How to Create a Tight Building Envelope

Check out how the LP WeatherLogic® Air & Water Barrier system contributes to a tighter building envelope and a more resilient home.

LP WeatherLogic® Air & Water Barrier Installation Process

Learn the basics for installing LP WeatherLogic® panels to help you get started.

LP’s Proprietary Water-Resistant Sheathing Material Explained

To create a Structural I OSB panel, LP’s innovative manufacturing process combines wood strands oriented in cross-directional layers with waxes and resins for greater cross-panel strength and stiffness. Then, to create LP WeatherLogic® panels, an integrated, water-resistive overlay is added, completing an integrated exterior sheathing panel that provides both air and water protection. Rated for both wall and roof applications, the system eliminates the need for housewrap or roof underlayment (in most cases) while providing the increased capacity of Structural I sheathing.

LP WeatherLogic How Its Made

Moisture Management Technology

Protect what you build. LP WeatherLogic works to keep water out and energy in with an integrated, water-resistive overlay. The panels provide permeability and allows moisture to dry, an innovation that provides greater indoor comfort for years to come.
