PHS Hi-Thermia reflective membrane is a very durable and robust vapour control layer (VCL), applied internally. It’s metallised surface reflects up to 97% radiant heat back into the building which enhances thermal performance. It has a very low emissivity and a high vapour resistance, so when installed continuously with all laps and penetrations sealed it provides efficient condensation control in all building types.
Applications:
- Interior installation to create an airtight envelope.
- All construction types.
- Warm and cold pitched roof.
- Ceilings, walls, suspended floors and loft spaces.
Features & Benefits:
- High vapour resistance of 750MNs/g.
- Improves airtightness and thermal performance.
- R value of 0.79m²K/W when used with a minimum 19mm service cavity.
- Meets Building Regulations Part L.
- Increases building energy effciency.
