Definition
Internal timber doors consist of the leaf, frame, architraves and hardware (hinges, lock and handles). The leaf is solid timber, or a solid core faced with timber veneer or HDF, and fire doors carry a rating for their resistance time.
Why it matters on a project
Doors are used every day, so a weak core or poor hardware shows quickly. Solid-core doors insulate sound far better than hollow ones.
Measurement and pricing
By number for each size and type from the door schedule, including frame, architraves and hardware, or with hardware as a separate item.
Common mistake
Fitting doors before painting and flooring are finished, so they get damaged or the floor level under them changes.
Frequently asked questions
What is the difference between solid and hollow core?
Solid core is heavier, better for sound and more durable; hollow core is lighter and cheaper.
When do I need a fire door?
On escape routes, plant rooms and some corridors, per the fire code and safety design.
