Why Insulated Glass Units (IGUs) Are Essential for Modern Iron Doors
At Texas Glass Door, we specialize in premium-quality iron doors and thermally efficient door systems designed to elevate both style and performance. One of the most important innovations we offer is the use of Insulated Glass Units (IGUs) in many of our custom glass door designs.
Whether you live in the heat of Texas or experience seasonal changes, IGUs deliver real advantages that go far beyond appearance.
🔍 What Are IGUs?
Insulated Glass Units (IGUs) are made of two panes of glass sealed together, with an insulating air or gas layer between them. This advanced structure significantly reduces heat transfer, making your home or commercial space more energy-efficient.
Many of our iron doors at Texas Glass Door feature IGU panels with optional Low-E coatings and argon gas — combining strength, security, and thermal comfort.
âś… Thermal Benefits of IGUs in Iron Doors
Energy Efficiency for Texas Climates
With our blazing summers and shifting seasons, heat control is critical. IGUs reduce unwanted solar heat gain, keeping interiors cooler without overloading your HVAC system.
đź’ˇ Customers switching to our thermally broken iron doors with IGUs have reported noticeable drops in monthly energy bills.
Year-Round Comfort
IGUs help regulate indoor temperatures throughout the year. In the summer, they block excess heat; in winter, they retain warmth—making your living space more comfortable all day long.
Condensation Control
IGUs minimize condensation inside the glass, which protects door frames and reduces the risk of mold or moisture damage—especially important for homes near the Gulf or in high-humidity regions.
Noise Reduction
As a bonus, IGUs also help block exterior noise—ideal for urban homes or properties near busy roads.
