FIRESTOP FOR FAÇADE

Curtain Wall

Siderise curtain wall fire stop systems (CW-FS) offer an extensive range of solutions for fire stop, smoke stop and sound barrier requirements in all architectural cladding panel applications.

Curtain wall fire-stop solutions comprise a range of factory-engineered fire-stopping and smoke seal systems for horizontal and vertical compartmentation, and perimeter barrier systems for spandrel protection. They are designed to inhibit fire, and smoke from spreading floor-to-floor, compartment-to-compartment, and from breaking out through the spandrel panel.

They also serve as an effective sound barrier for noise control (25 Rw(dB)) and are complemented by a suite of acoustic treatments to further reduce sound transmission via the perimeter joint and mullion profiles.

Key Benefits

Fire Performance

Have been tested to EN 1366-4, En1364-4 & ASTM E2307 with a non-combustibility classification of ‘A1’ to EN 13501-1

Operation

The materials can be either supplied as pre-cut units to suit a specified void size or in sheet form for cutting on-site.

Measure the cavity width(s) for horizontal cavities. Cut the sheets into strips, allowing an additional 10% for compression fit and dry smoke seal.

Bend and insert the Z-brackets into the CWFS material’s side, ensuring that the top of the bracket is flush with the top of the material. Brackets should be 600mm apart.

Fit the CWFS Strip into the cavity, flush with the top of the slab. Drill fixing holes and fitting the brackets into the slab. Tape all butt joints with Siderise® foil tape on the top side only.

Open Ventilated Façade

Siderise RH and RV ‘Open State’ Cavity barriers have been specifically developed to meet the requirements for the cavity barrier used in drained and ventilated facades. It ensures the system will drain any moisture within the facade construction while maintaining airflow in the event of fire which provides an effective hot smoke and fire seal.

Siderise RV vertical cavity barriers for rainscreen cladding are used to fulfil the void between the external envelope and internal structure. By fully sealing the void, they assist ventilated facade to function by maintaining air-pressurisation compartmentation. Most Importantly, their unique stone wool lamella core enables the vertical barriers to accommodate the serviceability movement which is normally associated with rainscreen facades.

The leading edge of the horizontal cavity barriers was encapsulated in a weather-resistant polymer film. As standard, the film is black so as to register as a ‘shadow-line’ behind open joints in the cladding.

Product Fire Performance

SIDERISE have tested horizontal cavity barriers with 25mm and 50mm air gaps to the ASFP TG19 method. During the tests, the seals achieved full effective closure in under 2.5 minutes. Seal temperature below 180 degrees Celsius during this activation period.

SIDERISE RV Vertical cavity barrier fire performance is based on testing to EN 1366-4: 2006 + A1:2010. The tests have been undertaken to assess the ability of the vertical cavity barrier products to reinstate the fire resistance of a lightweight aerated concrete supporting construction.

System Fire Performance

SIDERISE vertical and horizontal cavity barrier products have been in several large-scale system tests such as BS 8141 and NFPA 285.

Operation (Example of RH50)

RH50 horizontal cavity barrier is fitted with the plain mineral fibre edge against the structural wall.

A 50mm (+- 5mm dimension may alter with specific design criteria) clear air gap should be left between the front edge of the cavity barrier and the rear surface of the rain screen facade.

Adjacent lengths of the horizontal cavity barrier should be tightly abutted to prevent gaps.

The top surface of the joint should be sealed with SIDERISE FOIL TAPE.
