Foamex - StyroSheet Polystyrene Sheets, Foam and Insulation

StyroSheet EPS sheets from Foamex are durable and long lasting; a material of choice that can be used across multiple industries for a range of applications.

Manufactured in Australia from our industry leading Styroboard EPS expanded polystyrene, StyroSheet is renowned for its excellent thermal performance, strength to weight ratio, shock absorption and acoustic benefits. Relatively inert and dimensionally stable, StyroSheet EPS sheets provide no nutritional value to plants or animals. They are safe to handle, easy to install, contain no CFC’s and are 100% recyclable.

As an insulation material StyroSheet can be used for both external and internal insulation requirements across commercial and residential building applications. Suitable for use on steel stud, timber stud, concrete and masonry structures, StyroSheet provides an efficient and economical insulation solution. Weather resistant, with excellent thermal insulation properties and low moisture absorbency, StyroSheet expanded polystyrene sheets help protect against the effects of temperature and noise.

StyroSheet can also be used across retail and creative applications. Highly versatile, it is an economical solution for custom signage, retail displays and even theatre props.
