The Purios H is a closed-cell polyurethane system used for the production of rigid spray foam. The system incorporates a new generation foaming agent (HFO) with an ozone depletion potential (ODP) of zero and a low global warming potential (GWP). Purios H is characterised by its sprayable layers (from 10 to 25 mm),

It is a material used for insulating houses. It is also used for thermal insulation in garages, production facilities and livestock buildings. The polyurethane foam (PUR for short) is divided into rigid closed-cell foam and semi-rigid open-cell foam – each with partially different properties.
The closed-cell foam is made up of at least 90% closed-wall bubbles unlike the open-cell foam, which contains at least 90% open-wall bubbles. The differences in density of the two materials translate into different properties.
Used in the construction industry, the PUR foam is a very high-end material for insulating building partitions (walls, ceilings, attics and foundations). With a slightly altered composition, it is widely used in many areas of industry and in everyday life as a foam or sponge.
It is a physical parameter characterising the thermal transmittance of materials. It is defined as the amount of heat flowing through 1 m2 of 1 m thick material in 1 second, assuming that the temperature difference on both sides of the material is 1 K (Kelvin). The unit of thermal conductivity is W/mK.
There are more than a dozen essential benefits of using the right thermal insulation material, but most investors consider two key ones. The first one is the thermal comfort of the residents, while the second one is the savings in energy bills resulting from the best insulation.
