Protection Pads: An Auto glass protection technique

Protection pads for the Windshield and support kits for auto glass provide extra strength to it and ensure that it can withstand the accidental shocks and keep the thieves at bay.

In an accident, the major cuts and injuries to the occupants are caused due to the broken window glasses or the windshield. The vehicle glasses need strength to withstand the shocks and damages due to minor accidents or extreme weather conditions.
The windshield strength is important for a vehicle as it bears a lot of varying air pressures. It also needs the flexibility to withstand the elastic deformations in the body due to bumps. Additionally, the windshield should dry up quickly to allow a clear vision to the driver in the rain.

The advancement in technology and evolution of chemical methods to impart desired properties to the glass has opened up a range of innovative solutions to avoid injuries from broken glasses.

The windshields are susceptible to cracks. These cracks and chips affect the visibility and therefore compromise with the safety aspect. The repairs for glass cracks are expensive and might need full replacement. The following methods can be effective in protecting the auto glasses from cracks and chips, providing a comfortable and safe driving experience.
Glass has high compressive strength, but the flexibility and tensile strengths are relatively lower. The bending stress is mostly the reason for breaking the glass as the impact due to sudden jerk gets distributed to the car body and deforms it, but the glass has less flexibility and brakes.

Protection Pads:

Fixing the protective films can reduce the risk of glass cracks due to jerks significantly. It adds to the cost but is an effective way to incorporate a wonderful safety feature to your vehicle. The bending stress in the glass is not uniform; it’s more on the corners than the centre. Therefore, a protection pad can be used to strengthen the weak areas of the glass.

It’s basically an engineering solution made as a closed and transparent strip. It’s located on the perimeter of the windshield and has a wedge-shaped elastic and transparent outer layer while the inner layer is adhesive to hold the glass in its place.

Its working principle

The working principle of a protective pad is simple. The inner adhesive layer helps the blunt edge of the wedge-shaped profile of the paste to stick to the outer surface of the windshield along its perimeter while the sharp edge is glued to in the direction of the window centre. In the event of a sudden jerk, the thickness layer works as a cushion for the glass and because of its elastic properties saves the glass from the high bending stress. There is a further elastic elongation of the thickness layer towards the centre, this increasing stress-bearing capacity of the windshield towards the centre provides extra support and flexibility. These protective pads help in protecting the glass zones which are more susceptible to damage and hence reduce the maintenance costs for the vehicle.

Also, Protective pads, unlike Protective films, eliminate the need for the protective coating on the glass which improves the visibility and increases the durability of the protective pads.

The protective pads can be customized with different sizes and elastic capacity. Using the software programs the designing and size calculations can be performed to suit your vehicle needs perfectly.

The protective pads provide a viable solution for the Auto Glass protection and can be effective in providing more safety to the owner and his family. Professionals in the auto glass industry such as Auto Glass Changers, Canada can apply this innovative idea in a cost effective manner to ensure the best safety precautions for the customers. The protective pads are worth it as nothing is more important than safety. Installing protection pads will ensure that the probability of breaking of the glass is reduced drastically and therefore, it will save the repair costs and the precious life of the occupants.
