About Slimline

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.

Why our Slimline system is a great solution

Our Slimline system has been developed for maximum light intake with less uPVC frame and more glass, thus providing increased natural light. Through our impressive design, we were able to create our exclusive Slimline range – which gifts you a thinner proportion of frame and glass for your windows and doors.

Combining the performance of casement windows with spectacular design, our Slimline range has a low proportion of frame to glass which allows up to 12% more glass. This results in a sleek and impressive window, which is ideal for both modern and traditional properties and allows light to flood into your home.

The aesthetic design ensures that your windows and doors will enhance the look of your property, rather than detract from its overall appearance.

Technical Information

Weather Resistance

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.

Integral Drainage

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.

Slender Design & Clean Lines

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.

Top Grade uPVC

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.
