    You can cut with a knife, but with a vacuum cleaner at hand because there will be a lot of polystyrene balls.
    You can cut with resistance wire aesthetically and conveniently, but watch out for fumes.
    Glue for gluing polystyrene is called ... Glue for polystyrene, or Tytan probably has some foam adhesives on offer.

    Cut the polystyrene with hot wire connected to a power supply :)

    Well, this is a special flexible seal:

    You don't even know how much I regret now that I didn't put 4x as much for a sandwich panel; /

    And what do you think about pouring self-leveling concrete inside about 15-20mm on the whole? Not only will it even out the floor (it's not perfect), it will also raise the interior and the problem with water pouring in will disappear.

    You might as well spill an industrial floor, it's non-slip and provides some kind of thermal insulation, but it's all about costs.
    The self-leveling screed is not the cheapest, and in such a small area, it is not so difficult to make a regular screed evenly.

    And if I made an ordinary 2cm spout inside, there won't be any problems with cracking etc?
    @U.P.
    I do not need the sewer, if I want to change the oil, I go to my neighbor. In addition, the screed is already, properly rubbed and poured with 22-25 cm of concrete b25 pear. Not for handicap.

    Remember once in a lifetime: the minimum thickness of the concrete screed is 7 cm.

    I don't think we understood each other ;) . The garage is already standing, on a concrete slab that was poured last year, 22-25cm b25. A week ago, I put up a garage and I have a problem with water getting in when the sheet-concrete joint is made. I want to pour a 2 cm layer from the inside to seal the garage (on the spout) ...

    In the tin plates, right on the metal sheet inside the garage, a groove is made from a patch sunk in the screed 3x3cm or 4x4 cm and if something gets into it, it will flow down this groove
    The second option is to raise the garage and give silicone or some other roofing sealant.

    The sealant has passed the test. In addition, from the bottom, as you can see in the photos, I injected polyurethane foam and cut off the excess flush with the profile. It is sealed and insulated at the same time.

    The foam will oxidize after some time and will scatter if it is not protected from the weather.

    Polyurethane foam is soaking up water - will it come into contact with uninsulated concrete or with moisture?

    The foam is on the inside, behind a sealed sheet. Even so, after all-day rainfall, the water goes inside. However, I will have to pour a 1.5-2 cm layer of concrete inside ...

    It's been a few years, but I didn't finally insulate the garage then ... until now. Yesterday I started to insulate with 40mm polystyrene, I am planning another 20mm layer to close with the poles (60x60x3mm). A regular GK board will probably go for all of this. Chinese webasto is used for heating and even without insulation it was able to heat up the interior of the garage.

Topic summary

The discussion revolves around insulating a 6x5m tin garage using polystyrene, addressing concerns about condensation, sealing, and insulation thickness. Users suggest using a vapor barrier and mineral wool as alternatives to polystyrene due to moisture absorption issues. The proposed insulation scheme includes a trapezoidal sheet, a vapor barrier, and polystyrene, with recommendations for maintaining an air gap to prevent condensation. The importance of sealing the connection between the concrete floor and the sheet metal is emphasized, with suggestions for using flexible sealants and polyurethane foam. Users also discuss the need for proper ventilation and the potential use of a wood stove for heating during winter. The conversation highlights the necessity of careful planning to ensure long-lasting insulation and sealing solutions.
