With windows accounting for up to 30% of total heat loss and ever-increasing energy fuel costs, it’s important for you to choose an energy-efficient double-glazed window which also looks the part.
Traditionally, the only slim frame windows on the market were aluminium windows, with thin metal frames around larger panes of glass, while standard uPVC windows had a thicker frame. But drawing on our 40+ years of experience, we have designed our exclusive line of slim frame windows in uPVC that combines the best of both.
With 12% more glass than a standard window, our ultra slim profile uPVC windows are the thinnest uPVC windows in the UK and will fill your home with light – creating a space that feels bright and spacious.

Our Slimline windows are fitted with:
Your new Slimline windows or doors will be completely draught proof and watertight. The Slimline profile is produced with all weather bubble gaskets (seals), fused to both the inner and outer frame section.
The bubble gaskets are hollow and offer greater compression and remain in-line with the profile for a neater appearance. They are fused to the profile, which means they can never shrink back, reducing the chance of leaks or unpleasant draughts in your home.
To enhance the weather resistance further, our Slimline system is installed with a purposely built drainage system that directs any water penetration away and towards the external drainage route.
Whilst all the profiles remain technically the same, the Slimline system offers a choice of Bevelled or Ovolo beading, depending on your preference.
The windows were designed to be symmetrical – with respect of all flat surfaces being similar in width. This ensures that the window is much slimmer and more aesthetically pleasing for your window.
The European committee standards state that uPVC must have the highest category (CAT A) outside wall thickness of 2.8mm – the Slimline system is 3mm. Together with 5 chambers, it offers superb frame strength and rigidness that will last for years.
