Interface Gasket for Building Envelope

The Interface Gasket for Building Envelope is designed to enhance the installation of windows and other objects into building openings. This gasket assembly features an inner and outer frame connected by an elastic material, providing a secure seal, improved energy efficiency, and easier installation. 

Description

The Interface Gasket for Building Envelope is a sophisticated solution for attaching windows to panel openings in buildings. The assembly comprises an inner frame and an outer frame, both made from rigid materials, connected by an elastic material that forms a continuous circumferential seal. This design ensures that the gasket assembly supports the window securely in the panel opening while forming an airtight and watertight seal.

Key features include:

• Inner and outer frames: These are shaped to match the perimeter of the window and panel opening, respectively. The inner frame is often Z-shaped, while the outer frame is L-shaped, ensuring robust structural integrity.
• Elastic material: This component bridges the gap between the inner and outer frames, providing flexibility and elasticity. The material can be polyurethane, rubber, or nylon, with a Durometer Shore Hardness of 20A to 90A. It supports the window’s weight without significant deformation.
• Gap flanges: Embedded in the elastic material, these flanges enhance the stability and sealing capabilities of the assembly.
• Hydrophobic properties: The elastic material is hydrophobic and free from surface defects, ensuring long-lasting performance in various environmental conditions.

The gasket assembly not only simplifies the installation process but also eliminates thermal bridges, significantly enhancing the building’s energy efficiency. The innovative design and materials used ensure durability, ease of installation, and superior sealing performance.

Benefits

• Energy efficiency: Reduces thermal bridging, improving insulation and reducing energy costs.
• Ease of installation: Simplifies the window installation process, saving time and labor.
• Durability: Made from robust materials that withstand environmental stress.
• Versatility: Suitable for various objects, including windows, doors, vents, and more.
• Improved sealing: Ensures a watertight and airtight seal, enhancing building envelope performance.

Applications and Industries

• Commercial and residential construction: For installing windows, doors, and other fixtures.
• Energy-efficient buildings: Ideal for projects focusing on reducing energy consumption.
• Modular construction: Suitable for prefabricated building components.
• HVAC systems: Useful for installing wall-mounted air conditioners, vents, and ducts.
• Renovation projects: Enhances the retrofitting of older buildings with new, energy-efficient windows and fixtures.
