The GutterStuff Pro foam filter insert is manufactured by GutterStuffÒ  – the original foam filter; patent NO {US 7,208,081}.  Manufactured from POLYETHER resin, GutterStuff Pro's performance is unaffected by UV rays and the harsh natural extremes of heat and cold.  It’s chemical composition gives it “built in” properties of a biocide that inhibit mold and mildew growth - A feature that will not wear out or wash off!
     GutterStuff Pro is very flexible, yet extremely durable….tough enough to withstand any debris, wind, or storm. It can handle children, rocks, trucks…….more abuse than it will ever encounter normally!
     GutterStuff Pro, unlike a sponge, will not retain any water. It drains through completely and is, therefore, unaffected by freezing temperatures. This innovative feature decreases the possibility of winter ice dams and potential leaks into your home.
     GutterStuff Pro’s amazing design allows water 10 TIMES A NORMAL RAINFALL to easily pass through, while preventing debris from entering.  Debris simply dries up and blows away – much in the same way your roof stays clear.  Small debris including (roof) shingle dust will pass through, and be flushed from the gutter.
     It simply works, and unlike other products, can’t be seen from the ground.
