Before installing a door lining, you need to know its thickness

Before installing a door lining, you need to know its thickness. To calculate this, you can subtract the thickness of the door head from the height you want to line your door. Then, measure the length of the lining and mark it accordingly. After that, cut it to size and trim it shorter if necessary. But, make sure not to cut off too much wood, as this will ruin the lining.


106mm door lining is available in a range of sizes to fit most standard internal doors. It comes flat packed for easy installation and can be made to match various wall thicknesses. It is also available in a wide range of colours and staining options. You can purchase door lining online or in a local DIY store.

When buying door lining, you should make sure you measure the depth of the finished wall. It is common for the finished wall to be 100mm in depth, and you’ll need a door liner that is at least 106mm deep. It will need to be wider than the thickness of the timber lining kit and will leave 10mm of room on either side.


If you are planning to fit new doors in your house, you’ll need to line them with the correct lining. This is one of the most challenging tasks in home building.
