Description
A spunbond non-woven, polypropylene construction membrane with a high purity aluminium surface.
Features and benefits:
- Effective condensation control and airtightness within walling construction.
- Flexible and easy to install.
- High-purity aluminium surface for enhanced thermal performance (R-value: 0.79 m²K/W).
- 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).
- Preventing water ingress to the structure.
- Provides comprehensive waterproofing barrier to the sheathing during construction phase.
- UV and heat stable.
- Low emissivity surface.
- Designed and developed for use in timber frame, light steel gauge, modular, and leisure building applications.
- Delivers a robust approach to airtightness; enhancing the overall thermal performance of the building structure. This significantly reduces the risk of interstitial condensation in accordance with BS 520:2021 Management of Moisture in Buildings.
- Independently tested by BTTG; UKAS accredited.
