Project Overview
A detached property in Buckingham underwent a refurbishment of an ageing rear extension that had become dark, poorly insulated, and out of step with the rest of the house. The existing windows were small and set high in the wall, offering little light or connection to the garden, while the old patio door was draughty and difficult to operate. The owners wanted to open the space up with floor-to-ceiling glazing and a slim-framed patio door. The goal was to install full height glazing windows and an aluminium glazing patio door to flood the extension with daylight, improve thermal performance, and create a seamless flow between the interior and the garden.
Our Solution
We supplied and installed a bespoke full height glazing and aluminium patio door package tailored to the refurbished extension. The solution included:
Full Height Glazing Windows:
- Floor-to-ceiling fixed glazing panels with ultra-slim aluminium profiles for maximum glass area and uninterrupted garden views
- Thermally broken aluminium frames to eliminate cold bridging and prevent condensation
- Double-glazed units with low-E coating and argon gas fill for improved thermal efficiency
- Toughened safety glass throughout, with laminated glass to lower panels where required
- Matching aluminium cills, trims, and weather seals for a clean, watertight finish
Aluminium Glazing Patio Door:
- Slim-profile aluminium casement patio door with two side-hung opening panels (active and passive leaves)
- Fully glazed leaves to match the surrounding full height glazing
- Thermally broken profiles for energy efficiency and condensation control
- Multi-point locking system on the active leaf with anti-snap cylinder
- Flush bolts to the passive leaf top and bottom
- Heavy-duty stainless steel friction hinges for smooth, controlled operation
- Low-threshold cill for step-free garden access
- Concealed drop-down weather seals for superior draught protection
Finish:
- Powder-coated aluminium in a colour selected by the owners to complement the refurbished extension
- Matching handles and hardware across windows and door for a unified appearance
Installation Process
- Carried out a detailed site survey with precision laser measurements of all openings in the extension
- Confirmed glazing configurations, door specification, and colour with the owners
- Coordinated with the wider refurbishment works to ensure correct sequencing
- Removed the existing windows and old patio door carefully to preserve surrounding brickwork and internal finishes
- Disposed of all old frames and glass responsibly
- Inspected and prepared the structural openings, lintels, reveals, and sills
- Installed steel reinforcement where required to support the full height glazing spans
- Lifted aluminium frames into position using precision packers and laser levels for accurate alignment
- Mechanically fixed all frames to the structure, ensuring zero movement
- Fitted double-glazed sealed units into the fixed glazing panels and both door leaves
- Hung the patio door leaves on stainless steel friction hinges and adjusted for smooth operation
- Installed the multi-point locking mechanism on the active leaf and fitted flush bolts to the passive leaf
- Spray-foamed perimeter gaps with high-expansion insulation foam
- Applied internal and external silicone seals for airtight, watertight weatherproofing
- Adjusted all hinges, handles, and locking points for reliable daily use
- Completed thorough clean of glass, frames, tracks, and surrounding areas
- Conducted a final walkthrough with the owners to confirm satisfaction
