Comparing the Various Insulation Materials

Choosing the right steel building insulation for your particular application and location can be tricky. Let’s take brief a look at some of the insulation options available.

To Insulate or Not to Insulate

First, determine if your new prefab steel building requires insulation. Refer to our recent blog Do You Need Metal Building Insulation?

STEEL BUILDING INSULATION OPTIONS

The initial cost and long-term effectiveness of the different steel building insulation materials varies.

Loose-fill: Loose fibers or pellets are blown into the wall cavities, using specialized equipment. Chemically treated shredded recycled newspapers, fiberglass, and rock wool offer three blown-in insulation choices. Blown-in insulation tends to be the more expensive choice, but seals well, especially in the corners. A separate radiant barrier is recommended.

Spray Foam: A polymer, combined with a foaming agent, sprays into steel wall and ceiling cavities. A liquid when released, the mixture expands quickly, drying into a solid mass of air-filled cells. While much more expensive than batt insulation, spray foam— when expertly applied— fills every tiny crevice, reducing air leaks.

Rigid Board: Fiberglass, polystyrene, or polyurethane formed into stiff boards creates another insulation choice. Easy to install, rigid board insulation trims easily to precisely fit the available space. Rigid board works particularly well on flat roofs, and is a superior soundproofing material. However, be aware that some local building authorities require additional flame-retardant facing for rigid-board insulation, such as half-inch gypsum board.

Batt: When correctly installed, processed rock wool or fiberglass batts provide the most bang for your insulation buck. Economical and effective, fiberglass batts remain the most popular choice for steel building insulation. (Batts are also known as “blanket” insulation.)

Vapor Barrier: Acting as a moisture retardant, a vapor barrier helps protect insulation. The less moisture permeates the vapor barrier material, the greater its protection. Required to be fire-retardant, a high-grade vapor barrier adds another layer of fire-resistance to a steel building.

The Pro-Value Insulation System

RHINO Steel Building Systems combines three of the best insulation choices into one highly effective insulating system.

Our “Pro-Value” package starts with economical fiberglass batt insulation. Insulation hangers keep the batt insulation firmly in place. Easy-to-install clip-on rigid board insulation creates a thermal break, increasing the overall R-value. Completing the package is a heavy-duty washable fabric vapor barrier, held in place with durable steel retaining straps.

We have found that 67% of our clients choose to include insulation with their steel building order. Most people using the Pro-Value Insulation Package report savings around 50% on their heating and cooling costs.
