HVAC, plant and machine noise control in Medina
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space. Cooling runs year round at high load, so chillers, AHUs and large duct runs are constant sources. Plant room lining and duct attenuation carry most of the result.
- At source
- Enclosure, barrier or anti vibration mounts at the machine.
- In the path
- Duct lining, attenuators and lagging on the first run out of the plant.
- At the receiver
- Only after the first two, and only for what is left.

The product, described honestly, for a Medina brief
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space.
Cooling runs year round at high load, so chillers, AHUs and large duct runs are constant sources. Plant room lining and duct attenuation carry most of the result.
Work reaching us from Medina is mostly new hotels, residential towers, assembly and function halls, offices, clinics, schools.
- Decisions still on paper On a new build the isolation layer costs a fraction of what it costs to retrofit. Send the drawings early and we will mark where the build-up will fail before it is built.
- Large halls, long reverberation Big assembly spaces in concrete and stone hold sound for a long time. Absorption has to be placed where it recovers intelligibility, not spread evenly to hit a number.
- Long programmes need consistent stock A tower fitted out over many months needs the last delivery to match the first. We hold batch consistency and tell you if a colour is changing.
- At source Enclosure, barrier or anti vibration mounts at the machine.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for HVAC and plant noise control are on the main product page. This page covers what that means for a project in Medina.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Medina, cooling runs year round at high load, so chillers, AHUs and large duct runs are constant sources. Plant room lining and duct attenuation carry most of the result.
Independent leaf. A second wall that does not touch the first. Nothing else comes close for the money.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Medina, mosques, conference halls and hotel ballrooms are tall hard volumes where intelligibility over a long reverberation tail is the whole brief.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 3
Acoustic foam and BassBloc
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing. In Medina, new school and university buildings are large, hard and highly glazed. Lecture theatres and sports halls are the spaces that fail first, and ceiling absorption is the practical fix.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
For a Medina practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / On the ground
What we see driving Medina briefs
- Decisions still on paper
On a new build the isolation layer costs a fraction of what it costs to retrofit. Send the drawings early and we will mark where the build-up will fail before it is built.
- Large halls, long reverberation
Big assembly spaces in concrete and stone hold sound for a long time. Absorption has to be placed where it recovers intelligibility, not spread evenly to hit a number.
- Long programmes need consistent stock
A tower fitted out over many months needs the last delivery to match the first. We hold batch consistency and tell you if a colour is changing.
- Quiet city, loud buildings
The noise that reaches guests here is rarely from the street. It is the corridor, the next room and the plant, which is a detailing problem rather than a facade problem.
- Plant and HVAC
Cooling runs year round at high load, so chillers, AHUs and large duct runs are constant sources. Plant room lining and duct attenuation carry most of the result.
04 / Room by room
Space by space, for Medina briefs

In the path
Duct lining, attenuators and lagging on the first run out of the plant. Big assembly spaces in concrete and stone hold sound for a long time. Absorption has to be placed where it recovers intelligibility, not spread evenly to hit a number.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Wood wool acoustic panels, 400 kg per cubic metre
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
At the receiver
Only after the first two, and only for what is left. A tower fitted out over many months needs the last delivery to match the first. We hold batch consistency and tell you if a colour is changing.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Climate
Why the climate in Medina changes the material, not the target
Medina is hot and dry for most of the year, with dust and high daytime surface temperatures, and that narrows the material list before acoustics is discussed.
Dust is the enemy of open-cell products. PET felt does not shed, does not hold dust in the way fabric-wrapped glass wool does, and wipes down. Timber needs a stable indoor RH or it moves.
The failure we design against here is dust ingress and thermal movement in long runs.
Where a consultant is already engaged on a Medina project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Straight talk
What we watch go wrong on jobs like this
-
Absorption on the office wall for a plant room problem
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
Lagging a duct that is carrying the noise as breakout from the fan
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Ignoring structure borne vibration through the mounts
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Medina job
On a new build the isolation layer costs a fraction of what it costs to retrofit. Send the drawings early and we will mark where the build-up will fail before it is built.
05 / Route to site
How material reaches a Medina site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Jeddah or Yanbu, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Jeddah or Yanbu |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order.
Sea freight into Jeddah or Yanbu, then road to site. Air freight for samples and urgent quantities.
Questions from Medina projects
What makes HVAC, plant and machine noise control different in Medina?
Cooling runs year round at high load, so chillers, AHUs and large duct runs are constant sources. Plant room lining and duct attenuation carry most of the result. On a new build the isolation layer costs a fraction of what it costs to retrofit. Send the drawings early and we will mark where the build-up will fail before it is built.
Where should the budget go first on a Medina project?
At source. Enclosure, barrier or anti vibration mounts at the machine. In the path. Duct lining, attenuators and lagging on the first run out of the plant.
Do you have an office or installation team in Medina?
No. We manufacture in India and supply into Medina. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Medina site?
ships from: Palwal, Haryana, India, arrives at: Jeddah or Yanbu, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order.
What goes wrong most often on this kind of project?
Absorption on the office wall for a plant room problem. Lagging a duct that is carrying the noise as breakout from the fan.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
Next step
Tell us the room, we will tell you the build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
