Lintel projection for Bell cast above window.

[barrydoran]

Hi, I'm putting a set of UPVC Folding Sliding doors in an external solid wall which is currently rendered.

The old render is coming off as I intend to have the whole house re-rendered.

As the new doors will be lower than the current window, the question is what type of Lintel should I use. Currently there is only a 3"*8" ( guessing ) wooden lintel on the inner course with the outer courses sitting directly on the window frame.

Steel lintels for External Solid walls appear to be for a fair faced brick finish, i.e. they have the small downward lip on the front edge. ( eg catnic cn81b)

Wouldn't this look odd with a rendered finish using a stop bead to form the bell cast above the window? Or would you simply have no bell cast?

The alternative I guess is to use a concrete lintel, but the opening is 2440, so lintel would need to be 2750. Can you drill into concrete lintels to support the frame at the top?

Alternatively I could set the Steel lintel forward so the lip projects past the brickwork to be used as the stop for the bell cast.

Whats the normal solution to this?

Thanks.

Barry.

Hi Barry,

i'm no expert but from you say i'd have thought concrete was the way to go.

but wait until some of the others chime in.

a type c robeslee precast concrete lintel is what you would be looking to use.

which can also be drilled into.
