Using double doors one of the best ways to close off one room from another and depending on the aperture or space within the wall that you have to work with they may well require a side screen to the left, the right or both sides of the double doors, the other option is to consider using doors from our Multifold range where there are numerous folding doors as alternatives and other sizes available.
The frames can be fitted to suit varying thicknesses of walls by adding "Ingoes", these are timber/wooden plates that are cut to suit the wall thickness less the frame thickness, for example if you have a wall that is 200mm thick and the double doors frame you have chosen is 110mm then you would require a 90mm ingoe or arrange for a plasterer to finish the returning wall as required.
