Insulation under slab

Grafipol (TR-32, TR-31 y TR-29) is an expanded polystyrene (EPS) panel of 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.

With a thermal conductivity from 0,032 W/mK to 0,029 W/mK, this material is specially recommended for slab concrete floor in contact with the outside or in contact with non-habitable spaces where the thermal insulation requirement is a priority. Due to its excellent features and specific design, it enables compliance with standard requirements regarding energy savings as set in the Spanish CTE DB-HE with minimum thickness and a simple installation.

The product characteristics, its low weight, half-lap joint machining and its great adhesion with adhesives, both cement-based and polyurethane, allow an exceptional fixation to the support, achieving a uniform surface without linear thermal bridges (in joints between pieces) and point thermal bridges (in mechanical fixings).

It can be manufactured in any thickness without losing thermal properties, that means, without its thermal conductivity value worsening, as it is stable in all its thickness.
