Advanced Construction System with High-Density Expanded Polystyrene (EPS) Panels Acts as Permanent Formwork for Concrete, Ensuring Superior Thermal Insulation and Energy Efficiency in Modern Buildings
The new Nudura system is an innovative form of insulating concrete formwork developed to build solid and highly energy-efficient structures. It uses expanded polystyrene foam panels, which fit together to form molds where concrete is poured. After curing, these panels remain fixed, acting as a thermal barrier and contributing to the building’s strength and insulation.
The construction sector is undergoing a transition towards more sustainable and efficient solutions. Within this context, the Nudura Insulated Concrete Forms (ICF) system stands out as a modern and eco-friendly alternative, capable of enabling constructions with excellent thermal performance, reducing or even eliminating the need for traditional heating and cooling systems.
New Approach to Construction
Features and Benefits
They stand out for their functional duality: serving both as mold elements for concrete and as insulation. These blocks are composed of two expanded polystyrene panels, joined by a patented articulated mechanism system. When stacked and secured to each other, they are ready to receive concrete, creating a monolithic structure that offers two main advantages:
-
Scientists transform sawdust into fire-resistant panels, stabilize the compound with an enzyme extracted from watermelon seeds, and turn waste into promising material for construction.
-
Forget concrete: architects are replacing tons of concrete with giant blocks of expanded polystyrene to build the roofs of houses and reduce structural weight by up to 50%, cut costs, improve thermal insulation, and speed up construction.

The Brazilian state enters the center of the global race for critical minerals by starting the construction of the largest underground nickel mine in Latin America, a mineral essential for electric car batteries that the entire world is competing for at this moment.

New CCR concrete paving technology promises roads up to 3x more durable, less maintenance, and cost reduction in Brazil.
- High Thermal Storage Capacity: This allows thermal energy to be retained efficiently, reducing the need for heating and cooling.
- Low Thermal Conductivity: Minimizes heat transfer, resulting in lower energy consumption.
Integrated Technological Innovation
The design of Nudura ICF incorporates four key technologies that simplify and strengthen construction:
- DURAFOLD®: Articulated spacer system that facilitates the transportation and handling of the blocks.
- DURALOK®: With a three-tooth locking mechanism, it ensures a robust connection between the blocks, guaranteeing structural stability.
- DURAMAX®: One of the largest insulating blocks on the market, offering excellent thermal and acoustic insulation.
- DURASENS: Symmetrical design that allows reversibility in four directions, increasing flexibility during construction.
Use Case: Construction in Taupont
Thomas Kerzerho, a prominent real estate investor, chose Nudura ICF for the construction of a 135 m² house in Taupont, highlighting the effectiveness of these blocks in terms of insulation and water resistance. The choice of ICF was strategic to comply with the demanding regulations of RE2020, aimed at improving the energy efficiency of new buildings. Thanks to the ICF, the residence maintains an optimal indoor temperature year-round without the need for additional heating or air conditioning.
Economic and Environmental Impact
The adoption of the system not only increases comfort and reduces operational costs of buildings but also offers a quick financial return. In constructions with high energy consumption, such as hotels, the investment can be recovered in about three years. Although it still uses concrete and polystyrene, materials that present environmental challenges, the technology represents a significant advancement towards more sustainable and energy-efficient buildings.
The Nudura system thus emerges as a modern and intelligent solution to the challenges of sustainable construction. With advantages ranging from thermal insulation to architectural versatility, these blocks have the potential to transform the sector, providing more durable, economical, and environmentally aligned buildings.
