Lightweight acoustic insulation for wooden floor in an apartment on the Willemsparkweg in Amsterdam

Combined with floor heating from Uniwarm


Amsterdam has a rich collection of beautiful, classical buildings. Living and working in such buildings is becoming more and more popular. However, before this is possible, the buildings have to be thoroughly renovated. Particularly the acoustic insulation in these old buildings is outdated. Standard products rarely offer a sustainable, reliable and straightforward solution.

Impact sound must not be allowed to become a nuisance.

The building at Willemsparkweg 29 in Amsterdam was precisely such a project. The renovation to turn the building into luxury apartments meant, among other things, that the wooden floors had to be fitted with comfortable underfloor heating. Those same floors also had to be soundproofed in order to fulfil the requirements in the Buildings Decree [Bouwbesluit]. Steps had to be taken to ensure that impact sound in these apartments would not cause nuisance to neighbours.

From a technical perspective, heavy, conventional insulation was not an option.

The Uniwarm company in Vorden, which is a specialist in underfloor heating, was in charge of the work. From a technical point of view, a layer of underfloor heating with heavy conventional insulation was not an option in the building because it would require reinforcement of the beam construction which was structurally impossible. Uniwarm asked specialists from Imbema SMT for assistance because they have already provided reliable solutions in previous Uniwarm projects.

Acoustic insulation using Grei 8 lightweight insulation matting.

After they had assessed the options, our specialists came up with a solution. The underfloor heating would be combined with a dry construction floor. The acoustic insulation took the form of Grei 8 insulation matting from Isolgomma. This matting, which is based on recycled EPDM rubber, is only 8 mm thick, lightweight and extremely easy to work with.
