When Standard Won't Work
Period Properties & Listed Buildings: Original windows in Georgian, Victorian, and Edwardian properties often have non-standard dimensions and slim sightlines that modern off-the-shelf units can’t replicate. Our heritage slimline units maintain authentic aesthetics while providing modern thermal performance.
Architectural Projects: Architects and designers specify glass for visual impact, not just function. Custom-tinted glass, specific Georgian bar configurations, unusual shapes, and exact dimensions enable design intent to be realized.
Unusual Frame Sizes: Older properties, custom builds, and unusual installations often require specific sizes that don’t match standard manufacturing runs. Made-to-measure means we match your frames exactly, eliminating gaps and drafts.
Performance Requirements: Projects with specific U-value targets, acoustic requirements, or solar control needs benefit from custom glass specifications tailored to the application rather than compromised by standard options.
Renovation & Restoration: Matching existing specifications in renovation projects ensures visual consistency across all windows in a property.
