A reflective, high-resistance air and vapour control layer for internal walls, ceilings and floors.
Application
For internal walls, ceilings and floors.
Description
Reflectatherm Plus is a reflective, high-resistance air and vapour control layer for internal walls, ceilings and floors. It is specifically designed to enhance the thermal performance when placed on the warm side of the insulation.
The membrane should be installed with the foil side facing the cavity. In ceilings, the product is placed between the underside of the rafters and the ceiling lining. Adjacent sheets should be lapped by at least 150 mm and sealed with a suitable tape. Minimise penetrations caused by services and seal all joints.
Features and benefits:
- R-value of 0.665 m2K/W when used with a minimum 19 mm service cavity.
- High vapour resistance.
- Improved airtightness.
- Creates service void.
- Creates an unbroken vapour control layer.
- Sd Value of >150 m.
- Help meets the requirements of Part L in England and Wales, Section 6 in Scotland, and Technical Guidance Document L in Ireland.
