Windows, brick veneer, exterior insulation

Alan Afsari | Posted in General Questions on

Does using brick veneer better lend toward Innie or Outie windows?

Climate zone 5
2×6 studs
2″ exterior rigid insulation

My thinking is that outies (from the studs) would end up with a generous sill inside and out.  Innies will have a very generous exterior sill…

the bricks are 3-5/8″ (front to back).  planning lime stone sills

I have spent time looking for details – I haven’t found any with both brick and exterior insulation.

Thanks,
Alan

    Alan,
    The detail below comes from the GBA detail library. If you become a GBA member, you'll have access to all of the details in this library. The rigid foam in this detail is relatively thin, but the detail shows the principles involved.

    This is more of an "in-betweenie" window than an innie or an outic.

    Link to detail.

    Thanks Martin!

    I remembered you mentioning "in-betweenie" windows in your blog "‘Innie’ Windows or ‘Outie’ Windows?". I don't see it in your blog "Where Does the Housewrap Go?", but I assume the Housewrap goes over the exterior foam and under the sill flashing.

    I thickened the foam to 2" in the attachment...

    Alan,
    The GBA site has had problems with uploaded images recently -- neither your upload nor my upload was successful. We're working on solving the technical problem.

    In the meantime, here's my advice: If you're using brick veneer and rigid foam, the WRB (housewrap) belongs on the exterior side of the rigid foam. That way, it's easier to integrate the WRB with the flashing.

    For more information, see "Flashing Brick Veneer."
