flush doors for beautiful homes and offices
Yugal Plywoods’ Flush Doors are manufactured with best in class pinewood and well maintained in-house resin. High tech manufacturing facilities coupled with stringent quality control measures at each stage of the manufacturing process ensure doors which are sturdy, elegant and dimensionally stable.
Bonded with Boiling Water Proof grade, Synthetic Phenol Formaldehyde Resin {batch tested in our own hi-tech laboratories}, the doors are hot pressed under proper temperature and pressure to be de- lamination free. Thus our Flush Doors never bend or warp under normal conditions.
