Performance considerations
Performance requirements for The Boat House were shaped by the riverside location, the need for minimal sightlines and the requirement to control solar gain while maintaining clear views across the River Dart.
All glass within the sliding doors and window elements was heat soak tested and specified with a neutral solar control coating. The coating provides 70% light transmission with a solar factor, or g-value, of 35%, allowing high levels of daylight into the interior while filtering infrared solar radiation to help reduce overheating.
The slim sliding door systems use thermally broken aluminium framing with insulated glass units, supporting thermal performance while maintaining the minimal appearance required for the river-facing elevation. The use of solar control glass was particularly important for this riverfront property in Devon, where large glazed openings were needed to frame the water without creating excessive internal heat gain.
The combination of slim sliding doors, pivot doors, bespoke aluminium windows and high-performance glass allowed the renovation to improve comfort, daylight and views while retaining the controlled detailing required for a historic riverside building.
Technical details
- Slim framed sliding doors: 21mm sightline; max tested sliding pane 8.5m² up to 4.0m high and 500kg; glass thickness 26–32mm; typical Uw > 1.1 W/m²K; Air Class 4 / Driving rain Class 7A / Wind Class C4/B5; sound insulation up to 39dB; PAS 24 security; project used linear and pocket sliding configurations to suit different riverside openings
- Structural glazing: thermally broken fixing system; 63mm profile depth; max glass thickness 41.5mm; expected Uw 1.1 W/m²K; minimum fixing setback 55mm; profile height 60mm; structure deflection allowance 5mm; used as part of the wider riverside glazing package where frameless glass was required
- Solar control glass: heat soak tested glass units used within the sliding doors and window elements; neutral solar control coating with 70% light transmission and 35% g-value to reduce solar radiation while maintaining clear views across the River Dart
- Bespoke aluminium windows: dual-colour anodised finish with natural silver anodising internally and red-brown anodising externally; upper floor bay glazing designed to replace the original timber bay window and maximise views across the river and Mill Pool Dam
- Slim pivot doors: slim aluminium pivot door configurations incorporated within the wider glazing package to provide access while maintaining consistent frame finishes and minimal sightlines
Riverside glazing for heritage renovation projects
The Boat House shows how a historic riverside building can be upgraded with slim architectural glazing while retaining the character of its original material envelope.
This approach is well suited to architects and specifiers working on heritage renovations where slim sliding doors, pivot doors, bespoke aluminium windows and solar control glass need to be coordinated with retained masonry and sensitive waterside views.
