Benutzer 20230 Nov 2022 14:37What would be the approximate cost of installing 4 heat protection devices, which are already available as materials, on Velux GGU 308 roof windows â Glass dimensions: width 62.6 cm (25 inches), height 117.3 cm (46 inches) â and installing 4 interior blackout blinds/roller shades on the attic windows?
Everything can be installed from the inside!
There is already a high level of medical and scientific awareness regarding the heat effects of climate change, especially concerning the unbearable heat in attic apartments during summer.
The problem with heat buildup in attic apartments is the strong greenhouse effect caused by direct solar heat through roof window glass. Solar radiation through the roof window panes is more than just uncomfortable â direct sunlight hitting the glass in the attic leads to severe overheating of the rooms. I experience this as torturous, resulting in indoor temperatures causing significant distress, making the attic often unbearably hot.
Due to high outdoor temperatures, âventing outâ trapped heat at night, even during summer, is not possible.
Attics feel like a hellish environment to me.
To avoid extreme heat in the attic, a very thorough planning by the architectural firm during the design of the multi-family house would have been necessary, which clearly was lacking. Often, the problem with wooden roof constructions is that they only store heat for a short time. Most of the heat radiation is transferred directly into the attic rooms, and the attic interior spaces heat up immediately without any time delay. Itâs like a sauna in the attic!
What can I demand from the landlord regarding heat?
There are no legal regulations defining a maximum tolerable indoor temperature in private apartments that would constitute a defect. The only relevant guidance is the Technical Rules for Workplaces ASR A3.5 "Room Temperature." A minor defect can be assumed if the heat protection does not meet the state of the art at the time the building was constructed. If, therefore, the temperature in an attic apartment frequently rises above 30°C to 38°C (86°F to 100°F) during hot summer days, the comfort threshold of 20°C to at most 25°C (68°F to 77°F) is clearly and significantly exceeded. âThe roof surface and attic windows form a system and must be considered as one.â "If two poorly insulated components, the roof and the attic window, are involved, improving only one part likely has no significant effect." There are sun protection solutions for windows that can be easily installed from inside or outside with just a few screws. Interior sun protection such as awnings, blinds, or fabric covers can reportedly block a large part of the heat, but it is considered âmuch more efficient if shutters or awnings are mounted on the outside of the window so that the heat does not enter the room at all.â
I have initially decided on the solution described above, but unfortunately, due to serious illness, I am now on crutches and unable to install it myself.
Thank you very much for any advice
