Lineflex Fleece Backed EPDM
Lineflex is a heavy duty fleece backed EPDM roofing system ideal for residential, commercial and industrial buildings.
Lineflex Fleece Backed EPDM comprises an EPDM membrane that is laminated to a tough polyester reinforcement layer which greatly increases its durability as well as improving its tear and puncture resistance.
