Services
Aluminium Bifold Doors
Our aluminium bi-folding doors create seamless transitions between indoor and outdoor spaces. With slim profiles and high-security locking systems, these doors are available in 200+ RAL colours. Custom configurations accommodate various aperture sizes while maintaining thermal efficiency. Trade customers benefit from technical support and sample provision for client consultations.
Heritage Windows
Modern aluminium heritage windows replicate traditional steel profiles with enhanced performance. These slimline windows offer superior strength-to-weight ratios and low maintenance requirements. Available in dual colours and with optional trickle vents, they suit both period and contemporary properties while meeting current building regulations.
Secondary Glazing
Secondary glazing systems improve thermal efficiency and noise reduction in existing windows. Our made-to-measure solutions maintain aesthetic integrity while achieving U-values as low as 1.8 W/mK. Ideal for conservation areas and listed buildings requiring non-invasive upgrades with minimal visual impact.
Aluminium Roof Lanterns
Contemporary roof lanterns maximise natural light in extensions and conservatories. Constructed with thermally broken aluminium frames, these units combine sleek aesthetics with energy efficiency. Custom sizes and configurations ensure compatibility with various architectural styles while maintaining structural integrity.
