Wooden doors
Timber doors not only look great, but they're also solid and sturdy and one of the best front doors for security.
When we say timber, we mean a heavy, solid hardwood door of at least 44mm thickness.
The strength of any door usually comes down to the quality of the lock and the frame - a solid wooden door can still be kicked in if it has a flimsy latch style lock or frame.
The superior style of lock loved by insurance companies is the five-lever mortice and this in combination with a solid frame is going to make it hard work for a burglar to jemmy open. It can't be kicked through, shoved with a shoulder or smashed open.
The only drawback of a timber door is the regular maintenance needed to retain the integrity of the materials and remain solid and impenetrable.
