Composite Product description
Composite board insulation is usually is made of two different insulation materials that are laminated together. Mainly used for low – slope roofing, a typical example of a composite board is PIR or EPS combined with perlite or wood fiberboard. Composites also can incorporate insulation with other roofing materials, such as PIR laminated to a nailable substrate such as oriented strandboard.
The advantage of using a composite board is that it combines the benefits of two different materials in one board. Composites generally are compatible with bitumens and are impact-resistant. The fire, moisture, and thermal resistance can vary depending on the materials used.4
