Flush Door

Our flush doors are manufactured from selected hard wood timber with preservative treated and well seasoned. Due to more durable and highly dimensionally stable our products are used for interior and exterior purpose both. Not only our doors are structurally strong but also they act as good insulators against heat and sound.

 

DETAILS

 

CROSS BANDS
Cross bands are uniformly dried to the required moisture as per IS: 1141-1991 in thermic fluid drier. To make it stress free cross bands are tenderized.

 

ADHESIVE
Superior quality of phenol formaldehyde synthetic resin (BWP Grade) confirming to IS: 848-1974 is used for bonding 100% boiling waterproof.

 

PRESERVATIVE TREATMENT
To make our products termite and fungus resistance, timber and cross bands both are treated by fixed type of preservative chemicals as per IS: 401-1982.

 

CONDITIONING
To relieve external stresses during hot pressing special treatment to the flush door is given.

SPECIAL FEATURES :-

After processing we dip flush doors while in hot condition then stack it for minimum 12 hours before sizing. In lamination sponge spreads a thin layer of water over surface after hot pressing is done.
