Firestone RubberGard EPDM Roofing Systems can easily be combined with any type of photovoltaic system: Conventional mono- or poly-crystalline photovoltaic modules are installed onto a rack support system, held in place using ballast or anchored into the roof deck. Any rooftop penetrations are made watertight using the Firestone EPDM accessories. Thin films (e.g. UniSolar) can be adhered to the EPDM membrane using the Firestone QuickSeam Tape System. CIGS panels (Solyndra) are installed onto a RubberGard EPDM Roofing System coated with AcryliTop paint. In order to guarantee the long term performance and watertightness of the roof, Firestone puts forward the following roof design: Firestone proposes to use a 1.5 mm thick membrane with higher puncture resistance in order to avoid damage to the membrane because of traffic on the roof during the installation of the PV system and its maintenance. Firestone proposes the use of rigid insulation boards with high compressive strength or use of a high density cover board in order to avoid damage to and crushing of the insulation boards, due to lack of long term compressive strength and/or traffic on the roof during the installation and maintenance of the PV system. Firestone proposes to fully adhere the membrane onto a compatible support (e.g. PIR insulation or ISOGARD HD Cover Board) and to use Firestone insulation adhesive (or approved insulation plates and fasteners) to attach the insulation boards (requirement for a smooth and flat support in case of thin film laminates).
