What to put under lintel external reveal?

[WWilts]

Catnic type lintels for traditional cavity wall. Window openings. Exposed brick exterior.

 

Outer leaf, under lintel.

 

What do people put there?
Or do they leave the steel (and thermal bridge) exposed?

Is there a good looking version of jablite to glue on? or just insulated plasterboard?
Something else?

I used a PU glue and fixed a plastic 50 mil trim to match the frames

I am just going to leave mine bud - can't use insulated pb as it is exposed to weather and would melt.

 

Tbf - no-one but me would ever spot it tbh - you could always order up some upvc strips but it will look like a bodge and draw more attention than the bit of steel.

The thermal bridge is tiny - usually get left or if you really want to cover it you can glue something to it like @nod says

Separate lintels for me every time inner and outer alternatively check lintels which leave room for insulation in the head.
