Alien Seal is a type of rubber weather stripping that helps insulate leaky windows, doors, and showers. It works on both indoor and outdoor surfaces, and it can keep cool air from escaping an air-conditioned home. The seal is completely fastener-free and peels and sticks anywhere the user needs it. Its rubber material can be easily measured and cut with scissors to fit any size door or window. Alien Seal's transparency helps it blend into different-colored surfaces.

  • Flexible, Transparent Rubber

    Alien Seal is made from flexible, see-through rubber. This makes it more design-friendly than other rubber seals, which often come in gray, brown, and beige. The transparent rubber blends into any surface or material. Its flexibility makes it easy to cut and mold to any door or window - both indoors and outdoors.

  • Peel-and-Stick Backing

    Alien Seal comes with a peel-and-stick adhesive backing. This makes for a simple application in any area of the user's house. The adhesive is strong and can stick to multiple materials, including wood, glass, tile, and metal.

  • Weatherproof Design

    This seal is designed to withstand the elements. It can be used outdoors on leaking windows or doors. The adhesive withstands wind and precipitation, and it keeps its seal for an extended period of time.

  • Multipurpose Uses

    The seal is waterproof, so it can be used as both a weather seal and a shower seal. It keeps water from spilling out of the shower onto the floor or from soaking into tile grout.

  • Works Immediately

    After the customer applies Alien Seal, there is no delay before it begins to work. The seal traps air inside the house immediately so that residents can stay cool all day.

How to Use (Step by Step)

  1. Measure and Mark

    It's important to measure and mark your weather seal roll before beginning to use it. Measure so that the seal will fit the door or window where it's needed. Mark the ends with a permanent marker or another type of ink that works well on rubber.

  2. Cut the Seal

    Carefully trim the seal along the marked lines. Alien Seal cuts easily with scissors or a utility blade, so you don't need to purchase or use any special tools.

  3. Peel and Stick

    Once the seal is cut and ready to go, you can peel off the adhesive backing and stick it to your door or window. Make sure to lay down the seal carefully so that it's flat. Placing the seal at an angle may create gaps for unwanted airflow. For the seal to work properly, it needs to be flush against the door or window.

  4. Test it Out!

    After the seal is successfully applied, it's time to test it. Allow your air conditioning to run for a bit in your house as you normally would. Stand by the door or window every so often to see whether the cold air is escaping (or if unwanted hot air is coming inside).

  5. *In the Shower

    Follow instructions 1 and 2, then peel and stick your Alien Seal to the faulty gap in your shower. To test it, you'll need to run the water in your shower and see if it continues to leak.

How It Works

Weather seal works by covering gaps left by faulty doors and windows. It's designed to stop air from leaving your house while also keeping air from coming in. The overall goal is to maintain a constant temperature in your home and stay comfortable throughout the seasons.

A similar type of seal works to keep showers from leaking onto bathroom floors. With Alien Seal, customers can use the same seal for both types of projects.

Positive Aspects

  • No Need for Two Seals

    Alien Seal works as weather stripping and as a shower seal, so customers don't have to invest in two separate products. This saves money, time, and storage space.

  • Quick and Easy Application

    Alien Seal is faster and easier to use than traditional weather seals, which require the user to slot the seal between the door and the floor or doorframe. This cuts down work time and labor for the homeowner.

  • Sticky Backing

    Some types of traditional weather seal need to fit inside a specific door groove or gap. The seal's peel-and-stick backing allows the homeowner to simply stick the seal on the outside of the door without worrying above sizing or fit.

  • 30-Day Grace Period

    The company offers a 30-Day money back offer for new customers. Buyers can try the product for 30 days. If they're not satisfied with the seal's performance, they can return it for a full refund.

Negative Aspects

  • Some Features Unclear

    It's not clear from the product description whether the seal traps both cool and warm air. The demonstrations show it keeping a house cool, but a customer would want to know whether it works the same way in the winter. There is no information about this feature on the website.

  • Visibility

    Though the seal is transparent, it's still visible on surfaces, especially darker wood doors or windows. Unlike traditional seals, it doesn't hide between the edge of the door and the floor or doorframe.

  • Not Sold in Stores

    The seal is only sold online and not in stores. This could be inconvenient for a homeowner who needs to fix a seal quickly. They might prefer to stop by their local hardware store instead of waiting several days for the seal to ship.

  • Does it Stick to Everything?

    The seal is advertised to stick to wood and glass, but it's not clear whether it sticks to other outdoor materials like brick, stone, or concrete. This would be important information to know for outdoor applications.

  • No Info on Length

    The company doesn't advertise how much seal comes in a roll. This makes it impossible to compare to competitor products, most of whom offer their own product sizes in addition to a price-per-foot ratio. Though the company advertises a three-for-one deal, it's impossible to know how much seal the customer is actually receiving for the price.

Critical Advice

This item could be either a benefit or a drawback, depending on the needs of a customer. Before purchasing Alien Seal, customers should think about whether they're okay with 1) seal's visibility and 2) not knowing how long the roll is. This product could be very valuable for customers who have to do a lot of sealing quickly, or customers who need both weather stripping and shower sealant. The most advantageous aspect of the product is its flexibility. Customers who need to use the seal for multiple purposes will be pleased with its ease of use and multifaceted design.
