Polyurethane insulation boards are typically a low density polyurethane core with two flexible facings. Examples of typical facings are aluminium foil, glass mat and paper.
Polyurethane insulation boards are produced using a continuous lamination process. Process involves pouring reacting material on to lower facing and passing through a conveyor to cure. Cured boards are then cut to length on line. It is also possible to cut to different widths and cut tongue and groove joints in the edge on the line.
Typical applications include
Polyurethane boards are lightweight and easy to handle. When combined with the correct blowing agent it is possible to achieve aged Lambda values in the range of 0.021 to 0.024 mW/m.K. This means that current u value requirements of building regulations/technical standards can be achieved using the thinner insulation than with other commonly used insulation materials, resulting in potentially more living space in a property.
The insulation performance of a polyurethane insulation board remains constant for the life of the building. It is possible to have a tongue and groove joint between the boards, meaning no thermal bridges and air tight insulation. The boards have good compression resistance, temperature resistance between -25 deg.c and + 90 deg.c (short term exposure up to +250 deg.c is also possible) and biological and chemical resistance. Polyurethane boards are resistant to moisture ingress, do not support growth of fungi. They are non fibrous and do not emit harmful emissions.
Polyurethane insulation boards are suitable for use in residential, commercial and industrial buildings. They can be used for both new build and renovation of existing properties.
