PHS Airtight Liquid Membrane is a VOC-free solution designed for ensuring airtight and vapour-tight construction junctions in both new builds and retrofits. Available in 5Kg and 10Kg tubs, this water-based liquid membrane is a sustainable option that offers an uninterrupted seal around penetrations, cracks, gaps, and the contours of various substrates.
Perfect for Passive House Systems, this brush-applied liquid membrane provides durable airtightness and adhesion, creating a seamless barrier against air and vapour infiltration. The fibre-reinforced polymer formulation ensures exceptional durability and flexibility, making it ideal for all airtight connections, including roof connections, ventilation systems, and around EPDM.
Key Features:
- Airtight Membrane: Made with a unique and sustainable solution for airtight construction junctions in both new builds and retrofits.Ensures a seamless and continuous airtight and vapourtight seal.
- Brush Applied: The liquid membrane is brush applied for ease of use. The 10Kg container is ideal for spray painting
- Seamless Seal: Creates a seamless and continuous airtight and vapourtight seal over cracks and gaps. Fiber reinforced therefore suitable for crack bridging up to 2mm.
- Versatile: Suitable for use on a wide variety of building materials. It is ideal for both new builds and retrofits, enhancing energy efficiency. Furthermore, this liquid membrane can be painted, plastered or taped after drying.
- Drying Time: Indicative drying time of 24-48 hours, depending on local conditions such as air humidity and applied layer thickness.
- Energy Efficiency: Helps increase energy efficiency within the building, contributing to lower energy consumption. It stays elastic after curing and very sustainable
