Manufactured in India, supplied in Denver
Soundproofing materials in Denver
We manufacture soundproofing materials 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.

- One batch across the order, no blending between runs
We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / What it is
The material, and what it actually does on a Denver job
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
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.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in Denver.

02 / Data sheet
Published specification, identical wherever we ship it
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.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

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.
03 / What drives the brief
The Denver conditions that change the answer
- 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.
- 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.
- 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.
- Plant and HVAC
Packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
- The housing stock
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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Conditions
Why the climate in Denver changes the material, not the target
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.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
05 / Logistics
Getting it to Denver, with real dates
| 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 | Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.
06 / Straight talk
What we will tell you that a reseller will not
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
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.
-
Local approvals that nobody actually holds
We hold no Denver certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

The product on finished jobs
Denver: questions we are actually asked
Do you manufacture soundproofing materials in Denver?
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.
What do you look at first on a Denver enquiry?
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.
Does Denver weather shorten the life of this material?
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 quickly can material reach a site in 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.
What should you not buy soundproofing materials for?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
How is the order packed and what is the minimum?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.
