How Does Thermoplastic Spacer (TPS) Improve Sealing System

by KE JIAYI 08 Jun 2023 0 Comments

Insulating glass units (IGUs) have revolutionized the world of windows and glazing, providing enhanced thermal insulation and soundproofing capabilities for buildings. However, ensuring the longevity and optimal performance of IGUs requires a comprehensive understanding of the factors that can impact their lifespan. In this article, we delve into the various factors that affect the life of insulating glass and explore strategies to maximize their durability.

From the quality of the sealing system to the choice of spacer material, several critical elements contribute to the longevity of IGUs. Additionally, environmental factors, such as temperature fluctuations and UV radiation, can pose challenges to the sealing system over time. Furthermore, proper installation techniques, regular maintenance, and adherence to manufacturing standards play crucial roles in ensuring the extended lifespan of insulating glass.

By examining these factors and implementing appropriate measures, builders, architects, and homeowners can optimize the performance and longevity of their IGUs. Join us as we unravel the intricacies of insulating glass and explore practical approaches to enhance their lifespan and energy efficiency.

What is TPS?

Thermoplastic spacer (TPS) is a crucial component in the sealing system of insulated glass units (IGUs). Unlike traditional metal spacers, TPS is made from a durable and flexible thermoplastic material that offers several advantages in terms of performance, energy efficiency, and longevity.

How Does the Environment Impacts Insulating Glass?

Insulating glass is designed to provide thermal insulation and soundproofing properties, making it an ideal choice for windows in both residential and commercial buildings. However, environmental factors can significantly impact the performance of IGUs over time.

Exposure to temperature variations, humidity, UV radiation, and other atmospheric conditions can lead to the degradation of the sealing system, compromising the insulating properties of the glass. This can result in heat loss, condensation, and reduced energy efficiency.

What Factors Affect the Life of Insulating Glass?

Several factors can influence the lifespan of insulating glass. The quality of the sealing system plays a crucial role in ensuring long-term performance. Traditional metal spacers, although widely used, can have limitations in terms of durability and resistance to environmental stresses.

What Factors Affect the Life of Insulating Glass?

 The life expectancy and performance of insulating glass units (IGUs) can be influenced by various factors. It is important to consider these factors to ensure the longevity and effectiveness of the sealed system. Let's explore some of the key factors that can affect the life of insulating glass:

1. Quality of Sealing System:

The quality of the sealing system is crucial for the long-term performance of IGUs. A well-designed and properly installed seal prevents the infiltration of moisture and air into the glass unit. If the seal is compromised or of poor quality, it can lead to moisture condensation, fogging, and reduced energy efficiency.

2. Choice of Spacer Material:

The spacer material used in IGUs plays a significant role in determining their lifespan. Traditional metal spacers, such as aluminum, are commonly used but can be prone to thermal bridging and potential corrosion over time. On the other hand, thermoplastic spacers (TPS) offer improved durability, flexibility, and resistance to environmental stresses, thereby enhancing the longevity of the glass unit.

 3. Environmental Factors:

 The surrounding environment can have a significant impact on the life of insulating glass. Exposure to temperature fluctuations, humidity, UV radiation, and other atmospheric conditions can cause stress on the glass unit and its sealing system. Extreme weather conditions, such as high heat or severe cold, can accelerate the degradation of the seal and affect the overall performance of the IGU.

 4. Proper Installation:

 The installation process of IGUs is crucial for their long-term performance. Improper installation can lead to air leakage, inadequate sealant application, or misalignment of the glass panes. These installation errors can compromise the effectiveness of the sealed system, resulting in reduced energy efficiency and potential durability issues.

 5. Maintenance and Care:

 Regular maintenance and care are essential to ensure the extended lifespan of insulating glass. Routine inspection of the seal, detection of any cracks or damages, and prompt repairs or replacements are necessary to maintain the performance of the IGU. Additionally, cleaning the glass surfaces with recommended methods and avoiding harsh chemicals or abrasive materials can help preserve the integrity of the glass unit.

 6. Manufacturing Quality:

 The manufacturing quality of the insulating glass unit itself plays a crucial role in its longevity. High-quality materials, precise manufacturing processes, and adherence to industry standards contribute to the overall durability and performance of the IGU. It is important to choose reputable manufacturers known for their quality and reliability.

 By considering these factors and addressing them appropriately, it is possible to maximize the life expectancy and performance of insulating glass units. Proper selection of materials, attention to installation procedures, regular maintenance, and ensuring a high-quality sealing system are key factors in achieving long-lasting and energy-efficient IGUs..

Thermoplastic Spacer Test

 To assess the effectiveness of thermoplastic spacers in improving the sealing system of IGUs, comprehensive tests have been conducted. These tests evaluate various performance aspects such as thermal conductivity, moisture resistance, structural integrity, and overall durability.

 The results have shown that TPS outperforms traditional metal spacers in multiple areas. With its excellent thermal insulation properties, low moisture permeability, and high resistance to environmental stresses, TPS significantly enhances the longevity and energy efficiency of insulated glass units.


 In conclusion, the utilization of thermoplastic spacer (TPS) in the sealing system of insulating glass offers numerous advantages. By addressing the challenges posed by environmental factors, TPS enhances the performance and lifespan of IGUs.

 With its flexibility, durability, and superior thermal insulation properties, TPS acts as a barrier against heat loss, condensation, and air infiltration. This contributes to improved energy efficiency and enhanced comfort levels in buildings.

 As the demand for energy-efficient and sustainable construction solutions continues to rise, TPS stands out as a reliable and innovative choice for enhancing the sealing system of insulated glass. Its proven performance in various tests makes it an ideal solution for achieving long-lasting and high-performing IGUs.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
