Fire Rated Drywall
A layer of building paper will prevent wood expansion and contraction thus preventing cracks. According to the local building codes, it is best to use two layers of building papers for stucco and masonry applications. This is because building paper is easily damaged during the construction process. Aside from the walls, it can also be used for lining floors during the construction process.
Other common uses include
Roof sheathing during repairs: When carrying out repairs, it can be placed under the shingles for water and heat protection. It is easy and quick to install on roofs since it comes in rolls.
Making a room warm: Building paper traps heat and thus, can be used to keep the garage and storage room warm. If you have a tree house you can insulate it with the paper so that your children don’t get cold as they play in it during winter.
