Our windows are more than just style
We know that you want much more than just looks when you choose sliding sash uPVC windows from Progress Windows. However, we would highlight the strong design that underpins our products and sets our windows apart from our competition.
We us a unique profile system to manufacture our sliding sash uPVC windows. Although originally designed about 10 years ago when we took all of the best elements from windows systems around then, it is a relatively new profile system. This has enabled us to create something unique in the market place.
Our sculpted system is designed to give the window a great aesthetic finish and to look elegant rarely found in a way not often found in building products. We use curves to soften the appearance of the window and give it a more attractive look that will impress you and those who see your home.
The jambs, sash sections and mid-railing are produced in very slim profile sections. This aims to recreate and mimic a traditional timber sash window. If our sash window is needed to replace an existing timber sash, then we understand that you will want the window to be sympathetic to the original style of the sash window but without the huge price tag.

Sash Horn Windows
Our Sash Horn windows allow you to keep the authenticity of your property with style. Our Sash Horns are a continuation of the frame itself instead of the usual method of achieving this by simply gluing on the extensions.
Our industry leading sash horn windows provide the traditional aesthetics of yesteryear combined with 21st century materials which offer superior performance and functionality.
Sash horn windows were originally designed to give the sash window stability, but the advent of uPVC windows removed that need. Older buildings can preserve the classic look of wooden box-sash windows, whilst maintaining the authenticity of any property.

All the windows installed by Progress Windows undergo a rigorous hand finishing procedure by our skilled staff:
- Our sash jambs are CNC machined to allow tighter tolerances, a better fit and an overall higher quality finish.
- We use a continuous Eurogroove detail to allow the fitment of wrap-around shoot-bolt hardware.
- We ensure that we use an uninterrupted gasket seal around the sash perimeter with additional horn seals to ensure a great seal.
