Double-glazed windows are very popular nowadays. A double-glazed window has two panes. This makes the window more durable and provides insulation. A pocket of argon gas is placed between these two window panes to fill in the gap. For minimal heat conduction, a spacer is made of structural foam to hold the panes together.
The type of coating used depends on the climate in which the window will operate. In cold climates, the coating will reflect cold light, keeping homes warm during cool weather. Double-glazed uPVC windows in Sydney offer the best balance between efficiency and affordability.
The R-value of double glazed windows is 3 to 5, depending on their age, craftsmanship and framing. R-value is a measure of thermal resistance.
There are window types that have a higher R value, but these windows cost more and look bulkier due to the increased number of panes needed to increase the R-value. Double-glazed windows with vinyl or wood framing will ensure that they have at least 5 R value.
Both vinyl and wood are great insulation options and both are equally attractive. Vinyl is preferred in Sydney because it doesn't require frequent maintenance. Wood, on the other hand, needs to be repainted or refinished periodically.
Vinyl framing is also more durable and resists warping, chipping cracking, or wear. A double-glazed vinyl framed window can last for 10+ years. Most windows also come with a 10-year warranty. Vinyl comes in many fade-proof and long-lasting colors.
