uPVC flush sash windows
The sash sits flush with the frame, the way a timber window does — made in our own factory in Liniar profile.

Why flush sash
A flush sash closes level with the outer frame instead of standing proud of it. That is how traditional timber windows look, which is why flush sash suits conservation areas and period properties.
We have fitted them in St Albans.
- Liniar Resurgence is A++ energy rated and ready for triple glazing
- Tested to PAS 24
- Mechanically jointed or Timberweld corners for a timber look
- Dummy sashes and mock sash horns for the look of a traditional sash window
Victorian terraces
For Victorian terraces, a vertical slider sash is usually the better match. Ask us at the survey and we will tell you which suits the house.
