TR-31
Façades
Grafipol TR-31 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.
With a thermal conductivity of 0,031 W/mK, this material is recommended for façades and vertical partitions in contact with uninhabited spaces. Due to its excellent features and specific design, it enables compliance with standard requirements regarding energy savings as set in Spanish CTE DB-HE with minimum thickness.
Panel length may be cut to size to adjust it to the height between storeys and avoid thermal bridges between horizontal joints. The panel’s side cuts are mechanised as half lap joint for easy installation and to avoid thermal bridges in vertical joints.
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.
