What are high performing windows?
High performance windows, sliding glass doors, and environmentally friendly windows are all designed to keep homes warmer in the winter and cooler in the summer. This advanced technology blocks up to 70% or more of the solar heat gain in the summer and reflects radiant heat indoors during the winter.
What are the characteristics of a High performance glass and glazing?
High performance glazing has low U-value, low Shading Coefficient and High VLT (Visual Light Transmittance) and is the ideal choice for today’s energy stressed buildings. 2. Gas filled glazing: To improve the thermal performance of glazing, the space between the glass panes is filled with inert gas.
What is HP glass?
HP Glass. HP (high performance) Glass packages combine Low-E with argon gas fill and Warm Edge spacer options, providing high-performance insulating glass to meet your specific needs.
What is glazing performance?
The better the glazing insulates the interior from the exterior, the less energy is required to maintain a constant temperature difference between the inside and the outside. This aspect of energy efficiency is referred to as thermal performance. This means a lower U-value equates to better thermal efficiency.
Are High Performance windows worth it?
Single pane windows just can not beat the energy performance of quality double pane energy-efficient windows. After installing energy-efficient windows, homeowners can recoup as much as 30 percent of their typical monthly energy bill costs moving forward. It is well worth the investment.”
Why are high performance windows good?
A high-performance window leaves the cold outside and keeps the heat in your home in winter, doing the opposite in summer. This prevents water vapour in the home environment from being settled on the glazing and frames avoiding condensations, dampness, mould, etc.
Is it better to have a higher or lower SHGC?
The lower the SHGC, the less solar heat it transmits and the greater its shading ability. A product with a high SHGC rating is more effective at collecting solar heat during the winter. A product with a low SHGC rating is more effective at reducing cooling loads during the summer by blocking heat gain from the sun.
Is Low-E glass worth the money?
Absolutely! Low-e glass options are definitely worth the investment. For just a few more dollars than standard glass, you get the energy savings and protection from low-e glass. And that little extra cost can pay for itself with the money you’ll save on utility bills!
Are argon windows worth it?
It is generally not a good investment to replace windows just for energy-efficiency purposes. Argon, for instance, typically increases the insulating R-value of a window by only half a point. (Insulated-glass windows, also called double-pane glass, typically have an R-value of around 2.0 to 3.0.
