Boulder SFTV SuperFOIL Thermal & Vapour Barrier (90R)

SuperFOIL SFTV all-round building membrane for roofs, walls and floors. Water & vapour proof SFTV is also a foil radiant barrier that will reduce solar gain in summer and improve insulation in winter. SFTV’s reflective properties add to the overall U-value of the building fabric. To achieve the maximum energy performance in new build and retrofit projects, SFTV makes an ideal ‘airtight’ layer suitable for the entire building envelope.

SFTV Key Features:

• SFTV is waterproof and resists the passage of moisture through walls, floors and ceilings.
• SFTV improves the general airtightness of the building.
• SFTV is a radiant barrier and can be used to enhance U-values in both new build and renovation projects.
• SFTV is vapour proof and restricts the passage of warm moist air from within the building from permeating into the structure or the roof.
• SFTV is suitable for roof and wall applications.
• SFTV has a vapour resistance greater than 200 MNSG.
• SFTV has a permeability rating less than 1.0.
• SFTV helps to prevent mould and damp staining.
