Crawl Space Insulation Before & After Photos

This homeowner in Groton, CT called us with issues with her crawl space being very humid and moist. When our Home Comfort Specialist arrived, he noted that one of her issues was that she had a bulkhead door, but not an inner door to separate the exterior and interior of the home. This presents a few problems for the home: during the summer, warm and humid air comes into the home. In the winter, cold air leaks in, causing cold floors. This causes a lot of mold as well as higher energy bills. 

Fogarty's was able to help this customer with this issue. We were able to install an Everlast™ crawl space door in the home. The Everlast™ crawl space door is 1/2" thick polyethylene, which is solid and durable. It is a custom sized door with thick weather stripping and anchors into the foundation. It will never rust, rot, or need paint. It is also a barrier between the volatile outside air and the inside of the crawlspace. It is an airtight access door that will last forever with less air leakage and condensation. This customer was so excited to not have any more mold or sagging floors! 

Insulating Rim Joints and Crawl Space Ceiling In Ashford, CT

Vents and other leaks to the outside were sealed, using our insulated vent covers. Walls were insulated with SilverGlo.

This homeowner in Jewett City, CT called us hoping to get his three season room insulated. Some homes or additions are designed with floors that have the outside air under them. Other times a home or addition was originally used as a summer home or “three season room”, and was converted to all season heated space later. When the outside air flows under a floor it feels very cold and uncomfortable in the winter - especially with ceramic tile, linoleum or laminate floors. Since the floor is the surface of the room we are in contact with most, it’s very important to fix, in order to be comfortable. There are two issues - air leakage through the floor, and conductive heat loss through the floor, because heat moves from more to less through solid materials. Even if there is fiberglass batt insulation in the floor, because it sags down away from the sub floor, the same outside air gets over it (“thermal bypass”) rendering it useless. Mold on the floor joists and sub floor is also a concern. Results - cold floors, drafts, uncomfortable rooms, greater overall home air leakage rate, higher fuel and electric bills.

We had the perfect solution for this customer. In this solution, SilverGlo™ foam insulation board is installed across the bottom of the floor joists with special long screws and 3” washers, SilverGlo™ is expanded polystyrene foam with graphite infused into the foam, which bumps up the insulation (“R”) value by 24% over standard EPS foam. Further, SilverGlo™ has a radiant barrier to reflect heat, so the insulation isn’t doing all the work by itself. All seams are sealed. If necessary a skirt board can be installed around the perimeter of the insulation so the edge is not visible. The skirt board may require painting after we are complete. Result - Much warmer floors, less drafts and more comfortable rooms, quieter home, lower fuel and electric bills.

These homeowners in Woodstock, CT had issues with their home being cold. One of the main issues was cold air coming up through their open crawlspace. There was batt insulation in the crawlspace ceiling, but as often happens with batts, it was beginning to sag, leaving space for cold air to get up into the floors and up through the home. This issue would only get worse over time if left unchecked and the cycle will only continue if batt insulation is reinstalled.

We began by pulling out the batted insulation. We then installed our SilverGlo insulation foam across the bottom of the floor joists, or some may call the crawlspace ceiling. The foam is rigid and will not sag or pull away from the joists, there is also a radiant barrier facing on the SilverGlo which will stop conductive heat loss by keeping the warm air inside the home in. The SilverGlo is fastened into place with special long screws and any spaces between them are sealed with expanding foam.

Thanks Dr. Energy Saver by Eco Energy, this home is far more comfortable.
