The sound of a stone flicking against the car’s windscreen is one that car owners dread. A small chip, left unattended, can eventually extend into cracks that split further and further across the windscreen. 

Windscreens consist of three layers: two sheets of regular glass with an inner layer of plastic (PolyVinyl Butyral – PVB) between them. This lamination layer holds the broken outer panes of glass together in the event of an accident, protecting the car’s occupants from dangerous glass shards.

Usually, when a stone or debris chips the windscreen, the damage doesn’t go through all three layers. It makes minor repairs so much easier.

Impact Damage

Driving along (or close to) newly paved roads can put the windscreen in harm’s way. Road surfaces are usually a mixture of asphalt and rock.

Contractors test broken rock for its hardness and the rocks are damaging to a windscreen—especially if high speed is involved.

The impact of these small pieces of roadside debris can create a chip and eventual crack in the windscreen. The angle and speed at which the rock hits the glass play a big role.

This kind of damage is frequently a fixable problem and typically the most common cause of all windscreen-related problems.

Stones are the most common reason for sudden chip damage to a windscreen. Trips along a freshly paved road or a lane with pebbles can cause instant ruin.

High-velocity stones can crack any of the three layers of a windscreen or even a side window.
