Daltex® RoofTX® Optima 

Daltex® RoofTX® Optima is a 3-layer low resistance vapour permeable air barrier roofing underlay for pitched roof construction. Daltex® RoofTX® Ultra is also certified for use in walling.

Daltex® RoofTX® Optima is suitable for fully supported or unsupported applications and can be utilised in conventional ventilated roof constructions.

accordance with the relevant Agrément Certificate.
