This membrane is used on both wall and floors with an "air gap" of 5.3 Litres of space per m2. This membrane is used for light water ingress situations, and is also available in a clear version for walls. This aids the selection of good fixing points in the more difficult application i.e. Random stone and friable brickwork.

The sealed DELTA fixing is used to secure System 500, the centre shank of this fixing is also used for subsequent dry lining applications, using a size 12 screw.
