Garage floor construction and which insulation - recommendations?

Hello everyone,

I am still preoccupied with the garage.

For the floor covering, I had imagined a coating with epoxy resin instead of tiles.

Does a screed need to be applied to the floor slab before the coating, or how should the ideal floor structure look here?

The garage will not be heated, so insulation of the floor slab or the roof should not be necessary, or am I wrong here? Does a frost guard need to be installed, and if so, what would you recommend?

Thank you very much

Regards

Steffen

No frost guard, no roof insulation. Foundation needs a frost skirt.

With epoxy resin coating, you don’t need screed in the garage. However, the concrete floor should be poured with a slight slope and must be cleaned or sanded before coating.

The concrete slope is too late. The floor slab is poured.

So, then screed after all?

Thank you very much

Well, it would still work, but then you have the risk of puddles in the garage. I think I would then put in screed.

How would you build the roof?

With an underlay membrane (which sd-value?) or with a full sheathing and bitumen torch-on membrane?

As roofing, trapezoidal sheet metal or Prefa is planned (probably trapezoidal because it is more cost-effective).

How would you realize this best?

No one has an opinion on the roof structure?

How should the whole thing be done for an uninsulated garage?
