A blanket of insulation that wraps your home

Mastic Structure® EPS insulated siding adds a continuous blanket of insulation to the outside of your home. Mastic siding improves energy efficiency, reduces outside noise, and makes your home more comfortable year-round.

Each Mastic siding panel offers an increase in R-value for the wall system. R-value means resistance to heat flow. The higher the R-value the greater the insulating power.

More Impact Resistance than Standard Vinyl Siding

Advanced engineering and design systems deliver superior strength and rigidity for a longer product life cycle. In actual testing, a Mastic siding panel withstood hammer blows that damaged lesser siding products.
