Glass Block 4″ Premiere™ Series
Cortina
Cortina combines clear glass with a frozen-ice texture for a distinctive finished surface. The irregular pattern disperses light and provides a high degree of visual obscurity.
Use this clear glass block in a planned window or partition layout. Check the selected size, desired privacy and installation method before calculating the finished panel.

Product Overview
The Cortina pattern gives glass block panels a frozen-ice texture. Its maximum privacy level should be considered alongside the view, lighting and intended use of the space.
Choose among the four listed size/SKU combinations to suit the panel design. The nominal size identifies the module; actual face dimensions are ¼″ smaller in each direction. Confirm the block depth and matching accessory profile before selecting the installation components.
Product Highlights

Very Important Product Questions
What privacy should I expect from the Cortina pattern?
Cortina is listed with maximum privacy. Evaluate a sample under the intended lighting; distance and illumination affect how clearly objects can be seen through the panel.
How do I choose the correct size and SKU?
Select the size option and confirm its matching SKU in Technical Specifications. The four variants share the pattern but have different face dimensions; use actual dimensions plus system joint allowances to plan the panel.
Can I use spacers from a different glass block series?
Do not select spacers by appearance alone. This 4″ Premiere™ product requires compatible block-depth and joint-profile components for the chosen mortar or ProVantage installation.
