Fire Protection Starts With the Detail

Soudal fire rated sealants are selected around a specified construction detail—not simply because a cartridge, foam or cement carries a fire-related designation. Is the opening a linear joint, cable penetration, static void or high-temperature connection? Does it move? What wall or floor system surrounds it? Those answers help determine which product should be considered.

Industrial Shed carries Soudal products including Firecryl FR, Soudaseal FR, Soudafoam FR HY & Firecement HT, giving installers different options across passive-fire sealing & specialist high-temperature work.

The practical rule is simple: establish the construction detail first, then check the product, joint dimensions, substrates & supporting materials against the relevant documentation.

What Are Soudal Fire Rated Sealants?

Fire-resistant sealants, foams & related compounds are designed for particular joints, openings or penetrations where fire & smoke performance forms part of the construction requirement.

They aren't all versions of the same product.

Firecryl FR is an intumescent acrylic sealant for suitable fire-resistant & smoke-tight internal applications. Heat activates its intumescent behaviour, causing the material to expand.

Soudaseal FR uses SMX hybrid polymer technology & remains elastic after curing, providing a different solution where an appropriate fire-retardant joint also needs movement capability.

Soudafoam FR HY is a fire-rated polyurethane expanding foam with high filling capacity for specified static joints, openings & other suitable applications.

Firecement HT sits in a different application area. It is a hard-setting compound for specialist high-temperature sealing around suitable stoves, ovens, fireplaces & similar heat-exposed locations.

Knowing those differences before installation is far more useful than treating every fire-related product as interchangeable.

Why Choose Soudal Fire Rated Sealants?

Picture two openings that look almost identical on site.

One is a static gap through a wall. The other is a construction joint expected to move.

They may require completely different treatments.

Firecryl FR brings intumescent properties to appropriate internal fire-resistant sealing work. Soudaseal FR provides an elastic alternative for suitable fire-retardant expansion & connection joints. Soudafoam FR HY fills appropriate static openings where an expanding fire-rated foam forms part of the required detail.

Firecement HT addresses heat from another direction entirely: instead of accommodating construction movement, it cures hard for suitable high-temperature sealing.

The product choice therefore follows the construction condition rather than the product format.

Common Applications

Linear Gaps Through Fire-Resistant Construction

A narrow gap can look insignificant until it passes through an element designed to resist fire.

Wall-to-wall, wall-to-ceiling & other linear joints need to be assessed against the applicable construction detail. Width, depth, substrate & supporting material can all affect how the joint is treated.

Firecryl FR is relevant to specified fire-resistant & smoke-tight internal applications including suitable joints around concrete & plasterwork.

Joints That Need to Move

Buildings move.

Thermal expansion, contraction & normal structural movement mean some joints can't simply be filled with a material that cures rigid.

Soudaseal FR is an elastic SMX hybrid sealant intended for suitable fire-retardant expansion & connection joints. That makes movement capability a central consideration when comparing it with an intumescent acrylic or expanding foam.

Ask “Will this joint move?” early. It can eliminate the wrong product type before installation starts.

Cable & Service Penetrations

Electrical & mechanical services introduce another challenge: the opening isn't empty.

Cables, trays & other services passing through a fire-resistant element change the geometry of the penetration & may require a particular product arrangement.

Soudal publishes Australian documentation for selected Fire Range systems covering specified cable & tray penetration configurations under AS 1530.4 & AS 4072.1.

That doesn't make every Soudal fire product suitable for every cable opening. Service type, supporting construction, opening dimensions & installation arrangement still need to correspond with the applicable detail.

Static Openings Requiring Foam

Foam earns its place where the documented application calls for foam.

Soudafoam FR HY expands to provide high filling capacity & is intended for appropriate fire-retardant applications including specified static joints & openings.

Straw & gun-grade formats also change how the installer approaches the work. Gun application can provide greater control where numerous openings need consistent placement.

This collection includes a professional PU foam gun for installers working with suitable gun-grade foam.

High-Temperature Joints Around Heating Equipment

A fireplace introduces heat, but that doesn't automatically make it the same problem as a penetration through a fire-resistant wall.

Firecement HT is a hard-setting sealing paste capable of withstanding temperatures up to 1500°C. It is intended for suitable high-temperature applications around equipment such as stoves, ovens & fireplaces.

Because the cured material is hard, it should not be confused with an elastic construction-joint sealant.

Product Selection Guide

Read the Construction Detail Before Choosing the Cartridge

Start with the drawing, specification or applicable system information.

Establish:

► What building element is being protected?
► Is it a joint, void or service penetration?
► Which materials form the opening?
► How wide & deep is it?
► Will movement occur?
► Is backing or supporting material specified?
► Which product arrangement is documented?
► What installation depth is required?

This approach avoids trying to make a product fit a detail it wasn't selected for.

Acrylic, Hybrid or Foam?

Think of the three product types as solving different installation conditions.

Firecryl FR: intumescent acrylic for appropriate internal fire-resistant & smoke-tight sealing applications.

Soudaseal FR: elastic SMX hybrid technology for suitable fire-retardant joints where movement is relevant.

Soudafoam FR HY: expanding polyurethane foam for specified static joints, openings & other documented applications.

None should be substituted purely because another product is unavailable.

Treat High Heat as a Separate Question

Firecement HT illustrates an important distinction.

A material capable of tolerating extreme temperature isn't automatically the correct material for maintaining the fire resistance of a wall or floor penetration.

Likewise, a passive-fire sealant isn't automatically the right compound for a stove or fireplace joint.

Define the problem as fire-resisting construction, joint movement or direct high-temperature exposure before narrowing the product choice.

Check What Sits Behind the Seal

What you can't see after completion can matter just as much as the visible bead.

Backing materials, depth, supporting construction & the geometry of the opening can form part of a documented system.

Don't assume an ordinary backing material can replace the material specified for a particular fire-resistant detail.

Expert Tips

Photograph the opening before closing it up. Where project procedures permit, installation records can help document what was installed before linings or finishes conceal the work.

Record the product used. Product identification is far easier during installation than months later when labels, cartridges & packaging are gone.

Mark different penetration types before starting. Cable openings, linear joints & static voids may look similar during a busy fit-out but can require different treatments.

Measure rather than estimate. A joint that's wider or deeper than expected may no longer correspond with the detail being followed.

Watch movement requirements. A product suited to a static opening isn't automatically appropriate for an expansion joint.

Keep high-temperature sealing separate from penetration sealing. Firecement HT & passive-fire products solve different construction problems.

Don't improvise substitutions. Changes to sealant, foam, backing material or configuration should be checked against the applicable requirements before installation continues.
