Just wondering about wall insulation for a new brick veneer house...
1.5 rating pink batts to external walls already included as standard...
Is there any advantage in also placing sarking to external walls between frame and bricks?

As for shiny side out - The sun gets reflected onto their face - so they get double the sun for the day
Re the other stuff.
These links will help.

Antiglare reflective foil included in a brick veneer situation would be rated at R0.85.
It would be unusual not to include the foil to retain the wall batts to within the stud work.
RFL only has an R value when facing an air space such as in a veneer construction. i.e. in a weatherboard type construction its value is only as a sarking & has no thermal value.

I hope you have applied a house wrap or sarking to the walls as this will help prevent condensation, thermal bridging, improve the overall R value and in the summer reduce the radient heat into the living areas.

The more protection there the better. Just make sure it's not put up shiny side out. Brickies aren't real keen on that
You need an air gap on shiny side otherwise the radiant heat is conducted into the adjacent material. Therefore it should not press up against the batts.

Sounds unusual. I've seen sliding windows bind because either the lintel was undersized or in one case the sill trimmer was forced up because of shifting foundations. You…
