Dominate Thermal Performance

Features And Benefits

Dual-Layer Protection

Combines OSB structural sheathing and Owens Corning® FOAMULAR® NGX XPS foam for dual layer protection.

Helps Achieve Energy

Installing LP NovaCore sheathing helps builders achieve LEED®, ENERGY STAR® and Green Building Standard ICC 700-2008 certifications.

High Performance in High and Low Temperatures

LP NovaCore Thermal Insulated Sheathing made with Owens Corning® FOAMULAR® NGX XPS foam provides continuous insulation without the long-term R-value deterioration associated with other foam insulation products.

Easy Installation

Panels can be cut and drilled the same as regular OSB and installed in a vertical or horizontal orientation, provided that all
panel edges are supported and fastened to wall framing or blocking. LP NovaCore is only to be used as wall sheathing and as specified in our installation instructions.

To create NovaCore Thermal Insulated Sheathing, a 7/16-inch OSB panel is combined with a 1-inch Owens Corning Foamular® NGX XPS Foam board designed for thermal efficiency. Owens Corning foam doesn’t absorb water, offering a long term R-value that stays reliable at R-5 per inch and increases with cooler temperatures without concern of degradation. XPS foam combined with OSB sheathing creates durable NovaCore panels designed for use as wall sheathing.

LP NovaCore FAQ

Neil Freidberg, Building Science Manager at LP shares the benefits of LP NovaCore Thermal Insulated Sheathing and answers to commonly asked questions regarding installation and more.


By using FOAMULAR® NGX XPS, the R-value of LP NovaCore sheathing increases as temperatures drop while
other polyiso foam products can see a decrease in their R-value as temperatures drop. With LP NovaCore
sheathing, builders in some climate zones can use 2x4 studs while still meeting strict energy codes. Plus – it
can be used to meet energy codes anywhere a climate zone allows an R-value of 13+5, or 20+5.
