1. Household Objects to the Rescue!

Many common household objects can be quite useful when it comes to silently breaking any type of glass, not just windows. By combining them, you’ll get an almost perfect way of soundproofing your work.

Take a look at this combination of duct tape, a thick blanket, and a large pillow.

First, you need to cover the window with duct tape, and make sure you leave not a single square inch uncovered, and do that from both sides if possible to maximize the effect.

Secondly, find a nice, thick blanket, and place in under the window. If you don’t have a blanket you can use for this, a couple of layers of cardboard or cartons will do just fine.

You can use a common blanket, or, ideally, one or two of those special soundproofing blankets.

Finally, get the pillow – the denser the better – and place it against the glass, then gently start tapping it with a hammer.

This way, the noise caused by shattering glass is almost eliminated – the pillow absorbs the brunt of it, the tape keeps the glass from falling down, and if there are some glass shards that end up not sticking to the tape, the blankets are there to absorb the noise of them falling down.

2. Use a Sparkplug

A sparkplug is a useful little thing. It’s made to deliver electricity to your car engine’s combustion chamber, but it can be used for another purpose – breaking the glass.

Believe it or not, this little fella is super-effective when it comes to breaking glass quietly! In fact, it’s much quieter than your safety hammer!

The outer part of your window glass cools much more rapidly than the inner part, and the tension arising from different temperatures is what enables this little piece of ceramic to penetrate the glass quietly and easily.

And to maximize effectiveness, don’t hit the center of the glass – hit the corners!

3. Break the Windows with Porcelain Bits

Standard porcelain bits used in drills can also come handy when in a pinch. You can either throw them at the glass or use them to hit the glass from up close.

Much like the spark plug part, they’re more silent than a hammer, and thus much more effective.

Additionally, they’re also commonly found in every tool shed or a toolbox, so that’s also a big plus.

4. Hit It with a Hammer!

The safety hammer is a versatile tool every car owner should have. You can use it in many extreme situations, but you can also use it when it comes to breaking window glass.

It is relatively quiet when applied correctly – remember, you should tap the edges and corners of your window glass – and however inelegant compared to some other tools mentioned in this text, and its effectiveness is certainly undeniable.

However, in some methods we previously described, you don’t necessarily need the safety hammer – any hammer will work just fine as long as it’s not too big.

5. Use an EMT Device

EMT device is a device used by professionals. They’re used mostly for breaking car windows, but you can also use it to break standard windows equally well.

The device on its own barely produces any sound other than the sound of dropping shards of glass, but that can easily be avoided by using blankets.

If you can’t get one, a standard hammer and apiece of nail work just as good.

6. Use the Automated Steel Center Punch Tool

Among carpenters and plumbers, an automated punch tool is extremely popular when it comes to breaking the glass and removing window panes.

It’s fairly easy to use. Press it against the glass, release the spring, and the tool breaks the glass with ease, and more importantly – without too big of a noise.

If you’re a handyman, you likely already have the punch tool, and if not, you can get it here.

Necessary Safety Measures

And there you go!

These pieces of advice will be of great help when it comes to soundproofing your glass-breaking activities. However, before you start the silent smashing, here are some safety measures you should pay attention to, just in case.

Protection is the Key!

Shattered glass is a great source of danger for everyone, so before you start breaking it make sure you’re properly protected.

Protective clothing is mandatory. Long-sleeved jackets and safety goggles are a great way of protecting yourself from unsuspected glass shards, and a pair of gloves will prevent all possible cuts.

Wearing protective boots is also a great idea, and if don’t have them, any good pair of shoes should do. 

Check which Type of Glass You’re Breaking

Different windows can be fitted with different types of glass, so make sure you know which type of glass your windows have.

For example, safety glass is a type of glass with two glass layers and a plastic layer in between them, and because of it, it breaks much more quietly than your standard window glass.

Keep the Children and the Pets Away!

Finally, make sure your pets and children aren’t nearby when you start breaking the glass.

The last thing you want is for them to get hurt because of the random shard of glass you failed to pick up after all the shattering is done!
