My house design has 2 deep, long balconies off the bedrooms on the upper floor. The decks have been designed with parapets; the build is by MBC Timber Frame and it will be a cold roof construction.
The architect is doing all the necessary for building regs sign off and it's nearly there, but they are flapping about ventilation of the decks. Their concern is that the cold roof on the decks must be vented, but they don't want to put any vents through the vertical face of the cladding that will be on the outside of the parapet. As yet, I haven't seen the type of vent that they are trying to avoid, but does anyone have any other solutions for venting the roof other than going through the cladding? I've seen a few ideas where the air flow goes to the edge of the deck then up through the inside of the parapet, but I'm not sure if this would give sufficient air flow and achieve the necessary ventilation level.
Any suggestions welcome.
