Insulating a house

Q3ydKbmARU | Posted in Energy Efficiency and Durability on

Dear Sirs: I am building walls on the inside of my kitchen and was wondering what is the best way to insulate the walls. I want to use paper backed insulation with plastic. Should I put the plastic on the back side of the wall then insulate or should I insulate and then put the plastic on top of the insulation on the inside of the walls. Any help and information that you could furnish me will be greatly appreciated. Thanks. [email protected]

    The big box store where you are buying DIY supplies loves to help. Some even have learning seminars and all have huge racks of how to do it books that are very helpful.

    Fiberglass batt insulation with kraft facing goes in with the paper showing. No plastic needed in most climates. You were supposed to post where you live for the most appropriate help. Reread above.

    Not so fast, AJ ... some climate zones are best insulated without a vapor barrier ... climate zone determines procedure.

    Paul, not so fast!!!??? How about you read my post a bit s l o w e r yourself. I quote myself above,"You were supposed to post where you live for the most appropriate help. Reread above."

    Also Kraft facing is very climate friendly.

    Also, I said to hit the stores for help.

    It's like you read one word "kraft" and missed the entire rest of my post and points. If you can't read... Never mind. Nice post. Thanks for straightening out my post. Skiing day beautiful blue sky. Take over for me Paul.

    1. Please tell us where you live.

    2. Unless you live in Alaska or the colder parts of Canada, you probably don't need a polyethylene vapor barrier.

    3. If you are installing fiberglass batt insulation with kraft facing, the kraft paper faces the interior.

    4. If you are installing fiberglass batt insulation, it's really important to pay attention to air sealing. In your case, you should probably follow the Airtight Drywall Approach.

    5. Here is an article about fiberglass batt installation: Installing Fiberglass Right.
