Does anyone 'know' of an building code approved window for above tub use?? When windows get placed in a position that is too high off the ground, protection measures, such as window opening control devices, are looked at as a way of providing a level of safety given the scenario.

Section R703.4 of the 2018 IRC requires self-adhered membranes used as flashing to comply with AAMA 711-13 and fluid-applied flashing to comply with AAMA 714-15. In the 2018 IECC, there continues to be four energy conservation compliance paths for residential construction: 2. The sill of the window is 290 mm above the interior finished floor and the interior finished floor is 3 220 mm above the exterior adjacent ground level. For a simple residential building or house, a minimum of 15 % area of the room is allowed to provide for window openings. The use of protective wood panels as an alternative to impact-resistant glazing or shutters continues to be permitted for one- and two-story, single-family dwellings, duplexes and residential care facilities.

Tables R301.2(2) and R301.2(3) of the 2018 IRC give the design wind loads for glazed openings based on the design wind speed of the specific location where construction is to take place, the mean height of the building and its exposure to wind. There is also no limit on the percentage of roof area containing skylights. Replacement windows installed in building meeting the scope of this code shall be exempt from the maximum sill height requirements of Sections R310.1 and R310.2.1 and R310.2.2, provided the replacement window meets the following conditions: 1. The method for determining the ERI is now required to be in accordance with the RESNET/ICC Standard 301, which covers how to calculate the ERI score, compliance software tool certification and provides sources for input values not specified in the 2018 IECC. In mid-level climates zones 4 and 5 (Northern Tennessee to Southern Wisconsin), the U-factor is not to exceed 0.48. As the last two options are somewhat similar, the first option is more of a permanent solution such as a rail system for example.

The design wind pressure values obtained from the 2018 IRC are to be multiplied by 0.6 for the purposes of comparison to the Design Pressure rating of the fenestration product obtained by testing in accordance with the 2017 edition of AAMA/WDMA/CSA 101/I.S.2/A440 (NAFS-17). Similar to option 1 above this ensure the device acts as somewhat of a guardrail by not allowing any opening larger than 4 inches.
