Weatherstripping (doors), locking that nasty draft out!
There are typically two distinct areas of a door where different types of weatherstripping may be used to provide optimal sealing and insulation: The top and sides (jambs) and the bottom (threshold). Door manufacturers incorporate many different types and configurations (overlapping types) of door weatherstripping. Our post covers some of the more common ones.
Door Threshold:
Weatherstripping devices that are installed on the bottom edge of a door (sweeps) are designed to seal the gap between the door and the floor, preventing drafts, insects, dust, and other unwanted elements from entering a home. Various types of weatherstripping can be applied to the door threshold to create a tight seal along the bottom of the door. Door threshold weatherstripping includes:
- Bottom sweeps
- U-shaped door sweeps
- Automatic door sweeps
- Slide-on door sweeps
- Brush sweeps
- Triple-fin door sweeps
- Adjustable door sweeps
- Interlocking door sweeps
- Door shoe sweeps
- Soundproof door sweeps
- Rain drip door sweeps
Door Jambs:
Weatherstripping for door jambs is primarily focused on sealing the gaps between the door and the door frame when the door is closed. Various types of weatherstripping can be applied to the door jamb to create a tight seal along the sides and top of the door. Door jamb weatherstripping includes:
- Compression seal weatherstripping
- V-strip weatherstripping
- Bulb seal weatherstripping
- Magnetic weatherstripping
- Interlocking metal weatherstripping
- Brush-type weatherstripping
- Pile weatherstripping
DOOR THRESHOLD weatherstripping types:
1. Bottom sweeps
Exterior door bottom sweeps, also known as door sweeps or weatherstripping, are devices installed at the bottom of exterior doors to create a seal against drafts, moisture, dust, insects, and noise. They are typically made of materials like rubber, vinyl, or bristle brushes. Here are some pros and cons of using exterior door bottom sweeps:
Pros:
- Reduces heating and cooling costs by preventing air leakage
- Minimizes drafts and maintains a more comfortable indoor temperature
- Blocks external sounds, creating a quieter environment
- Acts as a barrier against insects and pests
- Blocks dust and debris from entering your home
Cons:
- May require tools and basic DIY skills
- May require periodic replacement or maintenance
- Not all door sweeps may be suitable for all door types or floor surfaces
- Some door sweeps may be visible and affect the appearance of the door
2. U-shaped door sweeps
A U-shaped sweep is a type of weatherstripping that is attached to the bottom of the door. It is typically made of flexible materials such as rubber or vinyl. The U-shaped sweep is designed to be screwed or nailed onto the bottom edge of the door, forming a seal against the threshold. When the door is closed, the U-shaped sweep compresses against the threshold, creating a barrier against drafts, insects, and moisture. U-shaped sweeps can include and combine several other styles of sweeps including brush, rain drips, shoe, and bottom sweeps, and are typically made of vinyl or rubber.
Pros:
- Forms a tight seal at the bottom of the door, reducing drafts and preventing moisture, dust, and insects from entering
- Improves energy efficiency by minimizing air leakage and reducing heating and cooling costs
- Generally simple to install with basic tools and instructions
- Designed to withstand regular use and weather exposure
Cons:
- U-shaped door sweeps may not be suitable for all types of doors or floor surfaces
- The U-shaped design can affect clearance for doors that open over thick carpeting or uneven floors
- The visible U-shaped profile may not be visually appealing to some individuals
- Over time, the door sweep may wear out and require replacement for continued effectiveness
3. Automatic door sweeps
Automatic door sweeps, also known as automatic door bottoms, are a type of door sweep that operates automatically when the door is closed. They have a mechanism that lowers a seal or brush to the floor as the door closes, creating a tight seal.
Pros:
- Provides excellent sealing capabilities, minimizing drafts, noise, dust, and insects from entering
- Improve energy efficiency by reducing air leakage and lowering heating and cooling costs
- Operates automatically when the door is closed, eliminating the need for manual adjustments
- Can be adjusted to accommodate uneven floors or carpets for a better seal
- Often designed to be discreet and unobtrusive, preserving the overall appearance of the door
Cons:
- More expensive than manual door sweeps
- Requires more installation expertise and precision compared to manual sweeps
- May require occasional maintenance or adjustment to ensure proper functionality
- Some automatic door sweeps may require a power source (battery or electrical) for the automatic operation,
4. Slide-on door sweeps
A slide-on sweep, also referred to as a snap-in sweep or door bottom seal, is another type of weatherstripping used for the bottom of exterior doors. It consists of a rigid or semi-rigid strip with a flexible sealing component, often made of vinyl or rubber. Unlike the u-shaped sweep, the slide-on sweep is not attached with screws or nails. Instead, it is designed to be easily installed by sliding the sweep onto the bottom edge of the door. The flexible sealing component of the slide-on sweep creates a tight seal against the threshold when the door is closed, providing protection against drafts, insects, and outside elements.
Pros:
- Easy to install without the need for tools or complicated adjustments
- They can be used on a variety of door types and sizes
- Generally affordable and offer a budget-friendly option for improving insulation and sealing

10. Acoustic door sweeps
Acoustic door sweeps can be effective in reducing sound transmission through the gap between a door and the floor. They create a seal to prevent sound leakage and improve soundproofing. However, their effectiveness may vary depending on factors like the quality of the door sweep and the level of sound you want to block. While door sweeps can help, they are often more effective when used in conjunction with other soundproofing techniques such as sealing gaps, adding curtains or vinyl, and improving room insulation. A holistic approach to soundproofing is generally recommended for optimal results. Acoustic door sweeps are typically available as aftermarket add-on products.
Pros:
- Effectively minimize the transmission of noise, creating a quieter indoor environment
- By reducing sound transfer, they provide increased privacy, making it harder for conversations or other noises to be heard from outside the room
- Provide a good seal against drafts and air leakage, which can contribute to improved energy efficiency and lower energy costs
- They are generally simple to install with basic tools and instructions
Cons:
- May be more expensive than standard door sweeps due to their specialized design and materials
- While they excel at noise reduction, soundproof door sweeps may not provide the same level of sealing against drafts, insects, dust, or moisture as other types of door sweeps
- The visible presence of a soundproof door sweep may affect the appearance of the door, and some options may not be as visually appealing as standard door sweeps
11. Rain drip door sweeps
Also known as rain deflectors, rain guards or rain drip caps, are a type of door sweep designed to divert water away from the door and threshold area. They typically feature a sloped or angled design to prevent rainwater from entering. Rain drip caps are often incorporated into various types of sweeps.

- The visible presence of a rain drip door sweep may affect the appearance of the door, and some options may not be as visually appealing as standard door sweeps
- Rain drip door sweeps primarily address water diversion and may not offer significant energy efficiency or noise reduction benefits
Pre-installed vs retrofit door weatherstripping solutions
Weatherstripping is seamlessly incorporated into the manufacturing process of new doors to ensure effective sealing and insulation right from the start of the window's life cycle. Retrofit weatherstripping solutions can be installed as additional or replacement weatherproofing measures to address gaps and air leakage in older structures. Check with the manufacturer for parts to ensure a perfect fit.
