Hello everyone, I am currently planning the installation of Ikea Metod baseboards in my kitchen, which is equipped with underfloor heating. I have some concerns about how to fix the baseboards in a way that does not affect the heat output of the underfloor heating, while ensuring the baseboards hold firmly and securely.

My detailed questions are:
- Are there specific recommendations or installation methods for underfloor heating that I should consider?
- For example, is adhesive better than screws to avoid compromising the insulation effect or heat flow?
- Do I need to maintain a gap from the wall or the floor to prevent disrupting the heat distribution?
- Are there particular materials or fasteners that are especially suitable for Metod baseboards with underfloor heating?

I would appreciate any tips from experience or guidance according to relevant standards. Thank you in advance!

Regarding the adhesive: In general, silicone or specialized construction adhesives without high insulation properties should be used. Standard all-purpose adhesives are often unsuitable. It is important that the adhesive is flexible and temperature-resistant, so it can withstand stress caused by heating without cracking.

How exactly is "heat resistant" defined? Are there official standards or tests recommending such adhesives, especially in the context of underfloor heating?

That is a very good question. I found out that adhesives are tested according to DIN EN 12878, which evaluates their impact on heat transfer in underfloor heating systems. However, many construction adhesives are not specifically certified for this application.

For Metod baseboards, you should choose an adhesive explicitly rated for underfloor heating and capable of withstanding temperatures of at least 70°C (158°F). It is also important that the adhesive layer is applied thinly to avoid reducing thermal conductivity.

Hopefully, this information helps with your selection.
