Windows might have some holes around them, especially the area where they are attached to the walls. Although these gaps may look tiny, they allow a lot of noise to penetrate your room.

Acoustic caulk can also be used to seal the small gaps on your windows. The process of installing is easy and quick. Make sure you clean the surface you are applying first.

Dirt and dust interfere with the elasticity and curing time of the acoustic caulk.

When the surface is clean, the caulk will adhere better than when it is dirty. The acoustic caulk is more durable than the regular caulk and can serve you up to three years.

It is designed to be flexible, which keeps it free from shrinking.
