Window Putty vs Silicone: Which One is Better for Your Window Installation?

When it comes to installing windows, one of the most crucial steps is applying the correct type of sealant. There are two popular options available - window putty and silicone. Both have their own set of advantages and disadvantages, which can make it difficult to decide which one is best suited for your project.

In this article, we will delve into the differences between window putty and silicone, helping you make an informed decision about which sealant to use for your window installation.

Window Putty

Window putty is a traditional type of sealant that has been used for centuries. It is a mixture of linseed oil, calcium carbonate, and pigments, which provides a durable and flexible bond between the glass panel and the frame. One of the advantages of using window putty is its ability to expand and contract with the wood, reducing the risk of cracking or breaking.

However, window putty has some limitations. It can be prone to mold and mildew growth, particularly in humid environments. Additionally, it may require more frequent maintenance to ensure that it remains effective.

Silicone

Silicone is a popular alternative to traditional window putty. It is a synthetic sealant that offers several benefits over its traditional counterpart. Silicone is waterproof, making it an excellent choice for areas prone to high humidity or moisture.

One of the major advantages of using silicone is its ease of application. It can be easily applied with a caulk gun and does not require any special tools or equipment. Additionally, silicone is less likely to mold or mildew than window putty, reducing the need for frequent maintenance.

Comparison

When deciding between window putty and silicone, it is essential to consider several factors, including the type of application, environmental conditions, and personal preferences. Here are some key differences between the two:

* Durability: Both window putty and silicone offer durable seals, but silicone may be more resistant to extreme temperatures and weather conditions.

* Maintenance: Silicone requires less maintenance than window putty, as it is less prone to mold and mildew growth.

* Application: Window putty may require more specialized tools and equipment for application, while silicone can be easily applied with a caulk gun.

In conclusion, both window putty and silicone are viable options for sealing windows. When choosing between the two, consider the type of application, environmental conditions, and personal preferences. While window putty offers traditional benefits, silicone may provide more modern advantages in terms of ease of application and durability. Ultimately, the decision comes down to your specific needs and requirements.
