On a domestic facade package the material choice is mostly about geometry, finish and fire. On an international one, three more variables dominate: how the panel ships, who installs it, and whose standards the evidence is written against. Weight decides the first, panel design decides the second, and the third decides whether your local certifier will accept the package at all.
This is written for specifiers and contractors sourcing a facade package from outside their own market, comparing GFRC, precast concrete and FRP.
The three materials in one table
| GFRC / GRC | Precast concrete | FRP composite | |
|---|---|---|---|
| What it is | Thin cementitious shell reinforced with alkali-resistant glass fibre | Solid reinforced concrete element | Polymer matrix reinforced with glass fibre |
| Relative mass | Low | High | Lowest |
| Combustibility | Non-combustible where tested and passed | Non combustible | Mildly Combustible, assessed by performance |
| Complex geometry | Excellent | Possible but expensive | Excellent |
| Reads as | Concrete | Concrete | Whatever it is finished as |
| Shipping cost driver | Volume | Mass | Volume |
Shipping: volume or mass
Sea freight prices on whichever fills first, the container’s volume or its payload. That single fact reorders the comparison.
- Precast fills the payload. A solid concrete element hits the container weight limit long before it fills the space, so you ship air at the price of concrete, and you pay it again on every inland leg.
- GFRC and FRP fill the volume. Thin shells can be nested, stacked and crated efficiently, so the constraint becomes cubic metres. Panel design, in particular how well panels nest, then has a direct effect on freight cost.
- Damage risk scales with handling, not distance. The number of times a crate is lifted between factory and facade matters more than the ocean leg. Fewer, better designed crates beat clever packing inside bad ones.
- Design the crate with the panel. On international work the crate is part of the engineering. It is worth asking a supplier how they crate before asking what they charge per square metre.
The practical consequence: a lightweight facade is not just cheaper to lift on site. It is cheaper to move across an ocean, through a port, and onto a truck, several times over.
Install crews and what the panel asks of them
The second variable is who fixes it. On an international package the installer is almost always local, has not seen the system before, and is working from your documents.
- Panel mass sets the plant. A panel a two person crew can position with a small lift is a different job from one that needs a crane and a traffic management plan for each pick.
- Fixings should be adjustable and obvious. An adjustable bracket with a defined take up allowance survives a structure built to local tolerance. A fixing that assumes millimetre accuracy does not.
- Number everything. Panels delivered numbered, sequenced and matched to a setting out drawing remove most of the interpretation risk.
- Trial assembly in the factory. Complex assemblies fitted together before dispatch save the discovery happening on scaffold in another hemisphere.
Standards: whose evidence, and will it be accepted
This is where international facade packages most often come unstuck, and it is a document problem rather than a material one.
| Region | Typical fire evidence asked for |
|---|---|
| Australia and New Zealand | AS 1530.1 combustibility, AS 5637 Group Number, AS 5113 full scale facade test |
| United Kingdom and Europe | EN 13501-1 reaction to fire classification, BS 8414 with BR 135 for facade systems |
| United States | ASTM E84 surface burning characteristics, NFPA 285 for exterior wall assemblies |
The tests are related but not interchangeable, and a certifier in one jurisdiction is not obliged to accept another’s classification. Three rules follow:
- Ask which classifications the supplier already holds, by name and number. Not “fire rated”. The standard, the classification, the laboratory and the date.
- Establish early whether local testing will be required. If it will, it is a long lead item and belongs in the programme, not in a variation.
- Engage the fire engineer before the material is selected, not after. On a performance based facade this is the single decision with the longest tail.
GFRC has an advantage here that is easy to miss. Because it is cementitious, non combustibility is a material property that travels relatively well between jurisdictions, even when the specific test does not. A combustible facade material carries a documentation burden in every market it enters.
Warranty across borders
A warranty is only as useful as the entity standing behind it and the law it is enforceable under. Worth settling before award:
- Who issues it. The manufacturer, a local subsidiary, or the installing contractor. These are very different covenants.
- What it covers. Material defect is the easy part. Colour stability, surface degradation, fixing performance and workmanship are usually where the argument is.
- What voids it. Installation by others is the common exclusion on an international package, which is precisely the arrangement most international packages use.
- How a claim is made. Jurisdiction, process, and who inspects.
- Whether replacement panels will exist. Ask whether tooling is retained, and for how long. On a bespoke facade, a warranty without retained tooling is a promise to make something from scratch.
Choosing between the three
- Choose precast when the element is structural, the geometry is simple, and it is made close to site. Precast does not travel well.
- Choose GFRC when you want the concrete reading and the geometric freedom, and when non combustibility keeps the wall on the simpler compliance path. It ships far better than precast and reads the same from the footpath.
- Choose FRP when weight is the governing constraint, the element is large or deeply three dimensional, or the finish needs to be something other than concrete. Budget for the fire documentation work in whichever market it lands in.
Detail on each material sits on the GRC and GFRC panels and FRP panels pages, the direct comparison is in GRC vs precast concrete panels, and the wider material field is set out in cladding panels compared.
Before assuming a test report will be accepted, use the fire standards atlas to compare fire test regimes by country.
Frequently asked questions
Is it cheaper to ship GFRC or precast concrete internationally?
GFRC, usually by a wide margin. Sea freight prices on whichever fills first, the container’s volume or its payload. Solid precast hits the weight limit while the container is still mostly empty space, and that penalty repeats on every inland leg. Thin GFRC shells nest and stack, so the constraint is volume.
Will Australian fire test evidence be accepted overseas?
Not automatically. AS, EN and ASTM or NFPA test regimes are related but not interchangeable, and a local certifier is not obliged to accept another jurisdiction’s classification. Ask which classifications a supplier already holds by name and number, and establish early whether local testing is required.
Who installs an imported facade package?
Almost always a local contractor. That makes panel mass, adjustable fixings, clear numbering and factory trial assembly more important than they are on a domestic job, because the crew is learning the system from your documents.
What should an international facade warranty cover?
Who issues it and under what law, what is covered beyond material defect, what voids it, how a claim is made, and whether tooling is retained so replacement panels can actually be produced. Installation by others is the most common exclusion and the most common arrangement.
Is FRP or GFRC better for a very large facade element?
FRP, generally, where mass governs, the element is deeply three dimensional, or the finish is not meant to read as concrete. GFRC is the better answer where the wall needs a non combustible material or where the concrete reading is the point.
