We have seen examples of non-system (third-party) products being promoted for use in performance systems, and although they have performance claims and test evidence, they may not have evidence of being tested in manufacturers’ systems.

This may not come to light until compliance evidence is requested, by which time the product may be installed and any performance warranties from system manufacturers become null and void, with dire consequences.

We recommend that any changes to a system by including third-party products are checked before installation and that a letter of confirmation is requested before proceeding. If you are in any doubt, check with your system supplier.

If you have any questions, please contact Joe Cilia, Technical Director: joecilia@thefis.org
