Comprehensive Soundproofing for Existing Doors for Maximum Effectiveness
Our Acoustic Door Treatment Kits provide an easy and effective solution for upgrading nearly any door to achieve superior sound control. Designed for versatility and high performance, these kits include high-quality perimeter seals and an automatic door bottom, engineered to minimize sound transmission and create a better acoustic barrier. Whether you're addressing noise concerns in a professional or residential setting, our kits offer an easy-to-install solution without the need for full door replacements.
Installing an Acoustic Door Treatment Kit is a straightforward process that requires minimal tools. Our kits come with all necessary mounting hardware and instructions, allowing for quick and efficient application without professional expertise. The result is an enhanced acoustic environment with minimal effort and expense.
Our Acoustic Door Treatment Kits are available for nearly all standard door types, making them an excellent choice for a wide range of applications. Whether you're upgrading an existing wooden, metal, or composite door, our kits ensure a hassle-free installation process. While they are not compatible with full glass doors, we do offer custom glass door gasketing solutions to provide a similar level of noise reduction for specialty applications.

Frequently Asked Questions
A: Gaps are the number-one reason doors underperform acoustically. A 1/8″ continuous gap around a door can leak as much sound as a several-square-inch hole in the wall, so adding perimeter seals and an automatic door bottom can yield big gains. In typical field conditions, well-fitted gasketing and a drop seal can add approximately 3–10 STC points to a standard solid-core door system, depending on the slab construction, frame rigidity, and threshold treatment. You’ll hear the biggest improvements when the undercut is controlled, and latch-side compression is set correctly. Expect especially noticeable reduction in speech frequencies (500–2,000 Hz), with additional benefit at higher frequencies like clatter and hallway noise. Low-frequency sound (mechanical rumble, bass) still benefits, but results depend more on door mass and wall design. Remember: lab STC values are measured under ideal conditions; your field NIC will reflect real-world gaps, adjacent walls, glazing, and HVAC paths.
A: Most kits include perimeter jamb/head seals (magnetic or silicone bulb), an automatic door bottom (ADB) or high-performance sweep, and a threshold. For pairs, a meeting-stile astragal is added to seal between leaves. Carriers are typically anodized or powder-coated aluminum with field-trimmable lengths; seals are silicone, neoprene, or magnetic vinyl selected for durability and compression recovery. Kits are designed to fit common 1-3/4″ solid-core wood or hollow-metal doors in standard frames; options exist for 1-3/8″ slabs, oversized doors, and uneven floors. We match finishes (clear, bronze, black, white) to hardware and provide profiles that minimize sightline impact. If you have fire-rated assemblies, we supply listings that maintain the label when installed per instructions. For ADA transitions, we specify low-profile, beveled thresholds or surface-mounted ramps paired with drop seals. Send door and frame dimensions (including reveal and undercut), and we’ll configure a kit that fits precisely.
A: Installation is straightforward for those comfortable with precise measuring and drilling. Typical tools include a tape measure, square, miter saw or hacksaw, drill/driver.
A: Properly adjusted seals should not make doors unreasonably hard to operate. We select low-friction bulb or magnetic gasketing and tune the closer and latch so opening forces stay within applicable accessibility guidelines. Automatic door bottoms only engage at the last fraction of travel—when the latch seats—so they don’t drag while swinging. For accessibility, we specify beveled, low-profile thresholds and ensure clear floor transitions. Fire-rated doors can use listed seals that preserve the label; in smoke-control corridors, certain gaskets also provide smoke and draft resistance. Good acoustics also improve life safety by enhancing speech intelligibility for announcements.
A: After installation, start with simple checks: stand on the latch side in a dark room and perform a flashlight test—no light should show at the perimeter. Close the door on a strip of paper in several spots; gentle resistance confirms compression. Next, listen for changes in speech audibility from the corridor; you should hear a clear reduction.
