Soundproofing materials in San Francisco
We manufacture soundproofing materials at our own plant at Palwal in Haryana, India, and supply them into San Francisco. Made at our own plant in India and shipped into Oakland, across the bay, so the road leg to site is short.

- One batch across the order, no blending between runs
We make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.
01 / What it is
The material, and what it actually does on a San Francisco 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 San Francisco is mostly victorian conversions, tech offices, apartments, studios, restaurants, clinics.
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 San Francisco.

02 / Data sheet
The numbers, and they do not move by city
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- 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 / On the ground
What decides the build-up in San Francisco
- Timber Victorians
Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down.
- Depth costs real money
At local rates a wall growing into the room is a significant number. A dense thin membrane usually beats a thicker framed build-up on total cost.
- Designed to move
Seismic detailing requires junctions that stay flexible, so the acoustic layer must not stiffen across them.
- Oakland is close
A short road leg after the port keeps landed cost and timing predictable.
- 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.
If you are specifying for a San Francisco project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate
What the San Francisco climate rules in and rules out
San Francisco 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 / Route to site
What the route into San Francisco actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Oakland, then a short road run across the bay |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Oakland |
| 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.

The things worth knowing before you place the order
-
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.
-
Suppliers who imply a San Francisco 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.

How it looks once it is installed
San Francisco: questions we are actually asked
Where are the soundproofing materials you supply to San Francisco actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into San Francisco as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Oakland, across the bay, so the road leg to site is short. You buy at factory prices with one consistent batch across the order.
What do you look at first on a San Francisco enquiry?
Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down. At local rates a wall growing into the room is a significant number. A dense thin membrane usually beats a thicker framed build-up on total cost. Those two things move the build-up far more than the panel figure does.
Will this material last in the San Francisco climate?
San Francisco 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 San Francisco?
ships from: Palwal, Haryana, India, arrives at: Oakland, then a short road run across the bay, 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 will soundproofing materials 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. We would rather spend the conversation on the detail than on the product.
Is there a minimum order, and how does it arrive?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.

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.
