RainTube creates a closed system within the gutter that lets water through but keeps debris out.
The patented RainTube material is pourous and fits snugly into the body of the gutter keeping debris high up out of the water where it can dry out quickly. Water flows in great volumes around and through the tube via thousands of tiny passageways. In most installations, RainTube "crowns" slightly above the top of the gutter creating a slippery aerodynamic surface that removes most debris with a natual breeze. Any remaining stubborn debris can be easily removed with a light brushing or blowing whenever the roof is maintained.
RainTube collects water as fast as an open gutter. In fact, RainTube collects water so fast that in a storm the bottom of the gutter is scrubbed clean as rain passes through. RainTube will not deteriorate and is virtually invisible when in place. Plus, it prevents snow and ice buildup in cold climates and can even be fitted with an optional heating element.
