Standard ASTM C423. Ask for the report for the grade you specify.

What this product does

  1. 1
    Specified by NRC

    The panel is chosen from the figure the room needs, not from the finish

  2. 2
    Three grades

    0.70, 0.85 and 0.95, tested to ASTM C423

  3. 3
    Core follows the figure

    PET, mineral wool or slat-over-felt, depending on the grade and the class

  4. 4
    Report travels with the grade

    Each grade ships with its test report, and it should be checked before order

Description

This is the specifying route rather than a single product: acoustic panels selected by the NRC the room needs, then built to reach it. The range covers NRC 0.70, 0.85 and 0.95, tested to ASTM C423, and the core can be PET polyester, mineral wool or slat-over-felt depending on the figure and the fire class.

Working this way matters because the number is a property of the room, not of the panel. A busy open office usually lands around 0.70; a conference room where speech privacy matters needs more; a studio or a hall wants the top of the range. More absorption is not automatically better either — an over-absorbed room sounds dead and makes conversation feel strange — so the question is the right amount for the use. Three variables have to line up to hit a figure: the core, the thickness, and the air gap behind the panel, which is part of the absorber rather than a fixing detail. A facing is the fourth: a sealed decorative face reflects sound no matter what the core is doing. Every grade ships with its test report, and the report is worth asking for at enquiry stage so it can be checked against the specification before the order.

Send the room type, its use and the target NRC with the enquiry, and we will come back with the assembly that reaches it rather than the panel that sounds closest.

Where it is used

Open-plan offices

Around 0.70 is usually the target on a busy floor plate

Conference and board rooms

Speech privacy needs more than a general office, so the grade goes up

Studios and rehearsal rooms

The top of the range, where the room's use sets the figure

Multi-purpose halls

The room changes use, so the grade is chosen for the hardest of them

Frequently asked

What is the minimum order?

1 × 20ft container, mixed across products where the mix suits the project. A sample box can be arranged before the first container.

Can I see a sample before ordering?

Yes. Send the product and the size you are specifying, and we will confirm the sample and the lead time for it.

Which NRC do I actually need?

It depends on the room, not on the product. A busy open office usually wants something around 0.70; a conference room where speech privacy matters wants more; a studio or a hall wants the top of the range. Tell us the room and the use and we will point at a grade rather than guess for you.

Is a higher NRC always better?

No. A very absorptive room can sound dead and make conversation feel odd. The target is the right amount of absorption for the use, which is why the room comes before the number.

Does thickness alone set the NRC?

No. Thickness and the air gap behind the panel work together, and the facing matters too — a sealed decorative face reflects sound regardless of the core. All three have to be right.

Can you supply the test report?

Yes, for the grade you specify, tested to ASTM C423. Ask for it with the enquiry so it can be checked against the project specification before the order.
