While most people think the only modern option for windows these days is uPVC, there is actually another contender. Now that the technology around them has improved, aluminium windows are becoming the first choice of many homeowners.
There are plenty of reasons why aluminium windows are on the up, but there are also reasons why you may want to choose a different window frame material. Read on to find out about both the pros and cons of aluminium windows.
Pros
Low maintenance
Aluminium frames are low maintenance. They don’t need treating with anything and the most you’ll have to do is wipe them with a damp cloth.
Durable
One of the biggest benefits to aluminium windows is that they’re durable. Modern-day aluminium frames won’t rust, warp or corrode in harsh weather conditions. Aluminium is also lightweight and very strong.
Long-lasting
Aluminium windows are long-lasting. If they’re manufactured and installed correctly, you won’t have to worry about replacing your windows more than once in your lifetime.
Flexible
Aluminium is flexible. This makes them perfect for properties with unusually shaped openings as they can be moulded to the exact shape and size you require.
Versatile

Cons
Not always energy efficient
Aluminium windows aren’t always energy efficient. Good quality frames are good insulators and shouldn’t let the heat out of your house. But poor quality or old-fashioned aluminium frames can conduct heat and increase your bills.
Expensive
Aluminium frames can be expensive. They certainly cost quite a bit more than uPVC frames, so if you’re on a budget aluminium frames may not be the best choice.
So aluminium window frames have both pros and cons. However, there are so many benefits to aluminium windows that they should be an option when you’re thinking about replacing your double glazing.
