U Value Of Windows And Doors

The lower the u factor the better insulated the window. 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. Improved education and awareness of the cost of heating and cooling that escapes from poorly insulated components and glass panes have led to window and door manufacturers developing energy efficient windows and doors typically labeled r5 u 2 meaning the glass is the most energy efficient possible at a 5 rating and the window or door with all of it s built out components are a 2 which is almost as low as any rating can go remember a 5 is the highest energy rating for r value which is.

U value of windows and doors.

U factor u value range between 20 to 1 20. Our u value calculator is a whole window calculator designed to calculate an accurate u value of windows and doors. We can advise on how you might achieve the required standard. This might be a window but it might equally be a wall or a door.

This calculated value conforms with bs en iso 10077 part 1. It s most often measured in watts per metres squared when the difference in temperature between the two sides is one degree kelvin. With a quality double glazed unit approximate u values are 1 2wm2k or alternatively a window energy rating wer of a. 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.

For most energy efficient windows the whole window u factor is higher than the center of glass u factor. The u value or u factor measures how much heat a window including the frame glass and insulating materials allows out of the house which is also known as its thermal transmittance. U value is an inverse measure. The lower the u value the better the thermal performance of the product.

A u value is a measure of heat energy moved through a given area of material in a given period of time. Call 888 330 3253 today. A higher u factor allows heat to escape. A u value calculated by us should be sufficient to satisfy the requirements of building regulations.

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. 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. How is u value determined. The only exception to this rule are roof and skylight windows with low e smartsun glass which offer a u factor of 0 35.

The lower the u factor the better the window is at keeping heat inside this is desirable in colder climates like the northeast. Low e smartsun windows and doors feature the best heat insulation of all andersen products with u factors ranging from 0 24 to 0 25. Is a leading supplier of high performance windows and doors that are elegant and energy efficient. What are u values and energy ratings for windows and doors.
