Polystyrene Sheets Auckland

Polystyrene sheets Auckland (more commonly known as Styrofoam) is a versatile construction material. It can be used as insulation in homes, props for movie sets and more.

EPS insulation is combustible in its raw state so it must be treated with fire retardant. This is normally hexabromocyclododecane, or HBCD.

HBCD has been banned in Europe and will be phased out over the next six years. In the meantime, there are alternative products which still use a fire retardant.

Styroboard EPS

Styroboard EPS is made from expanded polystyrene, a white rigid material with excellent compressive strength and thermal protection. EPS is found in coolers, wine shippers, molded end caps and corners on box packaging and even the cups at your office water cooler. It is 98% air and one of the lightest materials in existence – helping to reduce shipping costs and fuel emissions.

It is blown with Pentane which does not produce ozone depleting gases and has a low Global Warming Potential (GWP). As it is fire retardant, it can be used in many different applications. EPS is also environmentally friendly – it does not contaminate ground water or cause adverse health effects. Its closed cell structure minimises air movement and heat conduction, delivering superior insulating performance that saves energy cost, supports sustainable construction and helps to protect the environment. It is a great choice for under concrete slab floors and in timber stud walls, blocks and cladding insulation achieving R-values above building regulations.


ThermaSlab is a slab edge insulation system that has been developed to meet new Building Code requirements for concrete slab foundations. It uses a combination of underslab and slab edge insulation to improve the thermal performance of the concrete slab. This helps you save energy costs and make your home healthier.

EPS is made of small, hollow spherical beads that are tightly packed together to create a rigid and tough insulation board. Its cellular structure makes it moisture-resistant, durable and lightweight. This makes it a popular choice for building applications, including concrete floor slabs and cladding insulation.

EPS is also an environmentally sound option, since it does not contain HCFCs or hydrochlorofluorocarbons (HCFCs). In addition to this, the insulation board does not require the use of hexabromocyclododecane (HBCD), a fire retardant with a very high global warming potential. Furthermore, it can be recycled to become things like planter boxes and toys. These benefits are important to consider when choosing a insulation product for your next project.

High Impact Polystyrene (HIPS)

HIPS is a rigid, impact-resistant thermoplastic plastic that can be used in many different applications. It is lightweight, inexpensive, and easy to process. It also resists a variety of chemicals, oils, and grease.

Its low melting point makes it an ideal material for lower heat applications. It is also durable and can be easily molded into shapes. It has good tensile strength and is available in natural (translucent white), stock, or custom colors.

HIPS has a good moisture vapor transmission rate and can be printed on using lithographic, digital, or offset printing equipment. It is also ideal for screen printing and offers excellent color retention and dimensional stability. It can also be coated with a wide range of finishes for various applications. Several grades are available for specific applications, including flame retardant and antistatic. HIPS is also available in a variety of grades with enhanced environmental stress crack resistance (ESCR). These improved resistances make it perfect for use in food packaging.


Chillguard is a polystyrene foam insulation product that’s well known around New Zealand for being easy to use and effective. It works just like your coffee cup or chilly bin does to keep the temperature in your home stable, so you won’t have to pay extra for heating or cooling.

It is suitable for steel stud, timber framed, concrete and masonry buildings. It’s installed between your joists and it can be cut to size for a snug fit. It’s also resistant to moisture and can be a good alternative for soundproofing.

This product has a wide variety of applications in the construction industry, including insulating cool rooms, constructing props for movie sets and theme parks, as well as providing floatation for pontoons and marinas. It also won’t degrade into harmful substances or contaminate groundwater, which makes it an environmentally-friendly option for your insulation needs. This makes it an excellent choice for a range of commercial and residential projects.
