How To Soundproof Sliding Glass Doors In 4+1 Steps{💯Working}

The sliding glass door is one of the aesthetic decors of the room. They increase the look of the room 2 to 3 times. But the sliding glass doors come with a problem which is the passing of sound thru it.

There are many ways to soundproof the sliding glass doors but some of them are costlier and damages the look of the door(for which we install the glass doors).

Here I will try my best to teach you how to soundproof sliding glass doors in the cheapest ways possible and will not harm the look of the door.

How To Soundproof Sliding Glass Doors

The 5 steps I have picked up are the simplest ways to reduce the entering and exiting of the noise thru the sliding glass doors.

  • Door sealing strips
  • Soundproof curtains
  • Moving blankets
  • Thick blinds
  • Triple Pane Glass(optional)

1. Door sealing strips

The biggest drawback of installing the sliding doors is the gaps between the adjoining areas. When we shut the door, in the majority of cases, the doors have a gap between the frames and glasses.

You can use Adhesive Foam Tape or soundproofing strips in those gaps. They are available in multiple lengths and thicknesses.

Usually, they are weatherproof, oil-resistant, resistant to corrosion, dustproof, shock-absorbing, sound and heat insulation, anti-skidding, and insulating.

Adhesive foam tape will help to seal the gaps between doors and frames and will not let the sound enter or exit thru the door.

2. Soundproof Curtains

Using the sound deadening curtains is the most aesthetic way to soundproof sliding glass doors. The soundproof curtains are very effective to an extent but yeah can’t block 100% of sound.

If there are gaps thru which the sound is entering, hang the acoustic curtain before those gaps. It will absorb the sound and will prevent bouncing back of sound.

Soundproof curtains are thicker than ordinary curtains. They absorb the sound vibrations and don’t let them bounce back so that the echo effect gets decreased.

Usually, the sound deadening curtains have three layers, the middle one is the thicker one. Almost all acoustic drapes are blackout so if you use them on the glass doors, they will block the natural light. You may take it as a drawback of using the sound-deadening curtain.

When it comes to soundproof curtains, NICETOWN’s name will be taken obviously. They produce acoustic curtains in multiple dimensions and have a great quality with reviews. I will suggest you go with NICETOWN Blackout Curtain for the best result.

3. Moving Blankets

soundproof blankets or moving blankets

The use of moving blankets or soundproof blankets is good for soundproofing the windows or sliding doors. If we compare the soundproof curtain and soundproof blankets, the soundproof blankets are better at sound-absorbing because they are thicker and denser than them.

But the drawback of using the blankets is they destroy the look of the sliding glass door for which we install. We can’t look thru the door and as they are heavier than the curtains, it will not be comfortable to move them anytime unlike curtains.

There are two ways to install the moving blankets, one is to stick them on the wall with nail or glue, another is installing the grommets on the top of the blankets and hang them on the curtain rods just like curtains.

Never go with the sticking on the wall. I always prefer installing the grommets and hang them like the curtains. It will make them easy to slide and let natural light come in.

4. Thick blinds

thick blinds

Many people suggest using thick blinds also to soundproof the sliding doors but it is not the best way to do so.

The blinds are designed especially for the windows and almost all blinds come in window size only. But yeah they work well in soundproofing.

If we compare the curtains and blinds, the curtains work better than the blinds because the blinds usually bounce back the sounds but curtains absorb them(and this decreases echo).

It is true that you can easily move the blind to see thru the glass door. Aesthetically it is good but not better than the curtains.

5. Triple Pane Glass(optional)

Triple Pane Glass

Installing the triple-pane glass is not a cheap way so I have put this way is optional. Although it is the most effective way to soundproof the sliding glass door.

If the frequency of the sound entering your room is high then you can go with installing the triple-pane glass or else it is better to choose other options mentioned above.

Low frequency sounds like four-wheeler engine noises and high-frequency noises are like trains passing by.

Benefits Of Sliding Glass Doors

There are a lot of benefits of installing the sliding glass doors. Let’s discuss the main advantages here:

  • Adds an aesthetic look to the room(for which most of the people install sliding glass doors)
  • Prevents dust particles from entering the room hence keeps the room clean
  • Keeps the temperature of the room constant, good for cold days
  • Good at preventing the noise from entering or exiting the room
  • If the glass is laminated tempered glass, then it is very difficult to break also, hence increases security
