ᐅ Parapet Height for Windows, Balconies & Railings – What to Consider?

If the window sill is built during the shell construction, it is done in steps of 12.5cm (5 inches). If the sill is built up to 1 meter (39 inches) high and approximately 18cm (7 inches) for the floor structure (screed with underfloor heating, ventilation system, flooring) is subtracted, this would result in a sill height of 82cm (32 inches). If that is too low for us, we could build it half a brick higher, resulting in a sill height of 94.5cm (37 inches). Is that correct, that you can only choose between these two measurements? We would actually prefer 90cm (35 inches), but I guess that’s not possible, right?

What is the usual standard height for a typical window sill?
Best regards,
SabineWhat is considered standard? I would say up to 90 cm (35 inches) is common, but that’s just my opinion. We planned our kitchen so that the countertop runs into the window recess as the window sill. For this, we chose a sill height of 87 cm (34 inches).
Note: In my opinion, the sill height refers to the height of the underside of the window sill or countertop.

Bieber081518 Oct 2016 18:33The parapet height for standard windows in our case was 87.5 cm (35 inches) measured from the finished floor level according to the plan. The top edge of the window sill was then at 90 cm (35.5 inches).
Do we actually know anything about the construction method? I originally thought it was a modular system—until I learned that so-called plan blocks are used. These are large units, factory-cut and delivered to the site, where they are assembled and glued together according to the plan. Practically no cutting is done on site.
In this specific case, you simply have to ask (planner, architect, shell contractor, etc.). I would guess that at the window it probably doesn’t matter much. If a half block is needed all around for the room height, it might make sense to round up to a full block.

However, it costs the mason time and often material, so an additional charge is applied here.

How did you arrive at the 87.5 cm (34.4 inches) sill height? One meter (about 4 brick courses) minus the screed? That seems too low considering the thickness of the screed.

How did you arrive at the 87.5cm (34.5 inches) parapet height? From the rough floor level, ours was 107.5cm (42.3 inches). However, this was messed up during planning, so an additional 20cm (7.9 inches) of standard-sized masonry blocks were built on top of the finished parapet (interestingly, everything was correct on the upper floor).
We built with calcium silicate plan blocks, or rather XL panel elements, however you want to call them... Basically a kit for assembling and bonding, pre-cut at the factory. Your idea of the brick module doesn’t apply here.
In our case, everything is planned in a 12.5 cm (5 inch) grid wherever possible. Our planner’s reasoning was that this makes things easier for the masons and therefore more cost-effective for us. The window above the kitchen countertop has a rough opening sill height of 125 cm (49 inches), which results in a finished sill height of 107 cm (42 inches) after the floor buildup. We specifically wanted the window to be positioned well above the countertop so that the countertop does not run into the window reveal, so this should be fine.
What puzzles me now, however, is that you all seem to have such “low” sill heights?! Our other windows with sills on the upper floor (both children’s rooms, bedroom with dressing area, bathroom) all have a sill height of 112.5 cm (44 inches), which is 94.5 cm (37 inches) after subtracting the floor buildup as the finished sill height. I’m wondering if that might actually be too high and am feeling a bit uncertain. During the planning phase, our planner said this was the standard sill height, so we didn’t give it much more thought. It’s still not too late to change it, as construction hasn’t started yet… but for cost reasons, we would want to stick to the 12.5 cm (5 inch) grid (this involves a total of 7 windows!), so the next lower sill height after finished floor buildup would be 82 cm (32 inches)… wouldn’t that be too low?

readytorumble19 Oct 2016 08:00@Lanini: I think your sill height is a bit high.
We are planning a sill height of 126cm (50 inches) from the raw floor level and 106cm (42 inches) subtracting the flooring structure on the ground floor. This concerns six windows, two of which are above the kitchen countertop. We specifically wanted the windows to be clearly above the countertop. Then we adjusted the other four windows because we didn’t want different sill heights.
The other two windows or (lift-and-slide) doors are floor-to-ceiling.
