Curtain Wall - Firestop

Passive Firestop Protection Systems - Facade

That narrow gap between your floor slab and façade is bigger than it looks! Take a 100 x 100 ft. building with the usual 3” void: that’s a tiny footprint, but it adds up to 100 ft squared of open space for gas, smoke and flames to rise from floor to floor. Almost all international building codes now recognize how critical perimeter fire barriers are to the overall building safety plan.

Ambitious designs and strict schedules mean that perimeter fire containment must be quick and easy to install correctly. Acoustic, thermal and movement requirements can’t be ignored either.

With these industry trends in mind, we have developed inventive fire compartmentation solutions that not only help protect lives, but can also help solve other engineering, specification and installation challenges as well. Pre-formed firestop barriers and versatile spray sealants are at the forefront of this new generation

Perimeter wall fire barriers pose unique design challenges to architects and engineers.

Like all construction joints, the curtain wall joint is a dynamic system that is constantly moving with minute shifts against the building structure. Specifying a curtain wall system that does not properly address movement, leakage and water ratings could lead to costly retrofitting down the road Hilti has developed a line of products to meet these requirements along with tested and approved systems to address a wide range of exterior configurations.

FIRST PRE-FORMED SOLUTION FOR EDGE OF SLAB AND CURTAIN WALL FIRESTOPPING

CFS-EOS QuickSeal is a preformed solution that is easy to install, without the need for mineral wool and spray sealants. That means it can be installed in a wide range of temperature and weather conditions without affecting its performance and there is no equipment to haul around or mess to clean up.  CFS EOS QS does not rely on mineral wool compression, so it's fast and easy to inspect and as a preformed device may not be subject to the same destructive testing as may be required for other third-party inspections. The product can be used on joint size ranges from 1.5 inches to 5 inches, with an optional sealant if water tightness is required.

THE ULTIMATE FAST CURE SEALANT

CFS-SIL firestop silicone sealant is a fast-curing and highly elastic firestop sealant for curtain wall or edge-of-slab applications. This silicone-based spray is water-resistant, so – at least when it comes to firestop – your productivity is not weather-dependent. The movement capabilities of CFS-SIL meet leading industry standards, and its water-resistance helps to reduce moisture damage to the joint. After curing, the sealant can easily be painted.

THE TRADITIONAL SPRAY SEALANT

Our traditional, water-based sealant – CFS-SP WB – is a versatile spray for curtain wall or edge-of-slab applications where exposure to water and the elements is not anticipated during the lifecycle of the building. As with other Hilti spray sealants, CFS-SP WB has high-performance movement capabilities that meet leading industry test standards and can easily be painted.

CURTAIN WALL FIRESTOP SYSTEMS FOR FULL VISION GLASS AND UNITIZED BACK PAN

Edge-of-slab fire barrier systems for full vision glass, steel back pan, and other common configurations

Imagine looking out the window of your building and enjoying a beautiful view of the city lights around you.  Imagine the warm rays of sunshine illuminating the office or condo and allowing light to penetrate deeper into the building with a glass façade.  Imagine you can achieve this while keeping the building safer and code compliant.  Imagine no more  

FLOOR TO CEILING VISION GLASS

Hilti is the only manufacturer with a tested perimeter fire barrier system for full vision glass with Intertek listing HI/BPF 120-11.  Previous full vision glass designs were highly dependent on AHJ approval as there was no provision in the code to test these systems.  With the new system, architects and owners now have assurance that their full vision glass design is secured and backed by a tested system.

A NEW KIND OF BACK PAN SYSTEM

Used commonly on unitized and stick built curtain wall systems, the back pan or shadow box systems offers architects, fabricators, and façade installers numerous benefits. Hilti's most recent system Intertek HI/BPF 120-12 is the first and only back pan system that does not require a stiffener.  This translates into huge savings for the contractors. Search through our online library of firestop façade systems by visiting the Firestop Submittal Generator.  If your façade design does not match a tested system, our team of fire protection engineers is ready to assist by providing design assistance and recommendations.
