Thermal and Sound Insulating Filling for Wooden Floors from Special Expanded Polystyrene with Flame Retardant

Coefficient of Thermal Conductivity:
λ = 0,056 W / mK
Thermal Resistant for thickness d=50mm
R = 0,893 m2 K/W

Based on the Building Regulation, the buildings should be drawn and manufactured so as to protect the tenants from each form of noises within their residence, when the noises do not come from themselves. With the sound insulation we try to protect the users of a particular space from annoying and unpleasant sounds that are characterized as noises. Although characterizing a sound as noise includes many subjective elements (ex. hearing music too loud, can please someone while this might be noise for someone else), the only certain is that all of us, at some time, we have been bothered by some noise.

The DIN 4109 model distinguishes two ways with which the sound is transferred. Transfer via air (airborne), usually exterior noises of the building, and transfer via solid material (impact noises), usually noises inside the building. Impact noises can simply come from walking, moving appliances and furniture, wrong placement of home appliances etc, and can become particularly annoying in modern buildings, when it has not been taken care of sound insulation of the horizontal and vertical division of the apartments.

The necessary sound insulation from impact noises cannot be simple, as per example placing double glasses in order to decrease the exterior noise caused by air.

STYROFILL, is the only easy and economic way of filling wooden floors without any unpleasant surprises. Due to its particular characteristics (it does not absorb humidity and smells, does not maintain fungus, does not stale, does not cause itch to the craftsman that places it, it allows the airing of wood and does not maintain the flame), it constitutes the ideal solution for the problem of sound insulating floors from impact noises, while at the same time it additionally offers heat insulation.

It is used in nailed wooden floors (by filling the gaps it eliminates the noise that comes from walking or by the fall of objects) and after many trials, it has a certificate from the National Technical University (NTUA)- Laboratory of Technical Materials - Laboratory of Accoustics, which declares that it has Sound Insulating Faculty Lnw = 53 dB. The results have shown that in order to have satisfactory output in the sound insulation of wooden floors, it must be combined STYROFILL with flexible anchors (you will find details in the technical characteristics form).
