Living in New York City means dealing with noise in a small space. Many renters use temporary walls to divide their apartments — a bedroom for a roommate, a home office, a nursery. These walls create real separation, but a standard wall doesn’t fully block sound on its own. If quiet matters to you, soundproofing is worth understanding before you book your install.
A pressurized or flex wall stays in place using tension against your floor and ceiling — it isn’t directly attached the way a permanent wall is. That’s what makes it removable and damage-free, but it also means sound has an easier path around it than it would with real construction. A standard wall dampens some noise, but it isn’t built for full acoustic isolation on its own.
Soundproofing isn’t something you add on top of a finished wall — it’s built into the panel during installation. The crew adds acoustic insulation, typically mineral wool or dense foam, inside the wall cavity before the surface is finished. Because it’s inside the panel, the wall looks identical from either side; there’s no visible sign the upgrade was added.
This upgrade adds $350 to the cost of your wall. Since it has to be built in from the start, request it when you book your quote rather than trying to add it after the wall is already up.
Added insulation significantly reduces noise and makes daily activity and normal conversation much less noticeable, but it won’t match the isolation of poured concrete or a fully framed permanent wall. If you need studio-grade sound isolation for something like music production, that’s a more specialized need than a residential temporary wall is built for.
You’ll find plenty of advice online about layering foam panels, hanging curtains, or sealing gaps with caulk on an existing wall. These can take the edge off minor noise, but they don’t come close to insulation built into the wall itself during installation — and none of them address the core issue, which is that the wall’s construction, not its surface, determines how much sound gets through. If soundproofing matters to you, it’s worth doing right from the start rather than layering fixes on afterward.

It’s much more effective when built in from the start, since the insulation goes inside the wall cavity during construction. If your wall is already up, call us to discuss options — but requesting it at booking gets the best result.
Soundproofing adds $350 to the cost of your wall. A standard pressurized or flex wall starts at $2,250, so a soundproofed wall starts at $2,600.
If noise matters to your situation — a roommate split, a home office, a nursery, or just wanting real quiet — soundproofing is a straightforward, one-time addition at the time of installation. Call (646) 453-4443 for a free same-day quote and ask about soundproofing when you book.
