I have a question, actually I’m trying to identify my problem so I can solve it. My home was built with a full 8′ basement under it. There was an existing garge, the house was built 14 feet away from that. After the house foundation was in, there was a crawl space put in to connect the house to the garage and it is approximately 7 ft wide by 14 ft long. Crawl space was dug out completely, walls poured, plastic layed down, and a foot or two of stone put in. Floor in crawl space is made out of 2 X 12 with 12″ of insulation between. The room above the crawl space acts as a laundry room, and it has always been a cold room, not unusual for it to be 10 degree’s or more lower than the rest of the house. When the rest of the home is 70 degree’s, the laundry room is 60 degree’s, but if you check the temperature right in front of the dryer, temps go down at least another 5 degree’s. On extremely cold nights it can dip even more. I’m not sure if I should blame the coldness on the crawl space or the dryer vent or on both? Crawl space floor is ceramic tile. The crawl space has no vents but the floor is insulated with 12 inches of fiberglass. There is a heater vent that goes thru the insulation out into the crawl space. Any idea’s anyone? I was not sure if the crawl space should have had a vent or two in it? I was not sure if there was any type of special vent for the dryer that is insulated, can’t find one locally. Clearly the dryer vent has something to do with the coldness though, just wasn’t sure what I could do about that. Typical vent on the dryer, one that goes thru the wall and has the “flap” on it that opens when dryer is on. Thanks in advance for any help you can offer….
