ᐅ Window Installation – Looking for Help and Ideas

Hello,

Could you maybe share some tips on how your windows are designed? Currently, the windows in the old building are being replaced, but neither interior nor exterior window sills or the window recess depth were considered by the previous owner. This means the window is basically flush with the wall, with only about 1–2cm (less than 1 inch) of depth.

I had already gotten used to this, but when you’re doing renovations, you naturally wonder if it could be done better, especially since it’s supposed to last longer.

Currently, it looks like in the picture.

The window is in the kitchen and sits about 10cm (4 inches) above the countertop. Do you think this height is okay? Or what would you improve overall?

I should have mentioned that it is a prefabricated house.

Older house, prefabricated house: ? ? ? ? ?

I don't think it's an older house in the traditional sense. An older house usually means built before 1948, in which case a prefabricated house would be b) rare and a) hardly worth installing new windows, or c) probably not allowed to replace windows without heritage preservation approval. The windows in the picture also don’t yet look like they need replacement. Isn’t it a bit early for April Fools’ jokes? What do you think?

I wouldn’t consider it an old building; old buildings would date back before 1948. In that case, a prefabricated house b) would be rare and a) hardly worth installing new windows, or c) probably not possible without heritage conservation approval. However, the windows in the picture don’t look ready to be replaced yet. It’s a bit early for April Fools’ jokes, don’t you think?

The picture is just an example; currently, I only have a hole in the wall. So I’m asking before the window is installed.

Old building means a 1972 prefabricated house.

I would add insulation first; that way, you’ll also have space for window sills.
9cm (3.5 inches) of insulation... good luck heating the place.

You do understand how a prefabricated house is constructed, right? The wall cavities are insulated, and according to the energy performance certificate, my primary energy demand is 93 kWh. Annual heating oil costs including domestic hot water total around €800, so I can’t really complain.

Yes, and if the infill panels are basically not insulated, you should just add something on the outside.
Is heating oil really that cheap right now? Or is the house only 50 m² (540 ft²)? Otherwise, I find it hard to imagine.

Not at the moment, but based on the values, I thought the current insulation thickness was sufficient. I’m only working on one room and didn’t want to do a complete overhaul. The cabin won’t be standing in 10 years anyway.
