Durability

The IBP Glass Block Grid System, unlike mortar installations, allows both for building movement and for expansion/contraction of glass block and surrounding materials. The result is a glass block installation that retains its beauty and integrity over time.

Versatility

With the IBP grid system, it's easy to achieve a new effect simply by replacing existing glass block with a new pattern or color. Again, this replacement process takes only minutes and requires no special tools or labor.

Security

The IBP Glass Block Grid System offers the same advantage as security bars, making it one of the most secure components of any building structure. Even if block are broken and removed, the grid system performs like burglar bars and impedes entry.

Insulation

The acceptable standard, according to the American Architectural Manufacturers Association (AAMA), for a double-pane window is .69. The IBP Glass Block Grid System has a U-value of .49, more than 25 percent better than the accepted standard. Additionally, this system has an air and water infiltration rate of 0.00.

And speaking of insulation...

Traditional windows and skylights transmit more than light. They transmit or possibly amplify sounds from raindrops, hailstorms, traffic, and aircraft. When the IBP Glass Block Grid System is utilized, sounds are subdued and muted by the mass of the block. Light passes freely, but sound doesn't.

Ease of repair

To replace a damaged block, a maintenance person simply cuts away the sealant, removes the block from the grid, inserts the new block, and reseals. Skilled labor and special tools aren't required, and the repair process takes only a few minutes. To replace a damaged block in a mortar installation, a skilled mason must carefully chip out the mortar and replace the block. When the new mortar dries, it may or may not match the existing mortar.
