The Necessity of a Window Seal for Air Conditioner on Crank Out Windows

As someone who has lived in multiple apartments with crank out windows and has used portable air conditioners, I can attest to the importance of having a window seal specifically designed for these types of windows. Without it, the functionality and effectiveness of the air conditioner can be greatly diminished.

Firstly, crank out windows open horizontally instead of vertically like traditional sliding windows. This means that there is a gap along the bottom edge of the window when fully opened. Without a proper seal, cool air from the air conditioner will escape through this gap, making it difficult to maintain a desired temperature in the room.

Moreover, crank out windows often have a crank handle that protrudes from the window frame. This can create an uneven surface for traditional window seals, causing gaps and air leaks. A window seal specifically designed for crank out windows will have cutouts or adjustable sections to accommodate this handle and create a tight seal.

In addition to keeping cool air in, a window seal for crank out windows also helps keep hot air and insects out. This is especially important during the hot summer months when bugs are more prevalent and can easily enter through any small openings around the window.

My Buying Guides on ‘Window Seal For Air Conditioner On Crank Out Windoes’

As someone who has recently installed an air conditioner on a crank out window, I understand the importance of finding the right window seal to ensure proper installation and efficiency. After researching and going through trial and error, I have put together this buying guide to help others in their search for a suitable window seal for an air conditioner on crank out windows.

Understanding the Need for a Window Seal

Before diving into the different types of window seals available, it is important to understand why a window seal is necessary for an air conditioner on crank out windows. Unlike sliding windows, crank out windows have a gap between the sash and the frame when fully closed. This gap can cause air leakage, making it difficult for the air conditioner to cool the room effectively. A window seal acts as a barrier to prevent this air leakage and also helps in keeping insects and debris out.

Type of Window Seals

There are three main types of window seals that are suitable for crank out windows:

1. Foam Seals: These are adhesive foam strips that can be easily cut to fit the length of your window frame. Foam seals are affordable and easy to install, making them a popular choice among homeowners.

2. Vinyl Seals: Vinyl seals are made of durable vinyl material and come with self-adhesive backing for easy installation. They provide better insulation compared to foam seals but may be more expensive.

3. Fabric Seals: Fabric seals consist of a fabric cover filled with insulating material such as polyurethane foam or polyester fiberfill. They offer superior insulation but may require professional installation, making them the most expensive option.

Considerations When Buying Window Seals

When choosing a window seal for your air conditioner on crank out windows, there are a few factors you should keep in mind:

1. Size: It is important to measure your window frame accurately before purchasing a window seal. Make sure you choose one that fits snugly without any gaps or overlaps.

2. Compatibility: Some window seals may not be suitable for certain types of crank out windows or air conditioners. Be sure to check with the manufacturer or read reviews from other customers before making a purchase.

3. Material: The material of the window seal should be able to withstand outdoor elements such as rain and sunlight without deteriorating quickly.

4. Energy Efficiency: Look for window seals with higher R-values as they provide better insulation, helping you save on energy costs in the long run.

5. Noise Reduction: If noise is an issue in your area, consider getting a fabric seal as it provides better noise reduction compared to foam or vinyl seals.

Installation Tips

Installing a window seal may seem like an intimidating task, but with these tips, it can be done easily:

1. Clean the surface of your window frame before installing the seal, making sure there is no dirt or debris that could affect its adhesion.

2. Start from one corner and slowly apply pressure along the length of your chosen seal until it reaches the other corner.
