Insulation
Built for Function. Designed for Finish.
Enhance energy efficiency and comfort with Northern State Steel’s premium metal building insulation. Designed for durability, moisture control, and long-term performance – built to fit your project with precision
Energy Saver
Energy Saver (OSHA-compliant leading edge fall protection) roof system fabric is installed under the roof secondary structure and is supported by a banding grid system. Unfaced glass mineral wool insulation is installed between and above the purlins in varying thickness combinations to obtain the desired insulating values.
R Value 29-43
Full Cavity
No visible purlins

Specs
- Our premier system can meet or exceed IECC 2015 energy code requirements
- Provides a clean and finished appearance of roofs and walls by hiding the purlins and girts
- Improves acoustical performance compared to no insulation
- When installed to manufacture’s specifications provides a barrier to air leakage and contributes to a better airtight building.
- Manufacture’s fabric welding technology creates a continuous single custom sized fabric.
Sag-N-Bag
Sag-N-Bag is a double layer insulation system consisting of faced blanket insulation and unfaced insulation.
R 7-32
Over Framing
Exposed Purlins

Specs
- Over the purlin insulation system, economical alternative for increasing R-values
- Custom designed faced blanket to fit your specific project dimensions
- Unique hot melt lamination technology virtually eliminates wrinkles
Faced MBI Roof
Faced MBI is a single layer faced blanket insulation. Our manufacture provides a variety of facing options. Whether the goal is code compliance, aesthetics, or a vapor retarder, we partner with facing manufactures to provide the perfect facing for your project. Our manufacturer unique welding process creates custom fabric pieces to minimize seams and maximize strength.
