Abstract: An insulated shutter assembly is installed in a ceiling or other wall of a building and used in combination with a ventilating fan for intake or exhaust, such as a whole house fan. The shutter assembly is insulated to substantially prevent heat transfer by conduction and convection through the shutter assembly when it is closed. An integrated mechanical lock system is used with the shutter assembly to provide a positive force against elastic seals when the shutters are closed to thereby provide an airtight barrier against air movement through the shutter assembly. The individual shutter blades are insulated to provide effective resistance to conductive heat losses when closed, and are also shaped to minimize aerodynamic drag and noise when open. The shutters may be manually locked and unlocked or may be motor actuated. The shutter assembly can thus be permanently installed and when the fan is not in use will effectively block heat transfer whether the building is being heated or air conditioned.
