Sunblocker On Bedroom Windows: A Good Idea?

Sunlight streaming through bedroom windows can be a nuisance, especially if you want a lie-in or need to keep your room cool. There are many ways to block out the sun, from temporary fixes such as blankets and cardboard, to more permanent solutions like installing shutters or tinted window film. One option you may not have considered is using a windshield sunblocker, designed to attach to a car's windshield or side window to keep the sun out and reduce the temperature inside. But can you put a windshield sunblocker on your bedroom window?

How do windshield sunblockers work?

Windshield sun shades, also known as sun shields, are protective shields attached to a car's windshield or side window to prevent sunlight from reaching the interior and reduce the temperature inside the car. They are typically made of a layer of mylar or aluminium foil, which reflects sunlight away from the car's interior. Some windshield sun shades also have a reflective surface to bounce light away without it entering the car, reducing the interior temperature.

The first known sun-shade patent was filed in 1911 by Frank H. Ilse of Chicago. In 1970, the Israeli businessman Avraham Levy invented an accordion-like cardboard sun blocker, which he claimed to have sold 1 million of in Israel since the mid-1970s.

Windshield sun shades are designed to fit the inside of a car's front windshield, side windows, or back window. They are usually attached to the window using suction cups or static electricity. Some variants also have additional fastening elements such as hooks, clasps, buckles, or magnets that attach to the car frame or shade.

Sun shades are particularly useful in environments with strong and direct sunshine, and their usage is often seasonal and tied to the weather. They can help decrease the inside temperature of parked cars, protect passengers from direct UV rays, and prevent damage to items left in the car, such as electronic devices.

In addition to their practical benefits, sun shades can also provide a sense of privacy by blocking out outside light during the day or at night.

Are there different types of windshield sunblockers?

Yes, there are different types of windshield sunblockers. These include:

• Windshield sunshades: These are designed to fit specific vehicle types, such as small cars, SUVs, and sedans. They are typically made of reflective, metallic, or polyester material and can be folded for easy storage. Some have elastic straps that attach to the side mirrors, while others have security panels to hold them in place.
• Sunshade umbrellas: These are spring-structured umbrellas that can be placed inside the car, covering the windshield and blocking sun rays and heat damage.
• Sunshade films: These are tinted window films that can be applied to windows to reduce sunlight while still allowing some visibility.
• Car window shades: These are designed for side windows and usually come in packs of 2 or 4. They can be made of mesh or other materials and are often used to protect children, pets, or breastfeeding mothers from the sun's glare and UV rays.
• Sunshade curtains: These are curtains designed to block out sunlight and UV rays. They are typically made of thick, dark-colored materials like cotton or polyester and can be hung using a curtain rod.
• Awnings: These are installed above the window, jutting out to cover the top of the window and prevent the sun from coming in while still allowing a view.
• Shutters: These can be interior or exterior and come in various styles, such as Bahama and Sarasota. They can be raised and lowered to cover the entire window and are available in different materials like wood, steel, aluminum, and vinyl.

Can I make my own bedroom window sunblocker?

Yes, you can make your own bedroom window sunblocker. There are several options for blocking sunlight from coming through your windows, ranging from temporary to permanent solutions.

One of the cheapest and easiest ways to block out sunlight is to use blankets or sheets. The darker and thicker the material, the better it will block out the sun. To hang the sheet or blanket, you can use strong tape such as duct tape, or tacks. This option may not be the most aesthetically pleasing, but it is a simple and effective temporary solution.

Another option is to use aluminium foil, which can be taped to the window with the shiny side facing out. This will completely block your view, but it is also an inexpensive and efficient way to block sunlight and reduce cooling costs.

If you are looking for a more tailored solution, you can invest in blackout curtains or blinds, which are designed to block out light and UV rays. These can be purchased at most homeware or curtain stores, or online.

For a more permanent solution, you can install tinted window film, which can be cut to size and applied directly to the window. This option will reduce sunlight while still allowing you to see out of the window.

Additionally, you can make your own window screens, which can be a cost-effective way to partially block sunlight. Window screens also allow you to keep your windows open without letting bugs or debris inside.

Finally, you can mount shutters or awnings to the exterior or interior of your windows. These come in a variety of styles and price points and can be purchased at most home improvement stores or online. Shutters and awnings can also help to reduce your heating and cooling costs.

What are the benefits of using a sunblocker?

Using a sunblocker can be beneficial in several ways. Firstly, it can help you get a good night's sleep by blocking out early morning sunlight. During the day, a sunblocker can reduce your air conditioning bills by preventing the sun from heating up your room. Additionally, blocking the sun can protect your furniture and carpeting from fading due to prolonged exposure to sunlight.

Sunblockers can also make it easier for you to view television and computer screens clearly by reducing glare and excess brightness. They can also provide privacy and insulation, helping to lower your heating and cooling costs.

There are various options for sunblockers, from temporary fixes like cardboard or aluminium foil to more permanent solutions such as curtains, blinds, shutters, awnings, and tinted window films. Each option offers a different level of sun-blocking effectiveness, visual appeal, and ease of installation.

Overall, using a sunblocker can improve your comfort, protect your belongings, and potentially save you money on energy costs.

Are there alternatives to a sunblocker?

There are several alternatives to a windshield sunblocker for your bedroom window. Here are some options:

Blackout Curtains

Blackout curtains are a popular choice for blocking sunlight from entering a room. They are designed to block out light and ultraviolet (UV) rays, which can fade your furnishings and increase your air conditioning bills. They come in a variety of patterns and designs and can be purchased at most stores that sell curtains. When properly installed, blackout curtains can also help reduce your heating and cooling bills by up to 20%.

Aluminum Foil

Covering your windows with aluminum foil is another inexpensive and easy way to block out the sun. This method will completely block your view and may not be visually appealing, but it will effectively reflect the sun's rays and lower your cooling bills.

Shutters and Awnings

Exterior shutters or shades are recommended by the Florida Solar Energy Center, especially for windows that receive a lot of sunlight throughout the day. Various styles, such as Bahama and Sarasota shutters, offer different looks and price points while effectively blocking the sun. Awnings are another option, installed above the window to block the sun without obstructing your view.

Window Film

Applying tinted window film is a great option if you want to reduce sunlight while still being able to see out the window. Window film can be purchased online or at most home improvement stores and is easy to install. It typically requires measuring, cutting to size, and adhering to the glass with the help of a hairdryer.

Frosted Spray Paint

Similar to window film, frosting your windows with spray paint allows you to block some sunlight while maintaining a level of privacy. This method is cost-effective and easy to apply, requiring only tape to protect the window frame and a thin coat of spray paint.

Blinds

Installing vinyl, PV, aluminum, or wood blinds is an effective and relatively inexpensive way to block sunlight. Cordless fabric blinds tend to be more effective at blocking light than vinyl blinds, and blackout blinds are also available for complete sun blockage.
