Residential HouseNetTM is easy to use. It requires no fasteners or adhesives, no special skill or tools. After the first one or two courses of bricks are laid, place a continuous row of Residential House NetTM in the cavity on the flashing against the back of the brick at the base of the wall. Flashing should extend to at least 6” above the top of the Residential HouseNetTM.

Mortar Net USA, Ltd. recommends a minimum 1” cavity air space for residential construction.
Mortar bridging can occur in cavities that are smaller. Should mortar bridging occur across the cavity space as the brick veneer wall is constructed, the mason should clean the mortar protrusions and bridges off the back of the bricks. Reasonable care must be taken to prevent excessive mortar droppings. Cavity should be no more than ¼” wider than 1.0” and 2.0” thick material, and 0.4” thick material should touch both the outer and inner wall, insulation, or filler used to adjust the cavity size.

Residential HouseNetTM is compressible to allow for variation in wall cavities.

Residential HouseNetTM must be used in conjunction with impermeable through wall flashings that are recommended by the flashing manufacturer for that use.

Residential HouseNetTM used in combination with fast acting weep materials such as Mortar Net® Weep VentsTM create a system for proper water drainage and ventilation.

Mortar Net USA, Ltd. does not guarantee the elimination of moisture problems due to other aspects of construction procedures such as rain soaked wall board, leaking plumbing, etc.
