DAMTEC® Eco-friendly Impact Sound Insulation

DAMTEC® – Your ECO Sound Choice

With over 250.000 square meters installed in Ireland, Damtec is the market leader in sound impact insulation.

All our DAMTEC products  comply with Technical Guidance Document E of the Irish Building Regulations.

DAMTEC Standard products are intended for use directly under floor coverings as a means of reducing the impact sound transmission between floor levels. These products can be either loose laid or adhered and come in standard thicknesses of 3mm, 4.5mm and 6mm.

KRAIBURG Relastec have carried out independent testing in accordance with EN ISO 10140-3 on the weighted reduction in impact sound pressure level and rated the subsequent results according to EN ISO 717-2 to evidence compliance with Technical Guidance Document E of the 2014 Irish Building Regulations which amongst other criteria demands a weighted reduction in impact sound pressure level of 17dB minimum.

DAMTEC Eco Sound Insulation


As a recycling specialist, KRAIBURG Relastec have for many years been committed to the protection of the environment. Every year, we process and recycle about 85,000 tons of old tyres, closed-cell rubber and rubber production scrap. From these raw materials, we produce high-quality granules based on our internally developed formulations. These granules make up more than 90 % of the material used in our finished products. All our products are 100 % recyclable without loss of quality.

Protecting the environment is part and parcel of what we do every day!



DAMTEC® Advantages and properties

Icon Damtec Sound Insulation

  • outstanding structure-born sound insulation (impact sound deadening / vibration absorption)
  • reduction of structure-born noise protects the basic structure of machine foundations as well as of engineering works from buildings to bridge constructions
  • good inside dampening behaviour with optimal performance in the low frequency ranges („droning noise“ barrier)
  • low dynamic stiffnesses and optimal natural frequencies / resonance frequencies
  • increased noise control / sound proofing with minimal additions to the overall floor height

Clicking SoundsIcon Clicking Sound
eliminates hollow clicking sounds and reverberations (floor to ceiling noise) under hard floor coverings
Moisture ResistanceIcon Moisture Resistance DAMTEC
superior resistance to moisture absorption and rot degradation
