this box, which did not have a potential over-heating problem. This configuration contains just 3 nest chambers. West-southwest is not as bad as south, but the afternoon sun could well be a problem.
4 things should keep the temperature within reasonable limits:
• The front is 24mm thick - 2 layers of 12mm plywood.
• The shaped battens cover about half of the front and provide shade from sun directly into the entrances.
• It is painted white.
|The battens keep the entrances in the shade. The tweeter is attached to the bottom of the box with Velcro.|
