In respect of the Canadian National Building Code, soundproof entry doors in lodging units must have a minimum index of sound transmission class of FSTC 45 on the job.

Insonorisation GLH Inc. has designed and constructed a soundproof door since 1988 which permits the depassing of the FSTC 45 legislation. The new conception of our door in effect authorizes an index of FSTC 48, as it is demonstrated in the various graphic tables.

Four patented products are currently available

• the acoustic flooring
• the soundproof door
• the soundproof electrical box
• ready-to-install for the sound insulation of cabinet "toilet bowl"
