Klober Sepa Solar is an air barrier and vapour control layer for use on the warm side of the insulation. Designed with a reflective surface for enhanced thermal performance, reducing heat loss through the roof.

Benefits

Prevents large amounts of water vapour entering the construction from the inside
Silver reflective surface increases thermal resistanc and therefore reduces heat loss
With 500 MNsg vapour resistance it exceeds BS9250 requirements

Technical Data

Colour - Reflective

Fire Rating - F

Installation

Before Sepa Solar is installed, check the moisture content of the timbers is less than 20%. Fix on the warm side of the installation and rafters with the printed smoother surface facing inwards
At either edge of the structure, leave a 150mm overlap to allow Wallint 50 to be sealed to adjoining walls
Roll-out with a horizontal headlap of 150mm. Fix to rafters/ceiling joists using non-corrosive fixings eg staples. Ensurelaps are sealed using a tape such as Permo TR
Where pipes pass through use a Klober Pipe Sealing Collar and tape edges to Wallint 50 to achieve an airtight seal
Sepa Solar should cover the entire internal timber frame area of the rooms in the roof and, where applicable, link with vapourcontrol layer in the wall below to form a continuous air barrier
