Ideal 7000+ profiles are another system variant of the ideal 7000 series introduced in 2015, which is a response to these growing requirements in the field of thermal insulation of window joinery.
Metal stiffeners in window profiles, due to high thermal conductivity, create a thermal bridge and deteriorate their thermal insulation properties. 7000+ is an innovative technology of co-extrusion of PVC profiles with the use of special thermoplastic inserts reinforced with glass fiber Ultradur® High Speed, developed in cooperation with BASF. These inserts successfully replace the steel used in conventional PVC window frames, providing significantly better thermal insulation properties with the same mechanical properties of the window. Thanks to the elimination of steel reinforcements within the profiles of the Ideal 7000+ series, thermal bridges are limited, and the heat transfer coefficient of the frames for this series is Uf = 1.0W / m2K, which is a very good result for a system with external sealing.
The structure of the profiles also allows for further improvement of the thermal permeability of sections by optionally filling some internal chambers with thermal insulation material.
