How to insulate water pipes

  • Check pipes before insulating. Don’t insulate until any leaks are repaired and pipes are properly supported.
  • To be effective, insulation must touch the pipe.  Gaps between the insulation and the pipe allow cold air to penetrate, which increases the chance of freezing.
  • Don’t take short-cuts where insulation is difficult to install. Any spot that’s left uncovered or inadequately covered could freeze.

Types of Pipe Insulation Two types of pipe insulation are commonly used:

 

Unfaced fiberglass batts work well on pipes in areas such as attics and crawlspaces where people won’t often be present. Tubular foam is a better choice for areas where people may be present.  These areas would include garages, utility rooms and basements. Match the inside diameter (ID) of the insulation to the outside diameter (OD) of the pipe.

 

Spiral wrap tape, thin strips of fiberglass and “bubble” products  are not acceptable because the insulating value is too low.

 

Minimum R-value requirements are listed below.
