The Best Materials for Soundproofing Barn Doors

Mass Loaded Vinyl (MLV)A heavy, sound-absorbing material made of vinyl and asphalt.Can be used to reduce noise transmission through walls, ceilings, and floors.
Acoustic CaulkA flexible, sound-deadening material that is used to seal gaps and cracks.Can be used to prevent noise from traveling through gaps in walls, doors, and windows.
Soundproof InsulationA material that is designed to absorb sound waves.Can be used to reduce noise transmission through walls, ceilings, and floors.
Acoustic BarriersA physical barrier that is designed to block sound waves.Can be used to reduce noise transmission between rooms or between a building and the outside environment.

Installing barn doors in your home can add a stylish, modern touch. However, these large sliding doors often have gaps that allow sound to travel between rooms. If you want to reduce noise coming through the door, there are several effective soundproofing materials to use.

The key is finding products that block, absorb, and seal sound. Used together, these materials can greatly reduce noise transfer through a barn door. Here are the best options:

Mass Loaded Vinyl

Mass-loaded vinyl (MLV) is a heavy, flexible vinyl material designed to block sound. MLV works by adding mass to the door, which reduces sound vibration and transmission.

MLV sheets can be cut to size and applied to the door itself. For even better performance, adding MLV to both sides of a hollow core door creates a soundproof sandwich. The weight and density of MLV make it one of the most effective soundproofing materials.

Acoustic Caulk

Gaps around and under the door are common pathways for sound to travel. Acoustic caulk is formulated to seal these cracks and openings.

Apply caulk around the edges of the door, as well as above and below it. Look for caulk labelled “acoustic” or “soundproofing” to ensure maximum noise blocking. Properly sealing gaps with caulk prevents sound leaks.

Soundproof Insulation

Insulation designed for sound dampening can be used inside a hollow core barn door to absorb noise. Roll or rigid fibreglass insulation works well.

Cut pieces to fit tightly inside the door cavity. The fibres in the insulation soak up sound vibrations rather than transmitting them through the door. This reduces the level of noise able to pass through.

Acoustic Barriers

For even more sound blocking, install acoustic barriers on the walls around the door. Acoustic drywall, mass-loaded vinyl sheets, noise-damping tiles, and other barriers absorb sound and reduce transmission to adjacent rooms.

Layering multiple soundproofing materials provides the highest level of noise reduction. MLV, caulk, insulation, and acoustic wall treatments work together to close the gaps and prevent barn door sound transfer. Properly installed, your stylish sliding barn door can also be very quiet.

How to Effectively Soundproof Barn Doors

Barn doors are a popular design choice for both home interiors and commercial spaces. However, the large gaps and hollow construction of many barn doors allow sound to travel freely between rooms.

Fortunately, there are ways to modify and treat a barn door to significantly reduce noise transmission. With some simple upgrades and soundproofing techniques, you can have both the style of a barn door and the acoustic privacy you need.

Choose High-Quality Soundproofing Materials

When soundproofing a barn door, it’s important to use high-quality materials that are designed for acoustic isolation. Cheap, low-density products may not block sound effectively and will need to be replaced sooner. Investing in top-tier soundproofing materials makes a difference in noise reduction.

Look for materials like:

  • Dense rubber or vinyl for door seals and sweeps
  • Mass-loaded vinyl (MLV) sheets for adding door mass
  • Acoustic caulk for permanent seals
  • Soundproof insulation with high noise reduction ratings

Quality soundproofing materials are readily available from top manufacturers. While more expensive initially, the improved noise blocking and durability provide better long-term value.

Understand How Barn Doors Leak Noise

To soundproof a barn door, you first need to understand where it is lacking acoustically. Noise leaks can occur:

  • Around the edges between the door and the frame
  • Underneath at the floor gap
  • Through the thin, hollow door construction

Even when closed, gaps around a standard barn door typically measure a quarter inch or more. These openings allow sound waves to pass directly through. Sound also travels easily through the lightweight plywood or particleboard used in hollow core doors.

Addressing these weak points is key to stopping sound transmission.

Seal Perimeter Gaps Around the Door

The person should be using a caulk gun and should be wearing safety goggles and gloves. The door should be

The first priority is sealing the gap between the sliding door and the frame. Weatherstripping or door sweeps can be installed around the perimeter to close these openings. Carefully measure each side of the frame to cut pieces to an exact fit.

Apply adhesive acoustic sealant in any uneven spots and firmly press weatherstripping into place, forming an airtight seal around the entire perimeter. Leave no gaps where air and sound can leak through.

For the best noise isolation, use products rated for acoustical sealing rather than standard weatherstripping. Look for materials heavy enough to completely fill the gaps. A tight seal is essential.

Add Bottom Door Seals

Prevent sound from travelling under the door by installing proper seals along the bottom. Measure the width of the door for the appropriate length. Position seal strips to evenly contact the floor, using adhesive if needed to attach.

For barn doors, choose a product with a maximum sweep length to accommodate an uneven floor. Sufficiently thick material will conform to the floor and block noise even if the gap varies. A door bottom seal is a quick and effective way to greatly reduce sound leakage.

Increase Door Mass and Density

The most substantial soundproofing upgrade is adding mass to make the door itself less acoustically permeable.

One option is replacing the existing door. A solid wood or solid core door has much greater mass than a lightweight hollow core version. The dense construction better contains noise.

For existing doors, significantly improving the sound blocking requires adding layers to the door surface. Materials like mass-loaded vinyl (MLV) provide excellent mass and density. Cut pieces to size and use spray adhesive to layer MLV sheets on both sides of a hollow door.

Install Interior Acoustic Insulation

Filling the interior of a hollow door with insulation absorbs sound passing through. Use acoustic insulation designed for blocking noise, such as mass-loaded vinyl composite. Precisely measure and cut pieces to fit tightly inside the door cavity for maximum coverage and effectiveness.

Installing insulation along with MLV sheets, acoustic seals, and bottom door seals results in comprehensive soundproofing on a budget. The combination addresses the weak points of an existing hollow barn door.

Soundproofing Costs

The cost to soundproof a barn door can range from $50 to $600, depending on the methods used:

  • Door seals – $50 to $150
  • MLV sheets – $100 to $200
  • Acoustic insulation – $75 to $150
  • New solid core door – $200 to $600

Simple DIY upgrades like weatherstripping and door bottom seals provide noticeable improvements at a low cost. Replacing the door or adding multilayered MLV and insulation offers superior soundproofing for a higher budget.

Best Practices for DIY Soundproofing

With the right materials and techniques, it is possible to effectively soundproof a barn door yourself:

  • Carefully measure and seal all gaps with quality products designed for acoustical isolation. This is the top priority.
  • Increase door mass and density as much as is practical with MLV, wood veneers, or composite boards.
  • Make sure insulation completely fills voids and use appropriate acoustic products.
  • Layer noise-blocking curtains over doors and consider wall panels.
  • Combine methods like seals, add mass, curtains, and foam wall treatments for best results.

A bit of effort can transform an acoustic problem into a stylish yet peacefully quiet barn door. Use this comprehensive soundproofing guide to reduce noise issues and enjoy your beautiful new sliding door. With the right upgrades, you can have both design and quiet.
