Impact-rated IG's will have a pane of glass that is approximately 0.340" in addition to a standard pane of 0.125".
U-FactorDescribes the resistance of the door glass to conducting heat and cold through the unit. Lower values have greater insulating qualities.
SHGCThe Solar Heat Gain Coefficient describes the ability of the door glass to block heat caused by sunlight from heating a building's interior:
*A special note about customer-specific jargon shown in the MPC column: Door manufacturers are allowed to write anything they wish in the MPC column and frequently use jargon specific to only that manufacturer.
