    Default R-value for Plumbing Insulation in Ext. Walls

    I could not find the R-value for plumbing insulation installed in exterior walls in the 2006 IRC. Does any one know the value / code section?

    Thanks,

    Brian

    Brian,

    - P2603.6 Freezing. In localities having a winter design temperature of 32F (0C) or lower as shown in Table R301.2(1) of this code, a water, soil or waste pipe shall not be installed outside of a building, in exterior walls, in attics or crawl spaces, or in any other place subjected to freezing temperature unless adequate provision is made to protect it from freezing by insulation or heat or both. Water service pipe shall be installed not less than 12 inches (305 mm) deep and not less than 6 inches (152 mm) below the frost line.

    Depends on where you are located. Some areas would not require much insulation, other areas may require quite a bit of insulation ... or heat ... or BOTH.

    The code is a minimum document and only addresses the "protection" as it must be "adequate" or ... or don't put the pipes in the walls, attics, crawl spaces, etc.
