This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.

01 / What it is

The product, described honestly, for a Sri Lanka brief

A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. It absorbs mid and high frequency energy and finishes as the visible surface, so it is both the acoustic layer and the finish.

Work reaching us from Sri Lanka is mostly hotels and resorts, apartments, offices, hospitals, schools, studios.

Concrete and block construction with hard floors, in houses and new apartment towers that share slabs.

  • Direct to wall Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
  • On a 25 to 50 mm air gap The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
  • Over a porous backing Panel over mineral or PET backing where the room needs genuine low mid control.
  • What it will not do It absorbs. It does not block.

Full specification

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

02 / Specification 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.

  • EchoCore 151500 GSM. Offices, classrooms, general commercial
  • EchoPro 181800 GSM. Studios, auditoria, rooms with a written RT target
  • EchoMax 222200 GSM. High occupancy and high level spaces

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 / Local conditions

What the buildings in Sri Lanka do to the specification

  • Humid, coastal, monsoon

    Our PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.

  • A very short sea leg

    Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets.

  • Hospitality leads the market

    Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs.

  • Buying direct from the plant

    No importer margin between the factory and your site, and the person answering the technical question made the product.

  • School and campus buildings

    Classrooms are hard and naturally ventilated with large class sizes and open corridors.

If you are specifying for a Sri Lanka 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

What the Sri Lanka climate rules in and rules out

Sri Lanka is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.

Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.

The risk we design against here is mould, sagging fabric finishes and swelling in timber.

Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.

05 / Supply

Getting it to Sri Lanka, with real dates

Supply into Sri Lanka
Ships fromPalwal, Haryana, India
Arrives atColombo, then a short road run to site
Dispatch4 to 7 working days
FreightSea via Colombo
PackingPalletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
Lead time4 to 7 working days for standard colours and thicknesses. Grooved and custom colours take longer, and we say so before you order.

Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.

Sea freight into Colombo, then a short road run to site. The short transit means even modest consignments move economically. Air freight for samples.

200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use.

Minimum order, pet felt acoustic panels
Trial order200 panels, 6,400 sq ft, mixed thickness, GSM and colour
RecommendedFull container, for the best price per panel and the lowest freight per panel

A panel is 1220 x 2440 mm, which is 32 sq ft.

06 / Worth knowing

Four honest warnings before you buy

  • The wrong product for the problem

    It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.

  • 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 Sri Lanka 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.

FAQ

Sri Lanka: questions we are actually asked

Do you manufacture PET felt acoustic panels in Sri Lanka?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Sri Lanka as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Colombo. You buy at factory prices with one consistent batch across the order.

What decides the specification for a Sri Lanka project?

Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets. Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs. Those two things move the build-up far more than the panel figure does.

Will this material last in the Sri Lanka climate?

Sri Lanka is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.

What is the delivery time into Sri Lanka?

ships from: Palwal, Haryana, India, arrives at: Colombo, then a short road run to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.

Where do PET felt acoustic panels fail to help?

It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.

What is the minimum order and how is it packed?

200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container, for the best price per panel and the lowest freight per panel. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
