In today’s world, energy efficiency is a top priority in the construction and design industries, with homeowners, builders, and architects seeking materials that not only offer aesthetic appeal but also contribute to sustainable living. The 1919/13 Energy .17 U-Value Glass Block is setting a new standard in energy-efficient building materials. Known as the best-rated energy block on the market, it offers exceptional thermal performance, making it a game-changer for energy-conscious projects.
Understanding U-Value and Energy Efficiency
Before diving into the specifics of the 1919/13 Energy .17 U-Value Glass Block, it’s important to understand what the U-value represents. U-value measures the rate of heat transfer through a building material. It tells us how quickly or slowly heat can pass through a surface. The lower the U-value, the better the material is at insulating against heat transfer, making it more energy-efficient.
For example, traditional glass blocks typically have a U-value of approximately 0.53 BTU/hr ft² °F, which results in significant heat loss over time. On the other hand, energy-efficient glass blocks on the market have previously boasted U-values of around 0.19 BTU/hr ft² °F (equivalent to 1.1 W/m²K). While this was considered a marked improvement in energy efficiency, the 1919/13 Energy Glass Block takes it even further with a groundbreaking U-value of 0.17 BTU/hr ft² °F.
This smaller U-value represents a significant leap in energy-efficient performance. The 1919/13 Energy Glass Block is among the best-rated energy blocks on the market, offering even more effective insulation compared to other energy-efficient glass blocks. With its ultra-low U-value, this block reduces heat transfer more effectively, helping to maintain a stable indoor temperature and cutting down on energy costs for heating and cooling.
This difference in U-value might seem small, but it translates to meaningful long-term energy savings. Buildings equipped with 1919/13 Energy .17 U-Value Glass Blocks can stay warmer in the winter and cooler in the summer, without the need for additional energy consumption.
Aesthetic and Functional Versatility
The 1919/13 Energy .17 U-Value Glass Block comes in two distinct patterns: Wave and Clearview. This variety allows designers to select the block that best suits their project, whether they are looking for a sleek, modern look or something with more texture and movement.
- Clearview Pattern: This pattern offers a smooth, clear surface that provides excellent visibility and light transmission while maintaining energy efficiency. It’s ideal for applications where you want to allow natural light to flood a space while minimizing heat loss.
- Wave Pattern: For those seeking a bit more texture, the wave pattern features a wavy, textured surface that still provides a high level of energy efficiency. This option is perfect for creating privacy without sacrificing light.


These two patterns allow for a high degree of flexibility, making the 1919/13 Energy .17 U-Value Glass Block suitable for a variety of applications, from residential windows and partitions to commercial and industrial designs.
The Best-Rated Energy Block on the Market
The 1919/13 Energy .17 U-Value Glass Block stands out as the best-rated energy block available today. This is due to its combination of low U-value and aesthetic versatility, along with its high durability and ease of use. Builders and homeowners alike can trust this product to provide a high level of performance while enhancing the overall look of their buildings.
In fact, the U-value of 0.17 sets it apart as one of the most efficient glass blocks on the market. Compared to the typical glass block U-value of 0.53 BTU/hr ft² °F, this significant improvement means that buildings with these blocks can benefit from a more energy-efficient design.
