The role of a spacer in insulated glass, refrigerator glass doors, and other insulated glass products is highly significant.
Spacers, which can be made of aluminum, PVC, or other materials, are used to separate, support, and seal the functional gas between glass panes. These spacers are bonded between the glass panes with various sealing materials, creating an airtight cavity.
In the business of insulated glass, cooler glass doors, freezer glass doors, and commercial refrigeration, the most common and cost-effective solution is an aluminum spacer with desiccant, and this solution is widely used for many years, and most of the projects with aluminum spacer now.
However, aluminum is a highly efficient thermal conductor, but it is not the best solution for Commercial Refrigerator Glass Door projects, which means that it allows indoor heat to escape easily. Additionally, the cold glass edges caused by aluminum spacers create a temperature difference between the center and edges of the glass, leading to potential condensation issues.
To address the increasing demand for energy-saving solutions, warm-edge spacers made from low-conductivity materials have been introduced as a more effective alternative to traditional aluminum spacers.
One such warm-edge spacer is Super Spacer, which is used to separate the glass panes in insulated glass. Unlike aluminum spacers, Super Spacer is made of a flexible foam material that significantly reduces heat transfer and improves thermal efficiency. Its heat conductive value is only 0.168W/m2·K, making it 950% less conductive than traditional aluminum spacers. The foam material also helps reduce stress on the glass and sealant.
It's important to note that while Super Spacer is a type of warm-edge spacer, not all warm-edge spacers are Super Spacer. Only those warm-edge spacers that meet specific specifications can be referred to as Super Spacer.
The advantages of using Super Spacer include enhanced glass surface temperature, improved resistance to heat flow, minimized stress on sealants, optimal sound absorption, reduced condensation, and flexibility and versatility.
By preventing heat loss at the perimeter of insulated glass, Super Spacer aids in achieving higher Energy Ratings and lowering energy costs. It is a flexible and versatile silicone foam spacer.
