01 / What it is
The product, described honestly, for a Tanzania 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 Tanzania is mostly hotels and lodges, offices, places of assembly, schools, hospitals, apartments.
Concrete and block construction with hard floors, in apartment blocks and compounds close to each other.
- 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 Tanzania.
02 / Specification sheet
One specification sheet, the same in every market
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.
- 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

Where a consultant is already engaged on a Tanzania project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / In this market
What we see driving Tanzania briefs
- Hot and humid on the coast
PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag quickly.
- A short sea leg from India
Western India to Dar es Salaam is one of the quicker runs we operate, which makes modest and repeat consignments practical.
- A gateway, not just a destination
Material often continues inland to neighbouring countries. Tell us if that is happening and we pack for the second leg.
- Lodges and hospitality
Hotel and lodge work where guest room isolation and function space acoustics are the two recurring briefs.
- School and campus buildings
Classrooms are hard and naturally ventilated with large class sizes and open circulation.
Architects working in Tanzania usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Climate and durability
The Tanzania climate decides the material list
Tanzania 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.
For a Tanzania interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Route to site
What the route into Tanzania actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Dar es Salaam, then road onward |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Dar es Salaam |
| Packing | Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote. |
| Lead time | 4 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 Dar es Salaam, then road onward to site or across the border. 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.
| 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.
06 / Straight talk
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.
-
Local approvals that nobody actually holds
We hold no Tanzania certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Tanzania: questions we are actually asked
Do you manufacture PET felt acoustic panels in Tanzania?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Tanzania as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Dar es Salaam, a short and frequently served run from western India. You buy at factory prices with one consistent batch across the order.
Why would a Tanzania build-up differ from anywhere else?
Western India to Dar es Salaam is one of the quicker runs we operate, which makes modest and repeat consignments practical. Material often continues inland to neighbouring countries. Tell us if that is happening and we pack for the second leg. Those two things move the build-up far more than the panel figure does.
How does the Tanzania climate affect this product?
Tanzania 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 Tanzania?
ships from: Palwal, Haryana, India, arrives at: Dar es Salaam, then road onward, 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.
How is the order packed and what is the minimum?
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.
