When buying interior doors, many people think, first of all, about the degree of their sound insulation to create a more comfortable atmosphere for all residents of the apartment or house. Today, the market is simply full of all kinds of entrance doors models, which are made using different technologies and from different materials and by itself that they differ in the level of their sound insulation.
For example, phylene doors, which are made of solid wood, delay the sound quite well. Basically, they do this at the expense of their mass, but you should not forget about design features, because the falses strongly affect the cross -country ability.
In addition, a polymer filler can be used to increase sound insulation in the design of the doors, which significantly increases the sound insulation of the door. Some manufacturers, if, of course, allows the design of the door, fill all voids with special cardboard, which in its structure looks like bee honeycombs. This technology significantly increases the sound insulation of the door.
The sound insulation of the doors made of aluminum profile depends on the noise insulation characteristics of the filler, which they are filled. The presence of glass or other inserts plays a great influence on the level of sound insulation of the door.
