HOW TO FIRESTOP FOR LINEAR AND PERIMETER JOINTS

Perimeter wall fire barriers pose unique design challenges.

Like all construction joints, a curtain wall joint is constantly moving and shifting against the building structure.

The joint may also be exposed to weather, outdoor and indoor elements during and after construction.

So when you’re specifying a firestop solution for curtain walls you need to take into account movement, leakage and water ratings to avoid costly retrofitting in the future.

When you’re firestopping the edge of a slab along the perimeter of a building, you also need to choose a firestop system to work with the exterior sheathing of the building.

This could be made of a variety of components such as curtain wall assemblies, pre-caste concrete panels or cold formed steel framing and sheathing.

Our Hilti firestop solutions for linear and perimeter joints include:

• Our Hilti Sealant and Hilti Joint Spray – our most widely used firestop products for edge of slab solutions.
• Our Hilti Top Track Seal – wraps around a track between gypsum board joints and flat concrete slabs.
• A wide range of firestop systems for exterior use.
• We’re also the first manufacturer to offer a patented and tested floor-to-ceiling vision glass system to meet design needs.

Our Hilti firestop solutions are easy to install and easy to inspect.

They also conform to the most stringent international standards, such as ASTM and EN and are code compliant meeting ETA and UL requirements.
