Understanding Window Frame Materials: A Comprehensive Guide

Home window repairs can be a daunting task. In addition to the labour, it turns out there are a lot of different options for the windows and the materials they’re made from. How do you choose which one is best for you?

Let’s take a look at the various types of window frames you can choose from.  



Wood is a timeless look that adds class and style to any window frame. Wood windows are energy efficient and can last a long time if they are maintained properly. However, they are a more expensive option. 



  • A timeless look that never goes out of style 

  • Can last over 50 years when well-maintained 

  • Can change out the look by painting or staining the wood 

  • Energy-efficient 



  • Need to be refinished every 5-10 years 

  • Can rot, mould, or deteriorate due to poor maintenance 

  • Expensive 



Vinyl windows are the most affordable option for window frames. This also makes them the most popular choice for window replacement. Vinyl is composed of PVC mixed with additives and pigments to form a modern window frame that is fade-resistant and maintenance-free. 



  • Affordable 

  • Maintenance-free 

  • Energy-efficient 

  • Fade-resistant 

  • Comes in many colours, styles, and types  



  • Aesthetics, and bulkier frames, may not go well with wooden or historic homes 

  • Cannot be paint painted 

  • Varying quality among brands 



Aluminum is a durable and lightweight option for window replacements. These frames are also very low maintenance. However, they are not very energy efficient. Many modern models will feature a thermal break that improves energy efficiency.   



  • Low-maintenance (just clean the frames a few times per year) 

  • Strong and lightweight 

  • Thermally improved designs 

  • Comes in many colours 

  • Features a lower-profile, modern frame 



  • Can rust if not properly maintained 

  • May not be as energy efficient as other options 



Fibreglass is the most energy-efficient option for window replacement. It is also the strongest and most durable. Fibreglass consists of glass fibres mixed with resin and other additives, resulting in a strong, energy-efficient frame. However, it is not as widely available, so you might be out of luck.  



  • Low maintenance 

  • Moisture-resistant and weather-resistant 

  • High energy efficiency 

  • Can come in a thinner frame 

  • One of the strongest frame materials 



  • Limited colour and design options 

  • Harder to find
