  • Simple and quick to apply
  • Acts as a barrier to radon gas penetration
  • Prolongs the life of buildings

How to bring new and existing buildings up to modern standard

Climate protection and energy conservation are the key social challenges of our time. Industry, science, government and society are called upon to curb the continuing output of greenhouse gases and make more efficient use of existing resources. In response, a variety of approaches and strategies have been developed to protect the environment and climate in the long term. An important factor is improving the thermal insulation of buildings. With a multitude of intelligent products, BASF provides solutions for effective insulation and hence a better quality of life – indoors and outdoors. 

Elastospray®: versatile, easy to apply insulation with top performance

Elastospray® systems are sprayed directly onto the dry and dust-free substrate to be insulated. Once cured, the rigid and robust foam forms a continuous, even insulating layer without joints or gaps, eliminating any thermal bridges. As the material offers excellent adhesion and adapts to any profile, it is suitable for a wide variety of surfaces and shapes.

The versatile options for using Elastospray® range from insulating new-built residential homes to thermal renovation of existing commercial premises. Elastospray® can be used for interior as well as exterior applications such as insulation of walls, floors, soffits and ceilings. Thanks to its closed-cell structure Elastospray® offers an excellent insulation value, airtightness and water-resistance and thus provides a seal against the effects of weathering and temperature. The applied foam is durable, contributes to improve the construction and prolong the life of buildings.

Residents of buildings insulated with Elastospray® benefit from an improved indoor environment and comfort. In addition, the seamless insulation with Elastospray® prevents the infiltration of dirt, allergens and radon gas into the home thus improving indoor air quality. 


Elastospray® LWP – the new generation of eco-friendly spray foam insulation

The Elastospray® LWP systems are the consistent further development of BASF’s proven spray foams. In addition to improving environmental compatibility, they deliver the accustomed superlative insulation, particularly thanks to their closed-cell structure. In residential or commercial buildings, new or renovated, Elastospray® LWP is an assurance of excellent thermal insulation and an outstanding interior climate. Its excellent product properties make Elastospray® LWP the prime choice for all applications demanding speedy, simple, cost-effective and sustainable construction methods.


Superlative insulation performance with the best-possible protection for the environment.

In its bid to curb climate change, The European Union aims to drastically reduce fluorinated gases (F-gases) with high GWP. The associated EU Regulation is targeting a two-thirds cut in F-gas emissions across Europe by the year 2030. For industry, this means substituting hydrofluorocarbons (HFC), as conventionally used as blowing agents in spray foam, with eco-friendlier alternatives. With the rapid development and market launch of the Elastospray® LWP product line in 2017, BASF ranks among the front runners in the industry. We are investing our traditionally strong innovative capability not only in improving the performance of our products, but also in enhancing their environmental profile. The latest outcome of these endeavors in the spray foam insulation sector is the new generation of spray foams that sets new standards of environmental compatibility by using hydrofluoroolefins (HFO) as blowing agent.
