Double glazed windows are the most popular windows out there today – and for good reason! You see, a double glazed window is a window with two panes. This not only makes it more durable, but provides increased insulation as well. You can get double glazed window suppliers through Mint Window & Door Solutions.

Between these window panes is a pocket of argon gas, provided to fill the space. A spacer holds the two panes together, made from structural foam for minimal heat conduction. Coating is also applied, and the type used varies by the climate the window will function within. For example, in cold climates the coating will reflect cold, thereby keeping homes warm in cool weather.

How R Value Tells The Quality

Double glazed windows are also the perfect balance of affordability and efficiency. Their R-value is between 3 and 5, depending on the age, quality of craftsmanship and framing of a given window. R-value stands for thermal resistance. A value of 5-7 is considered good.

Granted there are window types with a higher R-value (triple and quadruple glazed), but they cost significantly more, and the number of panes required to up the R-value causes them to be bulky in appearance. To ensure that the double glazed window of your choice is of at least 5 R-value, purchase a type with wood or vinyl framing.

Vinyl Framing Is Best To Enhance Windows’ Positive Qualities

Wood and vinyl are both great for insulation. They are equally aesthetically appealing as well. Vinyl is considered better, however, because it requires little maintenance, whereas wood needs to be repainted and refinished intermittently.

Further, vinyl framing is more durable and resistant to warping, chipping, cracking or wear of any sort. You can expect a good vinyl framed double glazed window to last 10+ years, and most have a warranty that lasts that long. Vinyl is also available in a variety of fade-proof, long-lasting colors.
