“People who have used KnoxDoorGuard™
say they’ve never felt safer, or more comfortable at home ever since.”
Our power bill was cut by 40% after we installed Knox Door Guard™ under every door. It keeps in the heat so well that we can turn our heaters off after an hour and it will stay warm the whole night.

Knox Door Guard™ is simple yet effective in reducing energy usage. With a big family like mine, our electricity bills spike especially during the winter months. After buying a couple of Knox Door Guard™, I’ve seen consistent reductions of almost $15 dollars every month.

I have the most unruly neighbours who party until they pass out. The noise drives my family and I up the wall so when we heard about Knox Door Guard™, we bought 15 for every door in our house. The silence now is a blessing.

Living in a wooded area invites all sorts of unwanted guests into the house. Lizards, cockroaches, you name it. My daughter’s phobia was growing out of hand until we used Knox Door Guard™. We haven’t seen any bugs for months since.
