uPVC Windows
Our uPVC windows combine energy efficiency with security, featuring advanced double-glazing technology that reduces heat loss and lowers energy bills. The multi-chambered frames provide excellent thermal insulation while maintaining aesthetic appeal through various design options including A-rated glass configurations. With low-maintenance profiles resistant to warping and fading, these windows offer long-term durability and enhanced property value through improved energy performance and noise reduction.
Aluminium Doors
Aluminium doors deliver exceptional strength and security with slim sightlines maximising natural light. Our thermally broken profiles incorporate polyamide insulation for energy efficiency, while multi-point locking systems ensure maximum security. Available in over 200 RAL colours, these doors feature durable powder-coated finishes resistant to corrosion, with options for low thresholds and concealed trickle vents to meet modern building regulations and aesthetic requirements.
Conservatories
We create bespoke conservatories using uPVC or aluminium systems that blend functionality with architectural elegance. Our designs include traditional orangeries, contemporary garden rooms, and Edwardian styles with 10-year guarantees. The structures incorporate energy-efficient glazing, secure locking mechanisms, and optional underfloor heating integration, providing year-round usable space that enhances property value and living comfort.
Bifolding Doors
Our aluminium bifolding doors feature 60mm thermally broken profiles with 132mm sightlines for maximum glass area. The dual roller system enables smooth operation of panels up to 1m wide, with security features including 3-star cylinder locks and shoot bolt mechanisms. Available in inward or outward opening configurations, these doors create seamless indoor-outdoor transitions with optional solar control glazing and integral blinds.
Roof Lanterns
Aluminium roof lanterns provide natural light enhancement with slimline profiles and thermal breaks for energy efficiency. Our systems feature toughened glass units with low U-values, secure perimeter locking, and weather-resistant seals. Available in traditional or contemporary designs, these lanterns complement both modern and period properties while meeting current building regulations for thermal performance and safety.
