There are many reasons for appearing gaps and cracks and the main reason is if you have constructed your house years ago. But this is not the only exception it might be due to many other reasons.

You need to find out the spots and fill those gaps and cracks for a soundproof sliding glass door. Therefore you can find those spots by getting up at night closing your light and making sure your neighbor’s light is on then you will spot the cracks and gaps by the light coming from another side.

Those are the spots you need to fix first you can use acoustic sealant or caulk to fill up the cracks and gaps. Sound travels through air therefore sealing all the cracks and gaps is necessary for a soundproof sliding glass door.

Most people don’t pay much attention to gaps and cracks thinking they are tiny and unbothered with the noise they transmit believe it or not they are real culprits in passing the noise in the room through the door.

2. Soundproof Curtains

Soundproof curtains are one of the best solutions for different types of sound. Whether you’re facing the issue of noise or need to block noise in the apartment then soundproof curtains will do the job for you.

Soundproof curtains have a layer of insulation that will protect them from harmful UV rays and direct sunlight also it is one of the cheapest and best solutions for soundproof windows and curtains.

Therefore they will be maintained in a room and protected from direct sunlight which is thermal insulation. Ensure to get a thicker layer of soundproof curtains the thicker the layer is the denser it will block out the noise.

Then insulate the soundproof curtains on the windows completely. Make sure to get a little longer curtain from the doors because the curtains which lay on the floor will absorb the noise more effectively.

  • Noise blocking thermal insulation

  • Maintains room temperature 

  • 3 layer material fabric

  • Perfect for reducing noise and light

3. Soundproof Blanket

A soundproof blanket is one of the best ways to soundproof sliding glass door. This might sound funny but doors can have a blanket that’s not like a usual blanket but the soundproof one.

The soundproof blanket should be attached to your door. This is one of the cheapest ways to soundproof sliding glass doors and reduce the outside noise. but you need to keep in mind that this blanket will cover the door’s appearance.

Therefore if you want the job to be done without investing much and you don’t really care about the appearance of your door then this is one of the best ways to soundproof sliding glass door.

  • Wooven cotton, polyester

  • Great large acoustic blanket to absorb sound...

  • 100% recycled cotton filler. 

  • Grommets for easy hanging...

4. Install Weatherstripping

Weatherstripping is one of the cheap and handy solutions you can try as it offers several layers of protection. Weatherstripping is a type of insulation that will help you seal all the gaps around the doors.

It’s commonly made as rubber tape and plastic lath which you can easily attach to your door with the adhesive. It will help in providing protection against thermal leaks protection, and soundproof protection which along with several other protections will also help to reduce outside noise.

Weatherstripping is easy to install you don’t face any difficulty in installing it on doors.

  • The foam tape is made from environmental protection material, CR foam, Neoprene, which has excellent sealing and resistance to deformation feature, toxic free, can be used from -50℃ to 150℃.

  • Provides a perfect air-tight seal, sound proof, heat insulation, weather proof, oil resistance, resistant to corrosion, dust proof, shock-absorbing, buffering, sealing, flame retardant, anti-skidding and insulating.

  • Adjustable and Flexible. The Neoprene sponge foam tape is easy enough to customize and cut to size with scissors or blade, and bend easily and conform to any shape.

5. Use Mass Loaded Vinyl

The primary thing to create a strong barrier to noise is to increase the mass and density of the wall by adding an extra layer of mass-loaded vinyl to the soundproof sliding glass door.

Mass-loaded vinyl is a thin flexible and high STC especially used for blocking out sound waves and noise transmission. It is made up of synthetic plastic material.

MLV doesn’t absorb the sound waves as it has a reflective surface but it will effectively block out the sound waves passing through the wall. It will add an additional layer to the sliding glass door which makes a strong barrier against the sound.

Moreover one of the best things about mass-loaded vinyl is its thickness and mass ratio. Everything that is thicker has mass but this is not with vinyl it has the best thickness-to-mass ratio.

Because of its best thickness, it is recommended for soundproofing sliding glass door and the ability to cover the entire sliding glass door.

Here are some of the steps to install MLV

  • Cut the MLV sheet with the proper size of the door and make sure to pay close while marking the size on the sheet if it goes wrong then the material will be wasted.
  • Start from the top of the door to get a better idea of which side is fitting well and to get a good finish.
  • Apply the MLV on the top corner and from there roll down the sheet to the bottom for complete insulation.
  • If you want to add the additional layer of MLV you can do that for effective results.

Here is my recommendation for mass-loaded vinyl it is a bit more expensive than the other sheets of MLV but it’s worth spending for a soundproof sliding glass door.

  • Use for soundproofing basement, conference room.....

  • Durable and flexible

  • STC rating thick and odorless...

6. Rearrange Furniture

Now, this is one of the ways that doesn’t require any investment and you would be thinking will this method work then let me tell you this method works pretty well.

Rearranging furniture will help in providing mass to the walls and floor which block out noise and completely reduces echoes in a room. And if you don’t want to do this then as mentioned earlier use softer material.

However, you can load your wardrobes and bookshelves because it provides more mass to the walls which makes it denser and reduces all the echoes that are passing through the walls.

So, rearrange furniture and you will feel the difference when you implement this way as there will be more space created in your house or room.
