Freeflow®

Freeflow is a range of innovative, high quality PVC-U rainwater systems that are the result ofFreefoam’s culture of continuous innovation and investment in research and development.A20YearExtendedGuaranteeisavailableonallregisteredFreeflowinstallationssubjecttotermsandconditions.Freeflowrainwatersystemsareavailableinsquare,halfround,ogeeanddeepstyles.

Each rainwater system is co-extruded with a white interior and a range of exterior colours -Freefoam’snew innovative solution to theproblemsassociatedwith rapidheatabsorptionandexpansionofgutters.

Widely published test results show that while a white surface exposed to sunshine canabsorb heat and attain a surface temperature 10oC or more over the air temperature, darksurfacescanriseafurther30-40oCandexceedthesofteningpointofthePVC.Onlargecapacitygutters with a large surface area facing the sun, this can be a particular problem. AllFreeflowguttersystemsareco-extrudedwithcolouredexteriorsandwhite interiors. Whiletheinteriorwillbeexposedtosunlightasnormal,itsabsorptionofheatfromthesunandsubsequentexpansionalongitswidthandlengthwillbesignificantlyreduced,thusdramaticallydecreasingtheprobabilityofanyassociatedproblems.

The Freeflow range has been designed to ensure both reliable, leak-free performance andquick installation. In addition, it is compatible with other rainwater systems with a range ofadaptors. Freeflow products come in a range of standard colours including white, black andbrown,whileothercoloursareavailableonspecialorder.
