Product Review

Very effective in the wind and seemes to draft better with no wind as well. Thanks Don

vacu-stack

Extreemly poor workmanship. Right out of the well packed box I could tell it was lopsided. Who ever assembled it attached 6 braces going from various places in the copper. There were also 12 bolts through the copper bands where they overlaped. I removed the braces and things almost went back into shape. As it seemed 75% better, I decided to leave the extra bolts in place rather than have rain holes in the top of my cap. The stainless chimney pipe is lapp joined which gives a really poor fit into my butt joined chimney liner. Prepare to use lots of caulk or make a storm collar as I did to keep out water. Wish they sold the vacu-stack as a kit. When I do my second chimney I might just make my own vacustack. All that said, It does seem to work. I live in the Blue Ridge Mountains of VA and the wind does blow in this holler. With winter about over we have had no problem backdraft.

Vacu-Stak Chimney Cap

Works great! Prior to installation, we had a problem with smoke coming back in house and also blowing ashes back in house when wind blows strong from certain direction. We installed this product a couple of months ago and have not had problem since. Thank you for your assistance in this.

Perfect answer to wind issues

Our mini cube fire place was having issues every time the wind blew. It would blow smoke right back down the chimney and fill the house. We put this vacustack copper top on and it changed completely. It creates such good draw now, even with a slight breeze. Thank you

Quality made, but didn't work

I was pleased with the quality construction and overall appearance of this Vacu-Stack Solid Pack Copper Chimney Cap; however, it did not perform as advertised. It didn't even reduce the amount of smoke coming down the chimney pipe into my room during windy conditions. Consequently, I have removed it, am unable to use my wood-burning stove during windy conditions and am looking for a product that works.
