U Factor Garage Door

R value is the most common measurement for insulation in garage doors.

U factor garage door.

It tells you how effective a particular insulation material such as polyurethane or polystyrene foam is at preventing heat loss. U factor and air infiltration results for clopay commercial sectional doors. Understanding r value rate of heat loss. Of the two measurements the u factor will give a better representation of the insulating abilities of your fully installed garage door.

Building codes standards such as those found in leed iecc and ansi ashrae ies standard 90 1 provide guidelines and standards for how sectional overhead doors should be made and how they. U factor represents the flow of heat through a material meaning the lower the u factor the better. Your garage door u factor measures the heat transference of your garage door or how well heat can move through the material. The thermal performance and energy efficiency of commercial sectional overhead garage doors has become an increasingly more important factor to consider when designing building and maintaining commercial or industrial spaces.

Now that you understand why u factor is a better energy performance indicator lets discuss the details of it. The higher the r value the better the thermal efficiency of the material. U factor measures the rate of heat transfer and is appropriately applied to the thermal efficiency of windows which similar to insulated roll up garage doors are assemblies comprised of multiple components. The lower the number the lower the energy loss and therefore the better the thermal performance.

To keep your garage cool in summer or warm in winter you want a garage door with a u factor of 35 or less although the lower the u factor the better. U factor will vary between 0 66 and 1 00 depending on finish and color selection. Installed u factor a tested value of actual energy loss whether heat or cold of an installed door wall or window assembly. U value is the inverse of r value.
