What Is the Best Way to Seal Double-glazed Windows?

Summary:
Double-glazed windows offer effective insulation against both sound and heat in buildings, thanks to their unique structure. The quality of the double-glazed glass is crucial in minimizing energy loss, and it largely depends on the type of raw materials used in its production. With high-quality materials, energy loss can be reduced to zero.

Double-glazed windows are highly effective in preventing energy loss, but many people wonder about the best method for sealing them. Proper insulation of double-glazed windows minimizes energy loss, leading to reduced fuel and energy costs. We will delve into the best sealing methods for double-glazed windows and also explore key points for ensuring the insulation is done correctly.

Best Way to Seal Double-Glazed Windows

Double-glazed windows offer effective insulation against both sound and heat in buildings, thanks to their unique structure. The quality of the double-glazed glass is crucial in minimizing energy loss, and it largely depends on the type of raw materials used in their production. With high-quality materials, energy loss can be reduced to zero.
For better insulation in double-glazed windows, rubber seals are usually used. The material of these rubbers is often EPDM. Different qualities of these rubbers are available in the market, but all of them need to be replaced after a period of time. It is interesting to note that the strength and elasticity of these rubbers in reputable brands are examined and measured by special devices. This examination helps to achieve better quality insulation with superior materials.
In addition to rubber seals, the adhesive used on the edges of double-glazed windows also plays an important role in their insulation. However, after a certain period of time, these adhesives need to be replaced as they have a specific lifespan.


 
The adjusters in double-glazed windows are also among the factors that make the window a good insulator for heat and sound. Therefore, if the double-glazed window is well-adjusted, it will be tightly sealed and will also have good insulation. In this article, we have examined the best way to seal double-glazed windows, and we will now refer to important points regarding proper insulation.

What Are the Key Aspects of Insulation?

 
Sometimes, after installing double-glazed windows and over time, you may realize that the window does not provide good insulation for temperature and sound. But what has happened? In such cases, you need to examine a few things in the window.
  • Make sure you have used suitable glass for your window. For example, it is often recommended to use laminated triple-glazed windows in areas with high sound pollution. For example, the use of triple-glazed windows is very common in areas near highways.
  • Thoroughly examine the space around the window frame. It is better to seal the area around the window and the window frame with materials such as Polyurethane and Silicone Sealant.
  • Examine the window opening. If the adjustor is misplaced, the window will not close properly and will not be tightly sealed.
  • Make sure that the rubber seals are not worn out and that you have used high-quality rubber seals. Then, also examine the area around the window opening.

Use of Silicone Mastic Sealant

Silicone sealant is one of the most commonly used materials for sealing double-glazed windows. This adhesive is used alone or in combination with mastics for sealing and outperforms other adhesives such as polymer adhesives, providing more reliable insulation. Silicone adhesives are a combination of oxygen and silicone and can also be used for sealing aluminum windows.


 
This adhesive is designed and produced in various colors, including white, black, gray, transparent, and brown, making it suitable for a variety of uses. However, it is recommended to use the transparent or colorless type when using this adhesive for sealing.

How to Seal Iron Windows?  

Iron windows also require sealing or insulation like other types of windows, and the sealing method for this type of window is similar to other windows. Proper sealing of iron windows can help improve thermal and sound insulation, as well as protect against moisture and damage caused by weather factors.
For sealing iron windows, you can use materials such as silicone sealant. The steps for sealing iron windows are as follows:
  • Cleaning: Before starting the sealing process, clean the area around the window with a mild cleaner. Use cleaners such as isopropyl alcohol or soap and water, and thoroughly clean the area to remove all particles and grease from the surface.
  • Preparation: After cleaning, dry the area around the window with a clean, dry cloth, ensuring that no moisture remains.
  • Cutting the seal: To begin the sealing process, first cut the sealing material to the required dimensions. This material may be in the form of a tube and can be cut with a utility knife.
  • Sealing: Next, place the sealing material in position and fill the gaps between the window and the frame with a sealing substance such as silicone sealant. Spread the sealant uniformly, avoiding the creation of holes or voids in the seal.
  • Cleaning: After applying the sealant, if necessary, clean any excess with a clean, damp cloth. This will contribute to the cleanliness and final appearance of the work.

Keep in Mind That …

  • It is recommended to seal double-glazed windows promptly after installation using silicone adhesive.
  • If sealing is done by a professional, the outcome will be superior.
  • Remember to wear gloves and a mask when working with silicone adhesive to protect your skin. In case of skin contact with the adhesive, be sure to wash it off with soap and water at the earliest opportunity.

How to Seal Aluminum Windows?

To seal aluminum windows, consider the following methods:
  • Use of insulation materials: Utilizing appropriate insulation materials like foam, silicone, etc., can effectively address window sealing issues.
  • Replacement of internal window components: If the internal components of the aluminum window are damaged, it is advisable to replace them.
  • Window replacement: If the aluminum window is old and worn out, replacing it is a better solution to address sealing issues.

Concluding Remarks

Double-glazed windows are an excellent choice for various types of buildings, offering exceptional insulation for energy efficiency and soundproofing, making them widely used. However, issues with the windows can lead to insulation problems. In this article, we have outlined key points for inspecting the insulation and sealing of double-glazed windows post-installation.
