Energy Efficient Glass Block Panels

Lets in what you want in. Keeps out what you want out.

Energy Efficient Glass Block Panels are aesthetically pleasing and functionally smart. They are engineered, built and tested to the highest standard – so that you can be sure to get quality, performance and easy installation.

Every block works like a traditional energy efficient window. That’s because each block features a low-emissivity coated glass panel sandwiched inside to help keep interiors warmer in the winter and cooler in the summer. Plus, they’re Pittsburgh Corning Glass Block, so they deliver the beauty of dancing light and security that no ordinary window can touch.

Energy efficient Glass block panels let in the sun’s light, but keep out the heat. That’s because each block features a low emissivity coated glass panel sandwiched inside the block that filters out about 70% of total solar energy while still allowing for superior day lighting. And with an insulating U-Value of 0.34 (unframed), these panels can keep HVAC costs in line too. Framed panel as above, has a U-Value of 0.38.

System Specs

Sandwiched inside every block is a low-emissivity coated glass panel. Like traditional energy saving windows, this panel blocks out the sun’s heat and ultraviolet light – to help keep interiors cooler in the summer. In winter, the panel’s improved insulating ability helps keep interiors warmer.

The blocks are framed by a 2-piece aluminum channel. Standard aluminum channel is mill finished, anodized clear or bronze. Powder coating is also available.
