Modulina Straw Panels

Our product is a prefabricated, load-bearing timber frame panel with compressed straw infill used as insulation material.

Modulina differentiates itself through the use of straw as insulation material, offering a sustainable alternative to conventional building methods.

Established in 2015, Modulina’s production line is based in Lithuania. In 2024, the company expanded to various countries, opening a company in Denmark, completing a project in Germany, and engaging in negotiations with potential partners in Poland, France, Ukraine, Indonesia, Lebanon, Saudi Arabia, and others.

Modulina focuses on decarbonizing construction by maximizing the carbon content in building materials, ensuring longevity. The panels, made of 99% biogenic materials like straw, timber, and plywood, are both structural and insulative, aiding in carbon sequestration and reducing the construction carbon footprint.

Modulina leads the Rebuilding Ukrainian Cities Green Initiative, enabling pilot projects in the public sector to showcase the potential of straw panel technology in post-war community rebuilding.

Straw makes up about 75% of a standard Modulina panel by mass, playing a crucial role in construction. This high straw content maximizes the use of sustainable materials, enhancing insulation properties and adhering to eco-friendly construction principles.

Straw, a by-product of grain agriculture (wheat, rye, rice, etc.), is upcycled in our process, aligning with circular economy principles. Rather than decomposing or being burned, it’s transformed into valuable insulation material, enabling carbon sequestration in our building structures.

Modulina addresses waste management by repurposing about 30% of straw that would otherwise be unused, promoting a circular economy. This approach transforms agricultural ‘waste’ into valuable construction material, reducing agricultural waste and enhancing sustainable material usage in building.

Yes, Modulina’s technology can adapt to use rice straw, offering versatile building solutions in regions where wheat straw isn’t abundant, thus aligning with local agricultural practices.

The embodied energy of straw, a key material in Modulina’s panels, is significantly lower at 4 kW/m³ compared to conventional brick, which stands at 1462 kW/m³. This highlights the energy efficiency of straw, reducing the environmental impact in construction.

Straw walls in Modulina’s construction have a Lambda coefficient (thermal conductivity) of 0.059 W/m²K. For comparison, mineral wool ranges from 0.037 to 0.042 W/m²K. Hence, straw walls need to be about 1.5 times thicker to match the thermal insulation effectiveness of mineral wool.

Straw, combined with wood and clay, helps maintain an ideal indoor humidity level of 40-50%, contributing to a natural and comfortable living environment in Modulina homes.
