Glass Partitions & Doors for Offices

Office glass partitions are single- or double-glazed toughened screens, frameless doors and acoustic glazed rooms that divide a floor while keeping it open. Single glazing gives visual separation; rooms needing confidentiality need double glazing with offset thicknesses and a sealed head, base and plenum, because sound mostly leaks around the glass rather than through it.

What we deliver

Glazed office partitions, frameless doors and acoustic glazed rooms — specified around the privacy each room actually needs rather than a single default applied across the floor.

Glass is what makes a modern office feel open while still being divided. It is also where acoustic expectations quietly break: clients specify glass for daylight and openness, then expect the confidentiality of a solid wall.

Where projects go wrong

  • Glass specified for openness, judged on privacy. Decide per room what it actually has to do before choosing the build-up.
  • Perimeter sealing ignored. Sound over the head track through the shared plenum defeats even good glazing.
  • Hardware chosen after the glass is ordered. Cut-outs are made before toughening; a late change means new glass.
  • Manifestation forgotten. Full-height clear glass in a circulation route is a walk-into hazard and needs visible marking.
  • Floor spring pocket formed badly. The most common cause of frameless doors that sag, bind or stop closing.

Why Hagerstone

Glass expertise across the business. The same organisation delivers facade glazing, structural silicone and frameless entrance doors, so interior glazing is detailed by people who work with glass at building scale — not treated as a joinery afterthought.

In-house fabrication with CNC-grade machinery, under ISO 9001 / 14001 / 45001 and 79+ quality checkpoints.

Standards referenced

Architectural safety glass, including where toughened or laminated is required, under IS 2553 (Part 1). Means of egress and door requirements under NBC 2016, Part 4.

Standards referenced

  • IS 2553 (Part 1) — Safety glass — architectural (Bureau of Indian Standards)

Frequently asked

Single glazing is fine for visual separation — a room you can see into but do not need confidentiality in. Double glazing, with an air gap and ideally offset glass thicknesses, is what you need for a room where conversations must not carry. The mistake is specifying single glazing for an MD cabin or an HR room and then being surprised that people outside can follow the conversation.

Yes for office partitions and doors. IS 2553 governs where safety glass is required, and any full-height glazed screen or door in a circulation area falls squarely in it. Frameless doors are typically 12mm toughened, with all holes and cut-outs made before toughening — which is why hardware has to be finalised before the glass is ordered.

Almost always the perimeter, not the glass. Sound goes over the head track into the shared ceiling plenum, under the floor, or through an unsealed junction. A double-glazed screen with an open plenum above it performs worse than a well-sealed single-glazed one. The detailing at head, base and jamb decides the result.
