Find and Fix Temperature Leaks

A thermal leak detector can show you what parts of your garage require insulation. Does your garage door allow in the heat or freezing air?

The Best Budget Detector

The advantage of the Black & Decker thermal leak detector is that it’s relatively cheap and still very useful. The Black & Decker gives you instant feedback on the wall where you are measuring. This means you don’t need to look at the target and back at the screen again It uses the baseline temperature, then it shines green for everything also in that range. A blue light means the target is cooler than the baseline. A red light means the target is warmer.
