HVAC, plant and machine noise control in Calgary
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. Forced air heating runs most of the year, so duct-borne noise and return air paths carry sound between rooms as reliably as the walls do.
- 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 / What it is
The material, and what it actually does on a Calgary job
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.
Forced air heating runs most of the year, so duct-borne noise and return air paths carry sound between rooms as reliably as the walls do.
Work reaching us from Calgary is mostly corporate offices and operations centres, condo towers, schools, clinics, home theatres.
- A long way inland Vancouver then rail across the mountains. It is a real leg with real time attached, and we build it into the date rather than quoting a port arrival.
- Operations centres run all day Rooms where people monitor, take calls and talk over each other for twelve hours need intelligibility and privacy together, not just less echo.
- Sealed against deep cold Buildings close up for months and mechanical systems work hard. Sound stops leaking out and starts building up, so absorption has to be balanced rather than maximised.
- 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 Calgary.
02 / The build-up
The build-up, layer by layer
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Calgary, forced air heating runs most of the year, so duct-borne noise and return air paths carry sound between rooms as reliably as the walls do.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
Layer 2
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 Calgary, community centres, school gymnasiums and church halls carry speech, music and sport in the same hard volume.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Calgary, school buildings run hard floors and lay-in tile with long heating seasons and sealed envelopes, so rooms stay live and mechanical noise is always present.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
Architects working in Calgary usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / In this market
What decides the build-up in Calgary
- A long way inland
Vancouver then rail across the mountains. It is a real leg with real time attached, and we build it into the date rather than quoting a port arrival.
- Operations centres run all day
Rooms where people monitor, take calls and talk over each other for twelve hours need intelligibility and privacy together, not just less echo.
- Sealed against deep cold
Buildings close up for months and mechanical systems work hard. Sound stops leaking out and starts building up, so absorption has to be balanced rather than maximised.
- Light frame residential
Condo and house construction is gypsum on studs, which passes low frequency far more easily than concrete. Added mass and decoupling do the work.
- Plant and HVAC
Forced air heating runs most of the year, so duct-borne noise and return air paths carry sound between rooms as reliably as the walls do.

At source
Enclosure, barrier or anti vibration mounts at the machine. Vancouver then rail across the mountains. It is a real leg with real time attached, and we build it into the date rather than quoting a port arrival.

In the path
Duct lining, attenuators and lagging on the first run out of the plant. Rooms where people monitor, take calls and talk over each other for twelve hours need intelligibility and privacy together, not just less echo.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic foam and BassBloc, 100 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. Buildings close up for months and mechanical systems work hard. Sound stops leaking out and starts building up, so absorption has to be balanced rather than maximised.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic foam and BassBloc, 100 to 500 Hz
- Ceiling baffles and clouds, ASTM C423
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate
Why the climate in Calgary changes the material, not the target
Calgary is cool and damp, with long heating seasons and cold external walls, and that narrows the material list before acoustics is discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The failure we design against here is condensation behind linings in older, poorly insulated stock.
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 / Worth knowing
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
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Ignoring structure borne vibration through the mounts
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating it as a generic Calgary job
Vancouver then rail across the mountains. It is a real leg with real time attached, and we build it into the date rather than quoting a port arrival.
05 / Logistics
Supply into Calgary, start to site
| Ships from | Palwal, Haryana, India |

Questions from Calgary projects
What makes HVAC, plant and machine noise control different in Calgary?
Forced air heating runs most of the year, so duct-borne noise and return air paths carry sound between rooms as reliably as the walls do. Vancouver then rail across the mountains. It is a real leg with real time attached, and we build it into the date rather than quoting a port arrival.
Where should the budget go first on a Calgary 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 Calgary?
No. We manufacture in India and supply into Calgary. 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 Calgary site?
ships from: Palwal, Haryana, India, arrives at: Vancouver, then rail and road to Calgary, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Add the sea leg to Vancouver and the rail leg inland, and plan the full window. We quote both parts separately.
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.

Drawings in, BOQ and a delivered date out
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
