  • 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

  • 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
