A high garage door u factor means that your garage door transfers heat easily.
U factor garage door.
U value is the inverse of r value.
Understanding r value rate of heat loss.
It tells you how effective a particular insulation material such as polyurethane or polystyrene foam is at preventing heat loss.
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.
The u factor is the measurement of thermal conduction due to heat flow through an installed door system.
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.
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.
The higher the r value the better the thermal efficiency of the material.
Of the two measurements the u factor will give a better representation of the insulating abilities of your fully installed garage door.
U factor represents the flow of heat through a material meaning the lower the u factor the better.
U factor will vary between 0 66 and 1 00 depending on finish and color selection.
Though not used as often as r value u factor is another number you may see when shopping for a garage door.
Your garage door u factor measures the heat transference of your garage door or how well heat can move through the material.
The lower the number the lower the energy loss and therefore the better the thermal performance.
Now that you understand why u factor is a better energy performance indicator lets discuss the details of it.
