On July 23, at the production and technical base of Glavbolgarstroy in Krivina, the company presented its innovative thermal insulation product, NRG-Foam, developed under the European research program "Horizon 2020". The event focused on the results of the two-year monitoring of houses built with NRG-Foam and explored possibilities for the large-scale application of this innovative material in construction.

The project aims to replace existing insulation materials with multifunctional energy-saving cement foam and has achieved impressive results:

• 25% improvement in insulation capacity
• 10% higher energy-storage capacity
• 10% increase in water and air tightness
• Enhanced cost-effectiveness

Plamena Nenkova, Deputy Executive Director of International Affairs and Business Development at Glavbolgarstroy, expressed the company's commitment to continuing construction innovations and providing sustainable solutions for the future. NRG-Foam is expected to set new standards in the industry and play a key role in creating more efficient and environmentally friendly construction practices. "We developed this project in a consortium with 13 international organizations within the framework of the Horizon 2020 program. We are proud of the quality and innovation achieved, creating a new generation of insulation material in partnership with leading technological and educational communities. Thank you for being with us!" shared Nenkova.

Arch. Veselin Kolev, Executive Director of GBS-Engineering and project manager for Glavbolgarstroy, commented: "The NRG-Storage project is a significant step forward towards a sustainable future. It provides innovative solutions for the construction industry, proving that energy-efficient materials can be both functional and cost-effective. We are confident that these technologies will find wide application and contribute to more sustainable development of our cities."

The monitoring period, which represents the final phase in the development of NRG-Foam, involved the use of sensors and devices to collect data on the performance of the material. This period spanned two calendar years and took place in the demonstration buildings of Glavbolgarstroy in Krivina, as well as on 27 test walls in Germany with the leading participation of the Technical Universities of Darmstadt and Delft.

Prof. Dr. Eddy Koenders from the Technical University of Darmstadt, Germany, who is the coordinator of the NRG Storage project, also took part in the presentation panel. "50% of energy is used for heating and cooling, so it is important to reduce and change this consumption. We can use the temperature amplitude to save energy and use it wisely and efficiently," said Prof. Koenders.
