uPVC Windows
Our uPVC windows combine thermal efficiency with modern design, featuring multi-chambered frames and double/triple glazing. Available in casement, sash, and tilt-and-turn styles, they reduce energy bills while enhancing security. Customisable colours and finishes ensure seamless integration with any property, offering decades of durability without warping or fading.
Aluminium Doors
Aluminium doors provide sleek aesthetics and robust security with slim frames and multi-point locking systems. Available as bi-folding, French, or front doors, they resist corrosion and require minimal maintenance. Thermal breaks enhance insulation, while RAL colour options allow full customisation to match modern or traditional properties.
Conservatories
We construct conservatories in Edwardian, Victorian, and lean-to styles using uPVC frameworks and energy-efficient glazing. Optional Leka warm roofs improve insulation, while integrated heating and electrical systems ensure year-round usability. All projects include planning assistance and a 10-year guarantee on structural integrity and installation quality.
Bi-Folding Doors
Aluminium bi-folding doors create seamless indoor-outdoor transitions with minimal sightlines. Their weather-resistant design and multi-point locks ensure security, while low-E glass options maintain thermal efficiency. Custom configurations accommodate openings from 2 to 7 panels, available in any RAL colour for aesthetic consistency.
Composite Doors
Composite doors merge durability with kerb appeal, featuring reinforced polymer skins over insulated cores. Available with decorative glazing and matching side panels, they exceed PAS 23/24 security standards. The non-porous surface resists cracking, fading, and moisture ingress, maintaining appearance with minimal upkeep over 30+ years.
