In noisy workshops or in locations where there are particularly noisy machines, the critical areas of noise-proofing are usually the entrance ways for personnel or materials, and the windows, if present.

The Alfakel series “A” sound-insulating gates and doors are the best solution for noise remediation of all access points, and because of their flexibility they can be used in all industrial, commercial private or public activities sectors.
