Everything about window types and their benefits

Here we go through what you should consider when buying windows and how you can make a choice that both improves comfort and reduces energy consumption in your home.

1. Choice of material: Wood, Aluminum or PVC?

Window frames come in different materials, each with their pros and cons:

• Wooden windows give a classic and natural feeling. They have good insulating properties, but require regular maintenance such as painting and oiling.
• Aluminum windows are extremely durable and require minimal maintenance. However, they have poorer insulating properties if they are not additionally insulated with, for example, a thermal break.
• PVC windows are a popular and affordable option. They have good insulation, are maintenance-free, and have a long service life.

2. Glass selection: Single glass, Double glass or Triple glass

One of the most important decisions when choosing windows is what type of glass you will have. Windows with multiple layers of glass improve energy efficiency:

• Single glazing is rarely a good option in the Nordic climate as it emits a lot of heat.
• Double glazing offers a good balance between price and energy efficiency and is standard in most homes.
• Triple glazing provides the best insulation and is ideal for energy efficient houses or areas with cold climates.

3. Energy saving and U-value

The window's U-value indicates how well it insulates. The lower the U-value, the better the window is at retaining heat and keeping energy costs down. For an average home in Sweden, a U-value between 1.0 and 1.2 is recommended to maximize energy savings.

4. Design and Functionality

In addition to insulation and energy efficiency, windows should also suit the architectural style of your house. Choose between classic slatted windows, modern panoramic windows, or traditional wooden windows depending on the design of the house. You should also consider opening mechanisms, such as:

• Fixed window, which cannot be opened and gives a cleaner look.
• Pivot window, which can be opened inwards or outwards depending on the need.
• Kip window, which offers ventilation without opening the entire window.

5. Maintenance and Long-Term Cost

Consider how much maintenance you are willing to do over time. Some windows, like wood, need regular care, while others like aluminum or PVC can get by with minimal care. Investing in high-quality windows with the right insulation can reduce maintenance and energy costs in the long term.

6. Sound insulation

If you live in a noisy area or near a busy road, soundproof windows can be a wise investment. These windows have thicker glass or more layers of glass that effectively block sound.

Conclusion

Choosing the right window means balancing aesthetics, functionality and energy efficiency. A well-thought-out choice can improve both the comfort of your home and help lower energy costs.
