How to Choose a Soundproof Interior Door
When shopping for a soundproof interior door, choose one of solid construction with good sound-deadening properties.
For an even greater level of soundproofing, consider a core foam-filled door — this will add further insulation and dampen more sound.
Various door seals are available that can help provide additional protection from outside noise.
Which Types of interior doors are more Soundproofed?
When choosing a soundproof interior door, it’s important to consider the type of door you’re looking for.
- Hinged doors are the most common and can be made from solid wood, aluminum, or steel. Solid wood doors are usually the most effective at blocking noise due to their density and mass. Aluminum and steel doors are both very durable and provide good sound insulation. Still, they will also be heavier than wood.
- Sliding, bi-fold, and pocket doors are not as effective at blocking sound, so these types are not recommended if you’re looking for a soundproof door.
- In addition to the type of door, you should also consider the thickness of the material. The thicker the material, the better it will be at blocking sound.
- Finally, look for doors with additional soundproofing features, such as rubber seals and weatherstripping, to reduce noise further.
