"Pretty good deal for $100 up front. The 5 included sensors cover my doors/sliders. We were disappointed that the mobile app functionality isn't included with the base monitoring plan after the first month. And my bathroom door sensor only works half the time. They told us that the dog (a little mini-poodle) wouldn't set off the motion sensor but she does - so we don't ever use it which leaves us exposed if someone comes in thru a window. But for basic coverage at $35 a month its not a bad deal. I like that its cellular (no land line needed) and self-installation was easy with their excellent phone app. I may upgrade the system at some point with window sensors, glass break sensor, front door camera."

Window Tinting FAQs, answered by experts

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

If your window film doesn’t come with an installation kit and its own application solution, you can make your own—but don’t use soap! Instead, use 1 teaspoon of baby shampoo mixed with a gallon of bottled water. Make sure the bucket in which you mix this solution is completely clean.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

The costs range from $5 to $15 per square foot, depending on the film type, UV protection level, and labor.

Window security film has a few key benefits that make it an enticing home improvement:

  • It’s much more affordable than shatterproof windows or hurricane windows.

  • It improves your home’s energy efficiency and can save money on heating and cooling bills.

  • It makes it harder to break into your home.

  • It helps prevent dangerous shattered glass after an impact.

  • You can tint it to provide additional protection from the sunlight.
