That may be. But we are talking about a new building constructed according to the Energy Saving Ordinance, where fluctuations are significantly lower than in old buildings. But surely it doesn't hurt to do it right from the start :)

Oh, being a carpenter would always have been my dream job.

The air humidity doesn't care whether it was built according to the Energy Saving Ordinance. If a precisely working dehumidification system for summer and a humidification system for winter were not installed, then depending on the construction method (wood or stone), relative humidities fluctuate between 25-80% throughout the year. Wood is stable at 55% RH, and every step in either direction leads to dimensional changes.

So with controlled residential ventilation we have 40% in winter and max. 60% in summer in the house. Without, no idea.

Purely physically, a maximum of 60% RH in summer can actually only be achieved with dehumidification. If only a few materials with buffering capacity have been installed, then the fluctuations are even stronger. A wooden house is more inert than a stone and tile construction and can cushion more peaks. Some regions may be drier than others - but values of up to 80% RH are common here in July, August, and September.

How about Pattex silicone adhesive, for example? It has high long-term elasticity. It doesn't stick quite as well as other assembly adhesives, but it is specially designed for elastic joints.

We glued our house number sign with it. Since it was too cold the first time at 0°C (application temperature at least 5°C), it fell off again after a few hours. After the second attempt (it was significantly warmer), the adhesive set well and it is now holding tightly.
