DOOR FRAMES AND LININGS

Payne Carpentry have extensive experience in the many types of door frames & linings. To find out more contact us today.

WHAT ARE DOOR FRAMES AND LININGS?

Door frames are used for external doors, whilst door linings and casings are used for internal doors, and all form a frame to hold the door leaf in place.

WHAT IS THE INSTALLATION PROCESS OF DOOR FRAMES AND LININGS?

Door frames and linings are traditionally considered a first fix carpentry item that will be installed prior to plasterboard being fitted to walls and plaster being applied to masonry walls. However, some modern developments, especially those where wall finishes are dry lined, the timing of the frame & lining installation works may follow.

Door frames are generally constructed from a solid piece of timber that is machine worked to achieve its moulded and rebated shape to receive the thickness of the door. Whereas a door lining is a flat piece of timber with a smaller timber section applied to it known as a door stop. The doorstop is deliberately placed to receive the correct thickness of the door, resulting in a flush door and lining combination.

In general, a door lining will cover the full thickness of the wall it is fitted within and architrave mouldings will be applied to it on both sides of the wall. A doorframe, however, is of nominal size and is commonly set back from the wall face creating a reveal return each side of the frame.

Fire doors will require specific frames and linings regarding material thickness & compliance. Often a groove will be machined into the edges that surround the door leaf, the groove will receive an intumescent strip which will expand with heat to prevent oxygen from feeding an area of fire and prevent the fire from bursting through the gaps between the door and the frame/lining. Sometimes the intumescent strip will be fitted to the door edges.

Door frame & linings will be sized so the finished internal aperture is 5mm wider than the door to assist the installation of the door without excessive resizing works.
Regarding height, the jambs of the frame/linings (uprights) will be cut to length on site to suit whatever specific floor finishes will be applied to the sub floor, again omitting the need to cut the door for height.

Frames/linings will be fixed perfectly plumb and level within the structural opening, jambs will be straight and parallel and there are methods to ensure that the works are not twisted and in perfect alignment so that the door is flush to all edges when hung Packers & wedges will be used to achieve this of which will be hidden once the architraves are installed.

Fire rated frames/linings may require the gaps between the outer edge and the structural opening to be fully filled with a low expansion fire rated foam fill to prevent fire penetration behind the architrave.

Payne Carpentry are licensed to install fire rated frames, linings and doors, many warranty companies will insist such works are carried out by licensed operatives to ensure that procedures meet requirement.
