| Yes these have been around for centuries and for good reason, they add character to the home. | Older wooden frames need constant maintenance since they are more likely to swell in hot humid conditions and shrink in cold weather. | Great strength and will resist the strongest of winds. | If outdoor temperature is extreme, the frame temperature will reflect the outdoor temperature. | Longer life than wooden frames. | May crack if temperature is extremely low. In most instances they don't crack. |
| Provides excellent thermal performance by keeping the heat from passing through. | Older wooden frames are difficult to open or close since due to warping and swelling. | Least expensive of all the storm window frames and easy to install. | | More pliable than aluminum and much more so than wood. | Colour tends to fade with age. |
| Modern wooden frames last a lot longer than older wooden frames | Shorter lifespan than both vinyl and aluminum frames | Does not wear down as quickly as wooden frames. Doesn't corrode like steel. | | Can be used in custom storm windows. Can be matched to nearly any colour you desire. | If the outside temperature is extremely high, the vinyl can become stretched. |
| Modern timber has been treated with chemicals to reduce the progression of rot and mold. | Should be painted and sealed every 4 years to slow down the ageing process. | Aluminum frames are resistant to scratching | | Not damaged by flooding unlike wooden frames. | |
| You can reduce maintenance time by asking for clad windows instead. | | Requires very little maintenance. | | They are installed on the outside and perform well against wind, rain, sunlight and heat. | |
| Clad wood windows are made by placing a thin strip of either aluminum or vinyl over the front of the wooden frame. | | You can obtain thermally improved aluminum frames. These provide better insulation while maintaining the strength and pliability of aluminum. | | Vinyl is nearly maintenance free just like aluminum and clad wood windows. | |
| | | | Can be strengthened by incorporating metal reinforcements to the hollow chambers that are within the vinyl. | |
