Hello everyone,
I wanted to ask for your ideas or experiences with the following unusual issue.
In our newly built single-family home, we installed a Dolle attic ladder to an unheated pitched attic space. During the heating season, I noticed moisture collecting on the sides of the hatch cover. I thought, aha – cold and warm air are meeting – a leak. I reported this directly to the carpenter, who checked the seals on the frame; everything was fine. However, on the hatch cover itself, he noticed it was warped. It was bowed upward in the middle and downward toward the corners – like a banana. Not extremely obvious visually, but you can see it if you look from the right angle and follow the edges.
So the hatch cover was replaced with a new one. A few days later, the same phenomenon occurred, with the cover warping the same way. The carpenter was puzzled; they hadn’t encountered this problem before. An inquiry was made to Dolle and it is still unresolved.
Meanwhile, the old cover, which is stored at the carpenter’s workshop, has warped back and is now straight again.
Has anyone else experienced this problem? Do you have any ideas about what might be causing it?
