Flush Doors
FLUSH DOORS
Flush doors refer to a class of Solid core doors that are completely filled with wood or wood composite materials. Solid core doors make use of an engineered wood core which completely fills the wooden frame. The door is then provided with a veneer on both sides of the core. The solid wood frame along with solid wood composite core provides high structural integrity and robustness. There are many variants within solid core doors based on the solid core used, veneer used etc..
The core used may be particleboard, fiberboard or blockboard having its own unique advantages. For example blockboard has higher bending strength, less manufacturing cost and time while particleboard provide better material distribution and is an effective alternative when appearance is less important. Fiberboards have advantages like smoother surface, ease of machinability, low cost and easily available raw materials.
Borotik gives unmatched assurance on the quality of our doors as they are carefully manufactures under controlled environment using sophisticated equipment. Our Danish technology chemical impregnation and seasoning makes our doors superior to other low quality products in every aspect.
