Beyond this, the amount of tradeoff that is permitted for fenestration when following the UA alternate method or whole building performance paths also continues to be capped in the 2018 IECC. Guards are required to be a minimum of 42" in height. One of thesedesignated the UA alternate methodonly permits tradeoffs between different elements of the building envelope. Those dimensions would yield a net clear opening of only 3.3 sq. 0000035112 00000 n Similar to option 1 above this ensure the device acts as somewhat of a guardrail by not allowing any opening larger than 4 inches.

Egress windows provide emergency exits to homeowners in case of fire or other life-threatening situation. (A) When anchors are attached to hollow or solid aluminum frames, the reinforcing plate shall be coated or protected so as to minimize electrolytic action between unlike metals. The other three compliance paths for residential construction in the 2018 IECC permit some tradeoffs in levels of energy efficiency from one building component to another. 3.

(2) The manufacturer or authorized representative, of any window unit intended for installation in new construction or remodeling shall submit evidence satisfactory to the Division that the complete installation with approved anchors has successfully withstood the drop test specified in paragraph 4.5.3(d)(2) of ANSI/ASME A39.1-1991, Safety Requirements for Window Cleaning, which is herein incorporated by reference, without failure of the frame at the point of attachment of the anchors and without detachment of the window unit from its attachments to the wall section. Answer:The BC Building Code is a provincial regulation for new construction and building alterations, establishing minimum standards for safety, health, accessibility, fire and structural protection of buildings, and protection of the building or facility from water and sewer damage. If the point of intersection of a vertical line from the slope value with a horizontal line from the sill width value falls in the unshaded area, washing windows from a standing position on the sill is permissible. Having a 24-36-inch buffer under the bottom portion of the window makes it much less likely that small children will inadvertently put themselves in danger. Therefore, for those homes that fall within the scope of the prescriptive provisions of the 2018 IRC, the geographical locations where impact protection of openings is required are similar to those given in ASCE 7-10 and are primarily defined by design wind speed. In jurisdictions using the 2009 or earlier editions of these two codes, it is essential to verify which set of requirements is to be complied with before beginning a residential construction project. When the distance is less than 6 feet, anchors or equivalent protection as required by Section 3212 shall be required. Figure 1 - SILL WIDTH AND SLOPE As such, it is most commonly applied to R and LC windows and not CW or AW windows.
