Fire wraps perform in a similar way to collars except they do not have the metal shell. This means that they need to be installed inside a solid construction – such as a concrete wall or floor. The concrete effectively works in the same way as the metal shell on a collar, to stop the intumescent expanding outwards. Fire wraps can be a very cost-effective solution, as long as you have the right installation requirements suited to this product. Our Pacifyre® FPW Fire Protection Wrap is ETA approved and has a self-adhesive layer for easy installation.
