UPVC Windows
Our A+ rated UPVC windows combine energy efficiency with enhanced security features. Manufactured using titanium dioxide-infused materials, they resist weathering while maintaining thermal performance. Each installation includes multi-point locking systems and draft-free designs. Available in 16 colour options across contemporary, timeless, and traditional finishes, these windows improve property aesthetics while reducing energy bills through superior insulation properties.
Conservatory Roof Replacement
Transform existing conservatories with our thermally efficient warm roof solutions. The system incorporates insulated panels and optional glazed elements to create year-round usable spaces. Installation includes exterior cladding options in slate or glass finishes. The conversion process maintains structural integrity while improving energy ratings, with completed projects achieving U-values comparable to standard residential roofs through integrated insulation layers.
Home Extensions
Custom-designed extensions using the HUP! rapid-build system combine structural integrity with aesthetic continuity. Projects include integrated glazing solutions and coordinated exterior finishes. Our turnkey approach covers planning assistance, structural engineering, and completion certification. The system allows full interior customisation while maintaining energy efficiency standards through continuous insulation and high-performance fenestration.
Composite Doors
Thermally broken composite doors feature multi-point locking mechanisms and reinforced frames. The manufacturing process incorporates weather-resistant materials with internal insulation cores. Available in multiple designs including traditional panelled and modern flush options, each door includes anti-drill plates and reinforced lock housings. Installation incorporates draught-proofing seals and precision-adjusted hinges for long-term operational reliability.
Aluminium Doors
High-security aluminium patio doors utilise thermal break technology to prevent heat transfer. Available in bi-fold, French, and sliding configurations, they incorporate multi-chambered profiles for enhanced insulation. The systems feature low-threshold designs for accessibility and come with powder-coated finishes in 12 standard colours. Installation includes precision levelling and structural weatherproofing to meet building regulation compliance.
