+ Can I cut the expanded polystyrene myself?
Yes, Expanded Polystyrene is easy to cut with a hot wire, hand saw or Stanley knife.
+ Is Expanded Polystyrene paintable?
Yes, Expanded Polystyrene can be painted, but you have to use water based paint only.
+ What type of glue do I use to combine different pieces of Expanded Polystyrene?
Acrylic silicone or water based glue can be used to combine different pieces of Expanded Polystyrene
+ What thickness Expanded Polystyrene do I use for insulation?
It depends on the temperature of the area you want to insulate. The thicker the Expanded Polystyrene,the better the insulation.
+ Can customised forms /shapes be made with Expanded Polystyrene?
Yes, customised forms/shapes can be made with Expanded Polystyrene
+ Can I use Expanded Polystyrene for sculpting?
Yes, Expanded Polystyrene with high densities can be used for sculpting.
+ Is Expanded Polystyrene moisture resistant?
Yes, Expanded Polystyrene resists degrading by water.
+ What does DV stand for?
DV means the density of the polystyrene. Different densities has different uses.
For example: 15DV is for insulation purposes in walls and ceilings. 24DV is used for flooring insulation and 32DV can be used for sculpting.
+ Can Polystyrene Sheets be used for the bottom of Fishtanks or is this a different grade polystyrene?
Expanded Polystyrene sheeting can be used for the bottom of fish tanks. Different densities of Expanded Polystyrene is available depending on the weight of the fish tank.
+ Can you cut Polystyrene Foam, Polystyrene Sheets, Polystyrene Boards and Polystyrene Panels to size?
Yes we can.
The Polystyrene Foam, Polystyrene Sheets, Polystyrene Boards and Polystyrene Panels block sizes are 1200 x 5000 x 600mm so we can cut any Polystyrene Sheet, Polystyrene Board and Polystyrene Panel size within that dimensions.
+ Can Expanded Polystyrene be used for packaging?
Yes, Expanded Polystyrene can be used in order to secure potentially fragile products from being damaged during shipment.
+ How effective is Expanded Polystyrene as a thermal insulation material?
Expanded Polystyrene is extremely effective for this essentially because stabilised air is such a good insulator.
+ Does Expanded Polystyrene absorb water?
Expanded Polystyrene is a closed cell and cannot absorb water. Expanded Polystyrene maintains its shape, size, structure, cohesion and physical appearance. The ability of Expanded Polystyrene to resist the effects of moisture is exemplified by its widespread use in floats, marinas and other applications, which involve full or partial submerge in water for prolonged periods of time.
+ Does age affect the thermal performance of Expanded Polystyrene?
No. Because of its cellular structure Expanded Polystyrene is dimensionally stable and will not settle over time.
Expanded Polystyrene used and installed correctly does not deteriorate with age.
+ Is Expanded Polystyrene strong?
Yes. Expanded Polystyrene is manufactured in a number of classes (or densities) and each density exhibits excellent compressive and flexural strength. The range of densities available enables specifiers to select the most appropriate balance between structural and insulation properties for any building application.
+ How effective is Expanded Polystyrene as an acoustic insulation material?
Expanded Polystyrene has a closed cell structure it offers only a limited absorption of airborne sounds.
+ Is Expanded Polystyrene resistant to chemicals?
Expanded Polystyrene is not resistant to hydrocarbons, ketones, esters, paints containing thinners and solutions of synthetic adhesives. In roof construction requiring hot asphalt, care should be taken to follow recommended installation instructions for hot bituminous asphalt to prevent melting or collapse of Expanded Polystyrene insulation boards.
+ Is Expanded Polystyrene degraded by the sun?
Prolonged exposure to sunlight will cause a slight discoloration (yellowing) of Expanded Polystyrene insulation and cause some surface embrittlement. Even so, the thermal insulation properties will not be affected unless exposure results in loss of thickness of the Expanded Polystyrene Sheets, although the friable surface can make bonding difficult. For this reason, Expanded Polystyrene insulation should be covered to protect it from UV light if it is to be stored in the open for extended periods.
+ Is Expanded Polystyrene durable?
Yes. Because it is inert, organic material it will not rot and is highly resistant to mildew. It also provides no nutritional value to ants, termites and rodents. To prevent damage to Expanded Polystyrene by pests and insects seeking to gain access to the other materials in buildings which provide a food source, Expanded Polystyrene may be coated with a thin cement slurry. Provided Expanded Polystyrene does not suffer mechanical damage or failure of any fittings that may be used, it should have a life equal to that of the building which it is installed.
+ Does Expanded Polystyrene burn?
Because Expanded Polystyrene insulation boards contain a fire retardant additive, they do not present an undue fire hazard when correctly installed. Expanded Polystyrene will burn when in contact with a flame. Due to the presence of the fire retardant additive in Expanded Polystyrene , this flame will self extinguish almost immediately after the fire source is removed.
+ Where can Expanded Polystyrene be used in building construction?
Expanded Polystyrene can be used in almost any application where insulation or a combination of insulation and strength is required. As an insulation material it is used in a number of roof, wall, ceiling and sub floor systems, often used in combination with other materials such as steel (in sandwich panels commonly used for cold store construction), concrete, as an insulation core in tilt up wall panels.
+ Is Expanded Polystyrene cost effective compared to alternative insulation?
Because of the versatility of Expanded Polystyrene and the wide range of applications for which it is suitable, its cost effectiveness compared to alternative materials can generally be accurately assessed only on a case by case basis. In many cases however, particularly where an element of structural strength is required Expanded Polystyrene is the most cost effective insulation material available. Expanded Polystyrene is the only insulation material that in practical economic and efficiency terms can be applied to all areas of building constructions – ceiling, roofs, walls, floors and under slab – to provide superior standards of thermal insulation.
+ What is the most effective way to keep the goods cool or frozen in a Polystyrene Fish or Polystyrene Cooler box?
The most effective way to keep the goods cool or frozen in a Polystyrene Fish or Polystyrene Cooler box is to use dry ice.
+ How long does dry ice last in a Polystyrene Fish or Polystyrene Cooler box?
Dry ice can last up to 4 days in a Polystyrene Fish or Polystyrene Cooler box if it is not left in the sun and opened frequently.
+ How do you pack the dry ice in a Polystyrene Fish or Polystyrene Cooler box?
The most effective way is to pack the dry ice in a Polystyrene Fish or Polystyrene Cooler box is to place it on top in the cooler box. If it is a large Polystyrene Fish or Polystyrene Cooler box you can pack the dry ice in the middle.
+ Goodday,can You make a big polystyrene block with a dimension of 50X60X80cm, we want To use It as a block for gymnast To stand on,To mount bars aswell as for a coach To stand on To assist gymnasts while training,hoe much Will You charge for the block,and Will It ne strong enough To stand on.we Will cover It in vinyl or even ruberise It.please Let me know the price,as we need It very urgently,we live in Limpopo Tzaneen,also advise on delivery costs please.
We supply polystyrene blocks in different sizes, cut to specification. These sizes of 500 x 600 x 800mm will be R 632.00. The density of the polystyrene blocks should be 24DV as this is strong enough to carry the weight.
+ can the cornices be painted - PVC and/or enamel?
Expanded polystyrene cornices can be painted with water based paint.
+ how much is one Polystyrene Panels block
The prices on the polystyrene blocks are different on each size. We can cut the polystyrene foam into different sizes.
+ good morning,I would like to replace my ceiling in my patio with polystyrene , the area is aprox 50m2 A- what thickness and size sheets do you recommend B-how are the sheets joined ? many thanks Clive Spencer
We would recommend that no thinner than the 30mm expanded polystyrene sheets be used. The thicker the polystyrene panel, the better the insulation is. Are you going to remove the existing ceilings completely, if not, the polystyrene panel can be glued onto the existing ceiling.
