Monofilament 250 is designed for use in buildings with low to medium humidity.

Monofilament 250 is constructed using a three layered membrane combination and incorporates a high density polyethylene reinforcement grid, which ensures high tensile strength and excellent water vapour resistance.

Monobond LT double sided tape should be used for all joints and penetrations.
