Aluminium windows

Aluminium frames provide more strength and durability to your windows while requiring less maintenance. Compared to other types, aluminium is also easy to recycle and sustainable, making it a highly reliable material even after decades of use.

Wooden windows

Wooden windows add a warm, homey and laid-back feel to your living space. Like aluminium, it is also a highly sustainable option, although it could get expensive. One important thing to consider when getting a window made from wood is maintenance, as it is prone to rot, especially when exposed to insects. You would also need occasional varnishes and repainting.

Despite this, some still prefer wooden frames as these serve as an excellent room insulator and can easily pull off that classic and elegant finish. 

Composite windows

Composite windows are a combination of various materials like wood, aluminium, and polymer plastics. With this flexible design, you’ll be able to achieve the advantages highlighted in each material while avoiding the cons. However, you might need to prepare more budget as composite windows are often the most expensive option across all window materials.
