Somethings can only be dealt with by those who have some knowledge in the domain and this is also the case with things such as plumbing, joinery and so on. In fact, all those specialized domains require some research and some specialized knowledge, which makes them out of reach for a lot of people. This is also why many people don't know about the advantages and disadvantages of the different types of joinery systems, for instance.
When it comes to the aluminum systems, here are a few of the advantages they present. First of all, they help you with cutting the expenses for heat and emission of toxic substances. These systems also provide very good sound and thermal insulation. There are certain people who can benefit from these joinery systems more than others, these persons being those allergic to different things.
There are a lot of profile colours and shapes on the market and it is also good to know that once you get such a system, you no longer have to wrap your mind around painting expenses. However, these joinery systems are more expensive than the PVC ones and the difference is quite a significant one.
On the other hand, you can go for wood joinery systems, these having a special design and being flexible in terms of shapes and sizes. Also, the thermal insulation is very good with them and you can obtain a lot of colour combinations. They are very resistant and natural, but they need to be well executed, otherwise, they can suffer deformations in time.
Of course, there are a lot more things you could find out about these things, but you need to do some further research.
