HVAC, plant and machine noise control in Riyadh
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.

01 / The material
What you are buying, and what it fixes in Riyadh
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 Riyadh is mostly government and corporate buildings, hotels, large developments, hospitals, schools, auditoriums.
- Heat and sealed buildings Closed up with heavy cooling all year. Plant noise has nowhere to escape and rooms stay hard and live inside.
- Inland, so plan the road leg Dammam then several hundred kilometres by road. We quote the sea leg and the inland leg separately so the programme runs on real dates.
- Very large single orders Development-scale work means the same detail repeated across many buildings. Batch consistency matters more than the figure on any one sheet.
- 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 Riyadh.
02 / The build-up
What goes where, from the structure in
-

Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Riyadh, 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.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-

Layer 2
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 Riyadh, mosques, conference halls and hotel ballrooms are tall hard volumes where intelligibility over a long reverberation tail is the whole brief.
First reflection points. Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
-

Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Riyadh, 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.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
For a Riyadh practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / In this market
What we see driving Riyadh briefs
- Heat and sealed buildings
Closed up with heavy cooling all year. Plant noise has nowhere to escape and rooms stay hard and live inside.
- Inland, so plan the road leg
Dammam then several hundred kilometres by road. We quote the sea leg and the inland leg separately so the programme runs on real dates.
- Very large single orders
Development-scale work means the same detail repeated across many buildings. Batch consistency matters more than the figure on any one sheet.
- Assembly and briefing spaces
Large halls in concrete and stone where speech stops being intelligible well before the room sounds obviously wrong.
- 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
What each space in a Riyadh project needs
-

At source
Enclosure, barrier or anti vibration mounts at the machine. Closed up with heavy cooling all year. Plant noise has nowhere to escape and rooms stay hard and live inside.

- Wood wool acoustic panels, 20 mm
- Acoustic foam and BassBloc, 100 kg per cubic metre
-

In the path
Duct lining, attenuators and lagging on the first run out of the plant. Dammam then several hundred kilometres by road. We quote the sea leg and the inland leg separately so the programme runs on real dates.

At the receiver
Only after the first two, and only for what is left. Development-scale work means the same detail repeated across many buildings. Batch consistency matters more than the figure on any one sheet.

- Acoustic foam and BassBloc, 0.85
For a Riyadh interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Durability
What the Riyadh climate rules in and rules out
Riyadh 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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Before you buy
The six errors that cost the most
-
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Riyadh job
Closed up with heavy cooling all year. Plant noise has nowhere to escape and rooms stay hard and live inside.
05 / Supply
Getting it to Riyadh, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Dammam, then road inland to Riyadh |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Dammam, then road |
| 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, not after.

Questions from Riyadh projects
What makes HVAC, plant and machine noise control different in Riyadh?
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. Dammam then several hundred kilometres by road. We quote the sea leg and the inland leg separately so the programme runs on real dates.
Where should the budget go first on a Riyadh 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 Riyadh?
No. We manufacture in India and supply into Riyadh. 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 Riyadh site?
ships from: Palwal, Haryana, India, arrives at: Dammam, then road inland to Riyadh, 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, not after.
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
Send the drawings, get a straight answer
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
