Aluminium vs. Timber for Doors and Windows

Aluminium is a highly durable and extremely abundant material that offers a fantastic wealth of advantages as a building material. First used in the 1920s for finishing roofs and for use in drains and wall panels, aluminium is widely used for a variety of practical and decorative purposes. This includes window and door frames, staircases, air conditioning systems, solar protection, heating systems, furniture and much more. 

When it comes to windows and doors, aluminium offers a host of benefits that make it superior to traditional alternatives like PVC or timber. From its strength to environmental friendliness, below we look at the benefits of choosing aluminium over timber. 

Maintenance and Durability 

Due to its high strength as well as its rust and corrosion resistant properties, aluminium windows and doors are extremely durable and virtually maintenance free. You will not find a material that is more weather resistant under harsh conditions. Timber windows and doors are much more likely to swell, split, warp or crack over time from rain, wind and sun. Aluminium is approximately four times stronger by comparison. 


Of the two options, aluminium is more affordable than timber. Aluminium is also extremely reliable along with being economical. The real savings with aluminium windows and doors are in the upkeep. They pretty much don’t require any repairs or maintenance for decades unlike timber, which is more prone to damage and will likely need to be replaced within ten to fifteen years. 

Design Flexibility 

When it comes to customisation, there’s no better choice. The flexibility of aluminium means it can be shaped in a variety of ways without affecting its strength so there are very few limitations when it comes to application and design. Timber on the other hand is limited by the type of shapes you can create using joined panels. Larger frames are more prone to warping and twisting, especially when exposed to harsh weather. 

Aluminium can be left in its finished condition or it can be anodised, or powder coated for additional protection. Powder coating allows you to finish your windows and doors in a wide range of colours, so you can achieve the exact look you want to suit your style or match the rest of your property. Anodising is an electrochemical metal surface preparation process that improves durability. 

Environmental Footprint 

Timber is not a very eco-friendly option. It isn’t the worst choice, but it pales in comparison to aluminium, which can be endlessly recycled. Timber requires trees to be felled in order to produce it. Meanwhile aluminium lasts a decade and when it’s no longer needed, it only requires five per cent of the initial energy used to produce it to recycle and refabricate it into a new product.
