DOOR CORE

The Shadmaster substrate comprises a solid timber core of narrow laminated spruce sections faced on both sides with chipboard, providing outstanding stability and accuracy. It also gives excellent fire resistance, sound insulation and mechanical strength.

Core production
Sheets are peeled from the log following the annual growth rings, then bonded together and sawn into strips. This gives consistent and balanced grain orientation which is inherently stress-free and allows behaviour to be confidently predicted. The uniform grain orientation and narrowness of the strips minimise distortion during a fire – a critical factor in achieving fire performance since it avoids the risks of gaps developing between the door and frame. The inherent stability eliminates core shadow and provides a ripple-free surface. Stability is guaranteed up to 3048mm x 1524mm.
