Superior thermal insulation
Thermano is a perfect insulating system for flat roofs of new and refurbished buildings. Thermano is also an excellent insulation system for green and ballast roofs.
The insulating panels can be installed on all load-bearing surfaces, including rafters, trapezoidal profile sheets and concrete slab floors.
SUPERIOR INSULATING PERFORMANCE
LOWER THICKNESS AND WEIGHT
EASY AND QUICK INSTALLATION
LOW WATER ABSORBABILITY
The panels are quick, easy and clean to install. Thermano is an excellent insulation system for trapezoid profile sheets or reinforced concrete slabs, and other load-bearing substructures of flat roofs. An added value is the compatibility with various vapour barrier films (PE film, aluminium foil and tar paper) and water barriers, including torch-welded membranes, which are sensitive to focused fire.
Installation on trapezoidal profile sheets or reinforced concrete slabs
The difference between the installation of Thermano on trapezoidal profile sheets and reinforced concrete floor slabs is the selection of specific screws. Metal sheets require dedicated metal sheet screws, whereas reinforced concrete structures require concrete screws.

Exposure to fire
Unlike other thermal insulating materials exposed to high temperatures (e.g. fire), the Thermano material does not dwindle, it forms a permanent and mechanically durable scorch which isolates the structure form destruction by flames.
The chief material used in the production of the Thermano panels is polyisocyanurate (PIR), secured on both sides with a gas-tight cladding, comprising several polymer layers and aluminium foil.
The structure of PIR, the material for the Thermano panels contains over 90% closed cells, filled with a very low thermal conductivity gas. This structure ensures extremely good strength parameters and an extremely low thermal conductivity coefficient of λ = 0.023 (W/mK).
Other advantages of the material include: low absorbability (<2%), complete resistance to VOC, and significant strength; when exposed to high temperatures, PIR does not dwindle, it forms a permanent and mechanically durable scorch. These superior characteristics have been appreciated by U.S. spacecraft design engineers, who were the first to use isocyanate-modified polyurethane (PIR) as a thermal insulating materials for the STS (Space Transportation System), more commonly known as the space shuttle.
Thermano panel structure
Outer component: gas-tight cladding
The high gas-tightness of the Thermano panels ensures stability of thermal insulating parameters (the ageing lambda) over long periods of time (which is 50 years by standard design), unlike other polyurethane-based materials without the cladding, i.e. spray-applied (in situ) materials.
Inner component: polyisocyanurate (PIR) core
The PIR core is formed by polymerization of its two main components, polyols and isocyanates, with an addition of modifiers. The PIR core is a closed cell structure, which means that the material is an essential barrier to capillary wicking of water (by reducing absorbability) and steam (water vapour) diffusion.
The PIR foam exhibits excellent mechanical performance, durability, low absorbability and other physical and chemical characteristics which mark the material out for application even in the most demanding construction environment types (roofs, floors, flooring, foundations, basement walls, etc.).
Certificates and declarations
Declaration of Performance - Thermano
What is a better thermal insulator, polyurethane or mineral wool?
The main advantages of PIR core panels include (flat roofing insulation system): (a) better thermal insulation performance: λ = 0.023 (Thermano) vs. λ = 0.034–0,040 (high quality mineral wool) (b) lower density: 32 kg/m3 (Thermano) vs. 100–150 kg/m3 (mineral wool) (c) high compressive strength: 200 kPa (Thermano) vs. 40–50 kPa (mineral wool) (d) water absorbability resistance: absorption level: <2% (Thermano) vs. 100%< (mineral wool) (e) high biodegradation resistance: resistant (Thermano) vs. prone (mineral wool)
Are the Thermano panels fire resistant?
The Thermano panels feature PIR (polyisocyanurate) core which when exposed to fire forms a scorch layer that isolates the material interior from fire.
