In my efforts to achieve energy savings and seal the air leaks within the ceiling air vent opening, I was unable to secure the vent register sufficiently to the ceiling without there being any gaps between the register and the ceiling drywall.
So, what to do?
For better or worse, I decided to try caulking. I thought that not only would caulking seal the gaps along the edges of the vent register between it and the drywall ceiling, but once dry the caulking would hold in place the end of the register which was between 1/4 and 1/2 inch away from the ceiling.
From my efforts to seal air leaks on the outside of my home this past fall, I still had some of the DAP 3.0 Advanced All-Purpose Sealant.
In reading the product label, this type of caulking was all-weather, suitable for indoor or outdoor use, would not crack or shrink and is paintable (for later finishing touches) and had a lifetime guarantee. As well, again per the product label, the application temperature range was from minus 35 to 140 degrees Fahrenheit.
So, I proceeded to apply the caulking onto the drywall such that when the vent register was pressed against the drywalled ceiling it would sink into the caulking.
How did it go?
It worked fine, except that I needed something to hold up the vent register until the caulking sufficiently dried. Now, don’t laugh, but here was my solution to hold the register in place.
I left the step ladder and all of the books, etc. on top of it overnight, checking every once in a while to make sure things were still OK.
The next day, once I removed the books, etc. from the step ladder, the vent register indeed held firm.
This then allowed me to place the vent blocker onto the metal register to stop the hot air from the furnace from heating the mostly unused room.
So, a few unique techniques in my attempt to save a few dollars … hopefully a lot of dollars over time … through reduced heating bills in the winter and air conditioning bills in the summer at minimal cost. I hope this helps you and gives you some ideas if you have this similar situation in your own home.
