Double glazed windows have become increasingly popular in recent years due to their energy efficiency and ability to reduce noise pollution. If you’re considering installing double glazed windows for your plastic windows, there are several things you should know to ensure that you choose the best option for your home. In this article, we will explore 10 things to know when choosing double glazed windows for plastic windows.

  1. What are Double Glazed Windows?

Double glazed windows consist of two panes of glass separated by a layer of gas or air. This layer acts as insulation, preventing heat from escaping during the colder months and heat from entering during the warmer months. Double glazed windows are a popular choice for homeowners looking to improve the energy efficiency and noise reduction of their homes.

  1. Energy Efficiency

One of the main benefits of double glazed windows is their energy efficiency. Double glazed windows can significantly reduce your energy bills by preventing heat loss and gain, reducing the need for heating and cooling systems to work harder to maintain a comfortable temperature. When choosing double glazed windows, look for those with a high energy efficiency rating, such as those with Low-E coatings or argon gas insulation. Choosing the right window profile is very important, see for yourself at the link.

  1. Noise Reduction

Another benefit of double glazed windows is their ability to reduce noise pollution. The layer of gas or air between the two panes of glass acts as a barrier to sound waves, making your home a quieter and more peaceful place to live. Look for double glazed windows with thicker panes of glass or specialized noise reduction features for even better sound insulation.

  1. Type of Glass

When choosing double glazed windows, consider the type of glass used. Different types of glass offer varying levels of energy efficiency, noise reduction, and security. For example, laminated or tempered glass can provide increased security, while Low-E glass can improve energy efficiency.

  1. Window Frame Material

The type of material used for the window frame is also important when choosing double glazed windows. Plastic window frames, such as those made from PVC or UPVC, are a popular option due to their durability, low-maintenance requirements, and affordability. However, other materials such as wood or aluminum may be more suitable depending on your aesthetic preferences or specific needs.

  1. Installation

Proper installation is crucial for the performance and longevity of double glazed windows. Improper installation can lead to air leaks, water leaks, and reduced energy efficiency. It’s important to choose a reputable installer with experience in installing double glazed windows to ensure that your windows are installed correctly.

  1. Cost

The cost of double glazed windows can vary depending on factors such as the size, style, and type of glass used. However, the long-term energy savings and increased home value can make double glazed windows a worthwhile investment.

  1. Maintenance

Double glazed windows require regular maintenance to ensure that they remain in good condition. This includes cleaning the glass, inspecting for damage, and maintaining a tight seal. It’s important to follow the manufacturer’s instructions for maintenance and care to ensure that your windows remain effective and long-lasting.
