Is Mdf Good For Soundproofing?

Is Mdf Good For Soundproofing?

MDF is a good material for soundproofing because it’s thick and dense, which helps it absorb sound and lower noise levels. Its excellent soundproofing abilities come from its thickness, density, and STC rating. MDF is also quite sturdy, which makes it ideal for soundproofing projects that need structural stability.

MDF is not the best material for soundproofing, and it’s only a little better than solid wood. If you’re looking for an affordable soundproofing material, covering walls with thick cushions and carpets may be a more suitable option.

Soundproofing Basics

How sound travels

Have you been in a room and heard people talking through walls? Sound moves in waves that travel through the air, bouncing off surfaces to pass through. That’s why sound can get through walls and ceilings. Soundproofing is needed to stop or lessen it.

Sound transmission classes

Sound transmission classes (STC) determine how effectively a material can stop the spread of sound. The higher the STC rating, the better the material works for soundproofing.

a regular wall constructed with drywall and wood framing has a sound transmission class (STC) rating of around 30.

Meanwhile, a solid concrete wall can have an STC rating of 60 or higher. This means that the concrete wall is much better at blocking sound than the drywall and wood wall.

Soundproofing materials

To reduce noise levels, different materials are used for soundproofing. The most common ones include:

MDF Characteristics

What is MDF

MDF stands for Medium-Density Fiberboard. It is an engineered wood product made up of wood fibres, resins, and wax that are pressed together under high temperatures and pressure to create flat, hard boards.

MDF is a versatile and affordable alternative to plywood and other engineered wood products. It comes in various thicknesses and sizes, with full sheets typically measuring 4 x 8 feet.

MDF is often used in construction, furniture-making, and cabinetry due to its smooth finish and easy machinability. MDF is a material that’s created by recycling wood products.

These VOCs can be damaging to the environment. However, most types of MDF are still considered sustainable products.

How MDF is made

MDF is made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrillator. The wood fibres are then mixed with a resin binder and wax, and the mixture is formed into panels by applying high temperature and pressure.

The general steps used to produce MDF include mechanical pulping of wood chips to fibres, drying, blending fibres with resin and sometimes wax, forming the resinated material into a mat, and hot pressing.

The furnishing for MDF normally consists of wood chips. The resin and wood fibre mix is evenly distributed into a thick layer and then pressed to form the dense MDF board.

The boards are sanded, trimmed, and sawn into appropriate sizes. MDF can be directly coated in a wide variety of colours or patterns.

Strengths and weaknesses of MDF

Before using MDF in a project, it’s important to think about its pros and cons. Some of the strengths of MDF include:

  • Machinability: MDF is easy to cut, drill, and shape, making it a popular choice for furniture-making and cabinetry.
  • Smooth surface: MDF has a uniform, smooth surface that is free of knots and other imperfections, making it ideal for painting or laminating.
  • Cost-effective: MDF is generally less expensive than solid wood or plywood, making it a popular choice for budget-conscious projects.
  • Consistent quality: MDF is manufactured to be consistent in size and density, which can make it easier to work with.

However, MDF also has some weaknesses that should be considered:

  • Not as strong as solid wood: MDF is not as strong as solid wood and can be prone to breaking or sagging under heavy loads.
  • Water damage: MDF can absorb water and swell or warp if it is not properly sealed or protected.
  • VOC emissions: The resins used to bind MDF can emit volatile organic compounds (VOCs), which can be harmful to the environment.
  • Not suitable for outdoor use: MDF is not recommended for outdoor applications because it can rapidly deteriorate when it comes into contact with moisture.

MDF for Soundproofing

When my roommate began playing the drums, I understood the significance of soundproofing immediately. We needed to lessen the noise and preserve our mental health.

We researched several alternatives and found out that MDF (medium-density fiberboard) could be used as a soundproofing material.

MDF’s acoustic properties

MDF, or medium-density fiberboard, is a type of wood material created by pressing wood fibres and resin together. The resulting material is uniform and compact, with acoustic properties that can absorb sound waves and prevent them from passing through.

Thanks to its smooth surface, MDF also reflects sound waves, which makes it ideal for enhancing sound quality in a room.

MDF’s effectiveness in reducing noise

We had a good experience using MDF as a soundproofing material. We installed MDF panels on our practice room walls and noticed a big drop in noise that spread to other rooms. MDF has a high density and thickness that can block sound waves, making it an excellent material for reducing unwanted noise.

Comparison with other soundproofing materials

After comparing MDF with other soundproofing materials, we discovered that it is an affordable choice. While materials like mass-loaded vinyl or soundproof drywall offer better soundproofing, they are more expensive. MDF is a practical option for people on a budget as it can be easily found and installed.

How to Use MDF for Soundproofing

As we were remodelling our home office, we aimed to make a calm and quiet work environment. We picked MDF for soundproofing due to its flexibility and affordability.

Here are some useful suggestions, top practices, and cost considerations to remember when using MDF for soundproofing.

Installation Tips

We found that MDF worked well to soundproof our home studio. Here’s how we did it:

  • Measure the area: measure the area that needs soundproofing and calculate how much MDF you’ll need.
  • Cut the MDF: Cut the MDF sheets to the right size with a saw, wearing goggles and a mask to protect yourself from sawdust.
  • Apply adhesive: Use a trowel or caulking gun to spread construction adhesive in a zigzag pattern on the back of the MDF sheets.
  • Place the MDF sheets: Put the MDF sheets on the surface to be soundproofed and press them firmly, making sure they’re level.
  • Seal the edges: Use an acoustical sealant to seal the edges of the MDF sheets to prevent sound from leaking out.

Best Practices

If you want to soundproof using MDF, here are some tips:

  • Use more than one layer: It’s best to use multiple layers of MDF to improve soundproofing. We suggest using two ¾-inch MDF layers with the green glue-damping compound in between.
  • Use thick MDF: Thicker MDF sheets work better for soundproofing. We used ¾-inch thick MDF sheets.
  • Cover everything: For the best soundproofing results, cover all the walls, ceiling, and floor of your room or studio with MDF.

Cost Considerations

MDF can be a good choice for soundproofing your space without spending too much. It’s cheaper than other materials like soundproof drywall or mass-loaded vinyl, although the cost will depend on how much you need and the size you’re looking for.

You can usually find MDF at hardware stores without any trouble.

FAQs for MDF For soundproofing

is mdf wood waterproof?

MDF is not resistant to water. It’s composed of wood fibres, resins, and wax that can absorb water, leading to swelling and deformation when exposed to moisture. some MDF products can withstand moisture to a certain extent, known as moisture-resistant or waterproof MDF.

does mdf get termites?

Yes, MDF can be susceptible to termite infestation. Termites are known to consume MDF, which is made from wood fibers, resins, and wax. While MDF has a higher density of glue than natural wood, termites can still nibble on it.

is MDF plywood or hardwood?

MDF is not the same as plywood or hardwood. It’s a kind of manufactured wood that’s created by pressing and bonding together wood fibres, resins, and wax at high temperatures and pressure. This process results in a composite wood with uniform strength and density across the board.

does mdf wood break easily?

MDF or Medium Density Fiberboard is a sturdy and compact material that’s commonly used in furniture and construction. However, it’s more prone to breaking or cracking when exposed to excessive pressure compared to solid wood or plywood. MDF is created by joining wood fibres with resins and heat to produce a strong and even board.


We studied MDF’s qualities for soundproofing and found it to be a good option. MDF is a dense material that absorbs sound well, making it effective at reducing noise levels. It’s affordable, easy to get, and simple to install with the right techniques.

Our experience with MDF for soundproofing has been positive. Our home studio became a more comfortable place to work and relax after we used it to reduce the noise levels.

Keep in mind that MDF alone may not fully soundproof a space, so you might need additional materials for better results.

Consider using MDF for your next soundproofing project to create a quieter and more peaceful environment.
