Description

A high performance vapour control layer for use in buildings with low to medium levels of humidity, including bathrooms, kitchens and laundry rooms. It is suitable for use on both new and refurbishment projects. It is produced from two layers of virgin low density polyethylene (LDPE), with a reinforcing grid of high density polyethylene (HDPE) built-in. The reinforcing grid gives Monofilament 250 exceptional strength and a very high tear and puncture resistance.

Joints should be sealed with Monobond LT Tape.
