Mastic Asphalt Flat Roof

We manufacture a PIR thermal insulation board that is ideally suited to mastic asphalt waterproofing systems.

Across new build or refurbishment constructions, mastic asphalt can be an ideal choice for roofing systems that require a smooth and seamless, high performing surface finish. The product comprises of suitably graded limestone aggregates bound together with an asphaltic cement (primarily refined bitumens) to produce a dense voidless material, offering total waterproofing integrity.

Our products can benefit the inherent strength and durability of this system even further, and are available in a wide range of thicknesses to complement all requirements. Just one of the benefits is the board's high compressive strength, resulting in insulation that is suitable for loads associated with sustained pedestrain maintenance traffic.

Our Powerdeck F is the ideal board for mastic asphalt applications.
