Pressurized wall
From Wikipedia, the free encyclopedia
Pressurized walls or temporary walls are walls built utilizing reams of 1/2" to 1" sheetrock [1](plasterboard), metal 2x3"s or 2x4's, 8' to 10' pressure jacks, taping, compound and 2-3" sheetrock screws to attach the sheetrock to the pressurized 2x4's on both the floor, ceiling and side's of the main load bearing walls, during the frame out process. The screws are used only on the 2x4 studs being utilized to prevent structural or architectural damage to the surrounding area being utilized. Hollow doors or French style doors are usually recommended to prevent weight overload or shifting of a pressurized or temporary wall. Completed walls are usually painted to color of choice and or wallpapered. Notably these type of pressure walls or room dividers have become a new phenomenon in New York City and are used to split large apartments and lofts, allowing roommates to afford privacy and or to help defray the high and rising NYC rent costs, create a home office, baby room and walk in closets.Many landlords allow construction of pressurized walls, but demand removal at the end of a lease or when moving out of the apartment or loft.
