Hello everyone,
I have searched through the posts diligently but unfortunately couldn’t find an answer that fits my situation. 🙁
We have built an additional room onto the garage that is adjacent to our house. The garage’s exterior walls consist of 11.5cm (4.5 inches) facing bricks – 2cm (0.8 inches) air gap – 17.5cm (7 inches) concrete blocks.
The added room shares one long wall with the house (17.5cm (7 inches) Poroton bricks of the house’s exterior wall – 16cm (6.3 inches) mineral wool – 2cm (0.8 inches) air gap – 11.5cm (4.5 inches) concrete blocks of the additional room wall). I’ve attached a sketch.
Except for the southern exterior wall of the additional room, which is the 17.5cm (7 inches) concrete block exterior wall of the garage itself, all walls are 11.5cm (4.5 inches) concrete blocks.
The roof currently consists of an EPDM membrane on top, boarding underneath, and then spruce beams.
My goal for the additional room is to reliably prevent freezing in winter and extreme heat in summer. It will be used to store clothes and canned goods.
My questions:
1. Is roof insulation with 16cm (6.3 inches) mineral wool sufficient for this?
2. If not, which material would you recommend for interior insulation of the walls?
Exterior insulation is unfortunately not an option here. If wall insulation is necessary to achieve my goals, it’s probably just a planning mistake... =(
Many, many thanks!
