    Cool weatherproofing outside of house

    The concrete blooks between the footing and the siding i have seen an advertisment from a home improvement store, to put insulation on to the cement bricks to help keep cold air from entering the basement and the floors. Was just wondering how efficiant this is and cost savings. i would love to see you air a program on this as i watch you every week.

    thank you

    Foam by itself isn't a great idea for it will get beaten up by lawn equipment. Also the foam itself must be UV proof. So you'd be covering the foam with something hard.

    Then you would have covered any way to see termites which would love the gap between the foam and the block / covering.

    Why do you have holes / cracks in your block?

    They are usually refering to a piece of foam on top of the foundation block to seal the rim joists to the foundation sill plate. As a retrofit, it's common to use spray foam to seal the air gap that often forms. Thsi si done from the inside in the basement.

    Being from Wichita, you may now already have solved the prob or be knee-deep in snow. Insulation is applied on the inside, but if you just have minor cracks (for whatever reason) on the outside you can touch up with the sprayfoam. Be quick & easy-does-it. It'll help till you can install a permanent solution to the cold.

    Also check with your insurance company FOAM has to be at least 8 inches above any dirt or ground cover other wise the termite bond maybe voided.
