Innovative manufacturers like Norbord that think outside the box have flipped the structural sheathing panels for vertical installation and increased their height. Longer wall sheathing like TallWall enables an overlap at the joists which eliminates hinge points to increase wall strength. Longer sheathing also reduces the number of seams which improves energy efficiency and makes for a stronger, smoother, flatter wall.
A common summer problem is condensation on walls around AC air vents. Moisture is insidious and, once allowed to enter wall structures, can result in damage, mold and mildew. While quick-fix solutions may provide cosmetic relief, it is best to spend the time and money to ensure that moisture is not seeping into your wall structures.
As construction costs increase and building codes demand more effective building envelopes, construction professionals are looking to taller wall panels to fill in the gaps. OSB wall panels already make for a sustainable and cost-effective option but with longer length OSB wall panels, the efficacy of the building envelope is increased by creating fewer seams while costs, waste and installation time are reduced.
An effective building envelope is a combination of insulating building materials and a reduction in air leakage. This reduction can be achieved by using taller wall sheathing panels and through effectively sealing air leaks. When determining which air leaks construction professionals should focus on, Dave Wolf from Owens Corning Science and Technology has conducted a study to see which leaks require the least effort and sealant and provide the highest returns in building envelope efficiency.
