The roof area can be the area of highest heat loss in buildings. In order to conserve energy and to make buildings more comfortable, building codes stipulate higher thermal resistances (R-values) for the roof area compared to other building components.

Plasti-Fab’s EPS insulation is an excellent choice for roofing applications due to its long-term thermal resistance and performance qualities. With R-values ranging between 3.75 per inch to 4.7 per inch depending on the product used, it is a cost-effective thermal insulation that provides increased energy efficiency within the structure.

On traditional cathedral ceilings where tongue and groove timber exposed on the inside is used as an architectural feature, PlastiSpan insulation board is ideal for both single and double layered applications.
