“EPS - The Safe Insulation”

Stacks Image 4482

Roofing With EPS Insulation Has Many Advantages
Best Insulation Value
Expanded Polystyrene (EPS) rigid insulation is the most cost effective and by far the best value for roofing insulation. EPS is clearly the lowest cost, R-value per board foot, both in flat and tapered roofing insulation boards. (See Graphs) Using EPS and reducing the cost of a roofing system can help a contractor win more jobs. EPS is a great way to beat the competition and offer the best value to the building owner.

EPS Offers Lowest Cost Per “R”
No Themal Drift
Expanded Polystyrene (EPS) is manufactured in a way where 98% of the product is enclosed in small chamber filled up with regular air. Other types of insulations use diffusive gasses to help increase their R-values. These gasses tend to escape out eventually lower their R-Value. In EPS air can be replaced with air and it has no effect on the R-Value. That is whys in numerous lab experiments and studies, EPS R-Value tends to remain constant. Learn More

The
Long-Term Thermal Resistance (LTTR) method of measuring insulation R-value uses a 15 year weighted average, however most buildings have a lifespan of 100 years.
Enviromentally Friendly
EPS is environmentally friendly in so many ways. EPS consist of 98% air and the 2% that remains is derived from a by-product of oil refining. By-products that could become waste, but have found there way into a productive product that saves energy. In fact, EPS insulation can return up to 200 times the amount of energy required to produce it, and reduce emissions by up to 100 times the volume produced during the manufacturing process. EPS is one of those product that can be used and recycled over and over again. Learn More
