Application

Designed and developed for use in timber frame, light steel gauge, modular building and leisure building applications.

Delivers first line protection to the external of the building during construction against driving rain, and wind-blown snow providing ultimate protection to the interior of the building.

Description

Spunbond non-woven polypropylene construction membrane, designed and developed for use in timber frame, light steel gauge, modular building, and leisure building applications.

Delivers first line protection to the external of the building during construction against driving rain, and wind-blown snow providing ultimate protection to the interior of the building.

The high water vapour permeability provided ensures water vapour can pass through the structure safely into a vented cavity.

Features and benefits:

Effective condensation control and airtightness within walling construction.
Flexible and easy to install.
Greatly exceeds the requirements of the updated guidance in building regulations Approved Document Part L.
Meet and exceeds waterproofing requirements in BS EN 13589–2:2014 (W2).
Prevents water ingress to the structure.
Provides comprehensive waterproofing barrier to the sheathing during construction phase.
Can be combined with Envirotect AVCLs.
Reflective version also (Envirotect XT 150 Reflect wall membrane; specified separately).
