MasterLine 8 window doors are available as single or double doors, both inward and outward opening. It is possible to use window or door hardware on the doors, in this way it is possible to open and lock the doors from both inside and outside as well. The window doors can be chosen with three different threshold solutions: brushes, automatic door latches and with a low threshold bottom profile.
MasterLine 8 balcony doors feature 3 different levels of insulation for high insulated, low energy and even passive houses. These different levels of insulation are achieved by the integration of new and clever materials. The unique concept makes it possible to combine an extensive range of window opening types, design variants, and different levels of thermal insulation. The design variants, each with their own distinct look and feel, make MasterLine 8 suitable for any architectural style.
