DELTA®-VENT N PLUS/ DELTA®-VENT
DELTA®-VENT N PLUS/DELTA®-VENT N is a 3-ply sheet, which makes it particularly resistant to mechanical loads during installation. Moreover, its matte surface prevents irritating dazzle effects. The high vapour permeability of DELTA®-VENT N PLUS/DELTA®-VENT N ensures that residual moisture rising from inside is dried out safely. On the outside, the sarking sheet reliably protects the heat insulation from driving snow and rain. This ensures that the insulation remains dry and functional outside. DELTA®-VENT N PLUS/DELTA®-VENT N consists of a tear-resistant and breathable of PP spunbond and foil combination. DELTA®-VENT N PLUS/DELTA®-VENT N is equipped with an adhesive zone along both edges which ensures excellent adhesion without any need to arrange a highly precise overlap. The sheet is also available without integrated adhesive strips under the name of DELTA®-VENT N.
