Attic/Cathedral Ceiling

user-7067054 | Posted in Green Building Techniques on

I have a home that was built in the 70’s in Utah. In the living room and kitchen is cathedral ceiling with only 2×4 rafters. We have very poor insulation and have a lot of problems with ice dams in the winter and a lot of heat gain in the summer. Can you recommend a strategy for improving heat loss/gain and insulation as is and an option for adding depth to the rafters and the best option for new insulation. Thanks for any info.

    Also any info on solar board or reflective material if that offers any r value or help with heat gain. Thanks

    First of all, can you tell us your name? (I'm Martin.)

    Here is a link to an article that explains everything you need to know about improving the R-value of your cathedral ceiling:

    In general, radiant barriers are a waste of money. What you want is insulation (something with R-value), not a radiant barrier. For more information, see:

      Thanks for those. I'll check the link on ceilings.
