Description

Klober Wallint 50 Air Barrier & Vapour Control Layer 50m x 1.5m

Klober Wallint 50 is a combined air barrier and vapour control layer, with a vapour resistance of 250MNsg, meeting the requirements of BS9250 (Code of Practice for design of the airtightness of ceilings in pitched roofs).

As even thicker layers of insulation are installed to comply with more demanding Building Regulations, so it becomes increasingly important to provide an air barrier and vapour control layer on the warm side of the insulation - Klober Wallint 50 has been especially developed for this purpose.

Technical

  • Roll size: 50m x 1.5m = 75m2
  • Roll weight: 9.5kg
  • Material: Composite PP spun fleece with coating

Features

  • Prevents large volumes of water vapour entering a construction from the interior, particularly during the drying out period
  • Provides support for insulation boards or quilts

Fixing

  • Before Wallint 50 is installed, check the moisture content of the timbers is less than 20%.
  • Fix on the warm side of the insulation 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.
  • Ensure laps are sealed using Permo TR tape (available separately).
  • Ensure that Wallint 50 is sealed at all abutments/junctions using Permo TR tape.
  • If parging, first turn Wallint 50 down the face of the wall, fix plaster stop bead on top of Wallint 50 and then parge on top.
  • Any holes or tears in the air barrier / vapour control layer should be repaired with Permo TR tape.
  • Klober Wallint 50 should cover the entire internal timber frame area of the rooms in the roof and, where applicable, link with vapour control layer in the wall below to form a continuous air barrier.
  • For refurbishment projects, Wallint 50 should be laid vertically either from ridge to eaves or vice versa. This is to allow small sections of the roof to be worked on.
  • Joins should be taped and sealed at the eaves using Permo TR tape (available separately).
