Code Officials
SIMPLY SMARTER BUILDING MATERIALS THAT CODE OFFICIALS EMBRACE.
Far too long risk aversion has defined the construction industry. It’s why the industry has been slow to adopt new technologies, methods, and materials – even when they would provide significant performance and economic benefit – even when backed by rigorous science and testing.
Fortunately, this mindset is changing. Today, new technology, methods, and materials are being adopted and approved by code officials, which, in turn, is elevating construction quality and performance, while decreasing cost.
OX remains proudly at the forefront of this movement.
Here are some OX innovations that, for the better, are replacing traditional materials and methods.
ThermoPLY®Structural Sheathing
At just fraction of the thickness and weight of OSB, OX ThermoPLY structural sheathing provides the structural
equivalency of OSB and eliminates the need for building wrap when installed with OX seam tape to provide a
best-in-class water and air barrier. Apart from speed of installation and reduced labor costs, home builders
especially appreciate the stable pricing of ThermoPLY compared to the continually fluctuating cost of OSB.

The benefits of Thermo-Ply vs. OSB |
|
| Thermo-Ply Structural Sheathing by OX | OSB (Oriented Strand Board) |
| No added asphalts, formaldehide,phenols or CFCs | Made from wood chips, may contain formaldehyde. Formaldehyde is a probable human carcinogen. |
| Stable pricing | Commodity, rapid price fluctations |
| Extrusion Coated WRB on both sides | Requires additional WRB layer |
| High moisture tolerance | Low moisture tolerance. Significant swelling when wet, which could produce mold. |
| Tight seal controls air infiltration for lower ACH | Average air infiltrations perfomance |
| Custom sizes and private labeling avaliable | Typically no custom sizes or print available |
| 13 lbs for 4’x8’ sheet (RED) | 45 lbs for 7/16’’ x 4’8’ sheet |

OX-IS®Structural Insulated Sheathing
A major advancement in building science, OX-IS structural insulated sheathing is durable sheathing, continuous
insulation, a superior air barrier, and an effective water-resistive barrier in one easy-to-install component. OX-IS
has been exhaustively tested by a 3rd party lab, meeting or exceeding the most stringent building codes for
structural sheer values, comparable to a 7/16” sheet of OSB.
| Physical Properties of OX-IS ( foam properties) Complies with ASTM C1289, Type 1,Class 1 |

Strong-R® Structural Insulated Sheathing
Engineered to meet or exceed commercial construction code requirements, Strong-R structural insulated sheathing
combines a strong and resilient sheathing, continuous insulation, a superior air barrier, and an effective
water-resistive barrier into a single easy-to-install component. Strong-R has been exhaustively tested by a
3rd party testing lab, proving compliance with ASTM E84, ASTM E119 and NFPA 285 assemblies.
