Recoil SABK Review: 25 Sheets of Black Absorbing Cotton and the Unexplained 400 g
The Recoil SABK is a box of 25 black sound-absorbing cotton sheets, each 500 x 700 mm, at ₹25,000 MRP, which is ₹1,000 a sheet. Our listing sells it as a second layer over a damping mat, but Recoil's own SABK page carries only a title and a SKU, so every specification here comes from our listing. It suits fitters who already have a damping layer down and will confirm what the listed 400 g density means before ordering. See the SABK listing.
Key takeaways
Our listing gives 25 sheets of 500 x 700 mm, which is 0.35 m² each and about 8.75 m² a box by our arithmetic.
The listed 400 g density has no stated basis; read per square metre, the box would weigh about 3.5 kg, and read per sheet, about 10 kg.
Our listing places the cotton over a damping mat in doors, roof and quarter panels; Recoil's page says nothing about use.
The ₹25,000 MRP is ₹1,000 per sheet, or about ₹2,857 per m².

Specifications follow our listing. Recoil's SABK page shows a title and SKU only, Recoil's damping category lists the SABK with no specifications, and we found no SABK page on Recoil's US site. Not listed means our listing does not say, not that the material lacks it.
What the listed 400 g density could mean
Density strictly means mass per unit volume, so a bare 400 g is not a density, and our listing gives no unit basis. As a general convention, fabrics and felts are often weighed in grams per square metre, but the listing does not say that, so treat it as a possibility only. For the arithmetic alone: read as 400 g per square metre, a sheet would weigh 140 g and the 8.75 m² box about 3.5 kg; read as 400 g per sheet, the 25 sheets would weigh 10 kg. The readings differ by nearly three times, which is why the basis matters. Confirm it and the sheet thickness with Recoil or the distributor before comparing the SABK with another absorber.
Absorbing noise is not the same as blocking it
Wikipedia's article on soundproofing says mass is what blocks sound, and that sound-absorbing material controls reverberant sound inside a cavity, enclosure or room. It adds that porous open-cell foams are highly effective across a broad range of medium to high frequencies and less impressive at lower ones, and that acoustic foam and other absorbent means are less effective against transmitted vibration. The article does not mention cotton, but it lists fibrous materials such as mineral wool and sheep's wool as deadening resonant frequencies within a cavity, and by our reading a cotton sheet belongs to that fibrous family.
Our listing says the SABK soaks up mid and high frequency noise, which fits what the article says of porous open-cell foams, though neither Recoil nor we have a measurement for it. By our reading, absorbent material is not a vibration fix, so it goes over a damping mat rather than instead of one, which is how our listing positions it. The listing makes no blocking claim, and nothing published suggests it adds the mass a barrier needs.
Sizing a job: area, sheets and waste
One sheet is 0.5 m by 0.7 m, or 0.35 m², so a box of 25 is 8.75 m². Neither our listing nor Recoil gives a coverage for any car. As general practice, measure the area you plan to cover, divide by 0.35 m² and round up, then allow for trimming waste around curves and clips.
At MRP the box works out to about ₹2,857 per m². That is in the range of the DMBK's roughly ₹2,500 to ₹2,960 per m², depending on which sheet size is right (our Recoil DMBK post sets out the mismatch), but the products do different jobs, and as listed the cotton goes over a mat, so the costs add rather than compete.
Specs to confirm before you buy
Our listing leaves these out and Recoil's page does not supply them, so confirm them with Recoil or the distributor.
The basis of the 400 g density: per square metre, per sheet or something else.
The thickness of a sheet.
The backing: whether it is self-adhesive or needs a spray adhesive.
Any moisture, mould or flame treatment, since doors and the roof lining can see damp.
The temperature range, if you plan to fit it under the roof lining.
Warranty terms in India.
What owners and reviewers say about the Recoil SABK
When we checked in October 2026, Recoil's SABK page showed no reviews, we found no SABK page on Recoil's US site, our listing has no reviews section, and we found no independent review or test of this cotton. There are no owner reports to relay, and we will not make any up.
Recoil SABK against the other Recoil damping kits
The Recoil XLBK and DMBK are butyl mats, and the Recoil DABK is listed with foam built into the mat. The SABK is the only one of the four that is cotton, and the only one sold by the box of 25. It is the lowest per sheet at MRP, ₹1,000 against ₹1,100 for the DMBK, ₹2,000 for the DABK and about ₹2,222 for the XLBK, but the sheet sizes differ or are unlisted, so that gap says little.
Who should buy it, and who shouldn't
Buy the Recoil SABK if you already have a damping mat in doors, roof or quarter panels, or are fitting one, and want a separate absorber layer on top, and you will confirm the density basis, thickness and backing before you order.
Look elsewhere if you want one product that also damps panel vibration, published weight and thickness figures, or a stated adhesive. The SABK listing gives none of those, and as listed the damping is left to the mat underneath.
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, with other layers after and the trim refitted so nothing rattles. It does not mention cotton, so the only placement guidance is our listing's: over a damping mat, in doors, roof and quarter panels. With no backing listed, confirm how the sheets are meant to be held in place.
No moisture, flame or temperature rating is listed, so confirm those with the maker before covering a door cavity or roof area. VA3 Car Studio in Ghaziabad offers professional installation if you would rather have the layers fitted together.
Price and where to buy
The Recoil SABK carries an MRP of ₹25,000 for the 25-sheet box, which works out to ₹1,000 a sheet: see the SABK 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.
The bottom line
The Recoil SABK is a 25-sheet box of black cotton, about 8.75 m², whose only published specifications are on our listing, and its 400 g density has no stated basis. Confirm the basis, thickness and backing before you pay the ₹25,000 MRP.
Recoil SABK FAQ
What size are the Recoil SABK sheets?
Our listing gives 500 x 700 mm, which is 0.35 m² a sheet, so a box of 25 is about 8.75 m² by our arithmetic. Recoil's own SABK page gives no size, so confirm with Recoil or the distributor.
What does 400 g density mean for the Recoil SABK?
Our listing does not say. A bare 400 g has no area or volume basis, so it could be per square metre or per sheet, and the box would weigh about 3.5 kg or 10 kg respectively. Confirm the basis with Recoil or the distributor.
Does the Recoil SABK replace a damping mat?
Not according to our listing, which places it as a second layer over a damping mat for doors, roof and quarter panels. Wikipedia's soundproofing article also says absorbent material is less effective against transmitted vibration.
Does Recoil publish specifications for the SABK?
When we checked in October 2026, Recoil's SABK page showed a title and SKU only, with no description, specifications or reviews, and we found no SABK page on Recoil's US site.
