Sealed unit packers, often referred to as Packers, are an essential component in the construction and glazing industries. These small but crucial pieces play a significant role in ensuring the stability and durability of glass units when installed in windows, doors, and other structures. In this article, we will delve deeper into what sealed unit packers are, their importance, and how they are used in various applications.
What are sealed unit packers?
Sealed unit packers are small plastic or composite shims that are used to create a space between the glass and the frame in a sealed unit. These packers are typically placed at the edges of the glass unit to provide support and prevent any movement that could compromise the integrity of the installation. They are available in different thicknesses, ranging from 1mm to 12mm, to accommodate various glass sizes and dimensions.
The Importance of sealed unit packers
Sealed unit packers play a crucial role in the installation of glass units for several reasons. Firstly, they help to create a uniform gap between the glass and the frame, which is essential for proper sealing and insulation. This gap allows for the movement of the glass due to temperature changes without putting any stress on the unit, thereby preventing breakage or damage.
Additionally, sealed unit packers help to level and align the glass within the frame, ensuring a secure and stable installation. By providing support at the edges of the glass, packers help distribute the weight of the unit evenly, reducing the risk of stress fractures or cracks over time. This is especially important in large glass installations where the weight and size of the unit can put additional strain on the frame.
How sealed unit packers are Used
Sealed unit packers are typically placed at the corners and along the edges of the glass unit before it is installed in the frame. The packers are inserted between the glass and the frame, ensuring that the glass is level, aligned, and properly supported. Once the glass unit is in place, the packers help to hold it securely in position while also providing the necessary gap for sealing materials such as silicone or sealant.
In some cases, sealed unit packers are also used to adjust the angle or pitch of the glass within the frame. By adding or removing packers at strategic points, installers can ensure that the glass is positioned at the correct angle to prevent water pooling or excessive glare. This level of customization and precision is crucial for achieving a high-quality and professional glass installation.
Applications of Sealed Unit Packers
Sealed unit packers are used in a wide range of applications within the construction and glazing industries. They are commonly used in window and door installations, where they help to secure and support glass units within the frame. Additionally, packers are also used in curtain wall systems, glass facades, and other architectural installations where large glass units are required.
Sealed unit packers are also essential in double and triple glazing systems, where they help to create the necessary air gaps for insulation and energy efficiency. By using packers of varying thicknesses, installers can customize the gap between the glass layers to achieve the desired level of thermal performance. This makes sealed unit packers a vital component in modern energy-efficient building designs.
In conclusion, sealed unit packers are a small but crucial element in the construction and glazing industries. Their role in providing support, stability, and insulation for glass units cannot be understated. By understanding the importance of sealed unit packers and how they are used in various applications, installers can ensure that their glass installations are of the highest quality and durability.
