L18 Series (Honeycomb) U-Factor = 0.56 R-Value = 1.80. These doors are often specified at high abuse areas or can be used at openings where sound transmission ratings are a concern. [B18 Series, per ASTM C1363] R-Factor = 2.01 / U-Factor = .50. 5. Mineral Core. Hollow metal doors can be specified ProVia is committed to helping you find energy-efficient doors and windows that meet ENERGY STAR requirements.

Doors lose heat to the outside in the Winter and gain heat from the outside during the Summer; 1" insulated glass can reduce the U-factor by up to 40%* by better preventing interior heat from escaping to the outside; Depends on size, temperature and components of the door; REFERENCE NUMBERS. Colder climates want a low UFactor (.52) to resist U-Factor is the measurement of how well a building material—typically windows and doors—keeps heat inside of a building or home. The lower the U-Factor, the greater the door's resistance to heat flow and the better its insulating factor. 2020-02-07 R-value to U-value Conversion Calculator provides R & U values.

Thermal resistance is a huge factor that affects the energy performance of insulated roll up garage doors when they are in the closed position. Thermal resistance is measured using R-Value and U-Factor.

U-Factor - The total or overall transmission of heat through a combination of materials assembly measured in BTU’s per hour per square foot of area for a difference in temperature of 1 ˚F between the air on one side to the air on the other side. THE LOWER THE “U” VALUE, U-Factor: The heat transfer per time per area and per degree of temperature difference in W/m 2 ∙K (Btu/h ft 2 ∙˚F). The U-factor multiplied by the interior-exterior temperature difference and by the projected fenestration product area yields the total heat transfer through the fenestration product due to conduction, convection, and long-wave infra-red radiation. Thermal resistance is a huge factor that affects the energy performance of insulated roll up garage doors when they are in the closed position. Thermal resistance is measured using R-Value and U-Factor. Air Leakage on the other hand refers to the seal at the overhead door guides, head and hood while the rolling door is in the closed position.

The fenestration product and exterior door's U-factor shall be rated in accordance with NFRC 100, or use the applicable default U-factor set forth in Table TEC14902. ENERGY PERFORMANCE RATINGS. U-Factor (Btu/hr-ft2-oF) / Solar Heat Gain Coefficient (SHGC). PRODUCT DESCRIPTION. DEFAULT FRAME.

Window values represent non-tempered glass. Use of tempered glass can increase U-Factor ratings. See andersenwindows.com/nfrc for specific … Associated Materials, Inc. 6400-6500 Series - 3" All. ASO-A-70. 0.16-0.20. 0.07-0.31.

Harvey Windows and Doors. 12 Dec 2018 The U-value is not rating a material. Rather, it's the calculation of the conduction properties of various materials used to build windows, doors, 3 Jul 2019 The maximum U-factor for doors with less than 25% glazing will be 0.20. Skylight requirements remain unchanged.
