What makes sliding sash windows unique?
Sliding sash windows are designed with two sashes that glide smoothly up and down, giving homeowners full control over ventilation. Unlike timber windows (which suffer from maintenance issues), our modern uPVC versions combine practicality and durability with authentic detail.
From astragal bars to sash horns, these windows capture the character of period properties while delivering the functionality, security, and thermal efficiency modern homeowners expect.
Where sliding sash windows fit best
These windows are particularly suited to period properties, conservation areas, and restoration projects where maintaining the home’s style is essential. Their period charm makes them indistinguishable from original windows.

Really good and reliable company
I bought the exterior door and I love it. Phil from the sales department offered me several solutions to make me happy with colours, materials and prices. He followed me through the entire process and always answered all my questions and concerns. With him, I obtained a colour that was not that easy to get from other companies.
The installation team was also really nice. In particular, there was a guy from Bulgaria who did an amazing job in a couple of hours and left everything nice and clean.
I would definitely recommend this company 🙂
