U Value Garage Door

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.

U value garage door.

R value measures the rate of heat loss but u value measures the rate of heat transfer. U factor represents the flow of heat through a material meaning the lower the u factor the better. Shoppers may get the impression that this number is important and it is but most are unsure about what it is or why they should even pay attention to it when choosing a garage door. 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. 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. 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. What is the standard r value for a garage door.

Clopay garage door r values depend on the door s thickness material and type of insulation and range from 6 3 to 20 4. A stylish and secure garage door not only enhances your curb appeal it can help keep you safe. 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 value is less commonly used by manufacturers.

However it s arguably the more accurate measurement of a garage door s thermal efficiency. It also has the important advantage of measuring the thermal efficiency of the door itself. U factor will vary between 0 66 and 1 00 depending on finish and color selection. Therefore the lower the u value the more energy efficient the material is.

See each collection or sell sheet for options. 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. U factor though not used as often as r value u factor is another number you may see when shopping for a garage door.

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. 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 the door s description may read 16 ft x 7 ft r value 6 5. The u factor is the measurement of thermal conduction due to heat flow through an installed door system.

If you have ever shopped for a new garage door you have probably come across an r value. The lower the number the lower the energy loss and therefore the better the thermal performance. U value is the inverse of r value.
