HeavyFoam HD Foam® Plus

Worldwide soundproofing solutions

HD Foam® Plus it is a hybrid PU foam.
HD Foam® Plus it is the only certified (ASTM D3574) material that has controlled density per cm³ with double structure: half open cell for sound absorbtion and half closed cell for sound insulation.
HD Foam® Plus it's also the best material on the market for thermal insulation.
HD Foam® Plus can be mounted between gypsum plasterboards, woodpanels etc.
Between 2 layers of gypsum plasterboard, a 5 cm thickness HD Foam® Plus panel has a Rw=40 dB (similar to STC).
If use without rigid material, HD Foam® Plus it is very good for sound absorbtion on low frequencies.
We recommend the structure with HD Foam® Plus and Sonoblock® Blocktec for the best sound insulation. This structure won 1st place at MusikMesse Frankfurt 2011.
At a thickness of only 8 cm, this structure has a STC of 75 dB.
Recommended structure: Gypsum plasterboard 1,2 cm / HD Foam® Plus 5 cm / Sonoblock® Blocktec 70 3.6 mm/ Gypsum plasterboard 1,2 cm

Noise is one of the worst causes of stress in our society. Turn your house into a peaceful place to relax by insulating all the walls with HD Foam® Plus.
The kids can then turn up the volume upstairs while you relax in peace in the sitting room downstairs. Thanks to its special composition and properties, HD Foam® Plus has a unique way of creating quiet living space.

Physiological - insulation without the side-effects
Healthy building techniques are an important issue that determines the living quality of a house. HD Foam® Plus has no fibres to affect respiration and does not give off any vapour. No health and safety measures are required during installation either. No wonder, because the same material has been used for decades in high quality mattresses.

Conventional insulation materials often sag when used with wooden or metal constructions. A decrease in sound & thermal insulation properties is the result, which can practically hardly ever be remedied. Thanks to the unique structure of HD Foam® Plus, however, its shape remains stable for decades without sagging and eliminates acoustic & thermal bridges completely.
HD Foam® Plus - acoustic & thermal insulation for generations!
