Let’s look at the main pros and cons in a bit more detail:

Pros of Aluminium Windows

Low initial cost

Compared to timber windows, aluminium window frames are much more affordable. This makes them a more feasible option for a lot of homeowners who are looking to economically improve the appearance and insulation of their homes.

No maintenance required

Aluminium windows are corrosion resistant and don’t require any maintenance. Therefore, they’re a good choice for homeowners who won’t have time to consider regular window maintenance.

Energy efficient

Aluminium windows that are fitted with thermal breaks have good energy efficiency, making them some of the most efficient frames on the market.

Cons of Aluminium Windows

Not always compatible with period homes

Some owners of period homes prefer the look of timber to aluminium. However, nowadays aluminium frames are available in a range of sympathetic designs with slim profiles that better complement traditional homes.

Less insulating than timber

Timber is naturally an extremely insulating material so aluminium still does not quite match it in terms of energy efficiency.

Pros of Timber Windows

Classic appearance

For some people who favour a traditional appearance, or have period properties, timber windows often feel like the only way to go. Of course, this is dependent on budget!

Excellent insulation

As mentioned, wood is an excellent insulator, so timber window frames provide help provide excellent insulation to the home.

Cons of Timber Windows

Timber frames are significantly more expensive than aluminium windows. Depending on how many windows need installing, timber windows could really stretch a budget to its limits.

Regular maintenance

In the first 1 – 2 years after installation, timber window frames will require retreating. They will then require regular maintenance every two years. If timber windows are left too long between treatments, they may start to rot, resulting in expensive repair and replacement fees.

Conclusion: Which is Better – Timber or Aluminium?

Aluminium windows are affordable, offer good energy efficiency and don’t require any maintenance. This makes them a straightforward choice for most homeowners who are looking to replace windows without breaking the bank.

Timber frames have their place – particularly in period properties – but thanks to advances in modern technology there are now aluminium frames that can tastefully mimic and stand in for timber frames in most instances.
