Fire Rated Glass Block In a Zero-Lot Line

Having Fire Rated Glass Block installed may be a requirement depending on where they will be going or it can be for personal reasons. When houses or buildings are very close together, that is what’s considered a zero-lot line. When structures are in a zero-lot line, the danger and risk of fire spreading from structure to structure is much higher. There are ways to help limit the risk of catching a fire from a structure in very close proximity. One great way to consider is to get Fire Rated Glass Blocks.

Fire Rated Glass Blocks come in fire ratings of 45, 60 and 90. Along with traditional fire rated glass block, there is also Vistabrik, which is 3″ of solid glass block and the toughest product. There is a great variety of styles of block available that are fire resistant and also a few different sizes to choose from. Some fire codes require a fire resistant wall or window when the structures are close. Fire Rated Glass Block will give you ample protection when such a scenario is present. Fire Rated Glass Block is also resistant to graffiti and has added noise resistance. Vistabrik blocks have both of those qualities as well, plus the added benefit of being bulletproof for the highest level of protection.

Choosing fire resistant glass blocks doesn’t limit you to only zero-lot line applications though. You can choose to get them wherever you feel the need for the added protection in case of an unfortunate situation.
