Manufactured in India, supplied in Denver
Wood wool acoustic panels in Denver
We manufacture wood wool acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Denver. Made at our own plant in India, shipped into Houston or the West Coast and trucked inland, with the road leg quoted separately so the programme runs on real dates.

01 / Start here
What you are buying, and what it fixes in Denver
Wood fibre bound into a rigid board with an open texture. Robust, paintable and used where the surface takes knocks, which is why it ends up in schools, sports halls and plant rooms.
Work reaching us from Denver is mostly multifamily apartments, offices, breweries and taprooms, schools, clinics, home theatres.
American homes are timber frame with gypsum board on both faces, so a party wall or a basement ceiling has almost no mass. Adding a second leaf with a limp membrane between does more than any amount of surface treatment.
- Direct fix Mechanically fixed to the soffit or wall. Durable and simple.
- On a cavity Mounted on battens with an air gap, which is where the low mid performance comes from.
- With a porous backing Board over mineral backing where the room needs more than the board alone gives.
- What it will not do At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wood wool panels are on the main product page. This page covers what that means for a project in Denver.
02 / Specification
The published figures, unchanged by location
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings
| Panel size | 1200 x 600 mm |

Where a consultant is already engaged on a Denver project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / On the ground
The Denver conditions that change the answer
- Light frame multifamily at volume
Thousands of units built to the same separating detail. If the detail underperforms it underperforms everywhere, which makes it worth solving on the drawing.
- Taprooms and hard rooms
Breweries and taprooms are concrete, steel and glass by design. They are loud by construction, not by accident, and the ceiling plane is usually the only place to fix it.
- No port, so plan the road leg
Everything arrives at a coast and drives in. We quote the sea leg and the road leg separately so you can see where the time goes.
- Dry air, sealed buildings
Our PET felt does not shed fibre or degrade in dry conditions, and it holds its shape in rooms that stay closed and conditioned.
- Assembly and performance rooms
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
- School and campus buildings
Public school buildings run long corridors with hard floors and lay-in tile ceilings that were chosen for cost, not for speech. Classroom reverberation and corridor spill are the two complaints, and both respond to ceiling area rather than wall panels.
If you are specifying for a Denver project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate and durability
The Denver climate decides the material list
Denver is mild summers and cold, wet winters, and that narrows the sensible material list before acoustics is even discussed.
Cold external walls and long heating seasons make condensation behind a lining the thing to design out. PET felt is unaffected by damp air.
The risk we design against here is condensation and cold bridging behind new linings.
For a Denver interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Logistics
How material reaches a Denver site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Houston or the West Coast, then road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea, then road inland |
| Packing | Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected. |
| Lead time | 4 to 7 working days for standard sizes. |
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.
Sea freight into Houston or the West Coast, then road inland to Denver. Air freight for samples and urgent quantities.
The same 500 sq ft minimum applies on export.
| Any finish | 500 sq ft, about 46 sq m |
|---|
A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels.
06 / Worth knowing
Where this goes wrong, said plainly
-
The wrong product for the problem
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.

Suppliers who imply a Denver presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Denver: questions we are actually asked
Where are the wood wool acoustic panels you supply to Denver actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Denver as the manufacturer rather than through a dealer. Made at our own plant in India, shipped into Houston or the West Coast and trucked inland, with the road leg quoted separately so the programme runs on real dates. You buy at factory prices with one consistent batch across the order.
Why would a Denver build-up differ from anywhere else?
Thousands of units built to the same separating detail. If the detail underperforms it underperforms everywhere, which makes it worth solving on the drawing. Breweries and taprooms are concrete, steel and glass by design. They are loud by construction, not by accident, and the ceiling plane is usually the only place to fix it. Those two things move the build-up far more than the panel figure does.
Will this material last in the Denver climate?
Denver is mild summers and cold, wet winters. Cold external walls and long heating seasons make condensation behind a lining the thing to design out. PET felt is unaffected by damp air. The failure we design against here is condensation and cold bridging behind new linings.
How does an order actually travel to Denver?
ships from: Palwal, Haryana, India, arrives at: Houston or the West Coast, then road inland, 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.
When are wood wool acoustic panels the wrong purchase?
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
What is the minimum order and how is it packed?
The same 500 sq ft minimum applies on export. Any finish, 500 sq ft, about 46 sq m. A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels. Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected.
