July 2026 – Passive Solar Shading Details Part 1

This new set covers a range of external solar shading strategies for residential windows, across timber frame and masonry cavity wall constructions. With Approved Document O now requiring overheating to be considered in new residential buildings, solar shading is increasingly a core part of the design and specification process rather than an optional extra.

The set includes fixed solar fin and overhang surrounds, a proprietary brise soleil, integrated PVC roller shutters with insect screen in both visible and hidden box configurations, and a lifting/folding timber shutter. Details are provided across timber frame and masonry wall constructions, with a range of window types and materials. Each relevant detail includes annotated sun angles at the winter solstice, spring/autumn equinox, and summer solstice to illustrate shading performance across the year.

Details included in this set:

• DL525 – Fixed PPC coated solar fin and overhang – timber frame and cladding with timber inward opening window 
• DL526 – Fixed PPC coated solar fin and overhang – masonry 150mm cavity brick wall with mixed outward opening window
