• Soundproof

    Behind each of our doors is an innovative idea, state-of-the-art technology, and a team that strives to unite the strength of steel with the power of design.

    Soundproof

    Soundproof doors and frames are necessary in many commercial buildings, such as auditoriums, offices, hospitals, schools, and apartment blocks. They limit the intrusion of noise into a room and ensure both quiet and privacy.

    DE LA FONTAINE offers a soundproof opening with an STC rating of 47, in compliance with the following standards:

    • ASTM E90 (Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements).
    • ASTM E413 Classification Standard for Rating Sound Insulation

    This rating is evaluated according to the operable method. The opening includes the frame, the door, and the hardware; each of the components is factory pre-assembled. This process allows us to ensure that when the opening is installed on the jobsite in compliance with the installation instructions, it will meet the required rating.

    The maximum dimensions for this opening are 4' x 8' (1219.2 mm x 2438.4 mm), with a door thickness of 1 3/4" (45 mm).

    We can also provide a steel door only, manufactured with a soundproof core. This door, evaluated as a (non-operable) panel, achieves different STC rating when used in conjunction with hardware supplied by Zero International.

    Based on acoustic performance tests of Zero International and De La Fontaine products, it is both realistic and reliable to use the final results with confidence. Please refer to the document below for more information on our products and the soundproofing ratings available.
