Benefits of Warm Edge Glazing in the Built Environment

Glass | 12 January 2023

Warm Edge glazing is an energy-efficient technology that improves the sustainability of buildings. This technology enhances glazing performance by reducing heat loss through the window frame and spacer, increasing the overall insulation U-value. This helps to reduce energy consumption in buildings, resulting in a lower carbon footprint, as well as improved occupant comfort. Warm edge glazing also meets or exceeds current step code requirements for thermal transmittance and condensation resistance. Our team of glass suppliers at PFG Glass is here to help you understand the benefits of warm edge glazing in the built environment.

Metal vs. Non-Metal

Traditional glazing often uses an aluminum spacer to separate the panes of glass. Aluminum is highly conductive and has a very high thermal transmittance rate. Since most energy loss from windows occurs at the edge, the non-metal spacer options available from PFG Glass are far less conductive than aluminum or other options using partial or full metal construction.

Thermal Breaks

Warm edge glass spacers are designed to reduce heat transfer between interior and exterior glass surfaces. This is achieved by introducing a low thermal conductivity material into the space between two glass lites or glass panes in an insulating glass unit (IGU). By reducing this thermal bridging, warm edge spacers increase overall energy efficiency and help reduce heating and cooling costs. This technology has been used for many years in commercial settings, but it is now becoming increasingly popular for residential applications. Thermal breaks are especially beneficial for larger windows and doors that can be particularly vulnerable to heat loss due to their size. They are also beneficial in climates like BC with extreme temperature fluctuations. Warm edge spacers are a cost-effective way to improve energy efficiency and can help reduce the environmental footprint of any building.

Warm Edge, Condensation and Asthma

Warm edge technology is an innovative step forward in improving window performance that helps create a more energy-efficient and healthy living environment. It not only reduces the temperature differential between centre of glass and edges of IG units, but it also lowers heating and air conditioning requirements, which can reduce carbon emissions and operating expenses. In addition to these benefits, it minimizes condensation on sealed units, reducing mould growth risk even further and making it an essential consideration for healthcare buildings or anywhere with people who suffer from respiratory conditions like asthma.

Warm edge glazing is an important tool for architects and builders looking to create green buildings. It provides energy savings, improved comfort, and compliance with step code regulations.
