Polyurethane is currently the fifth most commonly used plastic in the world. It is used in numerous industries, from footwear, furniture, electronics, automotive, and even construction. In the latter, it is primarily used as a thermal insulation material in the form of panels or spray foam. Its versatility stems from the ability to vary its properties within a wide range by modifying its composition and manufacturing process.

Yes. Polyurethanes are materials that are safe for health and the environment. PIR boards do not contain formaldehyde or other harmful substances. They are resistant to fungi and mould and do not provide a food source for rodents.

The cost of insulation using PIR boards without cladding may initially be higher than traditional materials, but thanks to their superior insulating properties, a thinner layer of insulation can be used, which translates into long-term savings.

Thermal resistance is one of three values that determine the thermal insulation of a building partition. Calculating thermal resistance requires knowledge of the lambda coefficient and the thickness of the material. Formula: R = d/λ, where d is the thickness in metres and λ is the thermal conductivity coefficient.

Thermal resistance R characterises a material of a specific thickness and is equal to the quotient of the material thickness and the thermal conductivity coefficient lambda. The unit of thermal resistance is (m²·K)/W. When selecting insulation material, thermal resistance R is more important than the lambda coefficient itself, as it takes into account the thickness of the material.
