How do You Keep Brick Veneer Construction Airtight?


How do you keep brick veneer construction airtight and well insulated when the ties from the brick to the wall studs puncture the rigid foam insulation board and the building's vapor barrier? -- Harold Murray, Bowie MD


Foam board insulation (C) Arlene Puentes Daniel FriedmanWith a high-density rigid foam board insulation such as extruded polystyrene

or foil faced polyisocyanurate insulating board
(see POLYISOCYANURATE FOAM and IAQ), the brick veneer wall ties can be placed on the surface of the foam sheathing and nailed through to the wall studs.

Our photo (left) of foam insulating sheating board was provided courtesy of Arlene Puentes.

This is in accordance with FHA Bulletin 71 for single- and two-family residences.

In especially windy conditions, it may be advisable to increase the number of brick veneer wall ties or use higher-density insulation.

Another option is to nail the ties directly to the studs between each 24-inch course of rigid insulation board.

In any case, the vapor barrier on the warm side of the building wall will not be affected.
