Curtain walling systems provide the perfect solution for the external cladding of any building capable of allowing in large amounts of natural light through large expanses of clear glass.

This creates a feeling of space and provides the perfect interface with the outside world, all while maintaining the safety, security, and comfort levels of the building’s internal environment for the benefit of its occupants.

The system offers both single- and double-glazed options and is based around a box and plate configuration for ease of fabrication, transportation, and on-site installation, and has been used for domestic and commercial applications such as shops, schools, hospitals, office blocks, and factory units.

It incorporates a co-extruded pressure plate, and this forms a thermal barrier as well as external gaskets to speed up and simplify glazing.

The system is extremely practical and versatile and may be complemented by many other products to be found within our range, including windows, doors, rain screen panels, louvers, ventilators, and sun shading.


Our shopfronts can come with clear or tinted glazing (with or without glazing bars and mullions), bespoke door handles, and a fantastic range of factory-applied, powder-coated colours from both the RAL and British Standard palettes.

We can provide the colour you want or we can match your corporate or branding requirements. Our aluminium shopfronts offer a wide selection of window and door arrangements to suit every kind of location and can be traditional, versatile, and economical.

With the modular design afforded by aluminium shopfronts, interchangeable and security solutions can be achieved where windows can be repaired, replaced, or even reconfigured to take account of the changing business environment.

All of our shopfronts and entrances offer a full range of standard and specialised door hardware for security and ease of access.
