Sometimes, to understand a product, it is important to know what goes in a product. Many of C.H.I.’s garage doors are built with insulation, either polyurethane or polystyrene. To indicate the effectiveness of the insulated garage door, each door is rated with an R-value. The higher the R-value, the better the insulation properties and the greater the resistance is to heat flow.
To find out more about door insulation and R-values contact a certified C.H.I. Distributor.
