Installation of door frames

When embedding new door and window frames in the openings with polyurethane mounting foam, we must not forget to use struts. Well, the intumescent assembly foam can deform the door frames. Installed three struts evenly at the height of the door will protect against this deformation and allow the leaf to be properly closed in the frame after removing the struts and allowing the foam to solidify. Remember to put washers under the struts, e.g.. made of soft wood.
