Therm-All OptiLinerOptiLiner®: What Is It?

Designed for use in metal building walls and roofs, the OptiLiner® high-R system features an exceptional vapor retarder, an enhanced acoustical environment (both inside and outside of the building), and attractive finished appearance, with a bright interior finish which may allow for reduced lighting loads.

The high-R metal building insulation system uses a series of 1-inch galvanized steel straps to support a bright white or black polyethylene fabric that serves as the low permeance vapor retarder. The fabric sections are custom fit for each bay to ensure a swift installation and a clean interior finished appearance, which allows roof cavities to be completely filled with uncompressed insulation and maximizes thermal performance.

How OptiLiner® Helps Meet Codes

Therm-All OptiLinerOne of the difficulties in meeting code compliance for the building envelope is to prove the insulation system or application you are using meets the thermal performance (U-Value) listed for the specific code that applies to your project. This is not an issue with the OptiLiner® system since it meets the definition of Liner System (Ls) as described in the latest version of ASHRAE 90.1, which is also referenced by the IECC (International Energy Conservation Code).
