A glazed opening in a wall, normally double-glazed in an insulated vinyl, timber or aluminium frame.

## How that compares

*Window against things of a similar time.*

- Window: 15–40 yr
- Polar bear: 20–32 yr
- Giraffe: 20–28 yr
- Grizzly bear: 20–35 yr
- Bathtub: 15–50 yr
- Elevator: 20–40 yr
- Tractor: 15–50 yr
- Sewing machine: 10–50 yr

## What that means over time

*Assuming the typical lifespan above and immediate replacement.*

| Period | How many you would buy |
| --- | --- |
| Per year | 0.04 replacements |
| Over 10 years | 1 of them |
| Over a 30-year mortgage | 1.2 of them |

> Lifespans are medians under ordinary use, not guarantees. Maintenance, how hard it is used, and build quality move individual examples a long way in both directions — which is why the range above is as wide as it is.
