Several factors account for the rising popularity of pressurized walls in the New York City area. High rental prices have forced young professionals to share small apartments. The quickest, cheapest, most practical method to create a private space for each roommate is by building a pressurized wall. One can create a separate room in less than a day. Since the walls are not pre-fabricated, each wall is customized to provide a unique solution to your space problem.

Landlords don’t object since unlike general construction, pressurized walls are not fastened by screws or bolts to the existing walls, floor and ceiling and thereby cause no damage. Even though they can be easily removed, pressurized walls are strong and sturdy. If painted the same color as the rest of the apartment, they blend in such a way that one almost can’t tell the difference between the new wall and the rest of the architecture.

Room divider walls utilize the power of pressure (like a car jack) to stay in place for long periods of time. They are sturdy enough to hang pictures and mirrors. On average, installation takes about 4 to 5 hours. Complicated installations are usually completed within a day. This is far quicker, neater and cheaper than regular remodeling.

Room divider walls are 4.75 inches in width and customized to fit your space. Accessories such as various types of doors, windows for light and ventilation, and insulation for more privacy, are available.

It's easy to get started.  Most room divider walls can be ordered and installed within 3 weeks and at certain times during the year, within a week.
For those unable to renovate with general construction, pressurized walls are the quickest, cheapest and most beautiful solution.
