Every building is different, and choosing the right products and systems can be complex. With so many factors affecting building performance, understanding how materials work together is key to making informed decisions.

For over 25 years, Ecological Building Systems has specialised in solutions designed to improve building fabric performance and reduce energy demand. Natural and bio-based materials are central to our range. For us, better building means creating warmer, more comfortable, energy-efficient buildings, while making considered choices about the materials we build with and their environmental impact.

We provide airtightness and windtightness systems, membranes and tapes, natural insulation and a wide range of products and systems for walls, roofs, lofts and floors. Our solutions support both new build and retrofit projects. We bring these elements together to improve thermal performance and airtightness, manage moisture and support the long-term performance of the building fabric.

Technical expertise is at the heart of what we do. Our team includes Passive House Designers and Consultants, architects and building physics specialists. Whatever stage your project has reached, they can provide practical advice and guidance, supported by training, extensive technical information and digital tools.

Our online System Calculator helps you identify required products, estimate material quantities and costs, and explore achievable U-values.

Whether you're improving an existing building, designing a low-energy new build or working towards stringent energy performance standards, we can help you understand the options and find the right solution for your project.
