HYPERVENT 39X50 ROLL PMG

A practical solution for the prevention of dampness (condensation) forming beneath boat & RV beds, under cushions, in closets & more. HyperVent is a special material that consists of a white spun polymer woven into a large open configuration that is bonded to a breathable white fabric layer. This light mesh of polymer does not compress, allowing an open layer of air to form. It is 3/4" thick, allowing plenty of dry air to circulate. HyperVent is lightweight and flexible, yet rigid enough to hold its shape indefinitely. HyperVent prevents dampness in three ways:1. Allows warm air to circulate under the mattress, thereby minimizing an essential condition for condensation.2. The circulating air promotes evaporation of moisture.3. Separates the bedding from any moisture that might form.
