Understanding the Need for Under Door Gap Fillers
I found that gaps under doors can lead to several issues, such as loss of heat or cool air, increased energy bills, and discomfort in my living space. Additionally, they can allow dust and allergens to enter, and I was often bothered by the sound from outside. This is why I decided that investing in an under door gap filler was a priority.
