Double Glazing Rubber Sealing Strip: Essential Component for Insulated Glass Units
Double Glazing Rubber Sealing Strip represents a critical engineering component specifically designed for insulating glass units in modern window and door systems. This specialized sealing solution features a multi-channel design that creates multiple barriers against moisture vapor transmission while providing structural stability to the insulated glass unit. Manufactured from high-performance EPDM or thermoplastic materials, our sealing strips offer exceptional resistance to UV degradation, temperature fluctuations, and environmental stress cracking. The unique composition maintains permanent elasticity, ensuring long-term sealing performance that prevents argon gas leakage and maintains the insulating air space between glass panes. With precise dimensional tolerances and consistent cross-sectional profile, our sealing strips enable efficient, automated production of double glazing units while guaranteeing reliable thermal performance and condensation resistance.
The advanced engineering behind our Double Glazing Rubber Sealing Strip delivers significant advantages in energy efficiency and durability. The hollow-chamber design not only reduces material usage but also creates additional thermal breaks, significantly lowering the U-value of the complete window system. The deep-groove configuration ensures secure glass retention and accommodates varying glass thicknesses from 4mm to 10mm per pane. Available in multiple hardness levels and color options, our strips can be customized to match specific manufacturing requirements and aesthetic preferences. The integrated desiccant channel allows for easy loading of moisture-absorbing materials, effectively controlling internal humidity within the insulated glass unit. For high-performance applications, we offer specialized versions with reinforced corners, enhanced gas retention properties, and compatibility with structural glazing systems, ensuring your double glazing units meet the most demanding architectural specifications and building code requirements.
Frequently Asked Questions (FAQ)
1. What material is best for double glazing sealing strips?
EPDM rubber is generally preferred for its excellent weather resistance, temperature tolerance (-50°C to +150°C), and long-term elasticity. For specific applications, thermoplastic compounds offer advantages in production speed and corner joint welding. The choice depends on your manufacturing process and performance requirements.
2. How does the sealing strip prevent internal condensation in double glazing units?
The strip incorporates a continuous molecular sieve desiccant that absorbs residual moisture trapped during manufacturing and any water vapor that migrates through the seal over time. This maintains dew points below -40°C inside the air space, preventing condensation under normal climatic conditions.
3. What is the expected service life of these sealing strips?
Properly manufactured units using our premium EPDM sealing strips typically maintain their integrity for 25-30 years. The material's resistance to ozone, UV radiation, and thermal cycling ensures long-term performance without hardening, cracking, or losing adhesion to the glass surface.
4. Can these strips be used for triple glazing units?
Yes, we offer specialized wider-profile strips designed specifically for triple glazing applications. These feature additional sealing chambers and enhanced structural design to accommodate the extra weight and thickness of three glass panes while maintaining optimal thermal performance.
5. How do I determine the correct strip size for my glass thickness?
Our technical datasheets provide detailed sizing guidelines based on total unit thickness and individual glass pane dimensions. Generally, the strip height should equal the total unit thickness, while the channel depth should accommodate the combined thickness of both glass panes plus the primary sealant. Our technical team can provide specific recommendations for your application.
