ᐅ Poor insulation. Where to start?

We had the same problem. We live in an older building, and our landlord is reluctant to renovate all the "critical" areas for financial reasons, so that energy costs aren’t literally being thrown out the window every year. In our case, the main issue is the windows—no double glazing, porous seals, etc.

For now, we have managed by using sealing tape like Tesa-Moll (these are adhesive sealing strips that can be easily applied afterwards to the window frames) and also placed insulating wallpaper/insulation boards behind the radiator (these are insulating rolls with a thin aluminum layer).

The first and most cost-effective step is to ensure adequate thermal insulation. However, it is often the case that homeowners install insulation on the interior side of the house, not realizing that this leads to 95% of thermal problem areas, condensation, and mold growth. Therefore, insulation should always be applied to the exterior surfaces of the house.

Hello!
We are experiencing the same problem; it is even warmer outside than inside the apartment, despite the heating being turned up. We have already considered contacting our landlord, but what can you say in such a situation?
Best regards

I hope this is the right place for my question.

We moved into this apartment in the summer, and everything was perfect then. But now, in the colder season when the heating is on, the apartment remains relatively cool despite the heater being turned up all the way. It’s probably not properly insulated. Is there anything that can be done later on to improve the situation? At least to make it a bit better?
Maybe someone has some ideas?

Thank you.

…it could also simply be because the circulation pumps have stalled after sitting unused over the summer, which prevents hot water from reaching the apartment’s heating circuit, or if radiators are present, there might be air trapped in the pipes or in the radiators themselves!

Radiators can be bled by yourself, and the pump can be checked by a heating technician. They can also check whether the system has sufficient water pressure!

It is also important to pay attention to the room layout. I know this might sound a bit like nitpicking, but sometimes people unintentionally block the space in front of the radiators—sometimes even with drying racks, tables, chairs, etc. This is often a cause of poor heating performance.
