So, you have a major project on your hands for making window frames. Now what? You may have worked on several other woodworking projects, but window frames have a few unique aspects to consider. No issues! We will guide you on how to get started.

Here are a few primary things to consider:


The wood should be durable. Although one side will face the inside, the other will face the outside and be exposed to the elements. So, durability is an important factor.


If you live in a region of extreme climate, you need to consider the insulating properties of the wood. Choose a wood that keeps the room cool in summer but keeps the cold out in winter.


The window frames you use should be safe to install and use. For example, frames made of wood prone to warping can cause the panes to shatter, injuring people walking below the window.


The most preferred material is wood. Nowadays, aluminum frames have gained huge popularity, but wood has a few advantages that aluminum cannot meet. For example, wood has better insulation properties and is more resistant to corrosion.
