Designed for cold climates, the Cold Climate Damper (available with 2.7, 3.4, & 4.0 models only) is powered by a heavy-duty actuator that is tested to 60,000 cycles. The damper door is insulated to R-10, (upgradable to R-50), to help ensure an air tight seal whenever your whole house fan is not in use. The damper can be installed vertically or horizontally.

For regions of the country where it gets extremely cold, the damper door of the R-50 version is insulated with a combination of standard fibreglass insulation and VIP panel (vacuum insulation panel) to achieve its R-50 insulation rating.

Upgrade Price: $199.00$249.00
