We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.

01 / The material

What this is, and what it changes in a Sri Lanka room

A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. It is the answer for a doorway, a stage, a partition that must move, not a substitute for a wall.

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.

  • Full height with return Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
  • Track with a seal Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
  • Double layer at a doorway Two curtains with an air gap where a single layer will not reach the target.
  • What it will not do A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet.

02 / Specification sheet

The numbers, and they do not move by city

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.

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 / In this market

What we see driving Sri Lanka briefs

  • Hospitality leads the market

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

  • 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.

  • Buying direct from the plant

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

  • The housing stock

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

  • The studio and content scene

    A growing broadcast and music sector working inside converted commercial rooms.

For a Sri Lanka practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

04 / Climate and durability

Durability in Sri Lanka, before acoustics is discussed

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.

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

05 / Route to site

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
PackingRolled and bagged with track and fixings listed separately.
Lead timeMade to size. Confirmed at quote.

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.

The same 5 piece minimum applies on export.

Any size5 pieces

Curtains are made to size, so the minimum is counted in pieces rather than area.

06 / Read this first

The things worth knowing before you place the order

  • The wrong product for the problem

    A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet. We quote the detail, not just the fabric.

  • Coverage bought instead of a target

    Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.

  • A claim of being local to Sri Lanka

    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

Sri Lanka: questions we are actually asked

Where are the soundproof curtains you supply to Sri Lanka actually made?

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.

Why would a Sri Lanka build-up differ from anywhere else?

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.

Does Sri Lanka weather shorten the life of this material?

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.

When are soundproof curtains the wrong purchase?

A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet. We quote the detail, not just the fabric.

What is the minimum order and how is it packed?

The same 5 piece minimum applies on export. Any size, 5 pieces. Curtains are made to size, so the minimum is counted in pieces rather than area. Rolled and bagged with track and fixings listed separately.
