Protan SE-B prefabriccated sheets w/longitudinal secret strips is a roofing system where roof Membrane of Protan SE-B are welded together in larger units, ie sheets with underlying, longitudinal strips. For optimal mechanical attachment, the strips are factory welded to the underside of the fsheets at a predetermined individual distance. The distance of the strips can be varied based on how wind exposed the building is and the calculated need for fastening density. Protan SE-B prefabriccated sheets w/longitudinal secret strips are delivered primarily in standardized variants that will suit most projects. The membrane satisfies BASTA's requirements for the selection of raw materials.

Protan SE-B Prefabriccated sheets w/longitudinal secret strips are ideal for roofing on large roof surfaces without too many obstacles such as roof lights and different types of penetrations. The system is particularly favorable on roofs that are extra wind exposed, where otherwise with a standard overlap system it would have been necessary to install 1m wide sheets or even narrower. Large roof areas can be covered quickly with minimal welding work on the construction site itself using Protan prefabriccated sheets w/longitudinal secret strips. The sheets enable quick assembly as large units of the roof membrane are laid in one operation and this significantly reduces the welding work.

• Lowest CO2 footprint in the entire life cycle (cradle to grave)
• Documented long service life
• Weather-independent installation provides predictable and safe progress
