What is Insulating Glass Spacers?
It’s a good time to talk about insulating glass spacers now, when energy efficiency is more important than ever. Glass spacers, like gas fill, play an important role in the thermal performance of an insulating glass unit. As a result, it is critical to ensure that your spacer technology is both effective and sustainable.
Spacers in an insulating glass unit define the width of the gap between two or more sheets of glass. The primary function of spacers is to maintain a constant gap between the layers of glass.
When it comes to the materials and technologies used to make insulating glass spacers, the glass industry has seen many advancements and changes over the years. Spacer technology is one of the most important factors in ensuring glass performance because it defines the amount of heat and cold that can pass through the glass panes.
When there is a high demand for greener construction materials, more emphasis is placed on glass spacers capable of increasing the energy efficiency of insulating glass.
A Wide Range of Spacer Options in Insulated Glass
Insulating glass spacers are available in a variety of materials, colors, and thicknesses. All three are necessary for an insulating glass unit and have an impact on performance. For example, even a small change in the thickness of the spacer has an effect on its conductivity. Meanwhile, the material determines the amount of heat and cold that can pass through the glass and, as a result, plays a significant role in the energy efficiency of the unit.
When it comes to material, spacers are typically classified as either aluminum or warm edge spacers.
Aluminum Spacers in Insulated Glass
Aluminum spacers were once the most common type of spacer. This material has been available for decades and provides a basic level of performance. This kind of aluminium spacers are cut in desired sizes according to insulated glass size by spacer cutting machine and desiccant material is filled manually with a desiccant filling machine to prevent humidity in finished insulated glass units.
While aluminum is a structurally strong material, it is also an excellent thermal conductor. This means that aluminum spacers allow indoor heat to easily escape outside. Furthermore, the aluminum’s cold glass edges create a temperature difference between the center of the glass and its edges. As a result, condensation forms on the insulating glass units.
Warm Edge Spacers in Insulated Glass
However, rising energy demands necessitated the development of newer solutions. As a higher-performance alternative to traditional aluminum spacers, warm edge spacers made of low-conductivity materials were introduced. This kind of warm edge spacers are bendable spacers and spacer bending is done with automatic spacer bending machine and desiccant material for humidity preventation is filled automatically with automatic desiccant filling machine to insulated glass units.
Warm edge technology has drastically altered the window market. It not only helps to prevent heat loss through windows and improves the unit’s energy efficiency, but it also helps to reduce condensation.
There are numerous warm-edge spacer designs available today. Each reduces the effect of heat loss to varying degrees while providing varying levels of structural integrity.
Stainless Steel Warm Edge Spacers
The properties of stainless steel materials are similar to those of aluminum spacers. Stainless steel, on the other hand, has one-tenth the thermal conductivity of aluminum and improves condensation resistance. Stainless steel spacers, however, are far more conductive than other warm edge spacer options.
Plastic-metal Hybrid Warm Edge Spacers
Warm edge spacers of this type are typically made of plastic materials such as polycarbonates, polypropylene, and others, in conjunction with low metal shims.
Flexible Warm Edge Spacers
Pliable, flexible thermoplastic or silicone-based materials with incorporated molecular sieves have been used to create flexible spacers. Among these, hot melt butyl spacers with no additives stand out the most. TPS® is an excellent example.
TPS® – Advanced Solution for Insulating Glass Spacers
