The usefulness of sealing a window for a portable air conditioner

In this regard, good thermal insulation must be done for better comfort inside the room. Hence the usefulness of sealing.

Sealing a window for a monobloc portable air conditioner allows you to :

• Facilitate the expulsion of hot air ;
• Reduce the loss of cool air ;
• Avoid drilling a wall hole ;
• Limit energy overconsumption ;
• Keep the interior of your house clean : insects, dust, and dirt will be expelled from your room thanks to the device.

A window sealing is recommended for opening or closing your window without needing to dismantle it often.

Solutions to seal a window for a portable air conditioner

Equip yourself with a window sealing tool

For any job, it is essential to have the necessary materials for sealing your window.

The roll of adhesive tape

This accessory is equipped with a mechanical fastening system consisting of one part with tiny textile loops and another part with hooks. With this set, you can easily lock or unlock it. A weather-resistant tape should be preferred to ensure the durability of your window’s sealing system.Before purchasing, take into account the dimensions of your window.

The airtight tarp with a zipper

This device must be installed in the gap of the window to ensure good airflow to the outside of your home. This prevents the cool air from escaping the room and the outside air from entering. This window sealing device for portable air conditioners ensures better insulation of the room. Models with a hook-and-loop fastening system are recommended. Additionally, a waterproof and washable product is ideal and should be preferred. Moreover, before making a choice, measure the width of your window carefully.

Perform a complete cleaning of the window

Materials must be placed on clean surfaces for more effective window sealing. To do this, follow these steps :

• Using a soft cloth or a vacuum, remove the dust present on the window.

• If there are deposits and oils, clean them with a mineral spirit suitable for the material of your window.

• Gently scrape off the paint from the window ;

• Wipe with a soapy cloth using a cleaning product suitable for your room’s window and let it dry for a few minutes.

If a sealing has already been performed on your window, you will need a screwdriver, a tear, and a knife to remove the sealant and proceed with the previously mentioned cleaning steps.

Install the adhesive tape

For its installation at the window, you must first open it. Then you need to measure the dimensions of the sash. This is done in width and height. With these measurements, cut the required length of the adhesive tape. Finally, stick this tape according to the appropriate size for optimal sealing of your window.

Set up the sealing tarp

The location of the exhaust hose of the mobile air conditioner must be made in the zipper. This is not exactly in the center of the sealing tarp. It should be known that one side, which you need to place at the level of the opening sash, must be narrower than the other. Then, you must place the fixed part of the tarp on :

• The closed sash if your windows are double-opening ;
• The frame if you have a window with a single opening.

Subsequently, the alignment of the tapes must be followed. All that remains is to attach the movable part of the tarp to the open sash.

Fix the exhaust hose

To do this, you must :

• Place the portable air conditioner near the window ;
• Open the zipper of the tarp and place the exhaust hose in it ;
• Close the zipper ;
• With a cable tie, secure the hose.
