Thermal Bypasses are very common in many homes. These holes in the customer’s houses are allowing hot or cold air to escape into their homes. When Dr. Energy Saver Central MD realized the problems with thermal bypasses, we created a solution. The solution was to block off the thermal bypass hole, to make sure no air would be able to escape throughout the house. This would be completed by placing a portion of silver glow, which would be measured and cut for the right size to cover the thermal bypass hole. Than they would take a glue gun around the edges to seal off any air still leaking. As you can see in the pictures thermal bypass holes are not always the cleanest, which means these holes are also releasing dirty air into your house.
