Description
PHS Sd Variable Plus Membrane is a triple layer fabric, high performance membrane, made from non-woven PP fabric.
PHS Sd Variable Plus is a robust airtight membrane with a variable Sd value. It’s reinforced mesh material is designed to create an airtight barrier within the home. With variable diffusion resistance, this membrane can adapt diffusion rates depending on the environment. The membrane creates an airtight layer that dynamically adjusts based on the humidity of the environment, preventing condensation build up and moisture damage. PHS Sd Variable Plus is highly recommended for flat roof builds and retrofits.
- Robust & Flexible
- Highly Tear-Resistant
- Variable Diffusion Resistance
- Moisture Variable, Sd value 0.4-35m
- Suitable for Air-Injected Insulation & Insulation Mats
- Ideal for flat roofs, retrofits and floors
PHS SD Variable plus is ideally suited for any retrofit project. For any retrofit project, it’s always recommended to use a variable SD membrane . Variable SD membranes have a dynamic SD value that allows them to adapt their moisture control to the environment. They are needed to deal with historic moisture in the building envelope to prevent any issues popping up in the future. This makes PHS SD Variable plus the most suitable membrane for any retrofit project. As it’s scrim reinforced and very dynamic, this allows it to easily deal with historic moisture inside of any building.
