Why Thermal Insulation Matters in Window Design
As architects and designers, we understand that energy efficiency and sustainability are at the core of modern building projects. High-performance glazing solutions have become essential for improving thermal insulation, ensuring energy savings, and maintaining aesthetically pleasing designs.
At Optimum Window, we offer thermally broken steel windows with advanced glazing options that meet the highest standards for insulation, durability, and design flexibility.
If you’re specifying high-performance windows, understanding the best thermal insulation glass options is key.
What Makes Glass Energy Efficient?
The right combination of materials, coatings, and construction methods ensures superior thermal performance. Here are the key factors to consider when selecting thermally insulated glass:
1. Triple-Glazed Glass for Maximum Insulation
- Provides better thermal efficiency than double glazing.
- Reduces heat loss in winter and heat gain in summer.
- Featured in our RTS430 Thermally Broken Steel Windows, which offer U-values as low as 0.19.
2. Low-E Coatings to Control Solar Heat Gain
- Reflects infrared heat back inside during colder months.
- Keeps interiors cool by reducing solar heat absorption.
- Our RTS430 and 6500 Series windows are available with Solar Ban 70, Sungate 500, and Pilkington Solar E coatings for enhanced performance.
3. Argon or Krypton Gas Between Panes
- Adds an extra layer of insulation by reducing thermal conductivity.
- Helps maintain consistent indoor temperatures.
- Available in our 6500SB Series, which features high-performance glazing solutions.
4. Warm-Edge Spacers to Reduce Heat Transfer
- Prevents condensation and improves energy efficiency.
- Reduces the risk of cold spots around window edges.
- Used in our RTS430-FX Fixed Window Series, designed for modern energy-efficient projects.
5. Thermally Broken Frames for Structural Performance
- Minimizes heat transfer through the frame.
- Ensures better acoustic insulation and structural stability.
- Our RTS430 and Flex 6500SB Series utilize fully welded, thermally broken steel for optimal insulation.
The Best Thermally Insulated Glass for Different Applications
1. Residential Homes & High-End Developments
For luxury homes, energy-efficient glazing is non-negotiable. Our RTS430 Thermally Broken Steel Series offers:
- Triple-glazed options up to 1 3/8” thick.
- Sleek, thin sightlines without compromising insulation.
- Custom finishes for premium aesthetic integration.
2. Commercial & Mixed-Use Buildings
Developers and architects designing commercial spaces need windows that balance design, durability, and insulation. Our Flex 6500SB Series is the ideal solution, offering:
- Large glazed areas with excellent insulation & acoustic performance.
- NFRC-rated thermal performance to meet building code compliance.
- Multi-point locking systems for enhanced security.
3. Historic Restoration & Landmark Buildings
Preserving the historical integrity of buildings while improving energy efficiency is a challenge. Our Hot-Rolled HR4500 & HR4700 Series provide:
- Authentic steel window profiles with modern insulation technology.
- Glazing options from 3/16” to 1 1/8” to suit various restoration needs.
- Custom color matching for a seamless look.
