MasterLine 8 HI+

MasterLine 8 HI+

MasterLine 8 'High Insulating Plus' window

Ultimate performances

The MasterLine 8 platform with its 40mm thermal break ensures an Uf value as low as of 1,2 W/m²K for a frame-vent section of 119mm on the ‘High Insulating+’ insulation level with triple glazing. The ThermoPlastic Elastomer (TPE) central gasket in combination with low emission foils on the insulation bars offer a window solution for passive housing on a frame depth of 77mm.

The HI+ variant is composed of profiles with noryl insulation bars, PEX insulation foams, EPDM glazing gaskets and a TPE central gasket.
