The Thermo Fleece is Dodo's soft-touch insulation layer, made from 95% recycled polyester fibre. At 50mm it packs serious thermal performance into a material that cuts easily, sits neatly in roof voids and curved cavities, and creates no itch or irritation during installation. It's a natural final layer over a closed-cell foam liner — trapping air and adding significant R-value in spaces where rigid foam boards won't fit. Environmentally conscious choice without a performance compromise.
