Natural Hemp Insulation for Sustainable, Breathable Building Performance
At Unity Lime, our hemp insulation range provides a highly effective, natural solution for energy-efficient and breathable construction. Made from renewable hemp fibres, this eco-friendly insulation material offers excellent thermal and acoustic performance while supporting a healthy indoor environment. Hemp insulation is particularly well-suited to traditional buildings, heritage properties, and eco-build projects where breathability, low embodied carbon, and moisture regulation are essential.
Our natural hemp insulation boards and batts are non-toxic, vapour-permeable, and resistant to mould, pests, and decay. They work in harmony with lime plasters, renders, and other natural materials, helping to reduce condensation risk and improve overall building performance. Easy to install and safe to handle, hemp insulation is suitable for use in walls, floors, roofs, and between timber studs in both new-builds and retrofit projects.
As part of our commitment to sustainable building practices, Unity Lime supplies breathable hemp insulation products that meet the highest standards of durability, environmental responsibility, and indoor air quality. Whether you’re restoring a listed cottage, upgrading a period home, or designing a low-impact eco-house, our hemp insulation offers the comfort, efficiency, and sustainability you need.
