OPTIMISED ISOTHERMAL CURVE
The central position of the glass means that both the temperature curve within the construction and the weight distribution are virtually parallel, and centred to the window level. Both these factors ensure the ideal transmission of the temperature and load curve into the structure.The installation depth also allows the window system to be installed in combination with flush-mounted (concealed) sun protection with an insulation thickness of just 200 mm, in the pre-wall installation format tried and tested in passive-house construction.
