Neopor® - the Original for your insulation project

With Neopor®, BASF has succeeded in further developing the insulation classic Styropor®. The grey insulation boards made from the expandable polystyrene (EPS) perform better than conventional EPS and set high standards of quality, as a large number of reference projects throughout Europe have shown.

Planner, architects and builder-owners benefit from insulation made of Neopor® because of the special advantages this material offers. They are crucial for the energy efficiency, cost-effectiveness and sustainability of construction projects:

  • excellent cost-benefit-ratio
  • eco-efficiency: good for budgets and the environment
  • successfully used in numerous reference projects
  • thinner boards, enabling more flexibel plannig and design
  • wide range of applications and design possibilities 


Cradle-to-grave efficiency and effectiveness

BASF produces Neopor® on the form of grey plastic beads, which insulation producers process into boards and specially shaped elements. First steam is applied to foam the raw material, causing its volume to swell by a factor of up to 50. The foamed beads are then fused by applying heat in special moulds to make blocks, boards, or shaped elements. After undergoing this process, products made of Neopor® can consist of up to 98 percent of air. The good thermal insulating properties of air greatly contribute to the outstanding performance of Neopor®. 

It takes energy to make insulation from Neopor®. But this is offset many times over during the product´s service life by reducing the amount of energy needed to heat buildings insulated with it. At the end, insulation made of Neopor® can also be incinerated to extract its energy in the form of heat. 

Insulating is worth it

Make energy improvements to your home with grants for insulation measures

Countries such as Great Britain, France or Germany support homeowners or residential landlords with grants for energy-effficient insulation improvements to your home. Insulation material made of Neopor® reduces your engery use for cooling or heating your house which leads to lower CO2 emissions during the use phase of at least 50 years. With Neopor® insulation material you are eligible for applying state-promoted voucher programms. 

Costs put to the test

The Brunckviertel district in Ludwigshafen, Germany, a workers’ housing estate dating back to the 1930s, was comprehensively refurbished from 1997 to 2006. Coordinated modernization measures in the field of renewable energies and thermal insulation reduce CO2 emissions and save heating costs. External wall insulation featuring materials made of Neopor® formed the heart of the renovation project.

External wall insulation

BuildTog Project in Darmstadt

Create architectural freedom - with energy-efficient and cost-effective construction: this was the objective of the BuildTog project in Darmstadt, Germany.

Using thermal insulation made of Neopor®, it was possible to accommodate the 37 flats in one building envelope with 0.26 W/m2K.
