Services
Conservatory Installation
We design and build custom conservatories using reinforced Liniar 6-chamber frames and Ultraframe roofing systems. Our installations feature insulated brickwork, damp-proof membranes, and high-performance glazing to ensure year-round comfort. With over 3,000 completed projects, our experienced team delivers durable structures that enhance property value while maintaining thermal efficiency through 28mm sealed units and warm-edge technology.
Orangery Construction
Our orangeries combine traditional aesthetics with modern insulation using Ultraframe's tested roofing systems and structural aluminium frames. We incorporate brick pillars and perimeter flat roofs to create grand spaces with natural light while maintaining energy efficiency. Each project includes thermal PVC cappings and integrated ventilation to ensure comfortable temperatures throughout the year, backed by 25-year durability guarantees from Ultraframe.
UPVC Windows
We install Swift's 8-chamber uPVC window systems offering superior insulation compared to standard 3-chamber frames. Our windows feature Planitherm glass with argon gas filling and warm-edge spacers to achieve A+ energy ratings. The multi-chambered profiles enhance security while reducing heat loss, with foils available in rosewood and golden oak finishes to match various property styles across Norwich and Norfolk.
Bi-Fold Doors
Our bi-fold door systems combine sleek aluminium frames with 28mm insulated glazing units for seamless indoor-outdoor living. The weather-sealed tracks and multi-point locking systems ensure security and thermal efficiency. Available in various configurations, these doors feature low-threshold options for accessibility and come with optional integrated ventilation to maintain comfortable temperatures when closed.
Warm Room Design
We create temperature-controlled warm rooms using high-performance insulation materials and underfloor heating options. These spaces maintain consistent climates through advanced glazing technology and thermal construction methods, making them usable year-round even in Norfolk's colder winters. Our designs include humidity control features and energy-efficient heating solutions to reduce running costs while preserving aesthetic appeal.
