Saving energy with PU foam

Its top ranking in the insulation value table makes construction foam one of the most efficient insulation materials for filling construction joints, for instance around windows and doors. If you compare the properties of PU foam with alternative insulation materials, you will notice that PU foam has very good insulation values and a long lifecycle. This means that assembly foam saves lots of energy very quickly which is good for the purse.

Construction foam as a heating costs brake

The better an insulation material is able to stop temperature equalisation between the inside and outside, the more heating energy it is able to save and less CO2 is emitted into the environment. The main application field for PU foam is the installation of window joints and, to a certain extent, sealing these joints. Even a modern high-tech window is only as good as the insulation in the surrounding joints. A comparison of the insulation materials that can be used shows that PU foam has the lowest thermal conductivity and the best insulating properties. This means: construction foam provides the best insulation. This is due to its closed, fine-cell structure that effectively prevents the transfer of warm and cold. During its 30 year life-span, PU foam therefore saves the most energy.

Saving energy reliably

The amount of energy that an insulation material can effectively save also depends on how reliably the joints are filled. Thanks to its ability to expand to twice its original size after it is applied to the joint, the construction foam guarantees that the joint is filled well and reliably - especially if any unevenness in the joint needs to be compensated. Also, modern PU foams compensate part movements and therefore lower the risk of cracks in the flanks. With respect to mineral wool, the quality of the insulation is much more dependent on how carefully the specialist works and how much time he takes. Gaps in the stuffed wool can cause the insulation material to drop and leave local areas of the joint practically without any insulation. 

Effective protection against moisture with construction foam

Thanks to its closed fine-cell structure, construction foam absorbs almost no moisture. This is why, in contrast to other insulation materials, no water can collect in the construction joints to impair the insulation effect. The functional capability of the construction foam is guaranteed throughout its life-span. This means: PU foam saves energy reliably and permanently.
