FireSark by Trade Select: What Perth Buyers Should Check
Share
FireSark by Trade Select is a fire-rated reflective sarking for roof and wall systems where fire exposure, radiant heat, weather resistance and vapour control all matter. It is not a general breathable wall wrap with a tougher name. It behaves differently in the building envelope, so the right question is whether the roof or wall assembly has actually been designed for a reflective vapour-barrier membrane.
For Perth and wider WA projects, FireSark is most relevant when a specification calls for a fire-conscious reflective layer, often around metal roofs, exposed wall systems, bushfire-aware detailing or jobs where standard residential wrap is not enough. If the wall needs to release moisture vapour outward, compare breathable fire-wrap options before ordering.
What FireSark Does In The Build-Up
FireSark by Trade Select is an extra-heavy-duty reflective sarking used in roof and wall applications. Its job is to sit as a protective membrane layer, helping with radiant heat reflection, weather resistance and fire-conscious specification requirements.
The important practical detail is vapour behaviour. FireSark is not selected for the same reason as a Class 4 breathable wall wrap. A reflective vapour-barrier membrane can be useful in the right roof or wall design, but it can be the wrong choice where the assembly needs outward drying.
Good Uses For FireSark
- metal roof or wall systems where reflective sarking is part of the design
- bushfire-aware projects where the specification asks for a fire-rated membrane layer
- roof or wall builds where vapour-barrier behaviour has been allowed for
- jobs needing a tougher foil-facing membrane than a basic domestic wrap
- applications where ember exposure, weather resistance and radiant heat are all part of the selection conversation
On real jobs, this is usually a specification-led purchase. If the builder, designer or certifier has nominated a fire-rated reflective sarking, FireSark may be the right product family to compare. If the brief is only “some sort of wall wrap”, pause and confirm the membrane type first.
Where FireSark Can Be The Wrong Choice
FireSark is usually the wrong shortcut for framed walls that need a vapour-permeable membrane behind cladding. Those walls often need to manage water from outside while still allowing moisture vapour to move out of the wall system. A non-breathable reflective membrane can interfere with that strategy if it is used without the right design.
It can also be more product than a standard domestic wall-wrap job requires. If there is no fire-driven requirement, no reflective-sarking requirement and no clear vapour-control strategy, compare the standard wall-wrap or sarking range before paying for a specialised fire-rated foil membrane.
FireSark Compared With Nearby Options
| Option | Best For | Main Check |
|---|---|---|
| FireSark | Fire-rated reflective sarking where vapour-barrier behaviour suits the assembly. | Confirm the build-up wants reflective sarking, not a breathable membrane. |
| FireSark Micro-perforated | Fire-focused applications where a perforated membrane is being compared. | Check the specified vapour and condensation requirements. |
| Trade Select CeaseFire | Fire-conscious wall-wrap decisions where breathability may matter. | Confirm whether the wall needs to dry outward. |
| Trade Select Sarking HVB | General reflective sarking decisions without a specific FireSark requirement. | Check whether fire rating is actually part of the brief. |
Checks Before Ordering
- Confirm the project calls for fire-rated reflective sarking, not ordinary wall wrap.
- Check whether the wall or roof assembly is designed for vapour-barrier behaviour.
- Review any BAL, ember, facade, roof or wall specification notes before substituting products.
- Confirm roll coverage, laps, wastage and installation access.
- Check whether a breathable fire wrap is the better comparison for framed external walls.
Common Buying Mistakes
The biggest mistake is choosing FireSark because a job “needs fire insulation” without separating membrane function from bulk insulation. FireSark is a membrane. It does not replace wall batts, ceiling batts or roof blanket where the assembly needs bulk thermal or acoustic performance.
The second mistake is treating reflective and breathable membranes as interchangeable. They can both sit behind cladding or under roofing, but they manage heat and moisture in different ways. The correct choice depends on the whole build-up, not the roll name alone.
Before You Order
FireSark by Trade Select is a strong fit when the specification needs a fire-rated reflective sarking and the assembly suits vapour-barrier behaviour. It is the wrong shortcut when the project actually needs a breathable wall membrane or a standard domestic wrap.
Start with the FireSark product page, then compare Trade Select CeaseFire and the fire insulation collection if the specification still needs sorting out.
