A composite door is made from multiple materials to provide excellent strength, insulation, security, and durability.
Built from up to 17 layers of laminated solid timber, Fortrezz Doors are 10% thicker than your average door, with a unique and unequalled 48mm-thick cross-bonded, veneered and laminated solid timber core.
The laminated veneered lumber (LVL) construction delivers unparalleled strength and dimensional stability. The engineered make up comprises cross-bonded veneers that greatly enhance lateral stability and stiffness. The combinations of all these elements make this a natural choice for high-security Composite Doors.
Also available as a Stable Door.
The Fortrezz comes in a range of standard colours, shown below. You can also specify white on the inside of your frames and a colour or woodgrain on the outside.
Dual-colour is a popular choice and reflects traditional frames where the outside is painted a different colour to the interior, allowing for greater flexibility in interior decorating.
