Project Overview

A contemporary new build extension in Milton Keynes required a high-end glazing solution to achieve its architectural vision. The open-plan kitchen and living area was designed around floor-to-ceiling glass to connect seamlessly with the rear garden. The goal was to install a premium Schüco sliding door system alongside matching windows to maximise natural light, deliver exceptional thermal performance, and create a true indoor-outdoor living experience.

Our Solution

We supplied and installed Schüco ASS 70 sliding doors and Schüco AWS 70 windows throughout the new extension. The solution included:

  • Three-panel Schüco ASS 70 sliding door with one fixed panel and two sliding panels
  • Slim aluminium sightlines for uninterrupted garden views
  • Thermally broken profiles exceeding building regulations
  • Low-threshold track for step-free garden access
  • High-security multi-point locking with finger-safe interlock
  • Matching Schüco AWS 70 windows with side-hung casement openings
  • Powder-coated finish in dark grey (RAL 7016) to complement the extension’s exterior cladding
  • Double glazing with low-E coating and argon gas fill

Installation Process

  • Coordinated with extension build timeline and verified all rough openings
  • Installed reinforced steel lintels above sliding door opening
  • Lifted Schüco ASS 70 sliding door frame into position using precision packers
  • Mechanically fixed frames to new masonry and timber studwork
  • Hung sliding door panels and adjusted rollers for smooth, quiet operation
  • Installed Schüco AWS 70 window frames to side elevations
  • Spray-foamed all perimeter gaps with high-expansion insulation foam
  • Applied internal and external silicone seals for airtight weatherproofing
  • Installed double-glazed units into all windows and door panels
  • Adjusted all rollers, locks, hinges, and handles for perfect operation
  • Completed thorough clean of all glass, frames, and tracks
