Steel buildings have very unique insulation requirements versus more conventional styles of buildings. The styles and types of steel building insulation, door insulation, moisture control, and vinyl covered insulation should be  considered before beginning any steel building construction project.

Steel buildings are very distinct types of structures in many respects. Steel roofing and siding is impenetrable by water and air does not flow easily through the structure. Steel buildings are very good conductor. Insulation characteristics for steel buildings are inadequate as a base metal structure but moisture condensation is inherent in the type of material used (steel) along with the configuration of the building. Heated un-insulated steel buildings will lose most of their heat through the roof and sides of the structure during winter and moisture will condense throughout the interior.

There is now a standard for the proper insulation of steel buildings. The recommendations are for insulations with high tensile strength and post-compression thickness recovery.

White vinyl covered fiberglass insulation is specifically designed for steel buildings. The vinyl covering portrays a bright surface and is resistant to dust and condensation. The covering also acts as vapor barrier to help reduce condensation tendencies on the steel surface. Remember, insulation is only effective as a vapor barrier provided the seams are properly sealed. A new steel building should have the insulation installed before the roof and walls are attached to the structure. This is an easier process to follow than if the building is completed prior to insulation installation.

There are many factors that contribute to the propensity for condensation within a steel building. This will include, but not be limited to, the interior heat sourcing, the type of products under roof, the type of floor structure, and occupants of the building. Any water processes within the building will add to the likelihood for condensation. Dirt floors will cause moisture to evaporate. Vapor barriers need to be placed under any concrete pad to lessen condensation.

There are procedures that will help with moisture removal. The best way of eliminating the condensation process is by proper ventilation. The use of natural ventilation ( air space in the roof with a path to the roof vent) or mechanical ventilation (use of fan force) will help in significantly reducing the amount of moisture present within any steel building.

Doors can produce the greatest amount of heat loss within any steel building. Doors need to be insulated. Purchase pre-insulated doors from the factory or supplier. Fill existing un-insulated door panels with insulation. Sealing of the door is also critical and a gasket material needs to be attached to the panels and sides of the door to eliminate infiltration.
