Wooden Fire Door

We are dealing in wooden fire door
Wooden fire rated doors are not recommended for fire ratings of 60minutes and above as per the international standard.
Wooden fire rated doors are not consistent on performance and hence the core used plays a vital role.
The minimum door thickness recommended is 60mm
The wooden fire rated requires intumescent seals and fire retardent paints as a protection material.
The quality of wood may not be consistent through out the building and hence the relevant performance
All hardware provisions need to be protected with intumescent strips as the material rigidity is lost due to cutouts on the door leaf
Requires high level of maintainance as the wood being a organic material always tends to contraction and expansion
There are limitations on door sizes and vision glass as the rating goes beyond 60minutes
For all wooden fire doors the provision for door hardware has to be factory finished and fitted as a assembly to ensure the required rating and guarantees. However it is not followed in our working conditions and left to the installer at site
True wooden fire doors are very expensive because of the core
Limited finishes
Can generate Toxic gases if the core or the surface material is not appropriate
