Heritage Aluminium

Our Heritage aluminium windows feature a distinctive ‘stepped’ sash profile, designed to emulate the classic style of mid-19th-century steel windows, such as the iconic Crittall designs. With ultra-slim sightlines as narrow as 59mm, these windows offer an elegant, minimalist appearance that enhances both traditional and contemporary homes. Remarkably, their slim frames are nearly half the width of our PVCu range, maximising light and creating a classical, refined aesthetic.

Why Heritage?

The Heritage aluminium window range offers opening sashes in two depths, with the deeper option accommodating 44mm triple-glazed units for exceptional thermal and acoustic insulation. Outer frames are available in two styles, allowing for either a protruding sash or flush sash appearance to suit your design preferences. A selection of astragal bars ensures an authentic ‘steel window’ style can be effortlessly achieved. Complementary front, back, and French doors are also available to extend the heritage aesthetic throughout your home.

Like the Contemporary range, Heritage windows are offered in 12 standard finishes, including three striking metallic options, with bespoke paint finishes available upon request for a personalized touch. These versatile windows combine period-inspired design with modern performance, ensuring they are not only visually stunning but also highly efficient and durable, perfect for enhancing both traditional and contemporary properties.
