How to Block Winter Winds in Your Kitchen: Make a Range Vent Cover

| 11/27/2012 8:33:07 AM

The first winter after we replaced our old, nonfunctional rangehood and fan with a very functional microwave/rangehood/vent-fan, we discovered that the fan worked quite well when kitchen ventilation was required, but unfortunately the vents also ventilated much too efficiently during cold weather, sending gusts of frigid air swooping down into the kitchen even when the fan was off.  

As my toes curled up in protest despite two pairs of wooly socks and a pair of fuzzy slippers, I realized that I had some figuring-out to do. After a fairly short period of contemplation, I came up with the following solution, which I feel is one of my very best: 

   Magnetic Adhesive Sheet Label         Adhesive Magnetic Tape 

I bought a 12-by-24-inch roll of Magnetic Adhesive Sheet at a non-denominational arts and crafts store, and cut two 8-by-12-inch pieces off the roll, which allowed plenty of magnetic overlap when stuck over our 5-by-7.5-inch vents. In order to straighten out the semi-permanent curl of the sheeting, the pieces were weighted down and left to straighten out overnight.  

Because it only sticks well to flat surfaces, the magnetic sheeting must be trimmed to fit the situation. Do not remove the paper backing that covers the sticky adhesive surface on the sheeting — after a couple of years, when the backing paper is good and greasy, you can peel it off and stick a fresh piece of paper to the newly exposed adhesive surface.  

This weekend I replaced a set of vent covers because after several years, they had become untenably brittle and sticky. But first I had to degrease the vent filters and the undercarriage of the microwave/rangefan, because rather astonishingly, magnets are not magnetically attracted to thick, sticky layers of grease.

This is an interesting idea for keeping old man winter out of your kitchen. I've never thought to build a range cover like that before. I"ll definitely have to try it out next time it gets cold.
