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

It’s enough for ventilation, but the window won’t be fully open. This is probably not a big issue in your situation, but I wanted to mention it.

Hello everyone,
we have a bathroom on the upper floor with an area of about 8 m² (86 sq ft). We originally planned (both with the designer 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 battens, the 114 cm (45 inches) height and even the 98 cm (39 inches) height won’t work—instead, only 55 x 78 cm (22 x 31 inches) is possible (don’t ask me what went wrong here—I assume the detailed planning could have been done more thoroughly -.-). Well, that’s how it is now. Hello,
as a non-expert, I would think that with suitable header beams (also called lintels or supports) it should be possible to install the originally planned windows.
If this was agreed on beforehand, the cost of any necessary header modifications would not be your responsibility, but that of the carpenter. (Disclaimer: layperson’s opinion!)
I would recommend having a direct conversation again with your carpenter (possibly with the designer present as well). You had a reason for your planning, so I wouldn’t accept a simple “it can’t be done” without further explanation.

Sebastian7912 Aug 2015 11:38With a purlin roof, you also have rafters – just to make sure you don’t confuse that.
In my case, a rafter is simply removed if it’s in the way because of a roof window – that’s possible with a purlin roof.
