IRC Energy Code Requirements & Truss Heel Heights
- Information about ceiling space energy requirements from the International Energy Conservation Code is replicated in both the IRC and IBC.
- IRC Section N1102.2.2 applies to ceilings without attic spaces while Section N1102.1 applies to those with attic spaces.
- It is assumed that attic spaces do not require raised heels in order to meet given R-values. Instead, the insulation must be deep enough to achieve it wherever the construction technique allows it.
