Curious About Why The Door Threshold Has Been Lowered?
Every detail in home construction serves a purpose, and the door threshold is no exception. If you've noticed that the floor under an exterior door panel has been lowered by around ½”, it’s not just a design choice—there’s logic behind it!
This subtle adjustment is essential for two main reasons:
1. Preventing Water Ingress During Rainfall
By slightly lowering the floor portion where the door panel sits, we create an effective barrier against water seepage. During rainfall, especially heavy downpours, water can pool against exterior doors. A lowered threshold acts as a natural dam, minimizing the risk of water infiltrating your home.
2. Keeping Out Insects and Dust
Besides water, a lowered threshold also helps deter insects and dust from entering. The subtle height change serves as a physical barrier, making it harder for bugs and debris to make their way into your living space.
It's worth noting that this detail applies exclusively to exterior doors with outward-swing panels. So, the next time you look at a lowered threshold, you’ll know it’s a small but significant part of what keeps your home secure and comfortable.
