Recoil DMBK Review: 9-Sheet Butyl Damping Kit and Its Sheet-Size Mismatch
The Recoil DMBK is a nine-sheet butyl damping kit at ₹9,900 MRP, with one catch: our listing gives sheets of 550 x 800 mm, while Recoil's main-site page gives 18 x 32 in (457 x 812 mm) sheets, 90 mil and 36 sq ft in total. Recoil's pages also say a roller and knife are included. It suits fitters who want a butyl mat at a lower price per sheet than the XLBK and will confirm the sheet size before relying on the total. See the DMBK listing.
Key takeaways
Our listing says nine sheets of 550 x 800 mm, about 3.96 m² in all; Recoil's main-site page says nine sheets of 18 x 32 in and 36 sq ft, about 3.34 m². The gap is 0.62 m², or about 18%.
Recoil gives 90 mil, which is 2.29 mm, within about 0.1 mm of the XLBK's 2.2 mm.
Recoil's pages say a roller and knife are included; our listing does not mention them.
At ₹9,900 MRP the kit is ₹1,100 per sheet, or about ₹2,960 per m² on Recoil's size and ₹2,500 on our listing's.
Recoil DMBK specifications
Specification | Our listing | Recoil's main-site page |
|---|---|---|
Type | Sound damping kit, butyl-based | Butyl mat, peel and place |

Sheet size | 550 x 800 mm | 18 x 32 in (457 x 812 mm) |
Total area | about 3.96 m² (42.6 sq ft), our arithmetic | 36 sq ft (3.34 m²) |
Thickness | Not listed | 90 mil (2.29 mm) |
Layers | Described as constrained-layer | Not stated; aluminium not mentioned |
Tools included | Not listed | Roller and knife |

MRP per sheet (our arithmetic) | ₹1,100 | ₹1,100 |
MRP per m² (our arithmetic) | about ₹2,500 | about ₹2,960 |
The first column is our store page. The second follows Recoil's main-site page, which is promotional. Recoil's US page repeats 90 mil, 36 sq ft and the roller and knife but gives no sheet size or count, and Recoil's damping category lists the kit as 90 mil, 36 sq ft, with roller and knife.
Which sheet size is right?
Recoil's main-site figures agree with each other: an 18 x 32 in sheet is 4 sq ft, and nine of them make the 36 sq ft that Recoil's pages give. Our listing's 550 x 800 mm is a different size, 0.44 m² a sheet and about 3.96 m² (42.6 sq ft) for nine. We cannot say which describes the kit you will receive. The Indian distributor may supply a different pack from the one Recoil's pages describe, or one source may be wrong.
As general practice, confirm the sheet size with Recoil or the distributor before ordering for a tight job, and measure a sheet and count the sheets when the kit arrives. Recoil's main-site page also lists 28.7 lb and 13 x 22.7 x 4.7 in without saying whether that is the packed kit, so we do not use those figures.
Thickness: what 90 mil means
90 mil is 2.29 mm. Recoil's page calls the mat about 1.8 times thicker than 50 mil mats, which is simple division (90 / 50). It adds that this gives about 1.8 times more effective insulation and that thicker material gives more performance, but offers no test data. For context, the XLBK's 2.2 mm is within about 0.1 mm of the DMBK's 90 mil, so do not read one as clearly thicker. Our Recoil XLBK post covers that kit's aluminium layer, weight and peel strength, which the DMBK page does not give.
Is it constrained-layer damping?
Our listing calls the DMBK butyl-based constrained-layer damping. Wikipedia's article on constrained-layer damping describes a viscoelastic material between two stiff sheets, with the damping coming from shear in the viscoelastic layer. By our reading, that needs a stiff layer on the outside of the butyl, with the panel as the other stiff sheet, and Recoil's main-site page names no such layer: it does not mention aluminium at all, so we cannot confirm our listing's wording from Recoil. Recoil's own explanation, a promotional one without data, is simpler: added weight lowers a panel's resonant frequency, and the mat reduces rattles, road noise and vibration from music playback.
What is in the box
Recoil's main-site page says the kit includes an application roller, with a corrugated rotating wheel meant to stop slipping and an ergonomic handle, and a knife for trimming. It describes a peel-and-place application: trim, peel, place, then roll by hand. Recoil's US page also lists a roller and knife. Our listing mentions neither tool, so confirm with Recoil or the distributor.
What owners and reviewers say about the Recoil DMBK
When we checked in October 2026, Recoil's main-site DMBK page showed no reviews, its US page showed none, our listing has no reviews section, and we found no independent review or test of this mat. So there is no owner verdict to report, and we will not invent one.
Who should buy it, and who shouldn't
Buy the Recoil DMBK if you want a butyl kit that costs less per sheet than the XLBK at MRP, can confirm the sheet size before you plan the job, and will roll the mat on by hand.
Look elsewhere if you need an exact coverage figure before ordering, a published aluminium layer or temperature rating (the XLBK gives both), or a foam or absorber layer in the same product (see the Recoil DABK and Recoil SABK).
Installation notes for Indian cars
Our guide to applying sound damping in a car suggests removing the panels, cleaning the surfaces, and applying butyl first, starting with the doors, cut to size and rolled to remove air bubbles. As general practice, let the metal dry fully after any wash before you press the mat on, and roll it firmly.
Recoil's page gives no temperature range for the DMBK, so for hot areas such as the firewall, confirm with Recoil or the distributor. Our listing names doors, floor and boot. VA3 Car Studio in Ghaziabad offers professional installation, and builds custom boxes, pods and baffles if you are rebuilding speaker mounts as well.
Price and where to buy
The Recoil DMBK carries an MRP of ₹9,900 for the nine-sheet kit: see the DMBK listing. VA3 Car Studio often sells below MRP, so check the current price on the page. Warranty is per Recoil's published terms, which name no damping product and no region; confirm India terms with Recoil or the distributor. For other brands' sheets under ₹1,000 each, see our roundup of damping sheets under 1000 INR.
The bottom line
The Recoil DMBK costs less per sheet at MRP than the XLBK, ₹1,100 against about ₹2,222, but the sheet size depends on which source you believe, and the constrained-layer wording comes from our listing alone. Confirm both with Recoil or the distributor before you plan the job around a coverage total.
Recoil DMBK FAQ
What size are the Recoil DMBK sheets?
Our listing says nine sheets of 550 x 800 mm, while Recoil's main-site page says 18 x 32 in (457 x 812 mm) sheets and 36 sq ft in total. The two differ by about 18% in area, so confirm with Recoil or the distributor and measure on arrival.
How thick is the Recoil DMBK?
Recoil's page gives 90 mil, which is 2.29 mm, and our listing gives no thickness. The XLBK's 2.2 mm is within about 0.1 mm of that figure.
Does the Recoil DMBK come with a roller and knife?
Recoil's pages say a roller and knife are included. Our listing does not mention them, so confirm with Recoil or the distributor before you rely on that.
Is the Recoil DMBK constrained-layer damping?
Our listing says so, but Recoil's main-site page names no aluminium or other constraining layer, so we cannot confirm it. Recoil's own explanation is that added weight lowers a panel's resonant frequency.
