Hi I am installing a 3metre wide folding sliding door into a rendered cavity wall. The lintel is a catnic cavity lintel. The height of the frame is 40mm less than the opening. My intention is to attach a 40mm thick board to the underside of the lintel which I can then attach the doorframe too. My question is about how I should attach the 40mm board to the lintel? Can i bolt through the lintel into the concrete blocks behind or should I use adhesive? If adhesive then what kind? Many thanks for your help Chris | ||

I'm not sure you need to do this. Consider the situation if the door WAS the same height as the lintel opening - you wouldn't then normally attach the frame to the lintel above it. You'd attach it at the sides by frame fixers into the outer skin of the cavity. Your difference is that you have a 40mm gap in the required height of the frame - I'd just screw and glue a 40mm wide piece of wood to the top of the frame. | ||

Hi Buildersmate I was wondering about that but I think that in this situation it is different because the top rail is so long and is supporting the weight of the sliding doors which hang from it. I think I am just going to screw into the lintel with self tapping steel screws - unless anyone says that this is a bad idea! Thanks for your comments Chris |
