Vinyl window r value.

The r value is the measure of heat flow resistance the higher the r value the better. While they are related different assumptions and test criteria are used in calculating the two values so they cannot be directly converted. The higher the r value the greater the insulation performance. When shopping for windows or doors look for higher r values and lower u values for the most energy efficient products possible.

The lower the u value the slower the rate of heat flow and the better the insulating quality. Ultimately when talking about windows the u and r values are both a representation of the same thing. Energy and the environment. R value measures how well certain building insulation materials can resist heat.

A window is considered to be low e if its emissivity is 0 35 to 0 05. A double pane window with a low e coating will have an r value equivalent to or better than a triple pane window. The more common term r value refers to the resistance of the window to heat conduction and it is the inverse of the u factor that is r value 1 u factor. Our windows and doors are engineered for energy efficiency.

Standard clear glass has an emissivity of about 0 84. The r value as it is known to most consumers is really an inverse representation of the u value. Better windows have high r values and low u factors see table 1. Alside vinyl windows have several replacement and new construction lines including double hung casement and bay windows.

How can a replacement window s u value be improved. While the u factor is used to express the insulation value of windows r value is used for insulation in most other parts of the building envelope walls floors roofs. If you like math a u value 1 r value the u value is the inverse of the r value. Fortunately window technology has greatly improved so it is now possible to have large expanses of windows.

A lower u factor means a better insulating window. And we test them to the extremes so you can count on them to last. U value is the amount of heat transferred through a material. The lower a unit s u value number the slower it transfers heat.

Alside windows are custom made to fit existing window openings. Since the different parts of a window all have different u factors. We ve designed the entire window including the frame and sash to perform at its best. Know exactly how much you need with our project calculators.

Optional foam insulation can further increase energy performance. The rate at which the glass transfers loses heat. R values of uninsulated concrete.

The higher the r value the greater the resistance.
