Did you know that glass doors are one of the most common sources of sound transmission in a house?

Well, doors are essential in any home, whether they are sliding or swinging. Sliding doors provide a nice alternative to traditional doors and can open up your space for natural light. They also offer more flexibility when it comes to decorating your home because they do not take up floor space like swing doors would.

Sliding glass door s are also not very well insulated and therefore they are among the main objects in the house that create polluting sound noise.

A lot of people don’t know soundproofingof sliding glass door is possible, but with the right materials and some time, this is an easy project for anyone to tackle at home on their own.

What factors made sliding glass door so noisy?

The primary source of noise can be attributed to the actual movement of your sliding glass doors. The kinetic energy produced by this motion is transferred into vibrations which are transmitted through the opening and closing of your door, causing excess noise in its wake.

Other factors include interior/exterior weather conditions (rain, sun exposure etc.) as well as exterior yard activities such as lawn mowing or children playing on play sets resulting in vibration noises that travel via windows and walls.

What is a Sound Transmission Class?

A Sound Transmission Class (STC) is a standard measure for how well an object or material resists sound transmission, and it’s used to rate how effective your glass door insulation will be.

The higher the STC rating, the better insulator you have against noise pollution. For example: if outdoors has loud music playing with doors closed and windows shut in adjacent rooms of house A vs House B; just by comparing their respective STCs we can see that House B would suffer less from exterior noises than its neighbor across street with weaker walls, windows and doors.

For most common residential applications, a double glazed unit has about 28-30 dB reduction capability at frequencies above 500 Hz . Please note that this does not mean only sliding glass doors

STC of a sliding glass door

A standard sliding glass door has an STC of 20, which is how it will be rated for soundproofing.

For effective noise reduction on a sliding door, you need to use materials with at least as good (or better) STC rating than the one your windows came with – this would mean upgrading from glazing that has an STC of 20 to one with a rating above 27.

This level of insulation will reduce up to 90% noise pollution from exterior noises, for example traffic or lawn mower vibrations.

Other glass door soundproofing methods

You can use double glazing for the best soundproofing results, but it would be wise not to rely on this option if possible, as what is ideal may not always fit your budget or living conditions. Different panel layouts affect how well a device performs with the specific sounds mentioned earlier. That’s why you should consider how much space you have before deciding how many panels are required. Professionals use a variety of techniques when adding multiple layers of glass inside window frames.

However, other options to soundproof your sliding door might be used.

  • Use foam insulation or additional lining around the edges of your sliding glass door for more soundproofing options. You may also apply 2-inch acoustic foam around the perimeter of where the door meets with wall or floor
  • Buy weather stripping for the bottom of the door.
  • Purchase an acoustic door kit, which will cover the door and act as insulation between it and the hallway or room next to it. This type of kit may require professional installation by a contractor.
  • There are also other options like soundproof curtains that attach over the opening of your sliding glass doors with magnetic strips. These types of curtains work by blocking outside noise while still allowing light in, making them perfect for any home or office space!

  • Put up a layer of drywall over where the foam has been applied before painting.
