Our manufacturing process

All Jablite construction  products are manufactured at sites with ISO 14001 certification.

Steam is the main ingredient used in the manufacture of Jablite products. The water consumption is low because the water is clean and can be re-used many times in the process.

No solid waste is generated during the manufacturing; any broken or faulty parts that do not pass our stringent quality control standards can be broken up and re-introduced into the process.

Jablite products do not contain and are not manufactured using any substances which are controlled under Montreal or Kyoto Protocols.


Jablite products are 100% recyclable. We collect waste from building projects and recycle it.

Efficient use of natural resources

Jablite products are 98% air; this makes them remarkably resource efficient. Their lightweight nature ensures that less fuel is used when transporting product from factory to building site.

Expanded polystyrene (EPS), a plastic that is obtained from oil is used to manufacture Jablite products. In Europe, the percentage of oil used in manufacturing EPS is 0.1%.


The monomer styrene has been manufactured for more than 70 years and is used in a wide range of products.

Styrene exists naturally and can be found in many foodstuffs including strawberries, beans, nuts, beer, wine, coffee beans and cinnamon.


Pentane, a non-CFC expansion agent is used to expand polystyrene granules into the cellular structure that makes the production of EPS possible.

Pentane is a slightly volatile liquid in the same chemical family as methane, ethane, propane and butane and is continually being formed in natural processes in the digestive systems of animals and the decomposition of vegetables. It is not considered a substance harmful to health by European health authorities.

Pentane does not contain chlorine and therefore does not harm the ozone layer.

No CFC’s (chloroflourocarbons) or HCFC’s (hydrochloro-fluorocarbons) are used in the manufacture of EPS.
