Casement Fly Mullion

About Casement Fly Mullion

The Casement Fly Mullion uPVC profile is a specific type of mullion used in casement window systems to hold the fly or insect mesh sash. It is designed to provide a secure, supportive frame for the fly screen, which can be opened or closed independently from the main glass sash.

Profile Description:

• The Fly Mullion is a slender, strong profile that integrates seamlessly with casement window frames.
• Typically made of durable, weather-resistant uPVC with a standard wall thickness around 2 to 2.5 mm.
• Dimensions generally align with the 60 Series casement profiles, around 60 mm width, providing structural integrity to the fly screen section.
• Incorporates features for easy installation of insect mesh and ensures a tight seal to keep insects out.

Function and Application:

• Used to create a separate frame for the openable insect mesh in casement windows.
• Maintains proper spacing and alignment between the fly screen and the main glass sash.
• Designed to accommodate gaskets and seals to enhance weatherproofing and insect protection.
• Helps in ventilation while preventing entry of insects, dust, and debris.

Benefits:

• High durability with resistance to UV radiation, moisture, and environmental wear.
• Easy to fabricate and integrate with other standard uPVC casement window profiles.
• Low maintenance, retaining color and shape over years despite exposure to sun and rain.
• Provides aesthetic and functional enhancement to window systems by offering a well-fitted, seamless fly screen solution.

In summary, the Casement Fly Mullion uPVC profile is key for mounting and supporting openable insect screen systems in casement windows, combining durability, proper sealing, and ease of use within the 60 Series casement profile family.
