A practical solution for the prevention of dampness forming beneath boat & RV beds, under cushions, in closets & more. It\'s special material consists of a white spun polymer woven into a large open configuration that is bonded to a breathable white fabric layer, allowing an open layer of air to form. 3/4\" Thickness allows plenty of dry air to circulate. Lightweight and flexible, yet rigid enough to hold its shape indefinitely. The lightweight (4.3 oz. per sq. yd) material is easy to cut with scissors, can be joined to create extended widths and is virtually maintenance free, but easy to clean and dry.
HyperVent prevents dampness in three ways:
1. Allows warm air to circulate under the mattress, minimizing condensation.
2. The circulating air promotes evaporation of moisture.
3. Separates the bedding from any moisture that might form.
