Sandwich panel SP2E X-PIRS

Sandwich panel SP2E X-PIRS is available in thicknesses 120 - 160 mm.

Low U-value and proper joint design together with wide thickness range make this sandwich panel an ideal solution for cold storage buildings. Innovative technology increasing strength parameters of the panel provides for load-bearing capacity up to 40% higher comparing to standard solutions.  

The core of this sandwich panel is made of rigid, HCFC-free, self-extinguishing and sustainable polyisocyanurate foam (PIR). Its excellent thermal insulation properties enable the decrease of panel thickness which transfers directly to lower transportation and assembly costs, as well as significant savings of building's life cycle costs.
