How Do Aluminium Windows Compare With PVC Windows?

You need to gather as much information as possible about different window types so that you can choose what material is the best for your needs. This article compares two common types of windows (aluminium windows and PVC windows). Use this information to make an informed decision regarding the suitability of any of these types of windows for your needs.


PVC windows tend to have large frames. That large profile may affect the aesthetic appeal of the windows. This is because the large frames may reduce the space available to fit window glass so that light can be allowed into the home. Aluminium windows have smaller frames that give a home a streamlined appearance. These smaller frames make the windows more visually appealing.


PVC windows are more susceptible to damage by the elements. For instance, the UV rays from the sun can cause the windows to fade quickly. Prolonged exposure of PVC windows to the elements may also cause them to warp. This can compel you to replace the windows sooner than you would have wished. Alumimium windows are less likely to be damaged by the elements. This is because the metal is not easily damaged by wind, sunlight or rain.


Both types of windows require minimal maintenance. Regular cleaning to remove the dirt and grime that builds up on windows is sufficient to keep the windows looking as good as new. However, you may need to be careful when choosing cleaning chemicals so that the selected cleaning chemicals don't damage the PVC windows.

Initial Cost

Aluminium windows are likely to be more expensive than PVC windows. This is because aluminium is generally expensive as a raw material when compared to plastic. However, the longevity of aluminium windows may justify that high initial cost because those windows may still be in use long after the PVC windows have reached the end of their service life.

Thermal Insulation

PVC windows may do a better job of insulating your home. This is because plastic is a poor conductor of heat. Aluminium has a high thermal conductivity so more heat may be able to pass through the aluminium window frames. However, thermal breaks are built into the aluminium windows in order to increase their ability to insulate your home.

As you can see, each type of window has its strengths and drawbacks. It is therefore up to you to compare their different attributes so that you choose the type that will be better at addressing your needs.
