The 2018 IRC requires site-built windows to be tested for design pressure in accordance with ASTM E330. The prescriptive path for residential construction establishes maximum permitted U-factor and solar heat gain coefficient (SHGC) requirements for fenestration (Table R402.1.2).

Similar to egress windows, the minimum sill height is not required for all windows but for windows that meet certain conditions that would require fall protection. My opinion is baths are too dark without some daylight. 29). The best sill In addition, many Caribbean countries have adopted the I-codes in the wake of devastating hurricanes and the earthquakes in Haiti. The 2015 IBC contains requirements for minimum sill heights for operable windows in apartments, townhouses, duplexes and single-family homes.
