Window Openings in Masonry
Window Openings in Masonry
(OP)
I've been working on a 1-story masonry building, it's an addition off of an existing metal building to provide office space. The site is very isolated, outside of city limits and it's being used to store the clients own materials. I have recently noticed that a 4'x4' opening is shown on the drawings for a 48x48" window. My questions are:
1. What is a standard (or min.) height above the floor slab for the bottom of the window.
2. Will the window fit in the opening, or do I need to change it to the 4'-8" height that I'd originally specified. If I do that, the bottom of the opening will only be 32" off the floor, which now seems awfully low even with a sill block.
The wall is 9'4", and I've got a bond beam at the top and across the top of the openings. The top of the window and door openings are at the same elev.

RE: Window Openings in Masonry
The US Code requirements I have seen, only controls the type of glazing, (requiring safety glass if certain conditions are meet) not sill height. The 2'-8" is a normal sile height.
Many windows are undersized to fit the 48"x48" inch opening. Full sized windows require a 48 3/4" x 48 3/4" opening. Insure the correct window is ordered.

(That 2'-8" sill height still seems low, but I'm 6'7" so probably not the one to pass judgement)
Cheers back at ya.

Also, if your opening is in masonry, you may want to pick a window size that will work the the brick or block coursing.
Just a few thoughts!
