Casement windows are hinged at the side and open outward, offering excellent ventilation and unobstructed views. Our UPVC models feature 70mm profiles, internally beaded frames for security, and multi-point locking systems. Designed to meet Part L regulations, they incorporate 28mm low-emission glass with argon filling for superior thermal efficiency and noise reduction.
Composite Doors
Composite doors combine durability and style with reinforced UPVC frames, multi-layered construction, and advanced security features. Each door includes police-approved multi-point locks, toughened glass options, and energy-efficient insulation. Available in custom colours and finishes, they enhance home security while maintaining aesthetic appeal and long-term performance.
Sliding Patio Doors
Sliding patio doors provide seamless indoor-outdoor living with sleek UPVC frames and large glass panels. Our systems use low-friction rollers and reinforced profiles for smooth operation and longevity. Thermal efficiency is achieved through 28mm Planitherm glass units, while optional safety glass and locking mechanisms ensure security for families and pets.

French windows are elegant, full-height doors that open outward, creating a grand entrance or garden access.
