Insulated Overhead Door U Value

U value is a measure of the flow of heat through an insulating or building material.

Insulated overhead door u value.

Model 5720 12 76 r value. Thermal resistance is measured using r value and u factor. Even the best entry doors have relatively modest insulation levels. 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 fact that an exterior door is made of solid wood or steel with a layer of polyurethane does not mean that the door has a good insulation value. 0 56 to 1 13 w m2k which is high compared to other. 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. Engineered for high thermal efficiency.

The thermacore product line s unique manufacturing process provides a cfc free fully. Classic steel model 8500 has the highest level of garage door insulation for our residential doors with an r value of 16 22. The insulation of the best doors is in the range of u 0 10 0 20 metric. The imb v5 door s profile is also available with foamed in place polyurethane.

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. Alpine s imb v5 fast acting insulated overhead door rolling insulated door with insulated metal backed slats that are 5 8 inch thick slats with an r value. Model 5740 17 5 r value. Thermacore construction provides a continuous layer of foamed in place cfc free polyurethane garage door insulation sandwiched between two layers of corrosion resistant steel for maximum thermal efficiency.

Overhead door corporation uses a calculated door section r value for our insulated doors. Thermacore is the premier line of insulated sectional doors available today. We have several door styles to meet your insulated door needs for both residential and commercial applications. Fabricated of 16 gauge flush galvanized steel exterior these 2 51 mm thick doors offer an r value of 7 35.

Thermal resistance is a huge factor that affects the energy performance of insulated roll up garage doors when they are in the closed position. Garage door r value. 6 82 u factor of 0 147 calculated using the ashrae handbook of fundamentals the slats are insulated with polystyrene for increased thermal protection. 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.

U value has an inverse relationship to r value. 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. The effectiveness of the insulation is expressed as an r value which is a measure of thermal resistance to heat flow. The higher the r value the better the insulation in the door.
