ThermaMembrane FR – insulation sandwich panel PU

Thermoinsulation and Waterproofing in one

ThermaMembrane FR


ThermaMembrane FR is the most recent, breakthrough technology in flat roof insulation systems. With the use of “2 in 1″ method (integrating waterproofing and thermoinsulation functions) it utilizes panels made with PU foam that are factory-covered with a waterproof layer which is produced with specialized roof membrane. Highly simplified single-layer setup allows to cut assembly time by 50% in comparison with multi-layer systems. Combination of hydro- and thermoinsulation layers prevents the formation of empty gaps which greatly improves performance and durability of the setup. Attachment of panels to the concrete or steel (trapezoidal sheet) base occurs with the use of telescopic systems. Panel’s joints are weld with flexures of roof membrane. The full set of assembly accesories is available.


Very good thermoinsulation parameters. Large range of available thickness variants (100, 125, 140, 175 mm). Single-layer setup of waterproofing (roof membrane 1,2 mm as front facing of the panels). Compressive strength 120 kPa (at 10% strain). Reaction to fire  B-s3, d0. In FR (Fire Resistant) version, the product has fire resistancy REI 30. classification. Fire resistancy to external fire BROOF (t1). Panels are by default available in 1000 x 2400 mm (width x length) format. On an individual request there is a possibility to optimalize lengths of the panels to the dimensions of the roof (by reducing the number of transverse connections). Excellent resistance to variable temperatures and UV radiation. Compliance with standard: PN-EN 13165:2010.
