Termoimpact

Floor

Grafipol Termoimpact is an expanded polystyrene (EPS) panel with low thermal conductivity, complying with the Spanish technical specifications of the UNE-EN 13163 standard, whose specific raw material increases its thermal insulation power to the same density of conventional EPS.

Given its excellent features, it is recommended to be used as thermal and acoustic insulation for raised floors, especially in those building areas separating homes from uninhabitable or exterior spaces.

This innovative product solves two needs in just one, for it simultaneously serves the purpose of anti-shock sheets and thermal insulation.

It has the main requirements for insulation for this application:

  • It has a resistance to compression of 100 kPa, as recommended by the UNE 92181 standard for use in interior floors as underfloor insulation.
  • It can reduce shock noise levels by 26 dB. Therefore, it complies with the Spanish requirements set by CTE DB-HR for homes.
  • It has excellent thermal conductivity at 0,030 W/mK, which enables higher thermal resistance with little thickness, complying with the demands set by CTE DB-HR and saving those centimetres that hinder free heights in homes.
