Key Product Features
Composite windows are designed to bridge the gap between traditional timber and modern uPVC products. They offer the durability and low maintenance of uPVC, combined with aesthetic features that replicate the look of timber.
With details like hand-crafted or timber-effect joints, composite windows stand out from standard uPVC alternatives. Most commonly available in casement styles, these windows bring a classic appearance without compromising on performance, though door options may be limited depending on the system.
Customisation Options
Although our composite windows have a timber appearance, they still provide uPVC customisation options. With a range of styles, hardware, and glass styles available, you can give kerb appeal to these windows.
Our glass options include decorative glass to add a traditional touch to your home, such as leaded glass and Georgian bars. In comparison, we can offer obscure glass options if you’re looking for privacy or alternatives for blinds and curtains.

Composite windows are a smart choice for homeowners seeking style and performance. Built from a mix of materials, they deliver strong insulation, long-lasting durability, and minimal maintenance.
These windows often mimic the appearance of timber, giving a high-end, traditional look without the hassle of regular upkeep. They’re also highly weather-resistant and energy-efficient, helping to reduce heating costs over time. With versatile design options, composite windows work well in a variety of property types, blending function with visual appeal.
Colour Customisation
We offer foiled woodgrain finishes to give our composite windows the timber appearance to achieve the trademark look and feel. Although the material of the windows is uPVC, we offer a range of colours to give an authentic timber finish.
Our colour range is available for customisation – whether you prefer a dark wood appearance or a light wood finish, we can tailor these uPVC windows to suit your individual needs and taste.
