Accidently Damage From Lawn Mowers – Take Prevention this Summer
Bear in mind how fast a stone is flung after contact with a mower blade and even though all of these large glass units are toughened, the stone will still shatter the outer pane of glass. It is very rare for one to go through both.
If mowing in the proximity of a patio door, French door or conservatory, placing a large sheet of old cardboard in between you and the glass will stop this from happening. Even a roll of old stair carpet placed across the lower part of the glass unit will normally work. Always better to be safe than sorry as these large toughened double glazed units are by no means cheap!
