Brick Masonry Techniques Part III

New Home Construction

FLASHING 

At Base of Structure    

Flashing at seven different locations according to code

Base flashing around entire building and foundation

20-30 mil synthetic vinyl flashing

Place flashing all the way to face of brick veneer

Overlap and seal flashing at each corner; failure to do so can produce a leaky wall at the corners

Window Head & Sill

Flashing required at head and sill to meet code / Weep holes at head and sill as well

Allow +/- one inch extra flashing at each end to form dam

Angle iron should extend four inches past rough opening on each side

Bottom flashing should be installed before window is set

Cut top piece of house wrap off flush with opening

At head, slide flashing inside of house wrap to promote shingling action

Bay Window

Three pieces of eighteen gauge galvanized steel flashing 

Greater than 7/12 but less than 12/12, weld stops every two feet on angle iron to support the load
