U Value Garage Door

If you have ever shopped for a new garage door you have probably come across an r value.

U value garage door.

For best u factor choose finish and color with high solar reflectance bright colors. It also has the important advantage of measuring the thermal efficiency of the door itself. R value is the thermal resistance to heat flow which generally applies to specific materials or the thickness of the insulation in a garage door section. U factor though not used as often as r value u factor is another number you may see when shopping for a garage door.

U factor represents the flow of heat through a material meaning the lower the u factor the better. See each collection or sell sheet for options. What is the standard r value for a garage door. The u factor is the measurement of thermal conduction due to heat flow through an installed door system.

But ultimately the lower the u value the less you are going to pay in energy bills if the garage is attached to your home. 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. 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 is the inverse of r value.

When you want to give your home that boost in value with a garage door installation we make it fun and easy to complete the project make the smart investment on a new residential garage door available right away or designed just how you like it to get the perfect style for your home. With a quality double glazed unit approximate u values are 1 2wm2k or alternatively a window energy rating wer of a. Here are the answers to some of the most. Installed u factor a tested value of actual energy loss whether heat or cold of an installed door wall or window assembly.

Do bear in mind that u values are really only a guide and there are other factors as we have mentioned previously that will affect that the final insulating values that a particular door installation will provide. R value measures the rate of heat loss but u value measures the rate of heat transfer. For example the door s description may read 16 ft x 7 ft r value 6 5. The u value of a garage door is a measure of the amount of heat that passes through a surface area of 1m2 for each degree of temperature difference between the inside and outside.

U factor will vary between 0 66 and 1 00 depending on finish and color selection. The liniar energyplus range contains 6 chambers and can achieve a u value as low as 0 8 w m2k with the correct glazing specification. A stylish and secure garage door not only enhances your curb appeal it can help keep you safe. Clopay garage door r values depend on the door s thickness material and type of insulation and range from 6 3 to 20 4.

U value has an inverse relationship to r value. U value is less commonly used by manufacturers. However it s arguably the more accurate measurement of a garage door s thermal efficiency.
