Protan Ballasted Roofs

Covered water pressure membranes in roof structures are generally referred to as protected roofs. The ballast material may be concrete slabs, shingle, or soil as the surface for a planted roof.

Protan Inverted Roofing Systems

Inverted roofs are an insulated, ballasted roof structure with the membrane under the insulation.

Protan Dual Roofing Systems

Dual solutions have insulation both over and under the membrane. The membrane is provided with extra protection against temperatures and mechanical loading from both sides.

Protan Green Roofs
