What is R-Value?
An R-value is a rating which measures how well insulation can resist heat flow. ‘R’ stands for thermal resistance. The R-value depends on the type of material, its density and thickness. The higher the R-value, the better the insulation is at reducing heat flow. This means, for example, that R2.6 insulation is more effective than R1.6 insulation.

With a high R value of 4.8, the Ulti Insulated Sectional Door provides your doorways with excellent thermal control, reducing heat transfer in hot and cold weather.
Weather tight seals around the perimeter of the door mean these doors are great for external applications, especially for a dock door, to reduce energy losses around the perimeter of the door. See also our Banana Room Doors and Controlled Atmosphere Doors for other fully sealed door options.
With an STC rating of 25.1 it provides a substantial acoustic barrier for your facility, blocking off any unwanted noise from either inside or outside.
