Table N1102.1.2 Insulation and Fenestration Requirements By Componenta | |
Climate Zone | 5A |
Fenestration U-Factor [BTU/hr-ft2-°F | 0.32 |
Skylightb U-Factor | 0.55 |
Glazed Fenestration SHGC | NR |
Ceiling R-Valuel | 49 |
Wood Frame Wall R-Value | 19 or 13 + 5h |
Mass Wall R-Valuek | 15/19 |
Floor R-Value | 30g |
Basementc Wall R-Value | 15/19 |
Slabd R-Value and Depth | 10, 36 inches |
Crawl Spacec Wall R-Value | 15/19 |
a. R-values are minimums. U-factors and solar heat gain coefficient (SHGC) are maximums. | |
b. The fenestration U-factor column excludes skylights. The SHGC column applies to all glazed fenestrations. | |
c. The first R-Value applies to continuous insulation which is allowed to be applied at the time of finishing the basement, the second to framing cavity insulation; either insulation meets the requirement. | |
