21 Degrees

Member Company since 2018

21° supplies high-performance products and technical expertise for energy-efficient homes and buildings. Its range of FSC® certified, triple-glazed timber and Aluclad windows and doors are primarily designed for bespoke self-build, custom-build and individual residential projects, including both new-build and deep retrofit schemes. The systems are equally suited to Passivhaus, EnerPHit and other ultra-low energy buildings, while also being specified for selected commercial and social housing developments. With almost 30 years of experience, 21° has been at the forefront of the transition towards low-energy and Passivhaus construction. Alongside its window and door systems, the company provides a carefully selected range of complementary building products, backed by extensive technical support for self-builders, architects, developers and contractors delivering high-performance new-build and retrofit projects.
