Plastic is one of the safest insulation materials around when it comes to fire. Thanks to its organic polymer structure, plastic typically refuses to ignite, and, instead, melts. This means, that when used as insulation, it does an excellent job of preventing fire from spreading – avoiding contirbution to damage where possible.
Our material of choice, SupaSoft recycled polyester insulation, is Class E fire safety rated, meaning it melts upon prolonged contact to fire rather than outright incinerating. As such, it poses minimal risk of spreading in the event of a blaze. It takes extreme, prolonged heating for SupaSoft to fully ignite.
