Birch Acoustic Fire Door Blanks

Superior door blanks reaching -38dB (fully operational)

​​​​​​​​​​​​Metsä Wood's birch acoustic fire door blanks are manufactured from Finnish birch plywood​​​​ using cross-bonded 1.4 mm thick veneers. The panels are sanded on both sides and their surface is smooth, hard and durable. Birch plywood is characterised by excellent strength and rigidity-related properties.

Birch plywood has good resistance to humidity and is easy to machine and reprocess. Birch plywood can be further processed using different types of veneer/overlay. The properties of the panel’s surface can be improved or the pattern on the panel surface altered, depending on the intended application. The coating technology used in our mills represents the highest quality in the field.

Metsä Wood's birch acoustic fire door blanks have now been fire tested, with and without glazed openings, to European Standards* (EN1634-1) and are available in industry standard 2135mm x 915mm size for FD30 (1/2 hour) and FD60 (1 hour). Our acoustic fire door blanks are supplied calibration sanded and unlipped, ready for further processing.
