The door was the last thing we thought about and the first thing that failed us. We had spent months getting the acoustic treatment right inside our meeting rooms — wall panels, ceiling baffles, floor underlays — and then we fitted standard glass doors and undid most of it in a single installation.
We manage a co-working and private office space in Business Bay, Dubai. Privacy between spaces is not an optional feature — it is the product. When a client in a private office can clearly hear the conversation happening in the adjacent meeting room, that is not a minor complaint. It is a reason they do not renew.
We found waseemtechnical through a referral from another commercial fit-out project in the area. What made us take the conversation seriously was that they asked about STC ratings before they asked about anything else. That is the question a specialist asks. A generic door supplier asks about size and finish.

What went wrong with the generic supplier

The original doors came from a general fit-out supplier we had used for joinery and ironmongery on the same project. They offered glass doors in the style we wanted, the lead time was workable, and the sales conversation was straightforward. None of that was the problem.
The problem became clear within a week of occupation. Sound transmission through the doors was significant. A conversation at normal speaking volume in a meeting room was audible in the adjacent corridor. A call on speaker was audible two offices away. The glass looked right but it was performing like standard float glass — because it was.
When we went back to the supplier with the issue, the response confirmed what we had suspected: they had not specified acoustic laminated glass because we had not asked for it, and they had not asked us whether acoustic performance was a requirement. For a general supplier, a glass door is a glass door. The acoustic specification is the customer’s problem to define.
We had not defined it because we did not know we needed to. That is the gap a specialist closes.

What a specialist assessment actually covers

Waseem Technical’s assessment process was different from the first conversation with the generic supplier in almost every respect. They visited the site, measured the door openings, reviewed the wall construction on either side, and asked detailed questions about how each space was being used — whether rooms were for video calls, in-person client meetings, or general team work.
From that assessment they specified a glass construction and door system appropriate to the privacy level each opening required. Not every door in the space needed the same specification — a corridor-facing door on a quiet office has different requirements from a door between two active meeting rooms — and the recommendations reflected that.
The things the assessment covered that the generic supplier never raised:
• STC rating requirements per opening. Sound Transmission Class is the measurable standard for acoustic performance. The generic supplier never mentioned it. Waseem Technical structured the entire specification around it.
• Glass construction for the required performance level. Acoustic laminated glass uses a PVB interlayer between glass panes that dampens sound transmission. The interlayer thickness and glass configuration determine the rating. This is not a detail a general supplier specifies by default.
• Frame and seal integrity. A high-performance glass unit in a poorly sealed frame performs far below its rating. The door system — frame, seals, threshold, hardware — was specified as a complete acoustic assembly, not as separate line items.
• Flanking transmission paths. Sound travels through walls, floors, and ceilings as well as through the door itself. The assessment identified two openings where the wall construction adjacent to the door frame would undermine the door’s performance without additional treatment.
What the installation delivered
Installation took three days across the affected openings. The works were sequenced to keep the majority of the space operational throughout — a practical detail that mattered given we had tenants in the building during the remediation.

The difference after installation:

• Specialist door service with a documented privacy rating. Each door installation was completed to a specified STC rating appropriate to the space it serves. We have documentation we can show prospective tenants. That is a tangible thing we could not offer before.
• Speech privacy between adjacent spaces. A normal conversation in a meeting room is no longer intelligible in the corridor outside it. A call on speaker in one office does not reach the next. The product we were selling — genuine privacy — now performs the way it was described.
• No complaints since installation. In the months before the remediation, acoustic complaints were the most common issue raised by tenants. Since the doors were replaced, we have not received a single one.
• The glass still performs visually. Acoustic laminated glass in the right specification is visually indistinguishable from standard glass. The openness and light transmission we wanted from a glass door is unchanged. Only the acoustic performance is different.
If you are fitting out a commercial space in Dubai where acoustic privacy between rooms is a real requirement, a generic door supplier will give you a door that looks right. A specialist will give you a door that performs. Their ACOUSTIC LAMINATED GLASS Doors SERVICES IN DUBAI cover the full scope — assessment, specification, supply, and installation as a complete acoustic system rather than individual components.

The question worth asking before any glass door specification

Ask your supplier what STC rating the door assembly will achieve in your specific wall construction. If they cannot answer that question with a number, they are not specifying an acoustic door — they are selling you a glass door and letting the acoustic performance be whatever it turns out to be.
For a co-working space, a private clinic, a law firm, a recording facility, or any commercial environment where what happens inside a room needs to stay there — that question is the difference between a fit-out that works and one that needs remediation.
We learned that the expensive way. It is a straightforward question to ask before you start.
