Windshield replacing during winter season

A windscreen replacement London is always a good idea whenever you notice a crack or chip on your windshield. However, timing is crucial especially during winter. If it’s too cold, the glass will be prone to cracking.

The reason why it’s not advisable to replace car glass when it’s too cold is because the old and new auto glass has different levels of thermal expansion rates. The old glass has been exposed to the same temperatures for a long period of time and therefore it has expanded to match the temperature. The new glass on the other hand, has not yet expanded or contracted to match the temperature and therefore it expands at a different rate compared with the old glass.

This causes windscreen stress which in turn leads to cracks and chips that may occur almost immediately after installation or even after several weeks later when temperatures change abruptly.

Auto Glass Express technicians can easily fix this issue using special denatured alcohol that makes sure that the two glasses expand at the same rate during installation. The installation will also be done carefully to make sure that no stress is created between the old and new glasses.
