Did You Know?
1. The door threshold, also known as a door saddle, was originally designed to prevent drafts and maintain temperature control within the home. However, it also served as a barrier against insects, rodents, and small animals who might try to sneak into the house.
2. In the late 19th century, door thresholds were commonly made from a material called “hornbeam.” Hornbeam is a type of hardwood that is extremely durable and resistant to decay, making it an ideal choice for withstanding heavy foot traffic.
3. The term “threshold” actually originates from the Old English word “threscold,” which means the plank or stone placed under a door. It was believed that crossing this “threscold” would bring good luck and protect the household from evil spirits.
4. The world record for the longest door threshold was set in 2012, measuring an impressive 534 feet (163 meters). This unusually long threshold was installed in a museum and featured historical facts and artwork engraved along its entire length.
5. While most door thresholds are uniformly straight, there are some innovative designs that can add flair to your entrance. From arched thresholds to custom carved patterns, these unique door thresholds can serve as a stylish statement piece for your home.
Importance Of Replacing A Damaged Door Threshold
Replacing a damaged door threshold is crucial for both safety and aesthetics. An exterior door threshold serves as a barrier against cold air and moisture, providing insulation for your home. When the threshold becomes damaged, it compromises this insulation and can lead to increased energy consumption and higher utility bills. Additionally, a damaged threshold can negatively impact the overall appearance of your door and entryway, reducing the curb appeal of your home.
Moreover, it is important to note that most exterior door thresholds have a corresponding sill beneath them. Therefore, if the threshold is damaged, it is highly likely that the sill is also affected. The sill, designed with a beveled edge to drain water away from the house, plays a vital role in preventing moisture infiltration and protecting your home’s interior. Neglecting to replace a damaged threshold can lead to further deterioration of the door framework and potential water damage to the surrounding areas.
