Aluminum inspection door acoustic 34dB 400x400x25

The door is made of special aluminum profiles welded into an outer and inner frame. The complete assembly is joined by a solid hinge, thus allowing the door leaf to be opened when needed. The outer frame of the door is fitted with a rubber seal that prevents the passage of air. The infill of the inner frame consists of a blue acoustic board, fixed using self-drilling screws. In order to increase acoustic resistance, the back of the board is additionally fitted with galvanized sheet 1 mm thick.

The door was tested for sound transmission according to standard ČSN EN 717-1

Main advantages of the model:

• Welded frames

• Easy-to-open push lock

• Acoustic resistance certificate up to 34 dB

• Variant option for ceramic tiling

• Firmly anchored inner frame

• Variable dimensions

Comfortable opening and closing is guaranteed by US push locks located on the outer frame. Pressing the inner frame board at the lock point causes the latch to click out or click in.

Although the outer frame is prepared for installation into a plasterboard panel, the certification is also valid for installation into a masonry wall.
