Pipe Insulation| Residential | Building Code Officials Summary Pipes carry heated or cooled liquids from boilers or heaters to faucets and other fixtures connected to mechanical HVAC and circulating hot water systems. The energy code requires pipes carrying heated or cooled fluids to be insulated to reduce heat loss from the liquid contained within them and the pipes themselves. This is especially important for pipes carrying hot water, as heating and transferring liquid through un-insulated piping wastes significant amounts of energy.
QUICK FACTS Pipe Insulation - Sections 403.3 and 403.4 2009 IECC R-values need to be in accordance with code; specifications need to be clearly labeled Mandatory for all climate zones
Current Code The 2009 IECC covers pipe insulation in Sections 403.3 and 403.4.
Detailed information can be found at: Insulate Hot Water Pipes for Energy Savings from EERE
Previous Code Older versions of the IECC (2003 and back) were complicated, requiring calculations for a variety of different systems, pipe sizes and locations. The 2006 IECC simplified pipe insulation requirements by removing these calculations and mandating R-2 insulation for Sections 403.3 and 403.4. The 2009 IECC is identical to the 2006 version for pipe insulation requirements save for one modification: the insulation value in Section 403.3 changed from R-2 to R-3.

Exemptions Requirements covered in the 2009 IECC Sections 403.3 and 403.4 are mandatory and universal for all climate zones.
Requirements Building code officials must be aware of the requirements covered in the 2009 IECC and need to ensure that:

Correct insulation is included and inspected Labeling on pipe insulation is clear and identifiable Plans and specs are reviewed and requirements are met
Typical Problems Standard issues/concerns that arise include: Hard to find supply of required insulation Insulation not included in original bid
