Can TallWall help decrease wall air infiltration?
Yes, installed vertically TallWall eliminates horizontal joints and that means up to 60% less wall air infiltration and better indoor air quality (air leakage increases energy consumption and reduces indoor air quality). Using TallWall means less job-site waste, less handling, less labor, and less metal in every house.
Is TallWall CARB exempt?
Yes, TallWall is CARB (California Air Resource Board) exempt and does not contain any urea-formaldehyde resins.
Can using TallWall and cutting out window and door openings make the wall stronger?
Yes it does and it also reduces the number of joints and that reduces the air leakage. This also generates less waste with less labor. See the APA Full-Scale House Test Project report Form #3D007.
What is special about TallWall and why does it work?
TallWall is engineered to be installed vertically on the walls. The longer length panels cover from the bottom to the top plates or beyond.
Were any independent tests completed?
Testing on the additional benefits were completed at Virginia Tech and the Home Innovation Labs.
Is TallWall accepted by the building code?
TallWall is a structural OSB panel and is accepted by North American building codes including the Florida Building Code.
Why is blocking eliminated?
Some building codes require all horizontal joints in the wall sheathing to have solid blocking. TallWall panels are the right lengths for taller ceiling heights or mid band connections with one structural panel – no horizontal joints – no blocking required.
What does Exposure 1 rating on the grade stamp mean?
Exposure 1 rating means that the panel uses a waterproof resin. It does not mean the panel is waterproof but rather that the panel will withstand normal delays in construction without affecting the structural properties (strength) of the panel. All TallWall panels carry the APA, The Engineered Wood Association, grade stamp.
How much money can I save using TallWall?
This will vary by the size, style and location of the home. Here are a number of areas where TallWall can reduce your costs and construction time.
- Fewer joints make it easier to meet energy codes
- No lumber for blocking to buy and install – Material and labor savings!
- No panels to cut and install as filler strips – Labor savings!
- Less waste – Less cutting and less chance of errors means savings!
- Flatter, stronger, stiffer and straighter walls – Fewer call backs mean savings!
- No blocking means wall cavities are fully open and allow full insulation to be installed – Trades work faster and more efficiently!
Where can I buy TallWall
TallWall is available from your local building supply dealer. Ask for it by name. If your dealer or design professional requires assistance, have them contact us directly or advise us and we will contact them.
Are there special requirements for a stucco exterior finish?
If Stucco is the exterior finish siding please refer to the APA (The Engineered Wood Assoc) Q370 for structural sheathing thickness and grade recommendations. You should also refer to applicable local building codes for proper stucco installation over OSB or plywood sheathing.
