Insulated Rolling Steel doors are made of two layers of steel with insulation in between they can be made out of different gauges ranging from 24 ga. to 16 ga. The lower the gauge the thicker the steel, if your door is wide (16’ or wider) you should consider a 22 or 20 ga. front with a 24 ga. back slat. Having a thick gauge helps with deflection of the door thus keeping the opening sealed at all times when the door is not in use.


As mentioned before an insulated garage door is made of two layers of steel with insulation in between each layer. These types of doors are much thicker than non-insulated doors. The insulation efficiency is measured with the R Value of the door, the higher the value the better the insulation on the product. Usually Rolling Doors have a value from 4.1. to 9.0. Most of our products also come with an environmentally friendly insulation that is made up of CFC-free and HCFC-free polystyrene, in addition they have a very low flame spread index tested by NFPA. Thermal efficiency Insulated Rolling doors can also help with Sound control, in fact, Rolling steel doors are also tested for Sound Transmission Class or STC. The Sound testing can range from 10 to 90 in average or higher, many Rolling doors are not ideal to cancel noise completely but most of them range into the high 20’s value of the STC measurement which can help reduce noise significantly.


A non-insulated garage door has an open back. Constructed only of steel, a non-insulated garage door is most appropriate for consistently warm or cold climates. If it gets too hot or too cold in a certain area, a non-insulated garage door will either seep cold air into the garage or overheat the garage.
