Excellence in comfort
The new SlimLine 68 outward opening windows allow for maximum daylight access and feature excellent weather resistance and optimal insulation properties. The ultra slim sight lines ensure that even in small openings daylight access isn’t compromised in favour of performances. This makes SlimLine 68 windows the ideal solution for renovation purposes in domestic buildings and new builds as well.
SlimLine 68 vents can be glazed from the inside as well as the outside, and are available on a standard and a HI insulation level.
