Hidden Sash Windows

These windows have a slim profile of only 66mm from the exterior that maximises the glazing surface & is able to reach 85% of the total window glazing.  Its design allows for the hidden sash to be maintained from the outside in such a way that it is impossible to distinguish from the fixed zones that the opening has & therefore achieving perfect homogeneity in the facades style.  A 35mm thermally broken area & the insertion of polyolefin sponge in the frame & sash allows it to reach values of up to 1.3 U- Value.



All our systems are factory finished, powder coated to any RAL colour. Dual colour, marine grade in addition to bronze or silver anodized  

Lead time & cost-effective standard colours may apply (dependent on the range)
