Energy savings with hybrid prefabricated houses

Energy savings and energy efficiency are today among the key criteria when choosing a modern home. Rising heating and cooling costs, together with growing awareness of sustainable construction, mean that investors are looking for solutions that reduce energy consumption over the long term, but without compromising on comfort. The hybrid prefabricated houses developed by Gradat are designed with precisely that goal in mind: to provide a high level of energy efficiency, a stable indoor climate and significantly lower running costs throughout the year.

How the houses achieve high energy efficiency

The energy efficiency of Gradat’s hybrid prefabricated houses is founded on a carefully designed structural envelope that combines a load-bearing steel frame, a timber substructure and a multi-layer insulation system. This approach provides continuous thermal protection without thermal bridges, which is crucial for reducing energy losses. The combination of rock wool as the main insulation layer and additional wood-fibre insulation on the outside ensures a high level of thermal stability. In this way the interior maintains a pleasant temperature all year round, with minimal need for additional heating or cooling. Thanks to this system, the houses meet high energy efficiency standards and perform as low-energy buildings with optimised energy consumption.

Benefits for homeowners

An energy-efficient house translates directly into lower monthly living costs, as the energy required for heating in winter and cooling in summer is significantly reduced. Stable, high-quality insulation allows the interior to warm up quickly when needed, while also keeping it fresh and comfortable during the warmer months.

Beyond the financial savings, this approach to construction also contributes to a greater level of everyday comfort, since the interior maintains a stable microclimate without large temperature swings. At the same time, reduced energy consumption means a smaller impact on the environment, which makes this way of building a sustainable solution in the long term.

Why choose Gradat?

Gradat’s hybrid prefabricated houses are based on the combination of a steel structure and a highly efficient insulating envelope, resulting in a home that is stable, comfortable and energy-efficient all at once. The modern building system used by Gradat delivers long-term energy savings, a high standard of living and reduced running costs throughout the entire life cycle of the house.
