"We can't stop the thugs in this neighborhood from breaking out, shooting out, and vandalizing these expensive insulated glass windows we put in the school just last year," the maintenance supervisor said. "Do you have a solution that can stop our cycle of throwing good money after bad?" he said. Unfortunately this is not an unfamiliar concern with owners, managers, and maintenance supervisors of commercial buildings, schools, courthouses, and transit authorities.
How can you stop this cycle of spending, time loss, and frustration? Consider solid glass block window and walls. In this article you'll learn:
1. Why architects and building owners use high security glass masonry units
2. Where to use solid blocks and glass bricks.
3. Options and accessories in security blocks and bricks.
Why architects and building owners use high security glass masonry units
The cheapest way to put up a glass window or wall in a commercial, architectural, or institutional project is with a standard single pane or insulated glass system constructed generally with a vinyl or aluminum framing system. However if your business or facility is located where graffiti, vandalism, bullets, bad weather, noise, or fire are a concern the lowest initial cost window or wall system may not be the answer for achieve the best life cycle costs. The Vistabrik line of solid security glass blocks from Pittsburgh Corning may be what you're searching for. Some reasons building owners have chosen this line of blocks include:
Bullet resistant- These blocks are UL tested and made of 3" thick glass to resist penetration from high impact weapons including 9 mm and .357 magnum bullets.
Reduce vandalism and graffiti - With "non-stick" glass surfaces graffiti is easier to remove and forcible entry is difficult since 8" x 8" x 3" blocks weigh 40 lbs. per square foot mortared together.
Fire resistant - When a higher level of building safety and fire resistance are desired without having to look at ugly wires in the glass, solid glass blocks are a preferred choice. Window panels can be designed with 45, 60, and 90 minute UL approved fire ratings.
Noise reduction - Buildings near train stations, large crowds, traffic, and machinery can be hard to lease and suffer from poor employee productivity. Solid glass bricks have a Sound Transmission Class of 53 and a noise reduction coefficient of .05 resulting in quieter interior spaces.
Cut maintenance costs - Solid glass masonry units can reduce total costs of ownership if you select this durable, hard to break block at the initial stages of the building project - thereby saving ongoing maintenance costs of repair and replacing glass windows and walls.
Where to use solid blocks and glass bricks
Here are some places where solid glass blocks have been used most frequently in commercial, institutional and architectural projects:
Gymnasiums and recreation facilities - one installation is Lloyd Hall in Philadelphia Pennsylvania.
Elevated walkways and parking garages - (check out the walkway at Perry High School in Pittsburgh Pennsylvania and parking garage at Logan Airport in Boston Massachusetts).
Glass block stairwells, shelters, and walls in transit stations, jails, detention centers, courthouses, police stations, and embassies - Solid glass units provide security without giving up light and looks. Some interesting installations include Yankee Stadium Complex for the New York City Transit Authority and the Clay County Detention Center in Liberty Missouri.
Glass block windows in factories and manufacturing buildings - A building owner in Columbus Ohio is planning to use solid glass bricks to replace insulated glass aluminum framed windows that have been getting broken and shot out.
Options and Accessories in Security Blocks and Bricks
If you're looking for a clear view window or wall or need higher privacy, then the selection of solid glass blocks is for you. For a high clarity look there are 8" x 8" x 3", 4" x 8" x 3" and 3" x 8" x 3" sizes available. For higher privacy projects the 8" x 8" x 3" size can be supplied with a stippled face.
The solid blocks are generally mortared together with galvanized panel reinforcing through the horizontal mortar joints (usually every 24") and panel anchors (every 24" as well) to tie the window panels into the jambs or sides of the opening. These glass masonry units also meet tempered glass windows standards due to their strength.
Conclusion
Keeping building costs and security and safety concerns down has never been as important as it is today in our unstable world. Using solid security glass block windows and walls can be one step to provide building owners, employees, and parents with increased comfort, style, security and most importantly - peace of mind.
