Where Can I Buy Acoustic Foam? Sellers Compared by Policy
If your room rings on every take and you’re asking where can I buy acoustic foam, the quick answer is a maker’s own store, a music retailer, a foam cutter or Amazon.
The trouble starts after you order, because foam cut to your size usually can’t go back, and one retailer’s Acoustic Foam category holds no foam wall tiles at all.
Pick the right seller and you’ll get the thickness you meant to buy, a fire test you can name and enough square feet for the walls and ceiling in one order.
You’ll see what each seller stocks, how it ships, what a return involves and how much foam a 10 by 12 foot room takes.
Start with the short list, because the right seller depends on whether you want a sized kit, a cut piece or a small test pack.
Where Can I Buy Acoustic Foam?
You can buy acoustic foam from four kinds of seller, and each suits a different order. Makers such as Auralex sell direct, foam cutters such as FoamOrder cut to your size, music retailers stock boxed brands, and Amazon lists makers’ packs beside many other brands.
| Seller | What it sells | How it ships | One fact to know |
|---|---|---|---|
| Auralex | Studiofoam wedges, pyramids and room kits | 3 to 5 or 7 to 9 business days, by product | Returns carry a minimum 20% restocking fee |
| FoamOrder | Dark gray open-cell foam cut to your size | Custom cuts usually ship in 3 to 14 days | Custom-cut foam isn’t returnable |
| SONEX | Melamine foam panels | Natural finishes: same day to 10 days | Online orders stop at 10 boxes |
| Markertek | Auralex, Sonex and Ultimate Acoustics foam | Drop shipments can take 4 to 6 weeks | Custom and special-order items can’t go back |
| zZounds | A page headed Acoustic Foam | Free ground shipping in the contiguous US | No foam wall tiles among its 13 products |
| Thomann | Auralex Studiofoam for UK and EU buyers | Mail order | 30-day money-back guarantee |
| Amazon | Auralex, Foam Factory, TroyStudio and many others | Marketplace | A title and a photo can disagree |
Foam Factory, Foam by Mail, SoundAssured, Soundproof Store and Arrowzoom also sell foam online, so read each one’s return page before you order.
The descriptions come from the sellers’ own pages and listings on 6 November 2026.
Once you know where, our list of the best acoustic foam panels for each room covers what to put in the cart.
Which Foam Makers Sell Direct?
Makers head that table because buying direct gets you their full range of sizes. Auralex, SONEX and Sonic Acoustics all sell from their own sites, while Foam Factory, JBER and TroyStudio sell under their own names on Amazon.
Auralex’s Studiofoam Wedges run from one bagged pair of 2 by 2 foot panels (8 square feet) to a box of 20 sheets at 1 by 24 by 48 inches (160 square feet). Its page says they ship in 7 to 9 business days, and some kits, such as the D24, in 3 to 5.
SONEX’s Classic panels are melamine foam rather than polyurethane, 24 by 48 by 2 inches with an NRC of 0.80 to 0.95. Its page limits an online order to 10 boxes and asks you to call for more.
Sonic Acoustics’ home page lists 12 by 12 by 2 inch tiles and free shipping on all US orders.
Foam Factory’s 24-pack listing on Amazon names its foam: open-cell polyurethane, an average NRC of 0.65 and a Class A rating under ASTM E84.
Can You Buy Acoustic Foam Cut to Size?
Those makers sell set sizes, so a sloped ceiling or a narrow alcove needs another route. Yes, you can buy foam cut to size, and FoamOrder’s acoustic page says every piece of its dark gray open-cell foam is cut to the size and thickness you order.
You pick a shape, enter the dimensions and get a quote, and custom cuts usually ship in 3 to 14 days. Some packing foams take the full 14.
The catch sits in FoamOrder’s return policy: custom-cut foam isn’t returnable, and an order can’t be canceled once it has started. Measure twice, because that piece is yours.
FoamOrder’s page also says soundproof foam can block noise, while Auralex says acoustical foam does little to stop sound leaking into or out of a room. Whatever the listing calls it, buy foam for echo inside the room, not for noise through walls or windows.
You can trim standard foam yourself instead. Auralex says a steady hand, a straightedge and an electric carving knife will do it, and our guide to cutting acoustic foam to size at home covers the details.
Which Music Retailers Stock Acoustic Foam?
Boxed foam from a retailer skips that cutting step, and Markertek, Thomann and Guitar Center are the names to try. Markertek’s Acoustic Foam category carries Auralex Studiofoam and Roominator kits, Sonex and an 18-pack from Ultimate Acoustics, beside items that aren’t foam, such as Green Glue.
zZounds shows why you should read past a category name. Its Acoustic Foam page held 13 products on 6 November 2026: 10 from Primacoustic, whose London and Broadway panels it calls fiberglass, plus three sets of speaker pads.
Thomann sells Auralex 2 inch Studiofoam Wedges and D36 Roominator kits to UK and European buyers.
Guitar Center listed Auralex and Primacoustic foam and panels on 3 October 2026, and Sweetwater, Musician’s Friend and B&H are other retailers to try.
Can You Buy Acoustic Foam Near You?
Those retailers mostly ship to your door, and walking out of a store with foam takes some checking. You can sometimes buy it locally, but confirm stock on your store’s own product page before you drive over.
Guitar Center’s category page had a Store Pickup filter on 3 October 2026, and its return policy then said an online order returned in a store avoids return shipping.
Home Depot and Lowe’s both sell foam panels on their sites, and Walmart, Target and Best Buy list them too.
Type acoustic foam near me into a search box and you’ll mostly get Yelp lists of soundproofing businesses, online shops and home-center categories.
Auralex’s own shortcut is its dealer locator, which covers dealers and distributors worldwide, or you can email or call and ask for a local dealer.
A local foam shop is worth a call, but ask for open-cell acoustic foam by name. Burton Acoustix’s normal foam comparison explains why ordinary foam won’t do the same job.
FoamOrder shows how thin local choice can get: The Foam Store of Marin has closed, and its page now sends buyers to the website.
What Are the Return Rules at Each Seller?
Local or shipped, the return rule is where foam sellers differ most. Boxed foam can usually go back within 30 to 45 days, often for a fee, while cut or custom foam usually can’t go back at all.
| Seller | Window | What can’t go back |
|---|---|---|
| Auralex | 30 days from receipt, minimum 20% restocking fee | Anything used, modified or damaged |
| FoamOrder | Many items aren’t returnable | Custom-cut foam |
| SONEX | Authorized returns only, with a restocking fee | Non-standard items |
| Markertek | 30 days, unopened, restocking charge up to 25% | Non-stock, special-order and custom items |
| zZounds | 45 days from delivery, no restocking fee when its steps are followed | Almost any product can go back with a return number |
| Thomann | 30 days | Items specially made or modified for you |
| Guitar Center | 45 days in original condition on 3 October 2026 | Clearance, discontinued and special-order items |
| Amazon | 30 days from delivery for many items on 3 October 2026 | Only many items qualify, so check the listing |
You pay return shipping at Auralex and Markertek, and SONEX wants returns sent freight prepaid. Thomann covers return delivery within the EU, Switzerland, the UK and Norway.
SONEX’s own pages disagree: Payment & Shipping says a 30% restocking fee and its Terms & Conditions say 50%. Get the figure in writing before a large order.
Auralex’s return policy asks for resalable foam, meaning unused, unmodified and undamaged, so glue or a knife ends that option.
What Should You Check Before You Buy Acoustic Foam?
Those rules mean a wrong box tends to stay yours, so check five things first. Thickness leads: Auralex gives its wedges an NRC of 0.50 at 1 inch, 0.75 at 2 inches, 0.90 at 3 inches and 1.10 at 4 inches, and it calls 2 inch your safest bet if you’re tuning a room yourself.
Read the listing’s dimensions as well as its title. One JBER six-pack’s title says 2 inches while the label on its main photo says 1 inch.
Density comes second, and many listings skip it. Auralex says look-alike foams are often much lower in density, which severely diminishes absorption, especially in mid and low frequencies.
Our guide on how to choose acoustic foam by thickness and density goes further.
The fire test comes third, because a word on a listing isn’t a test. Auralex’s pages list UL 94 HF-1, while the 2021 lab report it links says the material met UL 94 HBF in a burn test for plastics in devices and appliances.
SONEX says Class 1 and Foam Factory’s listing says Class A, both under ASTM E84, and Auralex’s E84 page puts Class A at a flame spread of 0 to 25.
One 2 by 4 foot pack’s fire-retardant photo shows a TB117 report, a smolder test for upholstered furniture. Auralex says to ask your local fire marshal or building inspector, and to use only products with a documented rating on a commercial job.
Coverage comes fourth, and it’s simple arithmetic. A 12 by 12 inch tile is 1 square foot, so a 12-pack covers 12 square feet, while a 2 by 4 foot sheet covers 8.
How it ships comes last, since some foam arrives squashed. TroyStudio’s listing says its foam comes compressed, SODOCT’s says to wait 24 to 48 hours for full shape, and Foam Factory’s says it ships uncompressed.
If yours arrives flat, this decompression walk-through covers the wait.
How Much Acoustic Foam Does a Room Take?
That square-foot math needs a target, and Auralex supplies one. Its coverage guidance puts most rooms at 25 to 75 percent of the walls and ceiling, and almost never 100 percent.
Control rooms for rock and hip-hop usually take 50 to 75 percent, jazz and classical control rooms 35 to 50, and most live rooms 25 to 50.
A 10 by 12 foot room with an 8 foot ceiling has 472 square feet of walls and ceiling. That makes 25 percent about 118 square feet and 75 percent about 354.
| Pack | Square feet | Packs for 25% | Packs for 75% |
|---|---|---|---|
| 12 tiles, 1 by 1 foot | 12 | 10 | 30 |
| 24 tiles, 1 by 1 foot | 24 | 5 | 15 |
| 40 tiles, 1 by 1 foot | 40 | 3 | 9 |
| 4 sheets, 2 by 4 feet | 32 | 4 | 12 |
| Auralex box of 12, 2 by 2 feet | 48 | 3 | 8 |
Those counts are arithmetic from Auralex’s percentages and each pack’s size. You don’t need them all on day one, since Auralex calls its 1 foot Wedgies a quick fix for spot treating.
Auralex’s Roominator chart offers a shortcut, but its Room Size column isn’t floor area. The sizes match walls plus ceiling at 8 feet high, so that 10 by 12 room sits on the 472 row, where the chart suggests one Deluxe Plus kit for a project studio.
Smaller kits come in plain numbers: the Streamer Starter covers 20 square feet and the D36-DST covers 36, for spaces of about 6 by 8 by 8 feet.
Which Seller Fits Your Room?
Those totals sort the sellers into jobs, and this table matches each need to a seller above.
| You want | Look at | Why |
|---|---|---|
| A kit sized to a room | Auralex or a dealer | Project Roominators bundle panels, bass traps and adhesive |
| An exact size | FoamOrder | Cut to your order, but not returnable |
| A small test | A 12-pack | 12 square feet to try on one spot |
| Bulk boxes | A 40-pack or Auralex boxes | Auralex boxes run up to 160 square feet |
| Big sheets | A 2 by 4 foot pack | Each sheet covers 8 square feet |
| A named fire class | SONEX or Foam Factory’s listing | Both cite ASTM E84 |
| Foam today | Your local store’s page | Confirm stock before you drive |

The Bottom Line
Buy from a maker or dealer when you want a sized kit and named fire data, and from a foam cutter only when you’re sure of the measurements, because cut foam usually can’t go back.
Start with a small pack if you’re unsure, check the listing’s thickness and fire test, and count square feet before you order.
Frequently Asked Questions
Where can I buy acoustic foam near me?
Start with your local music store and home center, and check stock on the store’s own product page. Guitar Center’s category page had a Store Pickup filter on 3 October 2026, and Auralex’s dealer locator lists its dealers and distributors.
Where is the cheapest place to buy acoustic foam?
There’s no fixed answer, because packs, sizes and sales keep changing, so this guide doesn’t rank sellers by price. Compare square feet at the same thickness, then add each seller’s stated terms: zZounds ships ground free within the contiguous US, and Auralex charges a minimum 20% restocking fee on non-defective returns.
Can you get acoustic foam cut to size?
Yes. FoamOrder cuts each piece to the size and thickness you order, though custom-cut foam isn’t returnable. You can also trim standard foam at home, and Auralex suggests an electric carving knife.
Can you buy acoustic foam at Home Depot or Lowe’s?
Both sell foam panels on their sites. Check your store’s product page for stock and return terms before you drive over.
Is soundproof foam the same as acoustic foam?
Sellers often use both names for the same absorbing foam. Auralex calls terms such as soundproof foam misleading, and it says wall-mounted foam treats the sound inside a room and doesn’t block it.
Can you return acoustic foam?
Boxed foam, usually, and cut foam, usually not. Auralex gives 30 days with a minimum 20% restocking fee on resalable foam, zZounds gives 45 days, and FoamOrder doesn’t take back custom-cut foam.
Can you get a sample of acoustic foam?
Yes, from some sellers. Auralex has a sample request form that covers Studiofoam colors, and FoamOrder lists foam samples, including fire retardant foam.
