There are many different insulation options available for a steel structure. A few options include Batt and Blanket, Spray Foam Insulation, and Bubble Insulation. Insulation effectiveness is measured by its R-Value. The R-Value indicates the insulations ability to resist heat from entering or leaving the area. The higher the R-Value, the higher the insulation’s performance levels.
Batt and Blanket insulation is processed from mineral fiber typically of fiberglass or rock wool and may include a radiant barrier blocking (the best for metal buildings). R- Value – R-3 – R-30 depending on thickness (approximately).
Spray Foam insulation is a great option because of how well it seals the building from insects and pests A polymer, combined with a foaming agent, sprays into the steel wall and ceiling cavities. The liquid turns into a solid cellular material of air-filled cells which fills every space – even the small spaces where air will not escape. For areas prone to cold weather. R- Value – Open-cell Spray Foam R-3.7 per Inch (approximately) and Closed-cell Spray Foam R-6.5 per inch (approximately). Wisconsin Carports DOES NOT provide spray foam insulation.
Bubble insulation is composed of polyethylene bubbles that function as additional thermal barrier and stops condensation. Since steel conducts heat well, a metal building naturally transfers heat energy in and out very freely. Bubble insulation resolves this problem by reflecting radiant heat to keep the temperature differential off your buildings steel panels. If your bubble insulation has a perm rating of less than 1.0, it will be classified as a full vapor barrier. A vapor barrier prevents moisture from passing through our insulation and getting to the steel panels where it can turn into condensation. R- Value – R-6 – R-10 (approximately). Wisconsin Carports DOES provide bubble insulation.
