R–VALUE vs. U–FACTOR

Company:               DL Manufacturing

Sector:                   Loading Dock Doors

Problem:                 HIGH ENERGY COSTS – Too often decisions for purchasing Loading                               Dock Doors are based only on the R–Value of the Door. To reduce                               energy costs in real world applications, consider the U–Factor.

Solution:                  MxV Knockout Dock Doors offer not only great R–Value but more                                importantly superior U–Factor by using brush technology. 

Simply stated, R–Value is a measure of heat flow resistance and U–Factor is the measure of heat transfer.  The R–Value is used to rate the energy efficiency of a single component on a door, such as a door panel.  The U–Factor takes a more scientific approach, it looks at the entire dock opening, from jamb to jamb, floor to ceiling, cracks, etc. 

The bottom line is that U–Factor rates how much heat is conducted through this combination of materials.  So, where R–values rate how much heat loss the material resists from passing through it, U-values rate how much heat the component parts allow to pass through the dock opening.    

The MxV addresses both issues.  First the door panels are rated at R–16 but more importantly our full perimeter brush seal mounts to the door and not the door jamb. This eliminates the need for costly jamb seals that are mounted in harms way and are a maintenance nightmare.   MxV virtually eliminates all air and light gaps.  Furthermore, the seals remain intact through constant loading dock abuse.  Other doors can offer great R–Value, howeve,, the U–Factor takes over and eliminates any benefit gained by the high R–Value once the door is hit with a forklift truck.
