Metal Overhead Door U Factor

Overhead door corporation uses a calculated door curtain r value for our insulated doors.

Metal overhead door u factor.

For example a building with material with an r value of r 11 converts to an u value of 0 09 1 r or 1 11 0 09. Engineered for high thermal efficiency. L18 series honeycomb u factor 0 56 r value 1 80. B16 series steel stiffeners u factor 0 53 r value 1 89.

Thermal resistance is measured using r value and u factor. This door system presents the most advanced thermal performance values published by any major us manufacturer of insulated rolling steel doors with an r value of 10 9 u value of 0 09 and a tested installed u factor of 0 84. Thermacore series commercial sectional doors are an ideal choice for applications that demand the highest levels of thermal efficiency air infiltration and wind load resistance. B18 series steel stiffeners u factor 0 50 r value 2 01.

The lower the u value the better the insulating ability. Insulated sectional steel doors the insulated sectional steel door model 418 is a high quality heavy duty door that provides protection against hot and cold environments. Thermal resistance is a huge factor that affects the energy performance of insulated roll up garage doors when they are in the closed position. With an r value of 17 5 3 09 w m 2 a u value of 057 324 m 2 w and one of the best overall air infiltration ratings in the industry the thermacore model 592 is one of the most thermally efficient door system in its class.

We have several door styles to meet your insulated door needs for both residential and commercial applications. U value is the inverse of r value. All doors are tested in accordance with astm c1363 and sdi 113. Fabricated of 16 gauge flush galvanized steel exterior these 2 51 mm thick doors offer an r value of 7 35.

Overhead door corporation uses a calculated door section r value for our insulated doors. Reference table for u values u value is the coefficient of transmission i e the transmission of heat through the materials which compose the building s envelope or outer shell. The thermacore product line s unique manufacturing process provides a cfc free fully.

L18 series polystyrene u factor 0 38 r value 2 64. U value is a measure of the flow of heat through an insulating or building material. U value is a measure of the flow of heat through an insulating or building material. Thermacore is the premier line of insulated sectional doors available today.

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.
