Barrières anti-rayonnement pour grenier : un guide rapide
Peut-être avez-vous pensé à installer une barrière anti-rayonnement dans votre grenier, mais vous avez quelques questions. Le coût initial en vaut-il la peine à long terme? Quels en sont les avantages? Quelles régions du pays sont propices à l’installation d’un anti-rayonnement? Comment puis-je m’assurer de l’installer correctement? Jetons un coup d’œil à quelques-unes de ces questions et voyons si un anti-rayonnement vous convient.
What Is Radiant Barrier Sheathing?
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 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.
Do You Need Radiant Barrier?
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 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.

How To Install Radiant Barrier
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.
