crawl space nightmare

I have been reading posts and have noticed that most everyone insulated their floors with rolled insulation. Is there any reason not to use the styrofoam type for insulating directly under a floor over a crawl space?

stryrofoam, no, EPS(expanded polystyrene), yes. At big box stores in blue or pink. It also act as moisture barrier.

crawl space nightmare

I have a 1500 sf home. It was built in 3 phases w/3 different foundations; part telephone poles, part poured cement, part rocks/cement blocks. No central heat, just a wood stove, so no ducts, etc. Plenty of ventilation under the house, lots of air gets in there. No floor insulation, none of us had a brain back then. We use about 7 full cord of wood each year to heat our house, which is a lot more than others we know with larger homes. So I am looking for advice on how to best insulate our floors and or crawl space perimeter. The front of the house is so close to the ground that it is more of a flat on your belly kind of crawl, not for the claustrophobic! I have been reading advice on crawl spaces, insulating and vapor barriers and so far I am still kind of confused. Help! Thanks, LizRead More

Wet OSB under siding -- maybe

Dubyatee on Oct 15, 2011

Hi! A friend is helping us with electrical work, and recently did the rough-in for a bunch of external light fixtures and outlets. That meant that he cut through our new siding, and the Tyvek and OSB walls underneath. Before we had the rough-in inspection, it rained a few times, and water came into the house through the openings around the electrical boxes. I am not concerned about water that came into the house, because I can see whether it dried. But I wonder whether water got between the Tyvek and the outside of the OSB and whether I should be concerned about mold development. Should I be? How do we dry that out? He wants to install the external fixtures now, but I wonder if that means that we would be cutting off the needed airflow to any wet areas. Thoughts??????? Thank you!Read More
