Can somebody please tell me what this means? The following pictures are of a wall in the garage. Behind this wall is kitchen cabinets on the inside. No sink or over in this area. Behind the area is also part of the basement wall (the width od the truss). Basically the paint and the drywall paper are very brittle in this one area. There does not seam to be any moisture present. This garage gets very warm in the summer. There is about a 30 degree temperature between the garage and the uninsulated wall in the basement. I haven’t seen this before and was wondering if somebody has and can explain what this means. I originally thought WDI, but no evidence of them. Thanks in advance for your help.
