These homeowners in East Longmeadow, MA had issues with drafts in their home. One of the sources of these drafts was a whole house fan. Before air conditioning was common in homes, whole house fans were installed in the floor of the attic to pull warm air inside the home out and allow for cooler air to come in through opened windows. With air conditioning, there is no longer a need for such a fan, which is now just another spot for the air the homeowner pays to heat and cool to leak into the attic and out through the vents to the outside.
To seal the fan off, we use our David Lewis Whole House Fan Cover. The cover is made of our SilverGlo graphite infuse insulation board and sealed with expanding foam. The homeowners let us know that they may want to use the fan in the future, so we cut a removable lid out of the top piece of foam board which can easily be taken off whenever the fan is going to be used.
Thanks to Dr. Energy Saver by Eco Energy Solutions, this home is less drafty and the homeowners still have options available for cooling their home in the summer.
