Laboratory tested sound absorbing doors

The strength of the DOORTAL acoustic door sets is due to their steel box section frame as well as 1.5 or 2 mm steel on the leaf and strong certified hinges. They come with a 10 year warranty.
These acoustic door sets have been designed with a slim threshold (12 mm thick) as standard but are also available without a threshold bar by using an automatic drop seal system. This facilitates access for disabled persons and wheeled equipment, or simply offers improved aesthetics.

The PHONIPLUS acoustic doors have all been designed and laboratory tested following the exclusive « ChronoFIX® » concept, which means the doors are very easily fitted by screwing the frame in place and doing a silicon seal on each side. As there is no concrete casting, the door sets can be mounted in any support wall: concrete, metal structure, wood…

The rubber seals are specially designed by DOORTAL to adapt to its acoustic doors. The material composition as well as the shape of these seals ensure the needed elasticity to prevent air leakage even in case of imperfect evenness in view of an ideal sound absorption.
