Here are some frequently asked questions and answers on Warm Edge Technology.
What is the definition of warm edge?
Warm Edge Technology is a generic term for any spacer bar or system that has better thermal performance than highly conductive aluminum spacer bar.
Aren’t all warm edge technology spacer systems the same?
While we use the generic term WET, there are many different types, some with higher performing attributes than others. Different types include stainless steel; plastic spacers with and without metal backing; tin plated U-shaped spacers; flexible spacers from thermoplastic matrix; butyl-matrix spacers and thermoset structural foam spacer systems.
What are the key performance comparisons that sealed unit manufacturers and fabricators need to research before committing to any of the spacer systems?
There are several key performance indicators but we always advise to take into account all of the following:
- Thermal performance, specifically relating to Window Energy Ratings
- Extensive supply chain & distribution channels to ensure consistent availability of product
- Testing and standards compliancy
- Ease of manufacture
- Application options
- Durability and proven performance
- Comprehensive system e.g. colours, Georgian bars, and simulated divided light system
How large a unit can Super Spacer support?
Units as large as 30 sq. ft. can be made with Warme Edge.
The Benefits of BIEBER “Warm-Edge” Spacer System
The Intercept spacer system features a unique, one-piece metal alloy, U-channel design that creates an effective thermal barrier to help reduce conducted heat loss through the window. Its sealed, one-piece design makes I spacers stronger and better at retaining insulating gas than many conventional designs.
Comfortable Rooms Start With Bieber European Windows
Bieber European Windows are so energy efficient that they keep the edges of the window glass warmer, so your home feels more comfortable in the winter. The temperature difference between the edge of an insulating glass unit with an ordinary spacer, and one with an Bieber Warm Edge spacer system can be dramatic.
