- Hang the curtains on the hooks. Make sure the curtains are properly aligned and that the folds are even.
In short, there is no single “best” thermal insulator; rather, the optimal insulator depends on the specific situation. Polyurethane (PUR) has the lowest thermal conductivity of conventional insulators, at around
