2 U.S. ENERGY STAR Criteria for Doors The U.S. standards include criteria for air leakage. Swinging doors cannot exceed 0.5 cfm/ft. Glazing Level Opaque < or = 0.17 No criteria < or = 1/2 Doorlight < or = 0.25 < or = 0.25 > or = 1/2 Doorlight < or = 0.30 < or 0.40 for Northern and North-Central Zones...< or = 0.25 for Southern and South-Central Zones Climate Zone Map Northern North-Central South-Central Southern

3 Energy Efficiency Ratings in Steel Doors Half Light 36 & 3/4 Oval CL /4 Light 48 & Large Oval Full Light 64 & Meets Energy Star Criteria All Zones North & North-Central Zones : Defines the amount of heat loss. The lower the value, the less heat is transmitted through the entry door. Solar Heat Gain Coefficient (): The portion of directly transmitted and absorbed solar energy that enters the interior. The lower the value, the less heat is transmitted through the entry. Daylight Transmission/Visible Transmission (): Measures how much light comes through the entry. The higher the value, from 0 to 1, the more daylight is let in over the unit area of the entry. The performance ratings above were developed by Architectural Testing using applicable NFRC procedures for determining whole product performance. The ratings are determined for a fixed set of conditions and specs. When installed in the proper door, select RSL doorglass products meet regional ENERGY STAR thermal performance standards as defined by the U.S. Department of Energy (DOE) and Natural Resources-Canada (NR-Can). Energy efficiency ratings for RSL doorglass products vary by door construction, and the size and materials of doorglass assembly.

5 Sound Transmission Class (STC) Ratings In Steel and Fiberglass Doors Sound Transmission Class (STC) Ratings CL- - Full Lite 22 x 64 Full Lite 22 x Sound Transmission (STC): Measures how much sound comes through the entry. The higher the value, the more sound transmission is reduced. The performance ratings above were developed by Architectural Testing using applicable NFRC procedures for determining whole product performance. The ratings are determined for a fixed set of conditions and specs.
