Bubbles in Shaw vinyl sheet flooring
We have a Salem Hemisphere Travel Trailer with what the Forest River product information describes as Shaw vinyl flooring. I noticed some bubbles in the flooring near some of the heat vents. Removal of the vents exposed a very flexible flooring material that at least to me appears very similar in thickness and flexibility to rubber roofing material. Inspection of the areas around the bathroom and kitchen vents where there were bubbles showed no indication of any moisture getting to the subfloor. I later noticed some bubbles at random locations throughout the trailer. It appears that the interior walls, bed and sink cabinet were all installed after the floor was placed. When we returned from our latest trip and the heat was turned off in the trailer, all of the bubbles have disappeared and the flooring seems tight on the subfloor. Has anyone else noticed this? What if anything can/should be done?
