Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.

01 / The product

What this material is and where it earns its place in Lucknow

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 Lucknow is mostly government and institutional buildings, colleges, hospitals, auditoriums, hotels, offices.

Independent houses and builder flats in brick and RC frame, often built floor by floor for different households, so the slab between them was never detailed as a separation.

  • 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 Lucknow.

02 / Specification

The numbers, and they do not move by city

We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.

  • 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 / On the ground

The Lucknow conditions that change the answer

  • Rooms built for listening

    Assembly halls and lecture theatres in concrete and tile defeat the speaker long before anyone calls the room echoey.

  • Heritage alongside new build

    Old buildings that cannot be altered, and new institutional blocks where the acoustics were costed out of the BOQ.

  • Medical privacy

    Consult and counselling rooms where conversations have to stay in the room. Partition and door before panel.

  • Next day from the plant

    A short run, so samples arrive quickly and freight stays cheap on large orders.

  • School and campus buildings

    Large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.

Architects working in Lucknow 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

Durability in Lucknow, before acoustics is discussed

Lucknow is hot summers, mild winters and a distinct wet season, and that narrows the sensible material list before acoustics is even discussed.

PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.

The risk we design against here is wet-season humidity behind linings.

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.

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 Lucknow 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

Lucknow: questions we are actually asked

Do you manufacture PET felt acoustic panels in Lucknow?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Lucknow as the manufacturer rather than through a dealer. Lucknow work is mostly institutional and mostly new. You buy at factory prices with one consistent batch across the order.

What decides the specification for a Lucknow project?

Assembly halls and lecture theatres in concrete and tile defeat the speaker long before anyone calls the room echoey. Old buildings that cannot be altered, and new institutional blocks where the acoustics were costed out of the BOQ. Those two things move the build-up far more than the panel figure does.

How does the Lucknow climate affect this product?

Lucknow is hot summers, mild winters and a distinct wet season. PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH. The failure we design against here is wet-season humidity behind linings.

What is the delivery time into Lucknow?

made at: Our own plant, Palwal, Haryana, reaches site in: a day, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.

When are PET felt acoustic panels the wrong purchase?
