New Sash Window System Launch

We’re pleased to share that after several months of development, we’ve officially launched our new sash window system – Slim SS C&W 134 SW42.

This profile has been specially designed for listed buildingsconservation areas, and projects requiring ultra-thin glazing, including slimline and vacuum glass.

It maintains a traditional aesthetic while offering excellent technical performance and high light transmission.

Key technical highlights:

  • Slimmest applied glazing bar – just 17 mm, available in ovolo, lamb, or square styles

  • Profile tailored for thin glazing – maximum internal glazing (glass from Poland) is 16 mm (4/8Ar/4.LE), which means duplex bars cannot be used in these units

  • Perfect for putty-effect and vacuum glass – profile geometry is specifically adapted for these solutions

  • Optional thicker sash – by increasing sash thickness to 54 mm (with external cutback), glazing units up to 24–25 mm can be used

  • Structural glazing bars – 22 mm or 24 mm options remain available for projects requiring a classic “putty-line” effect

Attached are the technical section drawing and photos of the finished window straight from production.
