Here at Queensland Polystyrene Specialists, we were established in 2004 as a small custom packaging business in Brisbane, Queensland Australia. We manufacture our unique range of custom cut products in our Brisbane factory, where we have expanded the capabilities of our products to many uses.
The Best Choice For Insulation
Expanded polystyrene (EPS) has excellent insulation properties, making polystyrene the best choice for insulating everything from a humble garden shed right through to massive commercial-sized refrigerated cold rooms.
EPS insulation is practical, economic, and efficient and is so versatile it can be used for all types of insulation from ceilings, roofs, walls, floors, and under slab it really does provide superior standards of thermal insulation.
Queensland Polsytyrene Specialists has developed products to help homeowners reduce the costs of heating and cooling their homes with polystyrene insulation solutions. We are proud to say that we have customers who have reported massive decreases in their electricity bills since installing our product.
Poly Recycled Queensland (PRQ) is a locally owned recycling company, located in Acacia Ridge. Poly Recycled has been in business for over 15 years trying to help other businesses and the planet by making sure polystyrene and expanded polystyrene are recycled in the correct way.
PRQ has three main goals;
- save business money
- reduce landfill
- help the planet
They are able to achieve these goals by offering FREE dropoffs to their local factory in Acacia Ridge, and by offering business collection services so that polystyrene and expanded polystyrene are recycled in the correct way to help benefit the plant, and reduce the waste in landfills.

What is Expanded Polystyrene
It is a lightweight cellular material consisting of fine spherical shaped particles which are comprised of 98% air and 2% polystyrene. This air is trapped within several closed hollow cells in each particle.
How effective is EPS as a thermal insulation material?
EPS is an extremely effective essential because stabilized air is such a good insulator.
The thermal performance of a material is measured in terms of its resistance to the flow of heat. This thermal resistance is expressed in R-values, the higher the number, the better the insulation.
The R-value of the most commonly used Class (Class SL) is 1.13 for every 50mm thickness. This, 44mm of this Class of EPS delivers an R-value of 1.0
Does age effect the thermal performance of EPS?
No, EPS consists of 98% air and 2% polystyrene, and nothing else. Because of its cellular structure of EPS is dimensionally stable and will not settle over time. EPS used and installed correctly does not deteriorate with age and as such is able to deliver constant R-values for the life of the building.
How effective is EPS as an acoustic insulation material?
Because EPS has predominantly closed cell structure, it offers only a limited absorption of airborne sounds.
Does EPS burn?
Because EPS insulation boards contain a fire-retardant additive, they do not present an undue fire hazard when correctly installed.
Like timber, particle board and other organic building materials, EPS will burn when in contact with a flame. Due to the presence of the fire retardant additive in EPS, this flame will self-extinguish almost immediately after the fire source is removed.
Is EPS subject to Australian Standards?
Yes. Manufacturers when stating the class of EPS and therefore its physical characteristics are required to manufacture to AS 1366, 3, 1992. As such, he properties of EPS required for a application are guaranteed. Where the densities exceed the AS1366 – 3 – 1992 grade levels Queensland Polystyrene Specialists has measured the properties and provides specification sheets for these high-density grades.
At the beginning of 2020 Queensland Polystyrene Specialists (QPS) has been recognized and approved by AUSowned. AUSowned has been established to help support Australian Owned Business by verifying that they are Australian Owned Companies.
The star rating on Queensland Polystyrene Specialist’s badge displays what level of Australian Owned Company that they are. Therefore, three stars mean that QPS is 100% Australian owned, their products and services are conducted in Australia. Furthermore, it also means that Queensland Polystyrene Specialists has no sneaky tricks and have the correct tax paid in Australia, also that none of their profits are sent overseas
