2. How Does an IGU Work?

• An IGU typically consists of:

• Two or three panes of Low-E coated glass

• Spacer bars(aluminum or warm edge fiberglass)

• Gas filling (argon) to improve thermal performance

• Double sealing system with butyl & silicone for long-term durability

3. Benefits of Using IGUs

• Energy Efficiency -Save up to 30% on HAVC bills with energy-efficent IGUs

• Condensation Prevention - Warm edge insulated glass units stop edge condensation.

• Noise Reduction - Ideal for urban projects, villas, and curtain walls.

• Visual Clarity - High-transmittance WS/MI float glass ensures no green or grey tint.

• Durablility - 30 years without fogging or gas leakage.

4. Types of Insulated Glass Units

• Double Glazed IGU - Standard for residential and commercial projects.

• Triple Glazed IGU - Best for cold climates and passive houses.

• Warm Edge IGU - Avanced fiberglass spacers for next-genergy architecture.

5. Applications of IGUs

• Windows & Villas - Comfortable living and energy savings.

• Curtain Wall & High-Rise Buildings - Architectural aesthetics + performance.

• Pssive House Projects - Required by most certification standands.

Conclusion

Insulated Glass Units(IGUs) are the foundation of sustainable, high-performance architecture. Whether you need double glazed insulated glass of windows or triple glazed warm edge IGUs for passive houses, the right solution will save energy and ensure long-term comfort.
