Glass partitions opened up the modern office and the modern loft. Light moves through them; offices feel bigger; teams stay visible. We install single-glazed partitions for fast office build-outs, double-glazed acoustic partitions where sound matters, frosted bands for privacy at sitting-eye-level, and full demountable systems for tenants who want the wall to leave with them. For residential, glass partitions are a great alternative to pocket doors — kitchen-to-living-room dividers, bedroom screens, home-office walls in Manhattan studios. We can install after hours in occupied commercial spaces so the office stays operational during the day.

Partition systems we install

From single panels to full demountable walls

  • Single-Glazed

    Standard 3/8" or 1/2" tempered glass partitions. Fast install, lowest cost, perfect for visual division.

  • Double-Glazed Acoustic

    Two panes of glass with an air gap for sound dampening. STC ratings to 38+ for executive offices.

  • Frosted Privacy

    Custom frosted bands or fully frosted panels. We can do sitting-eye-level bands at any height.

  • Switchable Privacy

    PDLC film that switches from clear to frosted with a switch. For boardrooms and high-end residential.

  • Demountable Systems

    Aluminum-framed glass walls that can be moved or removed. Popular with commercial tenants in flex leases.

  • Floor-to-Ceiling

    Full-height partitions with no top track exposed. Most modern look for new office build-outs.

The experience from start to finish was top notch. If you know anything about the triangle, where it is said that you can get all three- that is a lie. With Glowglass, you get fair pricing, quality and top notch service. If you are in the market for windows, use Glowglass. I highly recommend them.

We had a great experience with Glowglass. They were on site the next day, and back to do the job the following. It was not an easy job as an o resized screen door- but they did it perfectly. We highly recommend them!

My screen door was repaired beautifully within one week . It’s a family business so they really give attention to detail, and they were communicative, very efficient and pleasant .

Partitions FAQ

What office managers and designers ask first.

  • Single-glazed vs double-glazed — which do I need?

    Single-glazed is fine for open-plan dividers, conference rooms, and any space where sound is not a priority. Double-glazed with an air gap gives you real acoustic separation — required for executive offices, therapy rooms, and any space where private conversations need to stay private.
  • How much sound does a glass partition block?

    Single-glazed partitions typically reach STC 32–35 (similar to a typical interior wall). Double-glazed acoustic partitions reach STC 38–45 depending on glass thickness and air gap. We help you spec the right system for the room.
  • Can you customize the frosted privacy bands?

    Yes — width, height, pattern, gradient. We cut frost film on-site for sitting-eye-level bands (typically 36"–60" off the floor) or fully frost panels where total privacy is needed.
  • How long does an office partition install take?

    A typical 4–6 panel office partition installs in 1–2 days. Larger build-outs with demountable systems can run 3–5 days. We schedule around your office hours where needed.
  • Are glass partitions DOB-compliant?

    Glass partitions used as interior dividers in office and residential spaces generally do not require DOB permits when they do not affect egress or fire-rated assemblies. We confirm at the estimate.
