Hello everyone!
Wonderful that this forum exists. So I'll just get started right away .
I have a wooden garage that is free-standing on every side. The garage is built as shown in the sketch. That means on the left there is a small annex directly connected to the garage room – thus making the 'original garage' larger. On top of that is a gable roof .... see sketch. The roof is directly connected to the garage room – so it is 'one big room' – there is no separate 'attic' dividing the garage into two rooms!
The goal: I want to be able to work in my garage in winter/autumn without freezing . That means the garage needs to be insulated. That's not a problem – I was thinking of using 100mm thick Neopor. The heat source would be a medium-sized stove with chamotte bricks.
Now the question:
Option 1: I leave the garage exactly as it is and insulate it completely: exterior walls + roof. Now I have an 84m³ room that I have to heat – the heat rises first under the roof and then slowly comes down.
Option 2: I build a classic attic floor – i.e. a floor that separates the roof from the garage room and then insulate this normally – so you would only have a 73.5m³ room to heat.
-> It is clear that option 2 is better in terms of energy! The air does not first 'pointlessly' collect under the roof + it gets warm faster -> But option 2 is also much more expensive because the attic floor has to be built first. So, with option 1, can you just say "Yeah, you just have to wait 5 minutes longer until it gets warm" or is the difference really significant? That means, is the installation of the attic floor worth it?
I am very grateful for any tips and especially experience!
