Tighten up the tolerances for wood construction to match those for the masonry veneer. Design the wood stud backup to a deflection limit of L/720 to minimize veneer cracking. Use galvanized hardware (including screws) for masonry veneer ties to minimize corrosion potential. #STEM WALL FOUNDATION WITH BRICK VENEER CODE#
IECC requirements vary by climate, so make sure you understand local conditions and what energy code is relevant in your area.
#STEM WALL FOUNDATION WITH BRICK VENEER INSTALL#
If your construction project is subject to the International Energy Conservation Code (IECC) or the requirements of ASHRAE-2004 or ASHRAE-2007, you might be required to also install a continuous layer of insulation to this wall.
New requirements in energy codes may require that you use rigid insulation in the veneer drainage cavity when the structural backup is built of wood stud or steel stud. This phenomenon can reduce the insulating capacity of a wood stud wall by 40% and by 60% when Steel studs are used. Studs are denser than the insulation and the cold travels through the studs and ignores the insulation. Studs provide a direct thermal path through the wall and reduce insulating efficiency. Use insulation that is installed in the cavity whenever possible: it is nearly continuous and is much more effective than insulation installed between the studs. Sustainablility / Green Building Design. Renewable energy and thermal mass – up to 10 pts. Regional material (where applicable) 2 pts. Energy efficiency, thermal comfort and energy analysis – up to 10 pts. Thermal Mass Advantages of Masonry Walls. R-value: 16.2 with 6” fiber batt insulation Fire Endurance Ratings of Clay Brick Masonry. Check your local requirements – and save money by using normal veneer ties in areas of low seismic risk.Ģ hours (with 2 layers Type X gypsum board) When masonry veneer is used in areas of high seismic risk, veneer ties are required to attach to wire reinforcement embedded in mortar bed joints in the veneer. Joints: Concave tooled Regional Variations Mortar: Type N, Portland cement/lime, plain gray Veneer ties: Adjustable galvanized ties anchored to studs. Veneer: Cored modular clay brick 4" x 2-1/3" x 8" (nom.) Sheathing: 5/8” oriented strand board, nailed into studs.Weather resistive barrier over sheathing. There is a potential for mold growth on sheathing unless mold-resistant sheathing is usedīackup: 2" x 4" studs 16" on center. Interior surfaces (drywall) are prone to vandalism and damage in heavy traffic areas. If the wood studs rot, the structure is compromised Wood rots if water penetrates past the drainage cavity. 
Carpentry tolerances are looser than those for masonry – which can lead to conflicts during veneer construction.Multiple trades are involved, which makes jobsite coordination more difficult.Volatility of wood prices makes it difficult to predict final project costs.wood stud construction flexes more than the masonry veneer – this can lead to cracks developing in the masonry unless the studs are designed to strict deflection tolerances.Drainage cavity keeps building interiors dry.Many of the benefits of a masonry façade: durability, low maintenance, high fire rating, and numerous design choices.Looks like a solid masonry building but a wood stud backup system costs less.Choosing the Right Masonry System for your Budget.Use where budgets are more important than longevity.Single-family and multi-family residential, shopping centers and restaurants, low-rise construction.
