Air sealing options

caryfitzhugh | Posted in Energy Efficiency and Durability on

Hello,

I’m doing a double stud wall in VT – and am looking into air sealing options.

I have seen people use spray foam around windows and edges and that seems great, but also really expensive for the purpose.

I’ve read a little about kanuf ecoseal, but that seems a pro-line product, and not something that is easily obtainable.

What are some other options available? Would Prosoco Spray Wrap MVP be something that could be used in a similar fashion (seems I can order that).

Any other suggestions?

    Cary,
    Most builders tape their sheathing seams with Zip System tape or a similar high-quality tape, and seal penetrations and the cracks between window rough openings and window frames with a combination of tape, caulk, and canned spray foam.

    If you invest a few hundred dollars in tapes, caulk, and canned spray foam, you'll get a better return on investment (in terms of future energy savings) than you will with almost any other energy upgrade measure.
