Timber Door Jambs

Innovative Prefinished Timber Door Jambs

Doors, as simple as they seem to the common person, are actually pretty complicated piece of mechanism. It comprises of multiple different parts — one of which, is the ‘door jamb’.

Timber door jambs are posts which stand vertically on either side of the door frame, or even a window frame. You can have partial view of timber door jambs when your door is open or closed, else, they are not visible.

Timber or hardwood door jambs are there to take the weight of the door, as well as keep the rest of the door’s frame square and stable. The hinges are affixed to the jamb on one side of the door, while the bolt passes through the jamb on the other side.

Timber door jambs, sometimes referred to as “door legs”, aren’t just for standard, single doors — they also the same purpose for double, folding and sliding doors.

Hardwood door jambs cannot be affected by temperature because wood have high R-values. They are also less prone to condensation since they do not conduct heat and electricity. Unlike metal, timber door jambs can still be altered easily, have no risk of rusting, are more resistant to air and wind due to minimal joint in frame and shutter and can be painted or polished in any shade in the future.
