What is the lifespan of double glaze vs. single glaze, and what are the main benefits of this?
If designed and installed correctly, double-glazed uPVC windows and doors last approximately 30 years. Quality materials and fitting standards will promote long-lasting windows and doors.
However some studies have shown uPVC can last a lot longer than 30 years.
According to the Water Services Association of Australia's Sewer Drain Code, uPVC pipe is a category A rating, signifying a life expectancy of over 100 years. In other applications such as window profiles and cable insulation, studies indicate that over 60 per cent of them will have working lives of over 40 years.
Repairing and refurbishing existing buildings is far more cost effective than demolishing and rebuilding using shorter-life materials. Installing double glazed uPVC windows and doors reaps long-term benefits during its long lifespan. Households can save money on maintenance and repair costs by installing uPVC. Here are 3 additional reasons why double-glazing is beneficial.
- It’s low maintenance
uPVC needs virtually no maintenance and has a long life span, will not rust or rot or be affected by termites. Fusion welded construction eliminates drafts and water leaks during winter. uPVC doesn’t require any sanding or painting. Homeowners simply wipe clean as required and lubricate locks and latches every year.
- It’s weather resistance
uPVC is engineered to handle extreme weather conditions. The unique elements that make up uPVC windows and doors prevent wear under these conditions. uPVC is designed to be exposed to strong wind, heavy rain and above 40 temperatures and frames won’t warp, rust, fade or rot. uPVC also has salt content so it can be easily installed in coastal areas.
- It decreases power use
Nearly half of household energy is lost through single-glazed traditional windows. uPVC households spend less money on heating and cooling because houses remain at a comfortable temperature year round. uPVC windows keep the house cool in summer and warm in winter, regardless of the temperature.
Double glazing, done right, can last for generations. It can be installed in both new homes and old, traditional homes as well as commercial spaces.
