What is a casement window?

The casement window is presented as a standard window with a total opening of its glass towards the house’s interior, which facilitates 100% ventilation of the spaces. But in addition, it has an airtight closing that provides security to the homes and perfect thermal and acoustic insulation.

Casement windows features

Some of the main characteristics of casement windows are:

  • Full opening: these windows allow them to be opened entirely without limit or effort.
  • Hermetic closing: by design, these windows have an airtight seal so that neither the heat in winter nor the coolness of the house in summer can escape.
  • Materials: this type of window has a greater variety of materials. They can be made of PVC, aluminum, steel, or wood.

Casement windows benefits

Using this type of window provides a series of advantages, such as the following:

What material is best for your casement window frame?

The primary materials for your casement window are the following:

Aluminum frame

It comes in various formats, and its maintenance is practically null. In addition, it resists the passage of time very well because it does not rust, and its weight/resistance ratio is excellent, so it is very suitable for large windows.

Wooden frame

Aesthetically it is usually the favorite. There are many types of wood, each with its specific properties, but as a general rule, it is a resistant material, relatively heavy. It does not transmit heat well, so placing this type of frame is an excellent way to save energy. Its disadvantage is that it usually requires continuous maintenance.

Vinyl frames

They do not require painting, and modern advances minimize cracking, warping, and discoloration. With essential maintenance, vinyl frames are very durable.

They also offer superior thermal protection compared to wood or aluminum windows and are recyclable, making them a very environmentally friendly window option.
