Traditional roof insulation methods often fall short due to compression, thermal gaps, and inconsistent installation. Butler Roof Insulation systems solve these issues by using structured banded systems and high-performance liner systems that maintain insulation thickness and coverage across the entire roof.

By reducing thermal bridging and improving moisture control, these systems create a more efficient building envelope while maintaining long-term durability. The result is better performance, lower energy costs, and a roof system built to perform under demanding conditions.

The long-tab banded system involves using laminated insulation with extra-long facing tabs as well as metal banding for support. The extra-long facing tabs can be adhered to the tops of the purlins, suspending the insulation within the cavity , while the metal banding is attached using TEK screws perpendicular to and below the purlins to help support the weight of the laminated insulation in the purlin cavity.  

For roofs, faced fiberglass is installed parallel and between the purlins. Unfaced insulation is installed perpendicular and over the top of the purlins. The metal banding is secured perpendicular and to the bottom of the purlins. 

For walls, when a higher R-value is desired, unfaced fiberglass can be installed perpendicular to the girts and faced fiberglass parallel to the girts. 

The OptiLiner Banded Liner System is designed to provide maximum thermal performance of light density fiberglass insulation in metal building roof and wall applications.

The installed banding and fabric support system allows roof cavities to be completely filled with two layers of insulation with minimal insulation compression. When installed in strict compliance with the Bi-Directional Banding Roof Installation Instructions, OptiLiner® meets the requirements of OSHA Standard 29 CFR 1926.754(e) (3)(i) covers for roof and floor openings, and is used in both new construction and retro-fits.

Butler’s Insulation Systems utilizes high-quality vapor retarders as facings to protect our insulation from abuse and to manage moisture, keeping your building dry.

Our vapor retarder systems are engineered to control moisture movement within metal building assemblies, helping prevent condensation, protect insulation performance, and extend the life of the building envelope.

Designed for a wide range of environmental conditions, these facing systems provide controlled permeability to manage vapor transmission effectively without compromising thermal efficiency. Available in multiple performance levels, they allow for precise specification based on project requirements, building use, and climate exposure.

Each system is designed for compatibility with metal roof and wall insulation applications, ensuring consistent performance across commercial and industrial building environments.

Butler Cote colors are engineered for long term performance, with exceptional fade and chalk resistance that outlasts conventional paint systems. Cool Colors meet Title 24 energy standards and support LEED certification, giving your building proven longevity and a finish that protects your investment for decades.
