Windows
We offer a comprehensive range of double and triple-glazed windows in uPVC and aluminium, designed for energy efficiency and durability. Our products include sash, Residence 9, and wood-effect options, all featuring A++ energy ratings and 23 standard colourways. Each installation enhances thermal performance, reduces noise, and increases property value while meeting British manufacturing standards.
Conservatories
Our conservatories combine style and functionality with 100mm A++ energy-rated frames, double or triple glazing, and heat protection features. Available in Edwardian, Victorian, and modern designs, they are built to last with durable materials and thermal efficiency. Each project includes expert installation and compliance with current building regulations.
Warm Roofing
Warm roofing systems transform conservatories with insulated solid or tiled roofs, achieving U-values as low as 0.12 W/mK. These weather-resistant solutions improve energy efficiency, reduce noise, and increase property value. Installed using trusted brands like SupaLite, they offer configurable designs and long-term durability for existing or new extensions.
Internal Doors
Aluminium and uPVC internal doors enhance light and space with slimline profiles and low-maintenance finishes. Available in hinged, sliding, or pivot configurations, they provide acoustic comfort and design flexibility. Each bespoke solution includes expert installation, tailored to match residential or commercial interiors across Hampshire.
Porches
Custom-designed porches add security and kerb appeal with multi-point locking systems and weatherproof materials. Options include pitched, gable, or flat roofs in uPVC or aluminium, with decorative glass and colour-matched finishes. All installations meet British security standards and Secured by Design accreditation for enhanced protection.
