A door that's been fully prepared for installation. This means painted, varnished, waxed or whatever your chosen finish is. With a pre-finished door, you can just pick your hardware and you're ready to go.
An unfinished door is not waxed, varnished or painted when you buy it. So, you'll have to apply the finish yourself.
Primed doors are already treated with a base coat of paint called primer. However, they need to be painted before you can hang them.
A door frame consists of many elements. Parts, such as door lining/casing, architrave, and sill, all form to create a door frame.
The lining hides the gap between the wall and the door.
Thermal bowing will normally occur when one side of a door is too hot, but it can occur in reverse, under extremely cold conditions. When there is a large temperature difference, the exposed surface of the door can swell/expand on the heated side, causing the door to bow.
Stiles are those vertical components on the outside of the door – on both sides. It's where you will find the lock, latches, and whatever hinges your project requires. Rails are the horizontal sections of the door panel at the top and bottom of the door.
A thermally broken door uses thermal breaks to keep exterior temperatures from entering the house. The thermal break material is placed inside the door's structure, creating a thermally insulated barrier. It also prevents heat loss, an essential feature for extremely cold areas where heating is needed for long periods.
There are five main instances when fire doors are required as per building regulations.
Any building over 2 floors requires fire doors to be fit at each stairwell.
Any door that is attached to an integral garage from a house, needs to be a fire door.
Loft conversions require them as per building regulations.
Fire doors must be installed in all non-domestic buildings.
They are also a legal requirement in residential flats and houses with multiple occupancy.
However the guidance does state that fire doors leading to an attached or integral garage, must be fitted with a concealed closer.
Apartments
Fire door closers must be installed on the fire entry door to every apartment or flat, fire and smoke resistance tested to EN1634-1.
Common corridors connecting two or more storey exits must be separated by a self-closing fire door. Similarly, a dead-end portion of a corridor should be divided from the rest of the corridor by a self-closing fire door and corridors more than 12m long should be sub-divided by self-closing fire doors.
Residential Buildings
Residential buildings, such as hotels, care homes and student accommodation require CE marked self-closers to be fit on all fire doors, (unless specifically exempt, for example a cupboard). Corridors over 12m long should be separated by self-closing fire doors too.
Dependent on how long it’s tested for, depends on how long it lasts
FD30
FD30 fire doors have been tested in a fire for 30 minutes and therefore have 30 minutes integrity in the event of a fire.
FD60
FD60 fire doors have been tested in a fire for 60 minutes and therefore have 60 minutes integrity in the event of a fire.
Our unfinished doors can be painted or stained at home as long as our finishing guidelines are followed.
