Broken Window With Security Window Film

What Is Security Window Film? 

Window film is a thin strong piece of transparent plastic.

One that’s designed to adhere to the inside of your windows.

We all know if you hit a window with a baseball bat it will shatter.

And will leave a gaping hole.

Making it easy to blast out the remaining shards.

But security window film holds ALL these shards together.

This prevents a fast forced entry AND flying shards of glass.

Turning a 5-second forced entry into a minutes delay (or longer).

THAT may not seem like much of a delay…

But here’s the thing, burglars take the path of least resistance.

Every second delay can mean the difference between getting loot or getting caught.

Even a few seconds is a significant deterrent!

The bottom line is:

Security window film makes your home much harder to enter.

Thus, safer.

3 Reasons For Installing Security Window Film

One of the most overlooked home fortification upgrades is securing your windows.

But home fortification doesn’t just mean protection against forced entry.

There’s also another crucial reason to invest in security window film.

So, let’s go over both now.

1. Prevent Break-ins And Forced Entry

Of course, preventing forced entry is the most obvious “reason,” and it’s a good one!

Windows are one of the most vulnerable entry points in any home.

Why? Because professional burglars are not stupid.

They know doors have alarm systems and are often reinforced.

And THAT’s why they target windows.

A burglar can break an unprotected window in mere seconds.

  • Quietly using tools like a window punch to shatter the glass.
  • Or blasting the window out using a hammer or baseball bat.

And once a window’s glass is gone, it’s easy to slip into and back out of a home undetected.

Especially ground access windows in backyards of homes.

Want some proof?

Watch this video to see the power of installing window security film on your home:

↓ Safety Window Film Forced Entry Education

This isn’t rocket science.

Your unprotected windows are vulnerable to burglars.

2. Safety From Flying Shattered Glass Shards

Glass is fragile.

Anyone with kids learning how to hit a baseball knows this.

Any hard object (bat, ball, rock, etc.) can break a windowpane.

And what happens when it breaks?

It shatters into chunks of razor-sharp shards.

These shards are extremely dangerous to anyone nearby.

Especially during:

  • inclement weather
  • a natural disaster
  • or even a bomb blast

For example:

High winds from a hurricane or tornado can easily break windowpanes.

The shattered glass creates flying shard bullets.

These glass shards can cause serious injuries and even death…

Earthquakes can blow out windows and rain down knife-like shards on anyone below.

And a bomb blast can blow glass shards inward into unsuspecting occupants.

Bomb blast shards can even cause permanent blindness.

The bottom line is:

Adding security window film is a massive home fortification upgrade.

And even more important, at a fair price without sacrificing aesthetics.

3. Better Looking Than Window Security Bars

Burglar bars might provide even MORE window security but at a cost.

They look like a prison.

If you want security without the bars, window security film is the answer.

Best Locations To Install Window Security Film 

If you can afford the investment, add security film to ALL your home’s windows.

This is especially true for small homes with only a handful of windows.

But what if you have a larger home with many windows?

Well, then, focus on the MOST vulnerable windows first.

Ok, but which ones are those?

Ground Access Windows

For break-in prevention, it’s any window someone can access from the ground unassisted.

These are the windows that don’t need a ladder to access.

Thus, making them more susceptible to burglar entry.

This goes double for any windows in hidden locations (usually behind a house).

These are locations someone could enter undetected, away from public view.

Install security film on these FIRST.

Bedroom Windows

Now let’s look at it from a safety standpoint.

You should add security film to all bedroom windows.

Especially those apart of a small child’s bedroom.

You don’t want shards to fly toward anyone sleeping during a storm, earthquake, or bomb blast…

Roof Access Windows

Next would be any windows with roof access.

Some homes have dormer-type windows or unique rooflines.

If a burglar can get on a roof and access the windows, add security window film on those.

All remaining windows are a lower priority.

But if you want ultimate security, do them all.

Best Window Security Film Features To Look For 

First up is the film thickness.

There are different thickness options.

They come in 100 micrometers (or 4 mils) through 525 micrometers (or 21 mils).

The film thickness affects the level of protection.

The thicker the film, the more window strength and protection they afford.

As a rule of thumb, manufacturers recommend a 100-micrometer for glass up to 3mm thick (or 1/8 inch).

And 175 micrometers for glass over 6mm thick (or ¼ inch).

And while thickness is important, there are a few other aspects to consider, such as:

  • Adhesive bond strength of the film
  • Quality of the application
  • Window structure and frame construction

Some Alternative Window Security Options

You have several options for window security.

But window security film is the best in my opinion.

But you shouldn’t just take my word for it.

But it’s important to understand ALL your options before investing.

1. Burglar Bars

From a pure break-in deterrent standpoint, you can’t beat burglar bars.

These bad boys will not only keep a burglar out but prevent them from even trying.

This is called target hardening.

They see the bars and immediately decide it’s more lucrative to move to easier targets.

But few people think burglar bars look good.

Functionally, burglar bars are great but aesthetically in the dumps.

And most people prefer NOT to look out through a set of bars.

It’s too similar to looking out a jail cell.

Plus, burglar bars don’t prevent dangerous shards during high winds or explosions.

2.  Riot Glass

Riot glass is amazing if you’re willing to spend A LOT of money.

This makes sense for places such as storefronts, especially stores with valuables inside.

This type of glass is an upgrade to prevent quick smash-and-grab jobs…

But these are best for commercial applications and “overkill” for most homes.

↓ Regular Glass Vs. Riot Glass

3. Security Screens

This option might be appealing to homeowners.

Instead of adding a transparent film to your windows, you upgrade your window screens.

These are newer and more proprietary options.

But are not an easy DIY project option…

Plus, I tend to worry about quick egress with these screens.

How easy and quick are they to remove in a fire?

I haven’t found a great answer to this question yet.

But feel free to investigate if these seem a solution for YOU.

4. Upgraded Window Locks / Alarms Sensors

Some people add security lock upgrades and alarm sensors to all their home windows.

Sometimes these are in addition to and sometimes instead of security window film.

And these can be helpful but not worth it.

Upgraded locks don’t provide as much security as people think.

Why? Because preventing a window from sliding open is useless if a burglar can break out the glass.

A wise burglar will break the window and lay a thick cloth over the shards.

This allows them to safely slip into the home with ease.

NO need to slide the window open at all…

But if a burglar can’t shatter the glass in the first place, they can’t gain entry or access to even the most basic window locks!

So, after considering alternatives, I believe window security film is the best home fortification option.

Not only do they provide protection from break-ins, but they’re also transparent.

When installed properly, you can’t even tell they’re on your windows.

With security film – the burglar will quickly realize,

“This is not an ordinary window.”

They will likely shatter it, realize it has security film, and get the hell out of there FAST.

There’s no way they’ll risk all the noise.

Someone might wake up to a single crash sound but quickly drift back to sleep after a few minutes.

But quick and quiet entry is NOT possible with window security film.

A delay of anywhere from 20 seconds to over a few minutes AND preventing the quiet break-ins…

How To Install Security Window Film

Like any DIY project, if you take your time and do it right, you can do it as well as any professional.

But if you rush the job, you can screw it up big time.

Here are a few videos showing you how to install security window film properly.

Watch them all and you’ll have the knowledge you need to tackle this project:

↓ Installing Security Film

↓ Window Security Film Installation Guide

Note: IF possible, try to secure the film across the window AND to the frame as well.

Otherwise, someone can bust out the entire window from its frame.

Sure, installing it that way won’t be as easy.

But by securing the film to the glass AND frame, you’re making it a stronger.

Try finding a strong bonding agent or caulk bead to run a bead along the frame.

Final Thoughts

Too many people only focus on their home alarm systems and motion lights.

But if you want true home fortification and security you MUST protect your windows.

Windows are the most vulnerable entry points people forget to protect.

Don’t be like most people…

Do yourself and your family a favor and protect them with security window film.

Otherwise, you may end up wishing you had a “do-over.”

But there are no “do-overs” in home security.

You either make it a priority today or wish did later…
