The longest pelmet ever?
Design Principle 2: Catch and store energy
I spent quite a few months thinking about the best way to build a 7m long pelmet, and came up with this approach...
...90x45mm pine battens were screwed into the box beams on the ceiling, supporting the structure. 75x19mm pieces of pine were attached at an angle to the battens so that they run vertically and a small chock of wood was added to brace them onto the rail brackets. The weather boards were nailed onto these mini studs. I added some extra support in between the curtain rail brackets using metal bracing off-cuts. I added a plain pine cornice and oiled and varnished the lot, so that it ties in with the rest of the room.
The diagram below shows how the pelmet prevents convection currents in winter, during summer our eaves do most of the work by preventing any sun from hitting the north (sunward) facing windows. Sun reflection off the decking and the external temperature transfer heat through the glass during summer. We close the curtai…
