Window Styles and Specification

To help you visualise what your new sash windows will look like, we’ve listed some of the more popular window designs to give you some idea of the variety available. The design of the Georgian bar layout changes the appearance of windows, so it’s vital to select those that match your current windows or those that existed previously.

The Perfect Match

Aesthetically, Timberweld® joints will blend in with all architectural styles, Georgian, and Victorian, and will be suitable for use in both conservation areas and in the most contemporary developments.

The technology is material neutral and in the case of PVC-U, Bygone sash windows will be the perfect match for casement windows and doors that are offered with Timberweld®.
