N1102.2.4 (R402.2.4) Access Hatches and Doors

Residential Code 2015 of Utah > 11 [RE] Energy Efficiency > N1102 (R402) Building Thermal Envelope > N1102.2 (R402.2) Specific Insulation Requirements (Prescriptive) > N1102.2.4 (R402.2.4) Access Hatches and Doors
JUMP TO FULL CODE CHAPTER
Access doors from conditioned spaces to unconditioned spaces such as attics and crawl spaces shall be weatherstripped and insulated to a level equivalent to the insulation on the surrounding surfaces. Access shall be provided to all equipment that prevents damaging or compressing the insulation. A wood-framed or equivalent baffle or retainer is required to be provided when loose-fill insulation is installed, the purpose of which is to prevent the loose-fill insulation from spilling into the living space when the attic access is opened, and to provide a permanent means of maintaining the installed R-value of the loose-fill insulation.

Exception: Vertical doors that provide access from conditioned to unconditioned spaces shall be permitted to meet the fenestration requirements of Table N1102.1.2 based on the applicable climate zone specified in Section N1101.7.
