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 features a PIR (polyisocyanurate) core which makes the panels a perfect choice for the thermoinsulating layer for heated and unheated floors, as well as balconies, patios, and even the most demanding insulated horizontal structures: patios over heated rooms.]

The outer layer of the Thermano panels is made of aluminium, which reflects and directs the heat from floor heating systems to the building interior.




The lowest thermal conductivity coefficient of all thermal insulation materials (λ = 0.023 (W/mK) means better thermal insulation efficiency. In practical terms, this significantly reduces the energy needed to heat the building, which ensures major financial benefits.


Just an 80 mm thick layer of Thermano panels is enough to assure a thermoinsulating performance comparable to that of a 120 mm thick EPS layer.


The Thermano panels can feature the MASTER join lock which eliminate gaps between the thermal insulation sections.


The compressive strength of Thermano panels is over two times higher than in typical thermal insulation materials. This minimises the risk of surface deformation by pressure.


The maximum absorbability ratio of each panel is 2%, which makes the roof structure extremely impervious to mould and fungal attack even if the roof water barrier fails.


If a flooring layer is flooded, e.g. due to a plumbing or floor heating failure, Thermano will not erode and keep the flooring insulation parameters unchanged.


The panels are quick, easy and clean to install. [Thermano is a perfect choice for heated and unheated floors, as well as balconies, patios, and even the most demanding insulated horizontal structures: patios over heated rooms. The thermal insulating panels can be installed within different flooring types, i.e. laid on ground or floor slabs in residential, industrial and farm buildings.

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.).

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.
