Hi everyone.
I've just fitted an electric roller shutter door to my garage to replace the old up and over. Now I haven't actually removed the old up and over door yet (the two doors can open and close independently of each other).
In order to maximise head height under the lintel, I've fitted the roller door on the inside wall of the door frame. The original up and over sits within the door frame.
When I remove the old up and over door and the wooden frame around it, it is going to expose the end of the internal and external blockwork. In other words, you'll be looking at the end of the inner thermolite block, the outer brickwork and the cavity between the two layers.
On the upper face of the door aperture (if you look up) you'll be looking at the perforated steel catnic lintel.
I obviously want to cover this aperture to neaten it up and to keep the cavity dry - but I don't know how to do it.
I'm assuming I use a uPVC facia board or soffit. But I don't know whether to cover the ends of both types of block/brickwork and the cavity with a single uPVC piece, or whether to just cover the thermolite and to leave the brick exposed. I also don't know how these things are fastened to the wall or if I should cover the steel lintel too.
There is very little information online that I can see, so would welcome any pointers on materials and techniques.
I've attached a couple of pictures, in the second one - if you look above the wooden frame, you can just see the red brick-to-cavity-to thermolite block (white painted) transition that will be exposed when I remove the old door frame.
Thank you very much.
