Pitched roofs
Superior thermal insulation
Meet the state-of-the-art thermal insulation system for pitched roofs of new and refurbished buildings, with any roofing material. The Thermano panels are an excellent over the rafter insulation system which eliminates cold bridges.
Thermano applications
Thermano is a perfect insulating system for pitched roofs of new and refurbished buildings. The unique advantage of the panels is their installation variants: over the rafter, under the rafter and in-rafter.

Installation
The panels are quick, easy and clean to install. Thermano is a perfect choice for over the rafter, under the rafter and in-rafter installation, either on its own or combined with other thermoinsulating materials.
Pitched roof over the rafter installation
The PIR panels the Thermano products are made of are virtually the only thermal insulating materials for over the rafter installation. This installation style radically eliminates heat loss over cold bridges. Given the wide daily temperature amplitudes in the Polish climate zone, the Thermano manufacturer highly recommends its product for local projects. A similar (outer) installation system has been applied in years for thermal insulation of walls.
Pitched roof in-rafter installation
The in-rafter installation variant consists in mounting the Thermano panels between the rafters. This method is most preferable during roof renovations that are mainly intended to improve the thermal insulating power of the structure. In reality, the in-rafter thermal insulation is always done with either over or under the rafter installation.
Pitched roof under the rafter installation
If you need to avoid cold bridges and cannot install the insulation over the rafters, an optimal solution is to lay the Thermano panels under the rafters.
Installation of over-rafter double-layer insulation on a pitched roof
The assembly of two layers of insulation panels provides perfect protection against cold and heat. An additional advantage is the excellent pressure and gas tightness of the entire system.

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.
Manufacturing technology
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.).

FAQ
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.
