Detail 01
Acoustical sealant, not standard caulk
Stays permanently flexible instead of curing hard, so it keeps sealing as framing moves and settles.

AuralexStopGap Acoustical Sealant
1/2
Independent shopping perspective
The Korena take
Acoustical sealant for filling gaps and seams in room treatment and studio construction. For anyone building or sealing a room, not treating one.
Strong match
Who this is for
- Sealing seams between drywall layers in a studio build
- Filling gaps around outlet boxes and penetrations in a wall
- Closing edge gaps where acoustic panels meet framing
Consider the trade-offs
When to look elsewhere
- Anyone wanting to absorb echo or flutter — this seals, it does not absorb
- Players looking for a quick room fix without construction work
- Anyone with no gaps to seal in existing walls
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Auralex brand
Made to pair with the same company's panel and treatment products, so it fits that workflow.
Detail 03
Under $25
Cheap relative to a room build, but you will need several tubes for a full room's seams.
Detail 04
Sealant, not a panel
Handles the air-leak side of isolation. Sound leaks through gaps, so sealing is separate work from absorption.
Final check
Know before you order
- 01Needs a standard caulking gun — not included
- 02Estimate your linear footage first; one tube covers a limited run
- 03Sealing gaps helps isolation, not room echo — buy panels for that
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this soundproof my room?
It closes air gaps, which is one part of isolation. Sound leaks through any opening. It does nothing for echo or reflections inside the room.
02Can I use regular caulk instead?
Standard caulk cures hard and can crack as framing moves. Acoustical sealant stays flexible so the seal holds long term.
03Do I need a caulking gun?
Yes. This is a tube product and no gun is included.
04How many tubes do I need?
Depends on your linear footage of seams. Measure the perimeter and joints you plan to seal, then buy accordingly rather than guessing.
