School and classroom acoustics in Montreal
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet. 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.
- Classroom RT
- A number, set against room volume, achieved mostly at the ceiling.
- Corridor spill
- Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
- Halls and gyms
- Dual use rooms carrying speech, music and sport, where durability decides the product.

01 / The product
What this is, and what it changes in a Montreal room
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet.
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.
Work reaching us from Montreal is mostly plex and condo housing, studios and rehearsal rooms, offices, restaurants, schools, clinics.
- Plex floors pass everything Stacked flats with timber joists send footfall and speech straight down. A resilient layer under the new floor does more than any ceiling treatment below it.
- A city that makes a lot of noise on purpose Rehearsal rooms, studios and practice spaces in residential buildings are normal here. Isolation is what keeps them viable, not absorption.
- The port is in the city Containers come up the St Lawrence and land in Montreal itself, which keeps the road leg short and the landed cost predictable.
- Classroom RT A number, set against room volume, achieved mostly at the ceiling.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for school acoustics are on the main product page. This page covers what that means for a project in Montreal.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Montreal, 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.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Montreal, community centres, school gymnasiums and church halls carry speech, music and sport in the same hard volume.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Montreal, 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.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
For a Montreal 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 the buildings in Montreal do to the specification
- Plex floors pass everything
Stacked flats with timber joists send footfall and speech straight down. A resilient layer under the new floor does more than any ceiling treatment below it.
- A city that makes a lot of noise on purpose
Rehearsal rooms, studios and practice spaces in residential buildings are normal here. Isolation is what keeps them viable, not absorption.
- The port is in the city
Containers come up the St Lawrence and land in Montreal itself, which keeps the road leg short and the landed cost predictable.
- Long sealed winters
Buildings close up for months and mechanical systems run hard. Noise stops escaping and accumulates inside instead.
- Assembly and performance rooms
Community centres, school gymnasiums and church halls carry speech, music and sport in the same hard volume.
- School and campus buildings
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.
04 / Room by room
What each space in a Montreal project needs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Stacked flats with timber joists send footfall and speech straight down. A resilient layer under the new floor does more than any ceiling treatment below it.
- Wood wool acoustic panels, 1200 x 600 mm
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. Rehearsal rooms, studios and practice spaces in residential buildings are normal here. Isolation is what keeps them viable, not absorption.
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic panels, ASTM C423
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Containers come up the St Lawrence and land in Montreal itself, which keeps the road leg short and the landed cost predictable.
- 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
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
Durability in Montreal, before acoustics is discussed
Montreal 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.
On a Montreal job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

What we watch go wrong on jobs like this
-
Panels at child height where they get damaged
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating one classroom and leaving the corridor
Small on the drawing, expensive on site, and almost always found after handover.
-
Choosing a product that cannot take a football
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Treating it as a generic Montreal job
Stacked flats with timber joists send footfall and speech straight down. A resilient layer under the new floor does more than any ceiling treatment below it.
05 / Supply
Getting it to Montreal, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Port of Montreal, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Port of Montreal |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.

Questions from Montreal projects
What makes school and classroom acoustics different in Montreal?
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. Stacked flats with timber joists send footfall and speech straight down. A resilient layer under the new floor does more than any ceiling treatment below it.
Where should the budget go first on a Montreal project?
Classroom RT. A number, set against room volume, achieved mostly at the ceiling. Corridor spill. Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
Do you have an office or installation team in Montreal?
No. We manufacture in India and supply into Montreal. 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 Montreal site?
ships from: Palwal, Haryana, India, arrives at: Port of Montreal, then a short road run to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
What goes wrong most often on this kind of project?
Panels at child height where they get damaged. Treating one classroom and leaving the corridor.
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
Drawings in, BOQ and a delivered date out
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.
