Although opaque doors are included in the definition of fenestration area in the 2018 IECC and 2018 IRC, they are assigned a maximum U-factor of 0.35, separate from the U-factor requirements for vertical fenestration. For vertical glazing, this reduction in design wind speed in ASCE 7-16 results in a reduction in design wind pressure. The intent of this later provision is to permit windows that are equipped with WOCDs to also be used to meet the EERO requirements of the 2018 IRC. To recap, although the average window is three feet off the floor for furniture placement, the safety codes say that your windowsill can be as low as 24 inches. 7GCzsWGi:ZlwV)XO!be\[o4t/ *BU\}+Qzy=A'v#=1jvP:BuZbu;@tzvqFwB#/|*id9j'#E(h/L!`6+;FT 2e{e6MU'`OpRq'Q3:DDDDV(VRk`% OC_w6[p]`K58J1LJnC6}v wU1+9)be_6\CU%+`#z6)AN]j|4qV.\+n3i[~1C2+TgP"]Q%`4F#VFfE>HwJ:*tD MF(wp +U9ELqY V_[ ?cw6%nr=;bGd2q`?aV_+l National Glass Association Fixed or operable windows must include safety glass if they measure larger than 9 feet square, the bottom edge is less than 18 inches above the floor, the top edge is more than 36 inches above.
