Metal building insulation systems can be simple using fiberglass insulation glued to vinyl coating. The insulation system drapes over the structural purlins and girts. Insulation fits between these members and the exterior metal panels. The vinyl facing is to the inside showing a tight white vinyl between the support members. 
Filling the purlin or girt cavity adds extra R Value, and banding systems hold the additional fiberglass in place. Vinyl can be draped over the steel members to hide them also. R values on buildings range from R4 to R38 and above. Insulation systems can be designed to meet your local energy codes, such as the IECC 06, 09 or 2012. Let’s discuss the best type for your your application.
