Slimline window frames are leading the way when it comes to sleek, minimalist window replacements in Surrey and the surrounding area. Modern windows featuring more glass and less frame are specifically designed to flood spaces with warm natural light, making rooms seem that much bigger, brighter, and more pleasing to the eye.

Aluminium windows are at the height of fashion when homeowners seek low maintenance, long-lasting minimalist aesthetics. However, nowadays, modern uPVC windows are also available with slender slimline frames. So, if you’re trying to figure out which window material is best for creating slimline windows, we’ve taken the time to answer three top questions our customers are asking us at the moment.

Are aluminium windows thinner than uPVC?

Typically, aluminium windows have always been considered much thinner than uPVC. High-performance aluminium windows are available with a super slim overall depth of 14mm. Aluminium window profiles should be no less than 1.2mm thick to ensure they’ve been designed with robust strength and safety in mind. Any thinner and they may not be strong enough to take the weight of the glass.

That said, recent advances in uPVC manufacturing processes have made slimline uPVC window frames a viable possibility, opening up minimalist home designs to a wide range of households and lifestyles. Standard uPVC window frames tend to be around 20mm – 28mm wide. In stark comparison, our slimline uPVC windows are fitted with 12% more glass and feature an impressive outside wall thickness of just 3mm. Designed to be symmetrical, this ensures our uPVC windows are much slimmer and more aesthetically pleasing to your home.
