Replacement Sash Windows London | What Are The Different Material Choices?

As you may know, sash windows are a timeless English classic that are still extremely popular in areas such as London. It can get very overwhelming researching the different material options for your new windows.

In general, wood or aluminium clad wood are the best for replacement sash windows as they are the closest to replicating authentic profiling and proportions used in traditional times. The main benefit of uPVC is a cheap price but this often comes at a cost of thicker frames and poor quality.

The different types of sash windows available in the UK include Timber, Aluminium Clad Wood (Aluclad) or uPVC.
