GutterCare is an exterior grade foam,
not a sponge.
Understand that there are huge differences in foam products that are being offered for gutter protection. GutterCare is a high tech open celled (so as not to hold water like a sponge) exterior grade, polyether foam constructed to rigid standards. Two important criteria's for foam gutter protection are porosity (PPI) and stiffness (ILD). Insuring the foam is porous enough to allow vast amounts of water to pass through it and stiff enough to endure the weight of ice and snow. Since GutterCare is an open celled construction, it will not hold water. If it doesn't hold water, it won't freeze into a block of ice and expand. In fact, because it's black it absorbs the radiant heat of the sun, it's one of the first things to melt so your gutters will keep flowing.
Notice where the snow is melting?
