DURODOOR - Flush Doors are made with best quality kiln seasoned timber with a 3" frame all around. In addition cross ply layer on top is made with hand selected tropical hardwood veneer followed by a double pressing technology that gives these doors their unmatched strength.
DuroDoors can be veneered, laminated or even straight up painted giving complete versatility. If you require Single Leaf / Double Leaf or vision hole, we can provide all of them.
Internal batons and each layer of core are composed to ensure a gapless construction through and through thereby increasing the durability of each DuroDoor.
DuroDoors have a high vertical load bearing strength making it ideal for Doors - Main or internal.
