CERTIFICATE OF SOUNDPROOFING

Certifications of soundproofing products

Always aiming to improve and upgrade the products, our company collaborated with the National Technical University of Athens, to certify a series of its wooden frames. The tests were carried out in the University's specially configured acoustic laboratories for our new CLIMA cross-section (applies to frames and exterior door) as well as the two interior door cross-sections.

Our company maximizes the acoustic comfort in every space from extraneous noises, offering superior certified sound reduction of 43dB level in our new CLIMA section. Below are all the measurements from our products:
