Tegotherm Polyiso
High resistance and thermal insulation rigid expanded polyurethane (PIR) boards

The rigid expanded polyurethane boards
With their excellent performance, Tegotherm Polyiso boards are suited for the most severe temperature and humidity application conditions. They are made of rigid expanded polyurethane, a light material with strong resistance to mechanical stress, thermosetting, and both high and low temperature resistant.
The thermal insulation properties of the Tegotherm Polyiso range, together with negligible water absorption and good dimensional stability, are the result of the innovative cross-linked closed cell production process.
Advantages
MINIMUM THERMAL CONDUCTIVITY
HIGH RESISTANCE TO EXTREME TEMPERATURES
PERFECT DIMENSIONAL STABILITY
GREAT MECHANICAL PERFORMANCE
MINIMUM WATER ABSORPTION
LONG-LASTING BOARDS
TEGOTHERM POLYISO SUPER
Tegotherm Polyiso Super is protected by international patent PCT/IB2015/000025.
Developed in the Research & Development labs and directly created by IWIS technicians, the product is the result of synergy between the companies of the Group: on one side the great production capabilities of the companies specialised in insulating products, on the other a highly technological facer produced in a plant that is one of a kind.

Tegotherm Polyiso Super is a rigid PIR foam board with high thermal insulation characteristics: the low λD=0.023 W/mK thermal conductivity value is possible thanks to the new gas-proof multilayer coating, which keeps the expanding gas within the foam, therefore preserving the thermal performance levels in the long term. The surface coating consists of an aluminium layer, which further increases the insulating properties of the board
