Thermal Insulation

PVCu is a very poor conductor of heat and therefore makes an excellent insulator. A material’s U-value measures its ability to insulate, the lower the value the better the insulant. REHAU frames have been tested and proven to nearly 60% more heat than typical older frames. Conserving this energy saves you money on your heating bills.

REHAU PVCu is difficult to ignite and will self extinguish when the source of heat is removed. As part of FENSA building regulations are strictly adhered to which includes for example: fire escape hinges and safety glazing.
