Questions regarding the sealing at the bottom of the self-controlled cabinet.
Thread Content
Control cabinets generally need to be sealed; what materials are usually used for this? I’m not sure if there are any corresponding standards.
There is specialized expansion foam that can handle even large holes.
Expansive foam – works well, and it’s also easy to disassemble later on
Expanded foam is better – it provides good sealing, is easy to modify, and helps keep mice away
How big of a hole can there be under the cabinet? Under standard cabinets, there are cable openings through which cables can be passed; the remaining gaps are not very large, and explosion-proof putty is usually sufficient to fill them.
It was found that for large holes, it’s best to cover them first with aluminum-plastic panels, as these are easy to cut; after that, foam agent can be used, and it seems that rats might bite the clay.
