Plastic or aluminum windows: which is better for your home?

27.06.2025

How to choose between plastic and aluminum windows? This is a common question that does not have a clear answer. Both types of windows have their advantages and can be a great choice for your home or office, but each of them has its own characteristics. Let's figure out which one is right for you.

Plastic windows

Plastic windows are the most common choice for residential premises, due to their good thermal insulation and affordable price. Their advantages:

1. Thermal insulation. Plastic windows provide excellent thermal insulation, which helps reduce heating costs. This is due to the multi-chamber profile design, which prevents heat leakage.
2. Sound insulation. Plastic windows also offer good sound insulation, especially if you live in a noisy area. Multi-chamber glass units significantly reduce street noise.
3. Cost. Plastic windows are usually cheaper than aluminum ones. This can be an important factor when choosing windows, especially for people on a budget.
4. Care and maintenance. Plastic windows are easier to care for. They do not need to be regularly painted or treated like aluminum ones.

Aluminum windows

Aluminum windows are a more expensive and premium option. Their distinctive features:

1. Resistance to external influences. Aluminum is not subject to corrosion, and windows made of it serve for a long time, retaining their appearance. This makes aluminum windows ideal for use in areas with high humidity or in coastal areas.
2. Thin and stylish frames. Aluminum windows have thinner frames, which allows for a larger glass surface area. This makes such windows an excellent choice for those who value the maximum amount of light in the room.
3. Aesthetics and modern design. Aluminum windows look more modern and can be made in a variety of colors and coatings, which allows them to fit perfectly into any interior.
4. Durability. Aluminum is very strong and durable. These windows can withstand strong temperature changes and can last for decades.

What to choose?

If heat and sound insulation, as well as reasonable cost, are important to you, then plastic windows are the best choice. However, if you prefer stylish design, minimalist frames and high durability, aluminum windows such as Thermo 78 Engelberg or Thermo 105 Engelberg may be the perfect solution.
