Types of Gutter Guard Sponges
- One type of gutter guard sponge is made from foam. The material is placed underneath the gutter spikes, allowing water to enter while debris is filtered out. Customers can purchase non-treated, top treated or fully treated foam. Treated foam includes a layer of fire retardant chemicals, a germicide to prohibit plant growth and an ultraviolet protectant to protect the material from sun exposure. Retailers recommend loosening trapped debris every six months with a garden hose or leaf blower.
- Another type of gutter guard sponge is a device comprised of a large pipe cleaner to filter debris and a perforated flexible plastic hose measuring about three inches in diameter to guide water. As of July 2011, gutter guard manufacturers charge significantly more for this type of gutter guard sponge than for the other types. Although the systems are made of pieces commonly found in hardware stores, they are molded in special colors to appear different.
- Installation companies claim that cellulose gutter guard sponges can handle large amounts of water. Some guards are designed from material used by the United States Military, the National Aeronautics and Space Administration (NASA) and the National Association for Stock Car Racing (NASCAR). Pieces are custom molded to gutters and designed to last an average of 30 years. Due to the fact that screws and nails are not required for installation, both installation companies and customers consider cellulose pieces visually appealing.
- Green gutter guard designs allow homeowners to maintain an environmentally friendly design scheme. The guards appear similar to celluloid sponges but are specially treated for enhanced air filtration. The Green-Buildings Company evaluates gutter guard systems on their ability to improve building durability, repeal insects with minimal use of pesticides and effectively manage storm water.
