Acoustic wooden slat wall and ceiling in a premium auditorium

Manufactured in India, supplied in Seattle

Wooden slat acoustic panels in Seattle

We manufacture wooden slat acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Seattle. Made at our own plant in India and shipped into Seattle or Tacoma, so the container lands at the city it is destined for rather than crossing the country first.

01 / What it is

The material, and what it actually does on a Seattle job

Timber slats on an acoustic backing. The slats are the finish and the rhythm, the backing does the absorbing. Used where the room has to look considered rather than treated.

Work reaching us from Seattle is mostly mass timber offices, tech campuses, multifamily, studios, schools, 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.

  • Slats on felt backing The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
  • Slats on a cavity Backing plus an air gap behind moves absorption lower, which matters in music rooms.
  • Feature wall only Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
  • What it will not do A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.

Full specification

Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wooden slat panels are on the main product page. This page covers what that means for a project in Seattle.

02 / Specification

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.

  • MDFStandard. Dry interiors, general commercial
  • FR MDFFire rated. Public buildings and anywhere the specification calls for a class
  • HDHMRMoisture resistant. Humid climates and rooms that see damp

Where a consultant is already engaged on a Seattle 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

What the buildings in Seattle do to the specification

  • Mass timber is still light

    Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen.

  • Rain on the roof

    Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm.

  • Campus open plans

    Large tech floors with exposed structure and hard finishes carry speech a long way. The ceiling plane and screens have to do what the walls are not there to do.

  • The port is right here

    Containers land at Seattle or Tacoma, so there is no cross-country leg. That keeps the landed cost and the date both predictable.

  • 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.

We would rather argue about the build-up at design stage than on site. See how we support architects.

04 / Climate and durability

Durability in Seattle, before acoustics is discussed

Seattle 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.

Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.

05 / Supply

Getting it to Seattle, with real dates

Supply into Seattle
Ships fromPalwal, Haryana, India
Arrives atSeattle or Tacoma, then a short road run to site
Dispatch4 to 7 working days
FreightSea into Seattle or Tacoma
PackingBraced crates, slats supported along their length. Timber moves, so crates are kept flat and dry.
Lead timeLonger than felt. Confirmed against the pattern and substrate at quote stage.

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 Seattle or Tacoma, then a short road run to site. Air freight for samples and urgent quantities.

The same 500 sq ft minimum applies on export.

Minimum order, wooden slat acoustic panels
Any specification500 sq ft, about 46 sq m

One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order.

06 / Before you buy

What we will tell you that a reseller will not

  • The wrong product for the problem

    A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.

  • A number chased without a measurement

    If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.

  • A claim of being local to Seattle

    We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.

FAQ

Seattle: questions we are actually asked

Are these wooden slat acoustic panels made in Seattle?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Seattle as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Seattle or Tacoma, so the container lands at the city it is destined for rather than crossing the country first. You buy at factory prices with one consistent batch across the order.

What changes the specification on a Seattle job?

Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen. Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm. Those two things move the build-up far more than the panel figure does.

Is this the right material for Seattle conditions?

Seattle 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 Seattle?

ships from: Palwal, Haryana, India, arrives at: Seattle or Tacoma, 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 should you not buy wooden slat acoustic panels for?

A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.

Is there a minimum order, and how does it arrive?

The same 500 sq ft minimum applies on export. Any specification, 500 sq ft, about 46 sq m. One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order. Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry.
