If you are planning to insulate your steel building, you might already know the basics, like keeping the warm air in during winter and the cool air in during summer. But when it comes to choosing the right insulation system, things can get a bit more complex. While the basics are discussed in the blog An Overview of Metal Building Insulation, let’s break down some of the more advanced insulation options and requirements you might encounter when insulating your steel building.
Choosing the Right Insulation System
Blanket insulation is one of the most popular choices for steel buildings—and for good reason. It’s cost-effective, easy to install, and works well for most standard applications. But if you’re looking for something more efficient, the Energy-Saver System could be the game-changer you need.
Single Blanket Insulation: A Reliable Standard
One of the most common and cost-effective insulation methods, Single Blanket Insulation uses flexible rolls of fiberglass which is simply rolled on top of the structural members, covered with the roof or wall cladding, and screwed into place. It is easy to install and suitable for a wide range of applications.
Key Features:
- Thermal Efficiency
Helps maintain comfortable interior temperatures and reduces heating/ cooling costs - Moisture Control
With vapor barriers, it reduces condensation buildup, preventing interior water damage - Acoustic Performance
Diminishes sound reverberation and transmission, reducing noise levels
Blanket insulation comes in R-values as low as R8 which can be used to prevent condensation in buildings that are not going to be heated. A typical insulation package for our EasyBuild Model is an R13, 4” blanket insulation on the Walls of the building and an R20, 6” insulation on the Roof. Single Blanket insulation is an ideal solution for low frequency buildings used for garages, storage, and light work areas.
Energy-Saver Systems: A High-Performance Upgrade
The Energy-Saver System combines blanket insulation with a Cavity Fill layer that increases the R Value on any building, including the EasyBuild. This system allows us to boost energy efficiency and achieve R Values up to R60 for Roof and R50 for Walls. In such cases, additional insulation is
installed in between the girts and purlins, thereby “filling the cavity” and increasing the overall R-Value. In some cases, the girts and purlins of the building are made deeper, so that there is a larger cavity to accommodate the higher R-Values.
Key Advantages:
- Optimized R-Values
Achieves higher thermal resistance for code compliance - Air Tightness
Reduces air leakage for improved energy efficiency - Durability
Resistant to wear, mold, and mildew - Aesthetic Appeal
Provides a clean, finished look for exposed ceilings
Why does this matter for you?
Better insulation means lower energy bills and a more comfortable space, whether you are working, living, or storing valuable equipment inside your building. It’s a simple upgrade that pays off in the long run.
Wondering how to install it? By now you realize that fiberglass insulation is most effectively and easily installed while the building is being assembled. Don’t worry, we have got detailed installation manuals to guide you every step of the way. Each insulation roll will be individually wrapped in a thick plastic bag which will be clearly labelled, and color coded.
Meeting SB-10 Requirements
When you are planning your new Metal Building System, or even if you intend to add an extension to your existing structure, you need to ensure that you are in compliance with the SB-10 energy efficiency codes. SB-10 is the section of the Building Code that dictates the energy efficiency requirements for buildings and includes performance requirements for heating, cooling, ventilation, hot water systems, and even lighting. SB-10 requirements are essential for getting your building permits approved, and they vary depending on your building’s size, application, and location. In some cases, meeting these standards might require design changes, like switching to a Standing Seam Roof to allow for higher R-values.
SB-10 matters because it ensures your building is energy-efficient and compliant with local laws. Investing in an insulation package that meets these standards will save you headaches down the road—think lower energy costs and fewer retrofits. Our team at Norsteel can help you navigate these requirements and make sure your building is up to code.
Fire Safety with Rockwool Insulation
When fire safety is a priority, Rockwool, (aka Mineral wool) insulation is your go-to solution. This mineral-based insulation provides excellent fire resistance, offering ratings of one or even two hours, depending on the application. For steel buildings, this is a reliable way to meet fire safety codes while maintaining the structural integrity of your space. The design of the metal building system changes to accommodate the fire rated wall.
Following W605 requirements, in the case of one-hour fire-rated walls, we add girt lines at 4’ centers, a sealed 24-gauge liner and two 4” layers of Rockwool in the cavity.
Achieving a two-hour fire-rating is similar. Following W606 specifications, the building is designed with girt lines at 4’ and both the interior liner as well as the exterior cladding must be 24-gauge steel. The liners are sealed and again, the cavity is filled with two layers of 4” rockwool insulation.
What does this mean for you? Peace of mind. Whether you are insulating a warehouse, an office, or a backyard barn dominium, Rockwool helps protect your investment and ensures safety for occupants.
