Shading & Heat

South-facing conservatories on Heavitree stone terraces can exceed comfortable temperatures on clear July afternoons. West-facing glazing catches low sun across Exeter's ridge — a common issue on properties above the Exe floodplain. Our shading and heat sheet documents both summer gain and winter loss.

Summer Shading

• Roof vent pairs sized for cross-ventilation on still Devon days
• Internal pleated blinds on south roof panels — specified by width, not generic
• External awning zone marked on elevation where garden access allows
• Solar-control glass notation on the material schedule

Winter Heat Retention

Exeter averages mild winters, but stone floors and uninsulated dwarf walls radiate cold at night. We note underfloor heating zones, trench heater positions beneath bi-fold tracks, and thermal break requirements at the house junction.

This sheet is standard in our full package and available as an add-on to entry-level layout sets. Combined with plant zones (Sheet 06), it prevents overheating damage to specimen planting.
