Is discovering an answer to how the cracks on the windscreen of your Volvo V40 appeared getting you down?

Are you questioning how exactly this occurred? 

How can I stop it from recurring again? 

Where do I go to get this fixed?

Damn, why is this so expensive?

In this section, I’ll be going over all the details that lead to your Volvo V40’s windscreen needing a repair/replacement and then what your next course of action needs to be to take care of the car glass that makes up this vehicle.

Why is the Volvo V40 a popular car?

It’s obvious to see why your V40 is among Volvo’s best-selling model cars in the UK. It’s one of the most affordable types, and it also fits well within one of the most valuable segments: the small family hatch class. 

On appearances alone, it’s a rather foxy-looking Volvo, and even the hood has been kept low and sporty thanks to the extra extension of a pedestrian-side airbag. There’s a refined version of the earlier models underneath the chassis, and a range of engines show an even higher level of efficiency. With these points, there’s no doubting the potential it holds within its incredible little frame.

The V40 is economical, fashionable, made from high-quality materials, and offers fantastic value – an overall champion formula.

What is the car glass of a Volvo V40 made from?

We create your Volvo V40’s car glass from two classes of glass; laminated and tempered.

Your forward-type windscreen is constructed with laminated glass, and every single other section of car glass (such as all the side windows and your rear windscreen) we manufacture with tempered glass. 

But why is this? Is this choice important at all?

Laminated Glass

This glass is hardier and more enduring than its tempered equivalent. You make it by fusing two (or more in some cases) sheets of ordinary glass with one synthetic interlayer in-between- usually a vinyl substitute. 

These layers are compressed with incredible strength levels and then exposed to intense heat to bond them together and produce a long-lasting glass variant that can process massive pressure levels before cracking.

We construct windscreens from this type of glass to restrict the quantity of glass shards that could come from an accident and fly towards the driver and any riders. We can also fix laminated glass if a trivial amount of damage occurs, which brings about an enormous sigh of relief, considering how highly expensive windscreen replacements can amount to.

Tempered Glass

This class of glass is the more brittle equivalent (while still being more sturdy than your standard/annealed glass). Tempered glass is created by bestowing a transparent sheet of glass to (again) incredibly high heat levels within a sizeable oven-like structure, to levels exceeding 600 degrees celsius even! 

This glass sheet then undergoes a coolant procedure known as quenching; it is pressurised and cooled very rapidly with water. This procedure results in your tempered glass, which will split into small and relatively safe pieces when destroyed, unlike regular panes of glass. 

Due to the nature of tempered glass, we use it in situations where human safety might be more risky, such as the side and rear windows in your Volvo V40. 

We cannot repair this glass variant, though. So, we need to replace it completely every single time it is damaged.

Why do cracks and chips appear on the windscreen of my Volvo V40?

We’ve all been there – enjoying a casual driving down the road, appreciating the virtue of the day when – WHAM!

You spot it – that treacherous tiny crack or chip that is suddenly marring your perfect view. 

Where did this bugger come from? 

Well, here are a few factors you can assign the blame to:

Small pebbles and rocks from the road

You’ve reasonably heard or even felt this phenomenon happen before, particularly when driving along nearby roads that have just been freshly paved or had a recent pothole fixed… and when you’ve been a wayward driver yourself and didn’t leave enough of a length between yourself and the vehicle in front of you.

The force damage from these miniature and tiresome pieces of roadside debris can create a crack in your windscreen if it flies in from the wrong angle and with just enough force. This is a small problem but typically the most typical cause of any and all windscreen-related grievances.

When it gets too hot and too cold

What a complete joy it is to encounter both sides of the spectrum in terms of weather in the UK, right? Icy winds and heated sunlight mean that our poor Volvo V40 is ever-so-slightly contracting and expanding its framework due to the fluctuating shifts in temperature.

This phenomenon produces something called a stress fracture, which is an on-point name since the windscreen and its driver both crack from the tension in this case. 

So whenever you have what seems to be a totally random crack appear abruptly for no reason at all – it’s truly from all the fluctuating temperatures your Volvo V40 has experienced.

Weather patterns

As discussed before, hot and cold temperatures from the climate can lead to cracks, such as ice appearing on a windscreen, or having the sun beat down its rays all day on the framework of your Volvo V40.

Storm type debris, such as hailstones or wind-flung tree branches, are also a couple of cumulative culprits who keep on adding damage to your car. 

Poorly done framework and sub-par car glass repairs/instalments

Whenever you deliver your automobile to an inadequately trained car glass technician who used worn-out tools and non-OEM compliant materials, you’re bound to find further problems not too far down the line.

Car glass parts can grind badly on each other, creating other types of stress fractures from the framework not fitting well with the windscreen, which can suddenly shatter windscreens.

Car crashes

This cause is the pinnacle fear of everyone driving on the street, a non-stop impact course with another car or person/animal crossing the street. 

Best case scenario? It’s only a minor fender bender that expects an insurance exchange.

At its worst? It’s a write-off of your precious Volvo V40.

Even a medium-sized car collision can lead to you needing to replace complete divisions of car glass and all the relevant and interconnecting parts that come with these types of replacements.

What can I do to prevent further cracks from appearing on the windscreen of my Volvo V40?

So, we’ve gone over all the principal reasons that your Volvo V40 windscreen might abruptly develop issues with its surfaces. But what are some preventative measures we can put in place to restrict or entirely block these problems from ever rearing their ugly heads?

Provide proper shelter

Hot sunlight, chilling winds, storm-flung debris and everyday objects turned projectile; these are all matters that you can block from interacting with your car by ensuring that you have it parked under cover when you aren’t driving it the road somewhere safely, away from the outside elements.

Do not attempt to remove ice from your windscreen through boiling water

This de-thawing “method” is an expeditious way to get your windscreen to crack or even shatter very suddenly. Remember how we explained fluctuations in shifting extreme temperatures could create stress fractures? Well, there’s no subtle fluctuation here; its whiplash for your poor Volvo V40.

I repeat: Do. Not. Do. This.

Keep your Volvo V40’s windscreen clean

Leaving dust and dirty water on the windscreen of your vehicle seems like a normal thing to do; after all, isn’t that why it’s there in the first place? 

But leaving it dirty for long can allow for corrosion to occur, along with undermining the structural integrity of any existing cracks or chips. It’s always best to wash your windscreen frequently, especially if excess mud or dirt has been exposed to your car for any number of reasons.

Pay attention to your surroundings 

When accidents occur, it is often found that it could have easily been avoided if the guilty party had just paid more attention while driving. 

Never text-and-drive on the road, always make sure to leave a decent amount of space between yourself and the vehicle in front of you, and always drive like everyone on the street is an idiot actively trying to kill you. 

This way, we all get a greater opportunity to make it home alive and unharmed, as well as keeping a crack and dent free windscreen!

Get your windscreen examined and repaired by professional car glass technicians

It’s natural to sometimes go with the most affordable option when locating a place to repair or replace your windscreen and other parts of car glass. 

Unfortunately, going to these cheap institutions might end up costing you more in the long run due to inadequately installed car glass and the shoddy materials used.

What windscreen features does my Volvo V40 have?

The Volvo V40 has some amazingly beneficial features that can help with your everyday driving. The following are the ones that interact directly with the Volvo’s windscreen itself, which will impact costs due to the use of more sophisticated tools and replacing more equipment within the replacement.

Here are the chief ones that necessitate you to know about them before calling a car glass professional to perform your windscreen replacement successfully.

Rain sensor

A rain sensor is found behind the windscreen itself, as well as behind the rearview mirror. It activates its function when any rainfall or noticeable amounts of liquid comes into contact with the windscreen. 

It will begin the windscreen wipers movement automatically, thus assisting the driver with any water-type distortions within their field of vision produced by the falling rain.

Green tint on your windscreen

If you check your windscreen closely, you might notice it’s possibly tinted a slightly greenish-blue colour. If you direct your gaze near the top end, you’ll find the tint to be more pronounced. 

This tint is there to block all sun rays from damaging your eyes or opposing your vision while driving (especially during the hours of sunrise and sunset).

A noise reduction windscreen

An acoustic windscreen includes an extra sheet of a vinyl element between the glass layers that were used to create your windscreen. This layer has soundproofing properties that hinder the outside worlds noise levels, providing you with more comfort and a sense of peace.

Camera on windscreen

A camera on your windscreen is in position to assist the driver with parking problems and rearview perception. It can also collect footage for the scene of a car accident and thus present proof that you were not liable.

Heated windscreen

We get an electrically heated windscreen when we triple-glaze the glass, which allows them to discharge electronically-controlled radiant heat along the windscreen’s surface safely. 

This system provides you with a magnified heated luxury to facilitate cosy car rides. It also supports the structural problems caused by erosion from the cold and any visibility problems associated with frost crystallisation or blizzards that could damage your Volvo V40’s windscreen.

Interesting Factoid about the Volvo brand!

Two ways that the Volvo resonates so strongly with its Swedish roots.

1. Volvo was established in a Stockholm eatery named “Sturehof” on 25 July 1924 by two men, Assar Gabrielsson and Gustav Larsson. But where did they make “Volvo” then? “Volvere” is the infinitive construction of the verb “roll” in Latin. In its first person singular form, the verb “volvere” changes over to “volvo,” i.e. “I roll.” And they have been rolling into our hearts and on our streets ever since!

2. The Volvo emblem of a shield and a spear is also a representation of Mars – god of war in Roman mythology – which originates from the chemical figure for iron – a circle with an arrow pointing diagonally upwards to the right. The slanting iron bar they attach the logo to the first Volvo models’ grilles also went on to become part of the standard logo. The iron badge represents the Swedish iron industry and its qualities of power and endurance.
