U Factor Chart

U Factor Chart - The lower the shgc number, the greater the blockage will be. This stands for british thermal units per hour, representing the amount of heat energy. The shgc measures how much of the sun’s heat comes through the window. Table 6.a.1 applies to windows (and rooflights) with wood or plastic frames. Are independently tested, certified, and verified by the national fenestration rating council (nfrc), and have nfrc ratings that meet strict energy efficiency guidelines set by the us environmental protection agency (epa).; Upper values are for doors with no thermal break. Code regulations are consolidated by state and city for easier navigation. A number which describes, in specific terms, the ability of a material or assembly to transmit heat from outside to inside surfaces. Lower values are for thermally broken doors; The lower the number, the more energy efficient the product is.

Three components are used to. Code regulations are consolidated by state and city for easier navigation. Table 6.a.2 applies to windows with metal frames, for which the adjustments (for thermal breaks and/or rooflights) in table 6.a.3 should be applied. The shgc measures how much of the sun’s heat comes through the window.

Upper Values Are For Doors With No Thermal Break.

Lower values are for thermally broken doors; The lower the number, the more energy efficient the product is. This denotes square footage, indicating the area over which the heat flow is being measured. Values are for thermally broken or thermally unbroken doors.

This Stands For British Thermal Units Per Hour, Representing The Amount Of Heat Energy.

The lower the shgc, the less solar heat the window lets in. A number which describes, in specific terms, the ability of a material or assembly to transmit heat from outside to inside surfaces. Shgc (solar heat gain coefficient) indicates a window or door’s ability to block heat generated by sunlight. The lower the number, the better a product is at keeping heat in.
