Window Replacement – R Value and U Values

June 22nd, 2012

As most of us are familiar with the term window replacement but have rarely heard about the terms like R-Value and U-Value. These terms are associated with windows. Read through this blog to know more about it.

The R-Value is a measurement of insulating ability demonstrated by a window and its ability to prevent heat loss. The windows with high R-values lower the loss of heat and also lower the heating costs in chilling winters. This value is usually measured towards the center of the glass and most of the modern day glass windows are sealed within to prevent the loss of heat. This value is used for measuring the conductivity.

The U-Value is a measurement of ability of heat conductance. Their values usually range from 0 to 1.1 and should bear lower U-values. U factor is used to measure more than conductance. This term is often used in connection with emissivity of the glass. The emissivity is ability of the product to absorb some energy and radiate through room.

This means these are the two important factors which you should consider prior to buying any glass window doors for installation in bathroom, kitchen or any other rooms within the home.
