Services
Structural Glazing
Our structural glazing systems create seamless glass envelopes for commercial and residential buildings. Using high-performance silicone bonding techniques, we install frameless glass facades that maximise natural light while maintaining thermal efficiency. This solution suits modern architectural designs requiring minimalist aesthetics with robust weatherproofing capabilities.
Curtain Walling
We supply and install thermally broken curtain walling systems that enhance building envelopes. Our aluminium cladding solutions combine structural integrity with energy efficiency, meeting Part L building regulations. These systems are ideal for commercial developments needing durable, low-maintenance exterior finishes with customisable design options.
Ultra Slim Sliding Doors
Our ultra-slim sliding door systems merge contemporary design with functional performance. Featuring advanced weather seals and multi-point locking mechanisms, these doors provide secure, energy-efficient access between indoor and outdoor spaces. Available in custom sizes for both residential and commercial applications.
Roof Glazing
We design and install structural glass roof systems that transform interior spaces with natural illumination. Our roof glazing solutions incorporate laminated safety glass and thermal breaks to ensure comfort and compliance. Suitable for extensions, atriums, and commercial buildings requiring daylight optimisation.
Windows
Our aluminium window systems offer slim sightlines with superior thermal performance. Manufactured to BS4873:2016 standards, these windows feature multi-chambered profiles and secure locking systems. Available in a range of RAL finishes for both new builds and heritage refurbishment projects.
