“Can I use manufacturer A’s intumescent sealant with manufacturer B’s fire batt?”

This is a question we often get approached with at Quelfire and the simple answer to it is no. Here is why:

Take a common installation of plastic pipes / insulated pipes penetrating through a fire compartment wall in an ‘oversized opening’. The pipes are generally wrapped with a continuous intumescent pipe wrap (or HPE graphite sealant depending on the application) then fire batt and intumescent sealant is used to provide a complete seal as per the manufacturers instructions. When these products were fire tested, they would be tested together as a system. All installations should be installed as per the manufacturers testing and scope of application. It is highly unlikely that the manufacturer of one product has tested their product in conjunction with another manufacturers product.

So whilst it may be tempting for an installer to use manufacturer A’s sealant and manufacturer B’s fire batt, or similarly manufacturer A’s intumescent fire sleeve with manufacturer B’s fire batt, these products should be tested together and if not tested together, may not perform in a fire, therefore you should not ‘mix and match’ different components from manufacturers.

If you have been told to use materials from different manufacturers in a particular installation, Quelfire would be able to offer advice directly to your client with this regards to let them better understand the requirements and parameters. As a manufacturer we are only a phone call away and will be able to advise which products and systems should be used in which application.
