Maybe you've been thinking about installing a radiant barrier in your attic but have a few questions. Is the upfront cost worth it in the long run? What are the advantages? What areas of the country are appropriate for a radiant barrier? How do I make sure I install it properly? Let's take a look at a few of these questions and see if a radiant barrier is right for you.
If you live in an area that experiences higher temperatures, you most likely also experience higher cooling costs. That's due to the sun's radiant energy hitting the shingles and transferring heat into the attic space. LP® TechShield® Radiant Barrier—the first OSB radiant barrier in the industry-is made by laminating a thin, durable sheet of aluminum to LP OSB Sheathing. The purity of this aluminum means the radiant barrier prevents heat absorbed in the roof sheeting from radiating into the attic, blocking up to 97 % of the radiant heat in the panel from emitting into a home's attic. According to the U.S. Department of Energy, the radiant barrier’s ability to lower heat transfer keeps attic spaces cooler by up to 30° F, which can help curb energy costs. This can also help improve the efficiency of in-attic HVAC units and reduce the tonnage of the entire system. Additionally, the patented VaporVents™ technology that comes with LP TechShield sheathing has small incisions along the foil that allow for any trapped moisture to escape from the panel before and after installation.
As average temperatures around the country continue to climb, the thought of using a radiant barrier to cool your attic space may start to make more sense. Whereas you can almost make a case that you can use it just about anywhere, there are areas where using a radiant barrier makes the most economical sense. Typically, southern states where summers are more brutal make the most sense. Additionally, many of these states also have increased humidity. In these states the patented VaporVents technology that comes with LP TechShield provides an extra benefit. If you do not live in one of these hotter climates, then installing a radiant barrier in your attic is probably not the right option for you.
States Where Radiant Barrier Is Popular:
If you are looking to lower attic temperatures, save money on energy costs and live in a region where installing radiant barrier makes sense, it's time to install. Unlike spray foams and after-market radiant barriers, LP TechShield Radiant Barrier is rather simple to install. When working with it, you'll find that it cuts and installs like any other traditional roof deck sheathing products. You won't be required to use any special tools, and there is only one special instruction-always install LP TechShield foil down. This is key to protecting your roof and for warranty reasons.
Why Foil Down?
Even though the foil is reflective, it's not what makes a radiant barrier work. As the sun beats down on the attic, the foil absorbs the heat and allows very little of the heat to emit into the attic.
Besides being able to protect the home from the effects of radiant heat, LP Structural Solutions has a full portfolio of products proven to defend your build. Take a look and see what other solutions are available to help you build better and more efficiently.
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 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.
