Aluminium windows

For commercial or cutting edge projects, aluminium windows are often a must. Our range of aluminium windows are available in any RAL colour and offer superb thermal efficiency, as well as the sleek good looks associated with aluminium. We also offer a range of aluminium residentail, commercial and bi-fold doors.

Timber windows

Timber windows are still preferred by many who live in heritage properties. Our range of traditional timber windows offer the classic good looks of an old-fashioned window coupled with the modern day advantages of double-glazed thermal efficiency.

Secondary glazing

For many homes that feature traditional or decorative glazing, replacement is simply not an option. But how do can householders benefit from the advantages of PVCU double glazing? Secondary glazing provides the answer. Our range of secondary glazing can reduce outside noise by up to 80% as well as dramatically improve a house’s thermal efficiency.


For loft conversions and other eaves rooms, skylights are an essential addition. Our skylights meet all the latest building regulations, are simple and straightforward to install and offer excellent thermal efficiency.

Vertical sliders

PVCU vertical sliders are the perfect compromise between a traditional sliding sash window and the modern-day benefits of thermal efficiency and low maintenance. We supply the industry-leading VEKA vertical slider.
