Glass Seals For Your Windscreen

Glass Windscreen

Fun fact…every single car has approximately 30,000 parts, if you drive a higher end vehicle, you’re looking at maintaining closer to 40,000 parts and components. There are a lot of bits to look after, from the tiniest screws to the lifesaving sheet of glass that is your windscreen. One integral part of your vehicle that is often overlooked is your glass seals for your windscreen and windows. Keeping your seals in good health can be the difference between a safe and comfortable interior and safe and sound windscreen, or a frightening repair bill.

What is a glass seal exactly?

Windscreen and vehicle window seals are black rubber strips around the edging. They’re not only there for aesthetic reasons, they have the important job of keeping the glass firmly in place and protecting your interior from the elements. In our harsh climate, they are at risk of wearing down – particularly on older model vehicles. The rubber seals are fixed to the windscreen frame with an adhesive sealant, some of which can be more susceptible to breaking down over time than others.

Different types of glass sealants

The type of adhesive seal applied plays a pivotal role in the effectiveness and longevity of the seal. Typically windscreens are bonded with a strong adhesive glue or silicone. Because of our volatile climate, silicone is not always a sound option. As it heats and cools it expands and contracts, you don’t really want the adhesive responsible for holding your windscreen in place to be so malleable.

Similarly there are different levels of quality glue adhesives also. Cheap glues or the wrong type of adhesive can put you in serious danger. It’s important to apply an appropriate Grade A adhesive and ensure it dries properly before driving your vehicle.

What to look for when a seal is broken or wearing away

If you’re experiencing a water leak through your seals your certainly have a problem. Sometimes however, an inefficient seal is not so obvious. Look for cracks or brittle spots in the rubber. Even the smallest hairline crack can cause a leaky windscreen and lessen the integrity of this all-important lifesaving glass. You might also find areas of rust around the seals, or the bond could be peeling off in areas. Does the rubber feel like it’s loose and lifted? When you wash your car check there is no water entering the vehicle by hosing around the seals. Just apply a low water pressure rather than full force. If there’s a leak it will actually occur faster than if you’re blasting the water as it will bounce right off.

If you suspect your seals are in need of some TLC you should arrange to replace them immediately. Not only could you risk damaging your interior in a downpour, if your seals are compromised the windscreen is susceptible to cracks and other damages that can lead to a costly windscreen replacement, much more than the affordable option of repairing the seal.
