Straw, an abundant and renewable resource, is gaining attention as a sustainable building material in the construction industry. With a growing focus on eco-friendly alternatives, several innovative companies have developed straw-based products designed to reduce the carbon footprint of construction. These products offer excellent thermal and acoustic insulation, and many — when considering A1-A3 LCA modules — are even carbon-negative, making them an attractive option for green building projects. Additionally, straw’s natural properties improve indoor air quality by regulating moisture and reducing harmful emissions, promoting a healthier indoor environment. In this article, we explore some of the key manufacturers featured in the latest revalu collection and their groundbreaking straw-based solutions.
VestaEco is a leader in developing straw-based building materials based in Poland, with products that focus on both sustainability and high performance. Their VestaEco straw boards and insulation boards are made from straw and other natural fibres, offering excellent insulation properties. One notable product is the VestaEco LDF 15, which provides a low Global Warming Potential (GWP) of just 4.346 and minimal fresh water use. This makes it an ideal choice for environmentally conscious builders. VestaEco also emphasises fire safety, with several of their products meeting stringent fire resistance standards.
Strawcture Eco Pvt. is an Indian company, headquartered in New Delhi, which offers a range of AgriBioPanel Drywall Panels, combining sustainability with functionality. These panels are designed for interior wall systems, offering not just insulation but also a unique solution for drywall construction. While specific GWP data is not available for some of their products, their approach to using straw — a by-product of agriculture — helps reduce waste and repurpose natural resources. Strawcture Eco’s panels are ideal for eco-conscious developers who want to reduce their environmental impact while maintaining high construction standards.
EKOPANELY, from their base in Czech Republic, takes sustainability a step further with their EKOPANELY BOARD E40, which boasts an impressive negative GWP of -68.006. These carbon-negative panels actually help sequester more carbon than is emitted during their production, making them a highly eco-friendly choice. EKOPANELY products also offer excellent energy efficiency and low water usage, with their straw construction boards (like the E60/1200) providing natural insulation and contributing to sustainable building design. Additionally, EKOPANELY ensures their materials meet fire resistance standards, such as fire classification F in the EN 13501-1, adding an extra layer of safety.
EcoCocon, based in Slovakia, is known for their Standard and Braced Straw Panels, which offer a balanced combination of energy efficiency and fire safety. With a GWP of 26.348 and an energy mix of 80.13, these panels are a strong contender for builders focused on sustainability. Their products not only meet several fire classifications, but they also support construction techniques that minimise environmental impact, making them ideal for energy-efficient and sustainable buildings. They recently expanded with a new automated production facility in Voderady, Slovakia. This new factory is fully energy-efficient, utilising solar power and innovative prefabrication techniques, and it is part of EcoCocon's strategy to scale up production to meet the growing demand for sustainable, straw-based construction materials
