Why attic panel garage. A ceiling attic access door provides easy access for maintenance repairs or other purposes. Does a garage attic need to be insulated. Some very old homes have attic access only through a removable vent panel at a gable end wall of the roof. We have these specialty doors at access doors and panels designed to be installed easily.
Not sure why we did this probably because we knew that creating the small attic access door was easy. Most garages have a ceiling secured to the bottom chord of the roof trusses or rafters and that has to be 1 2 drywall also when the attic is continuous over the garage. We had the contractors just drywall over the original attic access panel. When we started renovating the kitchen we had asbestos removal and drywall installed.
The wall and ceiling between an attached garage and the house living area is required to be minimum 1 2 drywall. Why is there no attic access hatch in the house. That is why residential and non residential buildings need to follow regular attic cleaning schedules. So anyways we had an attic access panel when we moved in.
