Sliding wall panels – If you want to create a new opening for a door opening in a brick wall First, you need to find out if there is a single skin (usually an inner partition) or double sided (outer wall) and if the wall is supportive. On load-bearing walls, you must install a piece or steel beam above the opening, on both the inner and outer skin (about a double wall). On a double wall you will also need to fit cavity closers (plastic best). The joint construction of a double wall would be brick on the outer shell and light blocks on the inner skin.
How to open a door in a sliding wall panels. Select the position on brick wall where the door is to be placed. Always measure the position of the opening from both sides, as well as from the top to the bottom. Remember – action twice cut once. Using water pass and chalk line marks two vertical lines on the wall (if it is an external shell wall, you only need to mark the inner wall). Connect across the top of the horizontal line to create the shape of the doorway. Allow enough extra height above and above the door frame size for the steel beam (if it is a supporting wall).
Using the drill and long masonry piece, drill one hole in each corner of the chalk line (top and bottom). Through to the other side of the sliding wall panels (both skins on a shell wall). Where the holes are located on the other side of the wall, go using a chalk line and water pass to create the horizontal and vertical lines to match the inside.
