Pressurized wall

Pressurized walls are temporary walls that are built with reams of 1/2" to 5/8" Sheet rock (plasterboard), metal 2x3's or 2x4's, or taped, plastered and compounded. After the frame-out process, 1 1/4" sheet rock screws are used to attach the drywall to the pressurized 2x4's that contact the floor, the ceiling and the sides of the property's walls. In order to prevent structural or architectural damage, only screws are used on the studs. No additional fasteners or adhesives are used to add stability to the frame work.

Generally, hollow core doors or French style doors are recommended to prevent weight overload and/or shifting of a pressurized wall. Often, completed walls are painted the same color as existing walls. Many landlords allow their tenants to construct pressurized walls as long as tenants remove the walls before they vacate the apartment. As a result, pressurized walls have become especially popular in New York City, where the high cost of real estate has led many tenants to use these walls to create an extra bedroom, a home office, or even a walk-in closet.
