Fire Resistant Roofing Sheets: What PVC Can Claim

Mr Quyen - Santiago. Posted 14/11/2026

Santiago does not hold a fire rating, class or certificate for its ASA/PVC roofing sheets, so it does not sell them as fire resistant roofing sheets. As a general material fact, PVC contains chlorine and tends to stop burning once the flame is taken away, but that is a property of the plastic, not a fire rating for a roof. If your building needs a rating, ask any supplier for a test report to your local standard and follow your local fire code.

What does "fire resistant roofing sheet" actually mean?

In a building code the phrase only means something when it points to a test. A laboratory tests a sample to a named standard and issues a report with a result, often a class or a rating. Standards differ from country to country, and so do the tests: some measure how a material reacts to a small flame, others how a complete roof covering on its deck copes with fire from outside. A result applies to the product and the build-up that were tested, not to a material in general.

A product listing that says "fire resistant" with no standard, no laboratory and no report behind it gives you nothing to show a building inspector.

Are PVC roofing sheets fire resistant?

Santiago makes no fire claim for its sheets, in either direction. What can be said is general chemistry: PVC contains chlorine, and PVC tends to stop burning when the flame that lit it is taken away. That is why it is sometimes described as self-extinguishing.

It does not make a PVC roof fireproof. Like other thermoplastics, PVC softens and loses its shape when it gets hot enough, and smoke from burning plastic is harmful to breathe. How a roof behaves in a real fire also depends on the frame, the space under it, what is stored inside and how close the neighbouring buildings are. That is why codes test whole assemblies rather than taking a material's word for it.

Is PVC roofing flammable? What the flame video shows

PVC will burn while a flame is held to it. The video below shows grey and red sheets under a flame, then a warehouse roof re-laid in blue. It shows how the sheet behaves under a flame in front of a camera. It is a demonstration, not a laboratory test, and it is not a fire rating.

What should you ask any supplier for?

Ask for	Why it matters
The name and number of the test standard	It has to be a standard your building code accepts
The name of the laboratory	Some authorities accept reports only from certain laboratories
The full report, not a single line from it	The report says exactly what was tested and what the result was
Product details in the report	Thickness, layers and profile should match what you are buying
Whether the material or the roof covering was tested	Roof rules often ask about the covering on its deck, not the sheet alone
Date and product name	They should match the current product and the invoice

These questions apply to every roofing material and every supplier, plastic or not. If a supplier cannot answer them, treat the fire claim as unproven.

Can I have Santiago's sheets tested locally?

Yes. Santiago sends free samples (the buyer pays the courier) in 2.5 or 3.0 mm and in the colour you plan to use, and a laboratory in your country can test them to the standard your project needs. Tell the laboratory exactly which thickness and profile you will order, because a result for one does not automatically cover another.

Where do fire rules matter most on a roof?

Your local fire code decides this, not the roofing supplier. In many places the rules are strictest for factories and warehouses that store goods that burn, buildings close to a boundary or to neighbours, roofs over escape routes and buildings where many people gather. Ask your architect, engineer or local fire authority what your roof has to meet before you choose any material.

Which site precautions apply to any plastic roof?

Finish welding, cutting and grinding on the steel frame before the sheets go up, so sparks cannot land on them.
Keep the roof clear of chimneys, flues, kitchen exhausts and barbecue hoods, and use the detail your code or the appliance maker requires where a flue passes through a roof.
Store the sheets away from fires, hot work and burning rubbish on site.
Do not burn offcuts; dispose of them with other plastic waste.
In a factory, keep hot processes and heaters away from the underside of the roof.

Which documents does Santiago provide?

Document	Available	What it covers
Fire rating, class or certificate	No	Santiago holds none for its sheets
ISO 9001:2015 certificate ICI-23087.D	Yes	The factory's quality management system
Quatest test results	Yes	The properties listed in the report; not a fire rating
Quality certificate (CQ)	With every lot	Product, thickness and lot
Free samples	Yes, buyer pays the courier	Your own checks or a test by a local laboratory

Santiago supplies sheets and accessories and sends installation videos; it does not install, and it gives no structural, wind or fire rating. The design of the building, and its approval under local rules, stays with your builder, engineer and local authority.

What happens when a flame is held to the sheet?

The heat-test short: grey and red sheets under a flame, Mr Quyen on grey sheets at the factory, then a warehouse roof re-laid in blue. It shows how the sheet behaves under heat in a demonstration; it is not a certified fire rating.

Frequently asked questions

Are PVC roofing sheets fire resistant?

Santiago holds no fire rating, class or certificate for its ASA/PVC sheets and makes no fire claim. Any "fire resistant" claim should come with a test report to a named standard.

Is PVC roofing flammable?

PVC burns while a flame is held to it. As a general material fact it contains chlorine and tends to stop burning when the flame is taken away, but that is not a fire rating for a roof.

Is the flame test in Santiago's video a fire rating?

No. It is a demonstration filmed at the factory, not a laboratory test to any standard.

How can I get a fire test for my project?

Ask Santiago for free samples (the buyer pays the courier) in the thickness and colour you will order, and have a local laboratory test them to the standard your code requires.
