What does it mean when a double glazed window is sealed?
The construction of the sealed doubled glazed unit means there should be a constant pressure inside the vacuum. Any changes to the internal pressure can put the glass under strain, but in most eventualities, it will be robust enough to withstand the variance. If it isn’t, then that’s when cracks will begin to appear.
Can double glazing break in Rugby?
But heat strength isn’t the factor that can break glass, but how and where it is targeted. The morning sun in the UK rises in the south, so in the winter months, south-facing double glazing in Rugby is more susceptible to cracks. As the chilled glass meets the more temperate sunlight, the centre of the pane can warm much quicker than the corners, placing strain on the glass. If this strain proves too much, the glass can break.

How does double glazing work?
Double glazing is ultimately constructed by placing two sheets of glass either side of a vacuum, or in most cases a layer of inert gas. This helps to create an invisible barrier which helps to contain heat hence keeping drafts out of your home, the temperature stable, and your energy bills down.
What determines which windows are most at risk of breaking?
The size and shape of your window can determine which ones are most at risk of breaking. Thinking about it in terms of aspect ratio, if you have a small square or even a circular shaped window, you will find that these are typically at very low risk of suffering a break.
