Services
Bespoke Windows
We create made-to-measure windows tailored to exact specifications. Clients choose from aluminium, steel, composite, PVCu, or engineered timber frames with unlimited colour options. Our windows accommodate unique shapes and configurations including curved, raked, and pivot designs. Each installation combines thermal efficiency with aesthetic flexibility, ensuring seamless integration with existing architecture while meeting modern performance standards.
Custom Doors
Our door solutions include hinged, sliding, folding, and pivot configurations in premium materials. The slim-framed pivot doors maximise opening width while maintaining structural integrity. Clients select from extensive finishes and ironmongery options with possibilities for tinted or coated glass. Each installation enhances natural light transmission while providing weather protection and security through precision-engineered components.
Structural Glazing
We deliver uninterrupted glass expanses using structural glazing techniques. This includes single or double-glazed units with optional tinting for solar control. Large panels receive additional support through glass fins where required. The system eliminates traditional framing for unobstructed views, suitable for both internal partitions and external facades while maintaining thermal efficiency and structural stability.
Rooflights
Our rooflight systems adapt commercial-grade glazing technology for residential applications. Available as fixed or openable units, they integrate with tiled or felted roofs. The solutions include complete glazed roof structures using patent glazing techniques, ensuring watertight performance and thermal insulation. Designs accommodate both flat and pitched configurations with customisable dimensions.
Curtain Walling
We install continuous glazing systems in aluminium, steel, or timber frames for commercial and residential buildings. These curtain walls incorporate doors, windows, and panels within the structure, creating seamless transitions between elements. Our expertise ensures wind load resistance and thermal performance while achieving striking visual effects through expansive glass surfaces.
