MonarTile Supa 1F

Reinforced bitumen undertile lining featuring elastomeric bitumen and a lightweight and super strong synthetic polypropylene material within a composite construction. The membrane is designed for use in ventilated warm and cold pitched roof situations and is especially used for hard boarded roofs ofeither roof grade plywood, OSB boards or timber sarking.

It is manufactured using a super strong polypropylene nonwoven reinforcing carrier which is saturated and then coated in SBS-modified bitumen. The membrane is surfaced with silica sand on both sides to prevent the felt sticking in the roll. Combines excellent tensile strength characteristics with high puncture and nail tear resistance. It is also are resistant to UV light degradation, but is not designed to be left exposed for long periods and must be covered as soon as possible.
