Reduce Condensation on Boats

Keep your boat cabin dry with Genuine HyperVent. It's far and away the best product to reduce marine condensation. Mac's Upholstery sells and installs Genuine HyperVent for boats and other applications.

Boaters everywhere face a common problem – condensation inside the cabin. Onboard condensation is more than a nuisance. Unwanted moisture not only damages furniture, gear and equipment, it spawns unhealthy mold and mildew.

The problem is typically caused by temperature differences in places where air circulation is poor.

Poor Air Circulation

Warm cabin air holds more moisture than cold air. When warm air inside the cabin cools down, it can't hold as much moisture. Excessive humidity collects on cool surfaces. Without proper air circulation, moisture pools on bunks, lockers and bulkheads.

Genuine HyperVent Works

Genuine HyperVent -- a spun polymer bonded to a breathable fabric -- solves the problem by allowing plenty of air to circulate in places where stagnant water collects. Best of all, you can use it almost anywhere; Genuine HyperVent's sturdy ¾ inch polymer loops don't compress under heavy loads.

Proper Installation

Use a scissors or knife to trim a sheet of Genuine HyperVent to fit your application. Then install Genuine HyperVent with the loop side down and the cloth side up. Its woven polymer will not scratch standard surfaces.

Reduces Moisture Damage

Genuine HyperVent's manufacturing process is the secret to its effectiveness. The stiff matrix is 95% open, allowing air to freely circulate throughout the material while supporting the weight above. The mat is lightweight and flexible yet rigid enough to hold its shape indefinitely.

Fights Mold & Mildew

Genuine HyperVent reduces dampness and the dangers associated with too much moisture such as mold and mildew. It accomplishes this is two ways: 1) it improves the sleeping surface by providing space underneath the mattress for warm air to circulate, 2) the circulating air promotes evaporation.
