Thermal insulation - Which drills and dowels?

Hello,

it's not time yet, but I'm already wondering how I should attach something to the [WDVS] later on.

Structure: 17.5 cm sand-lime brick wall + 18 cm [WDVS].

I understand that heavy things should be attached to the masonry behind the [WDVS] (e.g. the canopy, which is planned accordingly). However, lighter objects like the mailbox, the house number, or outdoor lamps should, according to everything I've read, be attachable to the [WDVS]. Which drill bits should I use for that? Are there special ones or is a wood drill bit enough?

Best regards,

You don't need a drill at all. There are spiral-shaped thermodowels in various sizes for this purpose that can be easily screwed into the ETICS with a cordless screwdriver and a suitable bit, usually Torx, without pre-drilling through the plaster. You can get them at any hardware store.

Now that's what I call class! Thank you!

I have now taken a look at the insulation anchors from Fischer. It is recommended to "seal the edge of the anchor after successful pre-positioning installation." How is something like that sealed?
