uPVC Windows
Our uPVC windows combine modern security features with thermal efficiency. Available in multiple styles including flush sash and sliding options, they feature multi-point locking systems and achieve high energy ratings. Custom colour choices ensure property-specific aesthetics while maintaining durability against Welsh weather conditions.
Composite Doors
Engineered for maximum security and insulation, our composite doors incorporate reinforced frames and advanced locking mechanisms. With diverse design options including decorative glass panels and custom ironmongery, they enhance property aesthetics while meeting Secured by Design standards for enhanced home protection.
Composite Decking
Low-maintenance composite decking solutions merge wood-like appearance with weather-resistant materials. Available in various finishes including Teak and Silver Ash, these slip-resistant surfaces require no painting or staining, offering durable outdoor living spaces suitable for both residential gardens and commercial venues.
Lantern Roofs
Slim-profile lantern roofs maximise natural light in extensions and conservatories. Available in Contemporary, Regular, and Square designs, they incorporate thermally efficient glazing units and meet BSI strength standards. Our largest models span 1.5m x 3m, creating expansive sky vistas without compromising structural integrity.
Glass Balustrades
Frameless glass balustrades provide modern safety solutions for stairs, balconies, and outdoor areas. Using toughened safety glass with minimal metal fixings, they maintain unobstructed views while meeting building regulations. Custom configurations accommodate both straight and curved installations across residential and commercial properties.
