When you're working in an area of the country that is prone to high winds-or even hurricanes-structural strength for your builds is critical. If severe weather occurs, choosing the best sheathing for homes in hurricane areas can help mitigate damage and potentially reduce the extent of rebuilding necessary.
LP WeatherLogic® Air & Water Barrier serves as water-resistive barrier sheathing and, because it is classified as Structural I sheathing, it also adds structural strength. Let's examine why LP WeatherLogic panels can be a great fit for builders in high-wind and hurricane areas.
Builders are likely to have concerns about high winds and hurricanes in a couple of key areas. The obvious regions are along the Atlantic and Gulf Coasts, where there are numerous hurricanes throughout the hurricane season. However, there are other regions that can sustain very high straight-line winds in the range of hurricane force wind speeds, primarily along mountain ranges.
In these regions, high winds can create substantial lateral-i.e. horizontal-loads on a structure. The winds push on the windward-or upwind-walls and create suction that pulls on the leeward-or downwind-walls. These loads are additive and require shear walls to transfer those loads down to the foundation.
With that in mind, air- and water-resistive barrier sheathing with more than the standard level of structural strength may be helpful for homes that are prone to high winds.
Plywood sheathing and OSB products, such as LP WeatherLogic Air & Water Barrier, can both be used in areas prone to high winds and hurricanes. Code shear wall tables provide more information on each product's performance category (nominal thickness) and grade (Struc I sheathing, for example), so builders can make the best choice for each project and its specific weather considerations.
In some areas, materials discussions have made their way to city councils for official votes on codes and approved building solutions. Check out this case study from Galveston, Texas, and read more about how builders can balance resilient design with building codes in hurricane zones.
Classified as Structural I sheathing, LP WeatherLogic panels boast added structural strength for both walls and roofs. The WRB membrane added to the OSB sheathing provides moisture resistance, making it a complete exterior option for moisture management.
Structural I sheathing is a PS-2 grade of wood structural panel that has higher cross-panel bending and racking/shear strength than the conventional sheathing grade. In high-wind zones, this affords the designer an increased shear wall strength to resist the lateral loads induced on a structure.
LP WeatherLogic Air & Water Barrier provides more than the structural strength you'll need for building in a high-wind zone. It also offers a proven moisture management system and easier installation. This is due to the integration of the sheathing panel and water-resistive barrier (WRB). Instead of installing sheathing and housewrap in separate steps, LP WeatherLogic panels allow you to complete those steps at the same time.
Can a wall protect from wind? Sometimes, hurricane winds are too strong and damage is inevitable. But when you build with LP WeatherLogic Air & Water Barrier, you can take the right step toward keeping your build as strong as possible.

New to the LP® Structural Solutions portfolio, LP® NovaCore® Thermal Insulated Sheathing is a dual-layered wall panel design to protect structures against heat loss and gain. It combines resilient OSB sheathing with XPS foam to provide continuous insulation without the long-term R-value deterioration associated with other foam insulation products.Continue Reading
With an abundance of inspiration at their disposal, clients may have design goals that exceed their budget. We talked to building professional Kyle Stumpenhorst to get his tips for helping clients achieve their goals without breaking the bank.
With today's hot housing market the last thing you want to do is stop, backtrack, and address a customer callback. In any economy, callbacks in construction cost money and time-time you may not have. Some builders are dramatically reducing customer callbacks by choosing building products that promote greater performance.
In recent years, the construction industry has seen an upward trend when it comes to spending on new construction with forecasts of 2,5 trillion U.S. dollars in 2025-but the increased numbers don't necessarily point to industry growth. With labor and supply chain shortages continuing to increase, there has been a significant increase in the cost of such goods and services.
