Steel Building Insulation Options
Benefits & Drawbacks for Each Type of Insulation
Condensation is a major concern in metal and steel buildings, as rusting from a result is a common occurrence. Insulation serves to protect a structure from condensation and the side effects that stem from it, creating a vapor barrier to reduce how much condensation takes place directly on the panels. A concrete foundation that isn’t fully cured can be a contributing factor to increased humidity, which is another issue with steel buildings. Diligent installation is more impactful in stopping air infiltration than the type of insulation itself.
Choosing the right insulation for a metal building kit helps to reduce energy consumption and in some states, allow those constructing the building to claim tax incentives for making the effort to save energy. Steel panels alone offer no protection from the outside temperature, meaning there is no natural barrier to heat and cold. Adding the right type of insulation helps to control the conduction of outside temperatures. The result will be a building that stays cooler in warmer months and warmer once the temperature drops.
6 Other Benefits of Good Insulation
The part of the insulation that faces the inside of the building is known as the facing. Facing material must be carefully selected if it is going to be left exposed. In this case, the facing doubles as the inner wall material, and needs to be a type which is reinforced with a layer of scrim (fiberglass or nylon mesh). This will increase its durability, protecting it from punctures and scratches. Because of its more vulnerable location, the durability of wall facing is more important than that of the roof facing. “Bird proof” varieties are available for agricultural buildings.
It’s worth noting that the color of exposed facing will contribute to the light inside. With white or reflective foil facing, fewer sources are required to light up the interior. Blackfacing may be preferred for a darker ambiance.
Both partial and full-height are available from some manufacturers, which protect the insulation and contribute to the inner appearance of their buildings. General contractors can also be hired to add walls. When the insulation is covered and protected, the durability of the facing can be increased.
To minimize the transfer of condensation, insulation facing with a low perm-rating must be chosen. With a perm-rating of 1.0, plain vinyl is not considered protection against condensation. Facing with a perm-rating less than one-tenth (0.1) will provide sufficient protection against condensation for most applications.
Certain types of insulation cannot be shipped or installed in cold weather during winter. It is a good idea to ask the manufacturer about the material’s workability if a project is taking place in a cold climate.
