LP Techshield® OSB
Here in the Northwest, we are accustomed to the rain and cold. Winter brings cold temperatures and cold homes, increasing the monthly cost of heating. But being accustomed to something does not make it acceptable. With LP Techshield® Radiant Barrier OSB distributed by IWP, you can have a home that traps in heat and keeps out the cold. With an advanced, patented post-lamination foil incising process, LP Techshield reduces energy usage in both hot Summers and cold Winters, along with improving the overall efficiency of your air conditioners and duct systems.
