is resistant to mildew, and provides no
food value to animals (including rodents).

About OSB - Oriented strand board (OSB), first developed in the 1980's, is a wood panel that has been "engineered to perform" for housing and construction. OSB is not chipboard, flakeboard, particleboard, or aspenite. It has been specifically designed to be the most dependable, versatile, and environmentally efficient wood panel on the market today. OSB uses only freshly harvested trees from sustainable fast growing forests or tree farms. The trees are processed into precisestrands averaging 4 inches long and 1 inch wide. The strands are oriented length-wise on the exterior and cross-aligned on the interior. The alternating layers are then bonded with resins under high heat and pressure. The resulting product is very strong and uniform and shares many of the same properties as plywood. Because of its great versatility and performance, we have chosen OSB in all areas of our homes where strength,stiffness, and durability are required.

Roof Sheathing Uniformly sound and extra rigid, OSB roof sheathing handles snow and wind loads with ease.

Sub floor OSB Tongue and Groovesub floor sheeting providesa strong rigid and
impact resistant platform for underlayment, carpet, tiles, or whatever type of
flooring you install.
