What to Consider When Buying Draft Stoppers?
What is your purpose in using a stopper under the door? Are you blocking the air and smells? Or are you using it to block the crawlies and rats? Your purpose decides what kind of products you will need.
Best materials for exterior door draft stoppers
Draft stoppers made of silicone or vinyl are most suitable for exterior doors. They are weatherproof, can resist humidity and sunlight exposure. If your threshold gets wet frequently, a silicone or vinyl draft stopper will be the best option. There are adhesive behind the strip, therefore, when you are installing a silicone stopper to the door, heating the adhesive can ensure tight installation. They slide better on smooth floors, which prevents them from tearing. They work well on blocking air, and bugs. The thick solid color models can reduce some light, but have weak effects on noise.
Best materials for interior door draft stoppers
Draft stoppers with foam fillings and fabric covering are a good option for interior doors. They are lightweight and can cover any gap under doors and windows. Because they are not able to hold their own weight, they must be attached to your door using magnets, clips, or other materials. The dual-side models which can block air from both inside and outside, don’t need an attachment to install.
Some stoppers have durable fabric coverings, such as linen or plush, which can withstand frequent abrasion on the floor.
Many draft stoppers make use of plastic beads and crushed rocks, which have a significant weight and can hole the stoppers in place. These beads are usually combined with other materials and are heavier than foam. They are less likely to break and shift in strong winds. They can also block crawlies and rats to some extent.
It is important to measure your door before you shop for draft stoppers. Every gap height between the floor and door is different. Most are between 3-inch to 5-inch. The standard exterior door measures 36 inches in width. However, yours might be larger or smaller.
A stopper should be the right size for your door. You will have draft gaps where warm air can escape if the draft stopper you choose is too small. It may not fit flush against your door if it is too long. It may not be able to attach with magnets or clips if it is too long. This could negate the purpose of purchasing this handy feature.
You can cut some draft stoppers to your specifications. This is a great feature for homes with doors that are not standard or where you need extra space.
Modern draft stoppers have two styles: single-strip and double-sided. Because single-strip draft stoppers are not able to hold their own weight in wind, they must be attached to your door using magnets, clips, adhesive, or other materials. This will also enable the draft stopper to follow the door opening and closing. Therefore, there is no need to manually move the stoppers each time you enter or leave the room.
Draft stoppers can also be double-sided. They are made of two tubes that sandwich your doors in the middle. If the central portion of your door fits correctly, this design can provide twice the protection. However, the connecting between fabric and the door must be not too high and too low. Too high, it can leave gaps. Too low and it could drag on the floor, become stuck beneath.
Double-sided draft stoppers work well on covered porches or apartment buildings where the front door opens into an unheated hallway. A double-sided leather stopper can be used to prevent your front door from being exposed to snow, dirt, and ice.
There are many solid colors and adorable designs for draft stoppers. You can choose one to match with your door, or a contrast color to create a fresh view. There are also some adorable animal plush draft stoppers, which are great options for bedrooms or kids’ rooms. If the draft stopper is for exterior doors, it’s better to choose a water-resistant or easy-to-wash draft stopper, because they can be stained by dirt and water.
How Much Do Draft Stoppers Cost?
You can expect to buy draft stoppers between $8 to $40. Cheap draft stoppers likely have thin foam interiors and polyester exteriors. They might not stick to your door well and may get stuck under the door. The covering fabric tears easily after a period of use.
High-end draft stoppers may be made with silicone, vinyl, or solid fabric, and filled with thick foam, beads, or stone. They may have a double-sided or single-strip design, even some adorable animal designs. They can be attached magnetically to your door with secure clips or hook-and-loop closures.

Are Draft Stoppers Machine-washable?
