Casement Windows
Our casement windows combine modern thermal efficiency with traditional aesthetics. Manufactured to Document L standards, they feature multi-chamber systems and weathertight seals to achieve A+ energy ratings. These windows reduce heat loss, draughts, and external noise while enhancing property security. Available in white, golden oak, and rosewood finishes, with custom RAL colours on request.
Composite Doors
Our composite doors offer superior security and insulation with solid cores and 70mm steel-reinforced frames. Designed to mimic timber aesthetics without maintenance drawbacks, they include multi-point locking systems compliant with British Standards. Available in white and wood grain finishes, these doors improve thermal performance and property value while meeting Secure by Design criteria.
Conservatories
Tailor-made conservatories in UPVC or aluminium provide year-round living space with thermal efficiency and security. We offer lean-to, Georgian, Edwardian, and gable styles, all designed to complement property architecture. Our factory-assembled roofs ensure perfect fit, while Pilkington glass options enhance light, insulation, and aesthetics.
Roofline Products
BBA-approved UPVC soffits, fascias, and guttering protect against weather damage with 10-year material guarantees. Our cast-iron effect downpipes and ventilated fascias prevent water ingress and wood rot. Complete roofline overhauls include repairs to rafters and bargeboards, ensuring durability and aesthetic cohesion with existing property features.
Energy-Efficient Glazing
A-rated double glazing reduces energy bills by up to 680 annually while lowering carbon emissions. Our systems incorporate argon-filled glass, laminated panes, and self-cleaning coatings for durability and low maintenance. Enhanced security features include hook locking mechanisms and reinforced frames, meeting modern building regulations for safety and performance.
