ᐅ Options for Roof Windows

Hello everyone,

We have a bathroom on the upper floor with an area of about 8 m² (86 sq ft). Originally, we planned (in coordination with both the planner and the carpenter) to install two roof windows measuring 78 x 114 cm (31 x 45 inches) (W x H).

However, the roofer now says that due to the battening, neither the 114 cm nor the 98 cm height will work, and only windows sized 55 x 78 cm (22 x 31 inches) are possible (don’t ask me what went wrong here – I assume the detailed planning could have been more thorough). Well, that’s how it is now.

We are concerned that it might be too dark. Apparently, wider windows—something like 140 x 78 cm (55 x 31 inches)—are not available. As an alternative, a daylight spot was recommended to us, but we’re not very convinced by this, as it would require some ductwork on the attic floor and would probably increase the cost.

I find it hard to imagine the size – will two smaller windows (55 x 78 cm) be sufficient to provide comfortable natural light in the bathroom with a 45° roof pitch?

Do you know of any other solutions—for example, manufacturers that offer windows in different formats? The roofer is apparently using brands like Lux or Oto.

Thanks for your input.
Best regards

Ah, the kids' bathroom.
Is a vertical window strip not an option?

No, unfortunately the ring beam is there – by itself it’s already about 30cm (12 inches) thick. That means the top edge of the clerestory window would have been a maximum of 1.2m (4 feet) high – especially since the masonry is already built 😀
The 1.34m (4 ft 5 inches) wide roof window will probably have to be electric as a last resort.

...or the good old pole 😉

Yes, that is also possible. I thought if I write this here, I would be back at square one 😀

Again??? Not for me! I’m into the ’60s style, basically retro, and doing things by hand doesn’t make you any less smart 😉

Well, fully designed houses from top to bottom, so naturally the rod for the overly high planned roof window doesn’t fit.
The roofer wanted to offer us electrical work with solar panels – but unfortunately never mentioned what the extra costs would be 😀 We’ll probably have to discuss it with him again and then see if we go with the rod.
