U Value Garage Door

For example the door s description may read 16 ft x 7 ft r value 6 5.

U value garage door.

U value is the inverse of r value. 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. R value measures the rate of heat loss but u value measures the rate of heat transfer. It also has the important advantage of measuring the thermal efficiency of the door itself.

A stylish and secure garage door not only enhances your curb appeal it can help keep you safe. Therefore the lower the u value the more energy efficient the material is. See each collection or sell sheet for options. However it s arguably the more accurate measurement of a garage door s thermal efficiency.

U value is less commonly used by manufacturers. With a quality double glazed unit approximate u values are 1 2wm2k or alternatively a window energy rating wer of a. For best u factor choose finish and color with high solar reflectance bright colors. What is the standard r value for a garage door.

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. 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. 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.

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.

Installed u factor a tested value of actual energy loss whether heat or cold of an installed door wall or window assembly. 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. Clopay garage door r values depend on the door s thickness material and type of insulation and range from 6 3 to 20 4.

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. Here are the answers to some of the most. U factor represents the flow of heat through a material meaning the lower the u factor the better.
