Today, continuous
insulation
(CI) is a must.

The ultimate solution
is OX.

Meeting increasingly more stringent energy codes requires the use of CI (continuous insulation located outboard of framing members). With OX’s powerful structural insulated sheathing systems, you achieve robust CI and a superior air and water barrier - all with just a single product.

OX Structural Insulated Sheathing
products provide 4 functions in 1:

STRENGTH

Comparable shear values to 7/16" sheet of OSB

THERMAL BARRIER

Best in class R-Value per inch

AIR BARRIER

Built in air barrier eliminates the need for residential or commercial wrap

WATER BARRIER

Code-approved WRB integrated onto facer

ox

the epitome of power and efficiency

You build faster, stronger, smarter, and reduce risk with OX. That’s because advances in building and material sciences render multi-component exterior backup walls obsolete and highly inefficient – in time, labor, logistics, and energy.

Single-component OX Structural Insulated Sheathing products provide ultimate efficiency:

FASTER TO
INSTALL

Eliminates separate WRB/AB and CI steps

LESS
LABOR

Requires only one trip around the structure to install

SIMPLIFIED LOGISTICS/
REDUCED RISK

Single product. Single supplier.
Single installer. Single Warranty.

SUPERIOR THERMAL
PERFORMANCE

Eliminates thermal bridging through studs

Sheathing

Fasteners for cladding penetrate through water barrier creating a pathway for water to damage sheathing over time.

2x4 Construction
with OX-IS®

To comply with more stringent energy codes you can increase framing to 2"x6" to accommodate thicker insulation. But the far better solution is to incorporate continuous insulation with OX-IS.

Does it really work?

Thermal imaging of the same structure with and without continuous insulation shows the incredible effect it can have on your structure’s thermal performance and energy efficiency.

BUILT WITHOUT INSULATED SHEATHING

Without continuous insulation, heat loss through framing (thermal bridging) is significant.

vs.

BUILT WITH ½” (R-3) CONTINUOUS INSULATION

Even just ½” of continuous insulation greatly reduces heat loss through wall framing and improves on cavity performance.
