This means that vinyl windows offer improved R-values, resistance to the transmission of heat, and offer higher energy efficiency than standard frame windows.
Vinyl window framing is scratch resistant, it comes in a wide variety of sizes and shapes, and the colorant is infused directly into the vinyl material. So, when window replacement is needed, think of vinyl windows because they are esthetically pleasing, cost effective, and will save money on energy costs. This means that the window frame will never need to be repainted. Not only that, but because vinyl window framing is custom made to fit, there is reduced air-leakage from gaps around the sills, framing, and the building's structure. Listed in their order of importance, the first factor is the glazing material, followed by the quantity of glazing layers, the size of the air-gap between the layers, the thermal resistance of the frame, and the quality of the seal between the window frame and the home. Of course, this film is optionally available in versions that allow full transmission of light. Moreover, these attractive windows are stronger than wood and aluminum, and are certified Energy Star compliant for all climate zones. Low emissivity (low-e) glass uses a specialized coating that can reflect up to 70% of aluminum alloy extrusion the transmitted heat while allowing the full spectrum of light to pass through. This type of glass has been coated with a specially designed reflective film that not only absorbs heat, but can also reduce the amount of light that is allowed to pass through.
Vinyl windows offer several options in the type of glazing that can be incorporated into the frame. . They are constructed using a double pane glazing configuration, and are filled with an inert gas to prevent transmission of heat. Lastly, there is a reflective glass option.
According to the American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE), five factors affect the R-value of windows.
Made from polyvinyl chloride (PVC), vinyl window frames do not conduct heat the way aluminum does, so they will prevent heat produced by sunlight from entering the home. This type of transmitted heat not only increases the temperature of the home, but can also deteriorate the home's drapes/curtains. Vinyl windows provide superior energy savings, and will make the aluminum display outside of the home look beautiful.A worthwhile construction project is one that includes installing vinyl windows. These windows are typically crafted using the LowE2 (Low Emissivity) glass standards providing a quality seal that keeps outside air from infiltrating the home, and inside air from leaving the home. There is also a heat absorbing glass option that can absorb up to 45% of incoming radiant heat generated by the sun's rays.
Vinyl window frames include a heat mirror to prevent IR (infrared radiation) from entering and heating the home's interior.
