SL 68 Slim Frame Aluminium Windows
Reynaers’ Slimline 68 window system is specifically designed to meet the demand for an outwardopening window with very slim profiles.
Particularly suited to use in residential properties, this window maximises the glass area to let in lots of natural daylight. The slim frames and clean lines make this window ideal for both contemporary and more traditional properties, as the design of the window mimics the sight lines of the original steel-framed windows. Its 68mm frame depth makes it perfect as a replacement window as it usually fits within the existing plaster line.
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.
