Frequently asked questions

What does sound resistance of 33dB mean?

The value of sound resistance refers to noise suppression by this value. E.g. a regular dishwasher in the household has the noise value of 43dB. A door with the resistance of 33dB transmits the noise of only 10dB to another room.

We have an old entrance door and the draught going through it is quite bad. What should I do?

In such a case it is worthwhile to replace the door and reduce heating costs of your household.

Are thermo doors used as the apartment entrance doors?

No, they are not. If you choose a SAPELI safety door of RC3 class as the entrance door, you will partially replace their function.
