MODERN TORCH-ON MEMBRANES

SBS modified bitumen technology has proven by far to be the most reliable technology in the waterproofing industry. Most SOPREMA roof waterproofing membranes are made with SBS modified bitumen and include a reinforcement of non-woven polyester or glass mat. Developed by our research and development team, their unique formulation and superior quality provide exceptional durability and resistance to severe weather conditions.

Sopralene® elastomeric waterproofing comprises a comprehensive range of torch-on heat-activated membranes comprising two principal components:

Expertly blended SBS elastomeric bitumen
High resistance polyester reinforcement

For example Sopralene® is used for roof and general waterproofing, including basement walls, in both new and refurbishment projects.

THE COMPONENTS OF SOPRALENE® SYSTEMS

Sopralene torch-on waterproofing systems include the following components:

Primer – required for OSB, timber, concrete and asphalt substrates, as well as the crowns of metal decking
Vapour control layer – essential for insulated warmroofs, the type dependent onthe warranty period required and the humidity level inthe accommodation below the roof
Thermal insulation – the insulation boards used for warm roofs should be of polyisocyanurate (PIR) and for protected/inverted roofs, extruded polystyrene
Venting base layer – a perforated membrane which allows partial bonding of the underlay to the primed deck or insulation layer below
Venting underlay – a layer that combines the functions of a venting layer and an underlay
Underlay – an intermediate layer designed to receive the final capsheet
Capsheet – the final layer with a granular surface finish to receive pedestrian traffic or further finishing layers, eg, inverted roof insulation and ballast
