Developments in technology and in window design and management techniques have led to the manufacture of extremely weather-tight wood windows with low U-values and hioh R-values.

Pinpointing Energy Lors

Energy loss from windows occurs primarily at three points: conduction of heat through the glass pane, leakage of cold or warm air into or out of a house through the frame and sash and leakage around the frame

Preventing air leakage around the frame depends on how well the rough opening is construcled and weatherized and how well the window unit f its in the openingfactors independent of the quality of a manufacturer's window unit.

Wood: A natural Insulator

Wood window manufacturers have redesigned frames and sash to help cut air infiltration through window units.

A cut-away of a replacement wood window show the features engineered into todays syslerns. New features built into replacement windows also include spring-loaded balances, tubular and leaf weatherstripping, flexible jamb liners and vinyl glazing, and c om pression weatherst ri pping. Many of these engineering improvements focus in on promoting energy conservation around window areas.

Wood is a better insulator than aluminum used in many aluminum replacement windows. ln fact, aluminum conducts heat '1 ,770 times faster than wood, according to the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE), Atlanta, GA. Aluminum windows can mean a colder home.

Condensation forming on window interiors also, is a oroblem inherent in metal replacement windows, but less so in wood windows. Even with a thermal break built into units, aluminum windows do not match the insulating qualities and low condensation f actors of wood windows, says ASHRAE.

I ndeed, the state of the art of replacement wood window system is a muchchanged picture from 10, five, even rwo years ago.
