Pitched roofs

Solutions

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.

Benefits

SUPERIOR INSULATING PERFORMANCE

SUPERIOR INSULATING PERFORMANCE

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.
ECONOMICAL

ECONOMICAL

The complete removal of cold bridges (in the over the rafter installation) and high insulating performance help reduce heating bills.
DURABLE

DURABLE

The material for the Thermano panels is the most durable thermal insulating material in the construction industry with a service life comparable to the overall building live cycle time: it may last for generations.
ECOLOGICAL

ECOLOGICAL

The product is safe to the natural environment at the production and disposal stages. The panels are made of a material that is 80% recyclable, and in many ways too.
EASY AND QUICK INSTALLATION

EASY AND QUICK INSTALLATION

When compared to traditional thermal insulation methods, Thermano requires less material, while the installation process is less time-consuming and labour-demanding, which means lower building costs.

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.
