FAQ's

Frequently Asked Questions About Polystyrene Foam Sheets

What are polystyrene foam sheets commonly used for?

Polystyrene foam sheets are lightweight, durable, and versatile. They’re commonly used for wall, floor, and ceiling insulation, garage door insulation, and under-slab thermal protection. Beyond construction, EPS foam sheets are widely used in cool rooms, signage, retail displays, architectural model-making, and event or theatre props.

Are polystyrene foam sheets good for insulation?

Yes. Expanded polystyrene sheets offer excellent insulation due to their low thermal conductivity and compact closed-cell structure filled with air, a natural insulator. They resist heat transfer and moisture, helping prevent mould growth and ensuring long-term energy efficiency in homes, buildings, and industrial applications.

Is EPS foam sheet recyclable?

Yes. StyroSheet is 100% recyclable and is manufactured with recycled material. Foamex collects clean EPS offcuts from building sites and recycles them into new EPS products rather than sending them to landfill.

What makes Foamex a trusted source for polystyrene foam sheets?

Foamex is an Australian-owned manufacturer and recycler of EPS foam, known for meeting strict Australian Standards and pioneering sustainable manufacturing. StyroSheet is made locally, contains no ozone-depleting substances, and is independently tested to ensure performance, quality, and compliance across a range of building and commercial applications.

Do polystyrene sheets contain harmful chemicals like CFCs?

No. StyroSheet EPS foam sheets are manufactured without the use of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), or other ozone-depleting substances. Our commitment to clean, sustainable production ensures minimal environmental impact across the product lifecycle.
