Hello everyone,
The first snow has arrived today in NRW. A reason to be happy? Not for me.
I bought a house built in 2013. Energy efficiency class B, 68 kWh/m² per year. According to the energy certificate, the current U-value is 0.24 W/(m²·K).
It has a gas heating system with a hot water storage tank. Underfloor heating throughout the entire house. Living area is 200 m² (2,150 sq ft). The boiler room is in the attic (but not on the side shown in the photo).
I am a complete novice when it comes to houses. I have to admit I am not really skilled at DIY. But I assumed the insulation quality would be alright.
So far, there have been no problems. However, based on the thermostats in the rooms, I noticed already in autumn that the attic is slightly colder than the rest of the house—about 1 to 2 degrees Celsius (2 to 4 degrees Fahrenheit) lower. At the time, I explained this by the fact that the attic, with its roof, effectively has one more exterior wall than the ground floor and therefore is likely a bit colder.
The previous owner apparently did some patchwork here and there... I never received any construction plans or insulation documentation...
This morning I looked at the roof and noticed we have relatively little snow on it compared to the neighboring roofs. So my question is: Could this be a sign of poor insulation quality? Do I need to do something about it?
Of course, I am a bit concerned now.
Thank you very much.
