Exterior door thresholds are an essential component of any entryway. They serve as the first line of defense against all kinds of environmental elements, ensuring your indoor space remains safe, comfortable, and energy efficient. Beyond their functionality, thresholds contribute significantly to the overall aesthetic of a property. They can add a polished and cohesive look to doorways.
In residential or commercial settings, selecting the right exterior door threshold is crucial to achieving long-term durability, improved energy efficiency, and enhanced curb appeal. This blog gives you a brief idea about the importance of exterior thresholds and their different types, which will help you make an informed decision as per your requirements.
The Importance of Exterior Door Threshold
Exterior door thresholds are crucial in maintaining our entryways' functionality, durability, and performance. They are more than just aesthetic features; they contribute significantly to energy efficiency, security, and protection against external elements. Here is why exterior door thresholds are essential:
Weather Protection
The exterior thresholds offer the first defense against weather conditions, including rain, snow, wind, and debris. A well-fitted threshold prevents water and dirt from seeping indoors, protecting your flooring and reducing the risk of moisture-related damage.
Energy Efficiency
By ensuring a tight seal at the base of the door, thresholds minimize drafts and air leaks, helping maintain a consistent indoor temperature. This helps enhance energy efficiency by reducing the workload on heating and cooling systems, ultimately lowering utility bills.
Pest Prevention
An adequately installed exterior threshold acts as a barrier against insects and pests. It can seal the gaps at the base of the door, making it difficult for unwanted intruders to enter your home.
Enhanced Durability
Thresholds protect the bottom edge of the door from wear and tear caused by frequent use or exposure to the elements. This helps in increasing the lifespan of both the door and the frame, ensuring long-term performance.
Safety and Accessibility
Modern thresholds are designed to accommodate safety and accessibility needs. Low-profile or ADA-compliant thresholds provide a smooth transition for wheelchairs, strollers, and other mobility aids, ensuring safe and convenient access for everyone.
Improved Aesthetic Appeal
Exterior door thresholds are available in various materials and finishes, allowing homeowners to choose an option that complements the door and home aesthetics well. This enhances the curb appeal of the property.
Noise Reduction
Thresholds help in reducing noise infiltration by sealing the gap at the base of the door. This creates a quieter and more comfortable indoor environment, especially in areas with high outdoor noise levels.

Explore Different Types of Thresholds
Exterior door thresholds provide essential protection from weather elements while boosting energy efficiency. Some of the best brands for door thresholds include Pemko and NGP. Here are different types of exterior door thresholds you have to know:
Saddle Thresholds
Saddle thresholds, named for their saddle-like shape, are the most commonly used thresholds in commercial buildings, particularly for exterior doors. The design of saddle thresholds is straightforward, making them versatile and the most preferred threshold for various commercial applications. It is available in both flat and half-saddle styles, and these thresholds can feature smooth or grooved surfaces, with grooved surfaces providing better slip resistance. Some saddle thresholds are available in different widths and thicknesses to accommodate varying levels of foot traffic; higher traffic areas typically require thicker and wider thresholds. These saddles are often paired with door sweeps to seal the gap between the door and the threshold, effectively keeping out external elements. Pemko 2746 Saddle Thresholds and NGP 713 Saddle Thresholds are Qualitydoor.com recommended Saddle thresholds.
Heavy Duty Stainless Steel Thresholds
Heavy-duty thresholds are built to endure heavy traffic, which comes through people and machinery such as vehicles, lawnmowers, and forklifts. These thresholds are manufactured with thicker metal and come in various types to meet diverse requirements. They are suitable for both interior and exterior openings. Pemko 154SS Thresholds and NGP 613SS Thresholds are Qualitydoor.com recommended Heavy-duty thresholds.
Panic or Latch Track Door Thresholds
Panic thresholds are designed for outswing doors and are designed to work with vertical rod panic bars. Beyond providing the standard weatherproofing features of a typical threshold, they also engage the bottom bolt of vertical rod panic hardware, removing the need for a floor-mounted strike. For proper functionality, doors must be manufactured with minimal clearance at the bottom, allowing the threshold to interact effectively with the door face and/or panic hardware. Pemko 177DT and Pemko 277DR Latching Thresholds are Qualitydoor.com recommended latching door thresholds.
Bumper Seal Vinyl Thresholds
Bumper Seal Vinyl thresholds have similar features to panic thresholds and both are designed to press against the door’s surface. These thresholds can block air and moisture effectively from entering a space. A bumper is located at the top of the threshold and makes contact with the door face when closed, creating a tight seal. Mostly the bumpers are made from materials like vinyl, pile, polypropylene, or polyurethane. When selecting a bumper threshold, it’s crucial to consider the clearance between the door and the threshold to ensure a proper seal. Pemko ADJ232V8BL Vinyl thresholds and NGP 8132 Thresholds are Qualitydoor.com recommended Bumper seal vinyl thresholds.
Thermal Break or Skid Resistant Thresholds
Thermal break or Skid-Resistant thresholds are specifically designed to minimize the impact of significant temperature differences on either side of a door. When one side experiences extreme heat or cold compared to the other, it can lead to temperature transfer across the door. Additionally, condensation may accumulate on the threshold, creating a slipping hazard. To address this, a vinyl spline is incorporated into the threshold, dividing it into two sections. This design effectively reduces temperature transfer and prevents condensation buildup. These thresholds are available in various styles. NGP 8213 thermal break thresholds and Pemko 253X3AKFG thermal break thresholds are Qualitydoor.com recommended thermal break thresholds.
Interlocking/ Offset Saddle Door Thresholds
Interlocking/Offset Saddle Door thresholds are commonly used for exterior inswing doors. The name of this threshold is derived from L or J-shaped hooks that connect the door to the threshold. This interlocking design is particularly effective for doors exposed to outdoor elements without the protection of an overhang, as it helps seal the gap between the door’s bottom and the floor. However, debris such as rocks, ice, or mud can get trapped in the hook, reducing the door’s sealing efficiency. Regular cleaning of the threshold will ensure smooth operation. Pemko 2727D and NGP 653 SIA Offset saddle thresholds are Qualitydoor.com recommended offset saddle door thresholds.
Carpet Divider Door Thresholds
Carpet divider door thresholds are used on the interior doorways to provide a smooth transition between different flooring materials. They serve to either visually separate or connect spaces in an aesthetically pleasing manner, depending on their application. Additionally, carpet dividers can play a role in fire containment by preventing flames from traveling under the door and spreading to other areas within the building. NGP 407 and NGP 398 are Qualitydoor.com recommended carpet/tile divider door thresholds.
Ramp Saddle Door Thresholds
Ramp saddle thresholds are thoughtfully designed to meet ADA (Americans with Disabilities Act) standards, ensuring smooth transitions for wheelchairs and individuals with mobility challenges. Available in durable, skid-resistant aluminum and dark bronze finishes, these thresholds are perfect for high-traffic and handicapped-accessible areas, accommodating heights of 1/4 or 1/2 inch. Sturdy rubber ramp saddles provide additional options for comfortable access, while trusted brands like Pemko and NGP National Guard ensure quality and reliability.
