Bifold Doors
Award-winning bifold doors combine slim aluminium frames with advanced security and thermal performance. Available in multiple configurations, these doors maximise natural light and create seamless transitions between indoor and outdoor spaces. Customisable options include finishes, handle designs, and panel layouts to suit both modern and traditional properties.
Sliding Doors
Ultra-slim sliding doors feature high-performance stainless steel running gear for effortless operation. Available in configurations up to 24 metres wide, they offer severe weather resistance and low U-values. Options include pocket sliding systems and corner designs to enhance architectural aesthetics while maintaining energy efficiency.
Heritage Doors
Heritage doors replicate traditional steel designs with modern aluminium construction. Thermally broken frames meet Building Regulations Part L standards while offering PAS 24 security accreditation. Available as bifold, sliding, or French door configurations with narrow mid-rails for authentic period aesthetics.
Glass Roofs
Custom glass roofs include lean-to, lantern, and terrace systems with solar-control glazing. Thermally broken aluminium rafters support spans up to 6 metres, while easy-clean coatings reduce maintenance. Designs integrate seamlessly with existing architecture for extensions or outdoor living spaces.
Internal Partitions
Frameless and framed internal partitions provide acoustic insulation up to 36dB. Systems include sliding, bifold, and slide-and-turn configurations with optional integrated blinds. Designed for residential and commercial spaces, they offer flexibility between open-plan and defined areas while maintaining visual continuity.
