Morel Acudamp MAT 227.8 Review: Thicker 2.7 mm Damping for the Panels That Matter
The Morel Acudamp MAT 227.8 is a pack of eight 2.7 mm damping sheets, each 460 x 800 mm, which our listing describes as a premium triple-layer construction of adhesive, butyl and aluminium. An Australian Morel retailer lists the pack's coverage as 2.944 m². Its Indian MRP is ₹14,990, the same as the ten-sheet, 2.1 mm MAT 221.10, so the choice between them is thickness against area. It suits owners who want to put more material on the panels that matter most, such as door skins behind woofers and the floor around a subwoofer. See it on our Morel Acudamp MAT 227.8 product page.

Where the extra thickness earns its place
Damping works by adding mass and stiffness to a panel and converting its vibration into heat. For the same layer make-up, a thicker sheet puts more of that mass on every square centimetre it covers. Our listing calls this mat premium but doesn't explain any difference from the 2.1 mm sheets beyond thickness, and no mass figure is published for either, so treat the gain as likely rather than measured.
The panels that benefit most are the ones that move most. The outer door skin directly behind a woofer is the classic case, especially with a stronger component set on an amplifier. The boot floor and spare-wheel well take the full force of a subwoofer, and a rear parcel shelf can buzz along with the bass. Those are the places to spend thicker material first.
MAT 227.8, MAT 221.10 or MAT 345.5?
At ₹14,990, the MAT 221.10 gives you ten 2.1 mm sheets and 3.68 m² on retailer figures, against eight 2.7 mm sheets and 2.944 m² here. If your job is spread over many panels, the extra area helps; if it's concentrated on a few hard-working ones, the thicker sheet is the more logical pick.
The MAT 345.5 is a different kind of product: 4.5 mm and four layers, adding closed-cell butyl, in five sheets covering 1.84 m², at ₹13,990 MRP. Our listing describes it as a noise barrier as well as a damping treatment, with thermal insulation, which makes it the one to consider for floors and other areas where insulation matters as much as damping. The MAT 227.8 is listed as a noise and vibration control mat.
What owners and reviewers say about the Morel Acudamp MAT 227.8
When we checked in October 2026, OnlineCarStereo listed no reviews and Frankies Auto Electrics invited buyers to be the first to write one, and we found no forum feedback naming the MAT 227.8. The closest Indian comment is general: on Team-BHP, a member in January 2025 recommended Morel sheets bought on offer from a trusted online source for the best value, without naming a model. A HiFiVision owner named the sibling MAT 221.10 as their damping material but didn't describe the result. If you've used the MAT 227.8, we'd welcome your feedback.
Who should buy it, and who shouldn't
Buy it if you want thicker damping concentrated where it matters, behind door woofers or around a subwoofer, and prefer eight thicker sheets to ten thinner ones at the same MRP.
Skip it if you need to cover a lot of area, where the MAT 221.10 or the 15-sheet MAT 121.15 goes further, or if you're treating floors and want insulation as well, where the MAT 345.5 fits better.
Installation notes for Indian cars
A 2.7 mm sheet is stiffer to work than a 2.1 mm one, so warm it slightly and use a roller to push it into ribs and curves; any air gap under the sheet is wasted damping. On the inner door skin, keep thicker material away from trim-clip points and the window regulator so the door card still seats properly. Clean the metal of dust before fitting, as a dusty surface weakens adhesion, and remember that no working temperature range is published in the sources we read, which matters in a car parked in the summer sun. Our guide on applying sound damping properly covers the process, and VA3 Car Studio in Ghaziabad offers professional installation, including door baffles for new speakers.
Price and where to buy
The Morel Acudamp MAT 227.8 has an MRP of ₹14,990 for eight sheets. VA3 Car Studio often sells below MRP, so check today's price on the MAT 227.8 product page. Everything we sell is a genuine Morel product.
The bottom line
The Morel Acudamp MAT 227.8 trades area for thickness: eight 2.7 mm sheets of adhesive, butyl and aluminium at the same MRP as ten thinner MAT 221.10 sheets. Without published mass or loss-factor figures, the benefit of the extra thickness can't be quantified, but for concentrating treatment on door skins and subwoofer areas it is the logical Acudamp choice.
Morel Acudamp MAT 227.8 FAQ
How much area does the Morel Acudamp MAT 227.8 cover?
Frankies Auto Electrics lists 2.944 m², which is eight sheets of 460 x 800 mm. How many panels that treats depends on the car and on how much of each panel you cover.
Is the MAT 227.8 better than the MAT 221.10?
It's thicker, at 2.7 mm against 2.1 mm, but you get eight sheets instead of ten for the same MRP. Neither has published mass or loss-factor figures, so choose by the job: thickness for a few key panels, area for wider coverage.
Can I use it on the bonnet?
Morel's range includes a dedicated bonnet liner, the MAT HOOD 621, which is 6 mm thick and comes as one 1000 x 1400 mm sheet. That is the Acudamp product listed for the bonnet; the MAT 227.8 is listed for general noise and vibration control.
