What can I use to temporarily cover my car window?

If you need to temporarily cover a broken or damaged car window, there are a few options you can use until you are able to get the window properly repaired or replaced.

Plastic Sheeting

One of the most common temporary solutions for a damaged car window is to use thick plastic sheeting. Here are some tips for using plastic sheeting:

• Use heavy duty plastic that is at least 6 mil thick – regular plastic bags or drop cloths may easily rip.
• Cut the plastic a few inches larger than your window frame.
• Clean the window frame thoroughly so the plastic adheres well.
• Apply duct tape around the edges to hold the plastic in place.
• Attach the tape to the body of the car, not the window itself.
• Make sure the plastic is pulled tightly across the window to minimize fluttering.

Plastic sheeting can protect the interior of your car from weather and debris until you can get the window replaced. Just be aware that it may appear wavy or wrinkled when driving.

Plexiglass

Plexiglass (acrylic glass) is a great rigid and durable material to temporarily patch a damaged car window. Here are some tips for using plexiglass:

• Measure the size you need and purchase a plexiglass sheet at least 1/8-inch thick.
• Use fine-toothed jigsaw or bandsaw to cut the plexiglass to size.
• Drill holes through the plexiglass and car window frame so you can bolt it in place.
• Use rubber washers and waterproof silicone to seal the edges.
• If needed, cut notches so it fits around window controls or mirrors.

Plexiglass is easy to install and provides a waterproof seal. Just be careful of the edges which can be sharp. It also may be prone to scratching over time.

Plywood

For a quick, inexpensive fix, plywood can also work to cover a damaged car window temporarily. Here are some tips for using plywood:

• Use at least 1/4-inch thick exterior grade plywood.
• Measure and cut to size using a jigsaw or handsaw.
• Paint or stain the wood to protect it from the elements.
• Attach boards across the window using screws or bolts if possible.
• Seal the edges with silicone caulk or weatherstripping tape.

Plywood is readily available and durable. Just keep in mind that it may split over time. Also be sure to smooth any rough edges to prevent injury.

Window Wrap Film

Window wrap film is a heavy duty adhesive film made specifically for covering windows. Here are some benefits of using window wrap film:

• Creates a tight seal around damaged glass.
• Available in clear or tinted blackout options.
• Can block UV rays to prevent interior fading.
• Self-adhesive for quick, simple application.
• Can provide security by making window opaque.
• Some types are shatterproof for added safety.

Window wrap film can provide an attractive temporary solution. Just be sure to measure properly and clean the window thoroughly before application. Leaving bubbles or creases can affect visibility.

Cardboard

For a very simple temporary window patch, you can use cardboard sealed with tape. Here are some cardboard tips:

• Use thick corrugated cardboard for best support.
• Cut cardboard to overlap window frame by several inches.
• Cover exterior side with heavy duty tape or contact paper.
• Tape around all edges to seal out moisture.
• Replace frequently as cardboard degrades.

Cardboard is not a long-term solution, but works in a pinch. It tends to degrade quickly so replace it frequently if using for more than a couple days.

Automotive Replacement Window

For the best semi-permanent solution, consider purchasing an replacement window made specifically for automotive applications. Here are some benefits:

• Designed to precisely fit your car make and model.
• Manufactured from tempered glass or acrylic.
• Mounts using pre-applied adhesive or mechanical fasteners.
• Matches the look of OEM glass.
• Provides good insulation and UV protection.
• Allows full use of mechanical windows.

Aftermarket windows can be more expensive but provide a high quality repair that can last for years. They are relatively easy for auto glass shops to install properly.

Additional Tips

When temporarily covering a damaged car window, here are some additional tips to keep in mind:

• Completely clean and dry the window area before applying any covering.
• Measure the window frame accurately to get a tight, secure fit.
• Use mechanical fasteners like screws or bolts if possible for added security.
• Seal all edges thoroughly with tape, caulk or weatherstripping.
• Make sure coverings are pulled tightly to minimize wind flutter.
• Inspect coverings frequently and reapply tape or seals if needed.
• Avoid using makeshift solutions like garbage bags that can easily rip.
• Don’t apply anything with permanent adhesive to avoid damaging paint or glass.

Taking the time to properly install a temporary window cover will help keep the inside of your car protected from the elements until you can get a window repair. Go with a durable material that blocks wind and debris while still allowing some visibility. Carefully measure and seal the edges to prevent moisture damage or wind noise while driving.

Conclusion

Damaged car windows should be repaired or replaced as soon as possible for safety and vehicle integrity. However, temporary solutions like plastic sheeting, plexiglass, plywood or window wrap film can seal and protect the window opening until a proper repair is done. Choose a material that is durable, seals tightly, and allows for adequate visibility. With the right temporary window patch, you can keep driving safely while avoiding further interior damage from weather and debris until your window is permanently restored.
