Door frame types
Door frames are an important concern when it comes to security and
are often overlooked. No matter how sturdy the door or secure the
locks, if the door hinges have been drilled into a flimsy frame it
can be kicked down in seconds by someone determined to do it.
Because most locks and dead bolts protrude into the door jamb and
rely on it for support, choosing the right frame is a vital part of
ensuring that your doors are securely attached.
What materials are available?
Door frames are most commonly made of wood; this is usually the
fastest and cheapest material for framing doors, but wood can be
vulnerable to splintering and cracking under pressure, and weakens
over time. Some door frames have a reinforcing steel overlay which
prevents this from happening, but other materials such as uPVC,
fibreglass and aluminium or even a composite blend of wood and
resin will all achieve similar effects and make the door frame more
Some doors are sold pre-hung - that is, already attached to the
frame via hinges, for easy installation and a close fit.
What different shapes & types exist?
A basic door frame consists of two jambs running vertically
parallel on either side of the door, with the lintel forming the
crosspiece at the top and the sill forming part of the threshold on
the floor below. No matter what the shape of the door, even if it
is non-standard, the frame will need to provide a seal for the door
when it is closed, so the frame will be designed with that
primarily in mind. This can compromise stability somewhat,
especially if the door is an uneven or irregular shape.
What difference do various shapes and materials make?
Different shapes and materials can alter the strength of the door
frame, for better or worse. Selecting a material which will not
only look good over time but will hold up under sustained pressure
is worth spending the additional time and money on. Rectangular
door frames offer a strong support structure, and changing or
adding additional angles to a frame may add weak points which can
One big difference that different materials can make is their
ability to transfer heat into and out of a house. Metal, for
example, is an excellent conductor of heat and can easily act as a
very effective thermal bridge (a weak point through which you'll
gain or lose heat). Metal door frames can be made with thermal
breaks though, which will help to prevent this while still giving
you the look you want. Timber, by contrast, is a fairly poor
conductor of heat and does a pretty good job of keeping heat in or
out of your home - as do uPVC, fibreglass and similar materials.
