I live in Pasadena Maryland. I have a 7'4" crawl space (not a basement) I don't have basement...
windows we have crawl vents as per local code. We also have a escape opening as per local code with a metal cover to the outside. I want to finish the space. The space has a poured concrete floor as per local code, with block walls. 75% of the space is underground. What is the best way to insulate the exterior walls? I have seen many methods over the years. I have seen polyurathane against the block with roll backed insulation in the framed 2 X 4 walls. I have sen 2 X 4 walls with polyurathane on the sheetrock side...I have seen sprayed insulated walls...also styrafome against the block bet
Hi. I apologize for taking 2 weeks to answer. The most cost effective, easy for a DIY, and efficient outcome is to strap the walls with 2x2's and insulate with fibreglass bundles.
Apply a vapor barrier and tape all seams.. This is the most important part for a block foundation. I know that some folks will argue that there isn't much air escape or infiltration ,but the vapor barrier will also stop the heat from from being absorbed by other materials.
