R5 triple pane windows & patio doors

 

R5 insulation rating=U-vlaue .20

 

 

R5 is Eco-Friendly Energy Efficiency

 

Common Energy Star windows and patio doors only have an R rating of 3.  This series has a R rating of 5 for the ultimate in energy efficiency.

 

How Much Difference Does an Energy Efficient Window Make?

 

Heat and cold transfer throught windows causes approximately 30% of heating and cooling energy costs nationally.  That is an annual of 4.31 quadrillion BTU of energy consumption.

 

R5 = U-Value .20

 

U-value is the rate of heat flow through a window; the lower the value, the better the insulating quality.  Most commonly the U-value is used to measure a window's total insulating value.  R-value is the resistance of a material to heat flow; the higher this number, the better the insulating value.

 

Benefits

 

• Reduced heat loss in the winter, better than typical Energy Star or Low-E windows

• Potential for significant reduction in energy costs

• Moderate to significant reduction in noise levels compared to double pane windows

 

Features

 

• Triple-Glazed:  the insulated glass unit on a R5 window has three panes of glass

• Krypton Gas filled between the panes (Krypton has significantly better insulating qualities than Argon)

• Double Low-E glass:  Low-E is on the exterior pane and the interior pane
