Wallint 50

Product Code: KU0065

Prevents large volumes of water vapour entering from the interior, particularly during the drying out period.

Can be used in conjunction with other Klober products that reduce the loss of energy by offering water tightness.

Provides support for insulation boards or quilts.

Product Description

Wallint 50 is a combined air barrier and vapour control layer. It has a vapour resistance of 250MNsg, meeting the requirements of BS9250 (Code of Practice for design of the airtightness of ceilings in pitched roofs). Building regulations demand thicker layers of insulation, therefore it is becoming increasingly important to provide an air barrier and vapour control layer on the warm side of the insulation. Wallint 50 has been especially developed to target this requirement.

Area of application

The inner face of an insulated roof, wall or ceiling, including timber frame.

Suitable for cold and warm roofs.

Installation Tips

Before Wallint 50 is installed, check the moisture content of the timbers is less than 20%. Fixed 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.Fixto 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.

Wallint 50 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
