The Firestone RubberCover System is based on EPDM roofing membranes that are made of a synthetic rubber compound. 

For more than 25 years Firestone EPDM membranes have been installed on commercial and industrial low slope roofs worldwide offering proven field performance. Now the high quality RubberCover is available for residential roofing applications.

Firestone Rubber roofing offers many benefits:

  • . Large seamless single-ply sheets
  • . Flame free applications
  • . Easy to install without special tools
  • . Little or no maintenance
  • . Life expectancy up to 50 years
  • . Lightweight, highly flexible and Eco friendly


It’s simple and easy to install. It utilises conservatory space more effectively since it leaves walls free from radiators. The backer board makes it cost effective to run, and you can save up to 70% on running costs by using insulation boards. 

Under floor heating delivers a near perfect temperature profile between floor and ceiling. Warmth generated by under floor heating is radiant heat where the floor evenly releases heat, which is absorbed by people and objects in the room. Under floor heating systems require less maintenance than conventional heating systems. Unlike radiators, under floor heating systems do not have individual valves in each room, which are prone to fail from time to time.
