MasterLine 8 Windows & Doors

MasterLine 8 is the innovative window and door system from Reynaers at Home that maximises natural daylight in the home while offering the ultimate in performance.

The system offers a wide range of designs, perfect for any style of building, with the narrow frame / large pane combination making breathtaking views a possibility like never before. Add to this impressive scores on acoustics, thermal insulation, and air- and water-tightness, and it’s clear to see why Masterline 8 is the obvious choice for any home.

MasterLine 8 windows feature three different levels of insulation, offering solutions for high insulation and low energy. These are achieved by integrating new and ‘smart’ materials. The High Insulating Plus (HI+) variant, for example, features innovative insulation bars which use a low-emission foil, thus improving the insulation value by reflecting and retaining heat. MasterLine 8 doors are available in two levels of insulation for customisable energy efficiency.

MasterLine 8 windows and doors allow for a water-tightness of 900 Pa, reduced air loss at 600 Pa air pressure, and excellent sealing properties. These ultimate performances are achieved by the overall concept and the increased overlap of the central gasket in the windows, delivering guaranteed performance.
