U factor u value range between 20 to 1 20. Call 888 330 3253 today. For most energy efficient windows the whole window u factor is higher than the center of glass u factor. That is quite low by today s standards and will ensure your hallway or kitchen benefits from keeping that all important and expensive heat inside.

A u value is a measure of heat energy moved through a given area of material in a given period of time. The lower the u value for a door the better. A higher u factor allows heat to escape. This calculated value conforms with bs en iso 10077 part 1.

This is desirable in very hot and sunny locations to avoid the greenhouse effect inside a home. Many such external elements will have to comply with thermal standards that are. High performance double pane windows can have u factors of 0 30 or lower while some triple pane windows can achieve u factors as low as 0 15. A u value thermal transmittance is a measure of how well an element of a building such as a window or door will transfer heat.

How is u value determined. Approximate u values are 0 8wm2k with a window energy rating wer pof a. U value is an inverse measure. Both of these terms r value and u value are commonplace terms in the remodeling and construction industry and are used to define how energy efficient a material is.

Our u value calculator is a whole window calculator designed to calculate an accurate u value of windows and doors. Let s begin with the r value and u value of windows.

Thus a single paned window with a basic aluminum frame has a u value above 1 usually around 1 25 while triple pane windows may have u values around 25 or lower.

Value windows doors inc. The lower the u value the better the thermal performance of the product. Is a leading supplier of high performance windows and doors that are elegant and energy efficient.
