Today, building design must focus on saving energy and protecting the environment. More people want buildings that are comfortable, efficient, and eco-friendly. The Energy Savings 1.1 glass block answers this need by saving energy and keeping the classic glass block look. It combines tradition with innovation, making it a great choice for many projects.

This glass block works well for walls, stairs, or windows, offering both style and strong performance. Whether you want to brighten a space or add privacy, this block does both without losing energy.

Innovation Through Patented Design

The Energy Savings 1.1 block uses a special, patented design to improve insulation and reduce heat loss or gain. It has two chambers inside, each sealed tight to stop air from moving through.

Here’s how it works:

• Inside the block, there are two Low-E coated glass inserts. These glass sheets have a special coating that reflects heat back to its source.
• Argon gas fills both chambers, reducing heat transfer better than regular air.
• Together, this dual-chamber system improves thermal resistance by up to 50% compared to standard glass blocks.

Because of this design, the block helps maintain rooms cooler in summer and warmer in winter. The Low-E coating sends heat away in summer and holds it inside in winter. This makes it a smart choice for buildings focused on comfort and energy savings.

Unmatched Thermal Performance

The Energy Savings 1.1 block stands out for its excellent energy performance. This block has a low U-value of 0.19 Btu/hr·ft²·°F. The U-value measures how well a material insulates—lower is better.

To give you an idea:

• Traditional glass blocks have U-values around 0.49.
• The Energy Savings 1.1 block reduces heat flow by more than half compared to those.

This means the block can help reduce heating and cooling costs significantly.

Here are some options you can choose from:

• Nubio blocks come in two sizes: 8"x8"x3" and 8"x8"x4". They have a soft surface that gently spreads light, offering privacy with daylight.
• Clarity blocks comes in two sizes: 8"x8"x3" and 8"x8"x4". They provide clear views and allow maximum light into a space.

Both types share the same high level of thermal resistance and help create walls or façades that save energy. Using glass blocks like these for large walls was hard before because regular blocks didn’t insulate well. Now, with the Energy Savings 1.1 block, you can design beautiful, light-filled walls that also meet energy codes.

Tested and Trusted

The Energy Savings 1.1 block is not just built well—it has been tested by trusted organizations to meet high standards. These tests show that the block will work well for many years and handle tough weather.

Some of the standards it meets include:

• ASTM C1036, which sets rules for flat glass quality.
• ASTM C1048, for safety glass that is heat-treated or tempered.
• ASTM E2188 and E2190, which check how well the block keeps seals and insulation working over time.
• NFRC Simulation, which verifies the U-value and overall energy performance.

These tests assure designers that the block meets important energy rules such as:

• IECC (International Energy Conservation Code)
• ASHRAE 90.1 (Energy Standard for Buildings)
• LEED (Leadership in Energy and Environmental Design certification)

By choosing this block, builders can meet or exceed these standards, making buildings more efficient and environmentally responsible.

Light and Eco-Friendly Design: A Perfect Balance

One challenge with energy-saving materials is that they often block natural light. This is not the case with the Energy Savings 1.1 glass block.

You get to choose between:

• Nubio blocks, which soften the light coming through, reducing glare and giving privacy.
• Clarity blocks, which offer clear views and let in the most daylight possible.

This means you don’t have to choose between saving energy and having bright, inviting spaces.

Additional benefits include:

• Better control of heat inside the building
• Reduced glare for people inside
• Plenty of natural light for a healthy, pleasant environment
• Helping protect the environment by reducing energy use

Seves glass blocks are also strong and long-lasting. They recycle easily and reduce waste because you don’t need to replace them often. This makes them a smart choice for buildings that want to save resources and lower their impact on the planet.

Ready for Modern Building Design

The Energy Savings 1.1 block is more than just a piece of glass. A smart building material designed for today’s needs.

Perfect for:

• Office buildings that need good looks and energy savings
• Stairwells where natural light and privacy are important
• Buildings aiming for green certification or better energy ratings

These blocks deliver:

• Reliable energy performance
• Tested quality for peace of mind
• Clear or softly diffused views depending on your needs
