Lincoln Oak Internal DoorThe Lincoln is a three-panel oak door with clean, classic proportions that settle easily into a hallway, bedroom or living space. It is one of our modern oak internal doors, understated enough for a contemporary home yet at ease in a traditional room. The door is faced in oak veneer over an engineered solid core, so the three-panel design comes with natural oak grain and warmth.It is supplied unfinished and ready to hang, in a range of standard sizes at 35mm and 40mm thick, each with a generous trimming allowance. The solid core makes a more substantial, better-insulating and more stable door than a hollow core, and it sits neatly against oak skirting and architrave in a matching tone. The veneer is FSC certified, with a 10 year guarantee against manufacturing defects.The Lincoln is part of a family, so you can keep one look through the house: alongside this panel door there are prefinished, glazed and FD30 fire-rated versions for the openings that need them.It hangs on standard hinges and takes a lever handle, so you can match the ironmongery from our door handles and hardware.Being unfinished, every face and edge should be sealed before use. A suitable hardwax oil such as Treatex is all it needs; our door treatments cover what to use, and the maintenance guide explains keeping it topped up.Key Product Information Three-panel design with clean, classic proportions Oak veneer over an engineered solid core Supplied unfinished and ready to hang; seal all faces and edges Prefinished, glazed and FD30 fire-rated versions across the range FSC certified oak veneer, 10 year guarantee
