Double glazing is tough to break, as everyone knows. Installed into homes to seal out drafts and make homes more secure, durable and should last for years. Double glazing acts as a shock absorber because the air between the glass sheets is pressurized, so heavy things can be thrown at the window and bounce back. Despite this, it is still possible to crack double-glazed windows by accident, and we certainly do not recommend throwing anything at your windows! Although things go wrong from time to time, there are a few common ways people ruin double glazing.
Are double-glazed windows hard to break?
This is the number one problem people have with windows. A glass cutter’s most important job was replacing it since glass broke so quickly. New windows are so hard to break that windows companies aren’t often asked to replace broken glass anymore.
There’s no way you could break double-glazed windows unless you tried. The first thing is the glass structure, which isn’t as simple as it used to be. It’s now toughened so the glass will stand up to shocks, children throwing footballs, the weather, and break-ins. A double-glazed window is hard to break without making a lot of noise.
Would it be easier to break a single-glazed window?
When an object, such as a football hits a single pane of glass, the force of the impact bends the glass beyond its elastic limit, causing it to break. Deformation of the pane caused by the ball can cause the higher air pressure in a double-glazed window. High pressure makes it hard to break windows because it opposes deformation. That only works if the double glazing unit is reasonably airtight.) The second pane resists high pressures because football impact forces are spread out over the whole window area. Broken double-glazed windows aren’t hard to break: tap them hard enough with a hard object, preferably near a corner. As a result of toughened glass, thousands of tiny fragments will break away from the pane.
