Window Installation
Our energy-efficient uPVC and aluminium windows combine thermal performance with security. Available in casement, sliding sash, and flush sash styles, they feature A-rated glazing to reduce energy bills. Custom finishes and hardware options ensure seamless integration with property aesthetics while maintaining low U-values for year-round comfort.
Door Installation
We supply and install secure composite, uPVC, and bi-fold doors with advanced locking systems. Our thermally efficient designs include Residence Collection options matching window aesthetics. Features like reinforced frames and multi-point locks provide enhanced security while maintaining visual appeal for modern and traditional properties.
Conservatory Installation
Our Ultraframe conservatories offer versatile designs including Victorian, Lean-To, and T-Shape styles. Available with tiled, glass, or lantern roofs, they incorporate thermal insulation and low-emissivity glass. Bespoke colour options and integrated blinds allow customisation while ensuring year-round usability and improved energy efficiency.
Integral Blinds
We install maintenance-free Venetian-style Uni-Blinds within double/triple-glazed units. These made-to-measure systems offer manual or electronic operation with solar control benefits. Available in multiple colours, they enhance thermal regulation while eliminating cleaning requirements through sealed-unit integration.
Extensions
Our hup! system extensions use prefabricated insulated panels for rapid installation. This lightweight construction method creates energy-efficient spaces with 10-15% more internal area versus traditional builds. Compatible with various roof styles, it allows seamless integration of windows, doors, and thermal-efficient designs for modern home expansions.
