The anchors used to fix the polystyrene to the facade are in a way a thermal bridge. This is especially visible in the transitional months, when water condenses at the anchor points on the façade. Due to several freezing cycles, the colour of the façade changes at these points and is disturbing. We recommend that you use anchors with a 2 cm plate already in place. Their installation is easy with the help of a router from the anchor manufacturer. This solution is economical. The building trade will be happy to advise you.
In the following gallery you can see just the shortcomings of the implementation, which are visible only after some time and the handover of the building. It is necessary to prevent such mistakes, which is why this article was written. Take advice from the construction companies and avoid such mistakes.
These undesirable elements can also be avoided by gluing the thermal insulation in a way that is up to you. The most common method is gluing with pu foam. This saves anchors and eliminates places where unwanted thermal bridges could form. These are just at the locations of the anchors. If you already decide to anchor, I recommend using an anchoring aid, which is basically a polystyrene cutter with an anchoring jig.
