BCLP-092- Revit Essentials -Curtain Walls

Curtain Walls in Architecture

·?????? Curtain walls are integral to contemporary architectural designs, serving as non-load-bearing exterior walls that provide weather protection, insulation, and aesthetic appeal to buildings.

·?????? They are characterized by their lightweight construction and are often made of materials like aluminum frames with glass, metal panels, or thin stone infills.

·?????? Unlike traditional load-bearing walls, curtain walls rely on the building's structure for support and are attached to it.

Components and Construction:

·?????? Curtain walls typically consist of several key components:

·?????? Mullions:

o?? Vertical or horizontal structural elements that divide the wall into panels and provide support for the infill material. Mullions are essential for the overall stability and integrity of the curtain wall.

·?????? Grid Lines:

o?? Lines that define the placement of mullions on the wall. Grid lines help architects and designers visualize the layout of the curtain wall and ensure uniformity in design.

·?????? Infill Materials:

o?? The material used to fill the space between mullions. Common infill materials include glass, metal panels, or thin stone, each offering different aesthetic and functional properties.

Types of Curtain Walls:

·?????? In architectural design software like Revit, curtain walls are categorized into different types to accommodate various design requirements:

·?????? Curtain Wall 1:

o?? This type offers maximum flexibility as it does not come with preset grids or mullions. Architects have complete freedom to design custom curtain walls according to their specific needs.

·?????? Exterior Glazing:

o?? This type provides preset grids that can be customized as needed, offering a balance between flexibility and structure.

·?????? Storefront:

o?? Designed specifically for storefront applications, this type comes with preset grids and mullions. It provides a standardized design solution while still allowing for customization.

Embedded Curtain Walls:

·?????? Embedded walls allow for the seamless integration of walls into the host structure, making them ideal for creating storefronts or unique architectural features. Key considerations for embedded walls include:

·?????? Behavior:

o?? Embedded walls behave similarly to windows and maintain their position relative to the host wall, even when the host wall is modified.

·?????? Integration:

o?? Tools like the Cut Geometry tool facilitate precise integration of embedded walls into the host structure without the need for extensive editing of wall profiles.

Type-Driven Curtain Element Layout:

·?????? Specifying the layout by type allows architects to streamline the design process by placing instances with predefined panels, grids, and mullions. This approach enhances efficiency and consistency in curtain wall design by:

·?????? Simplifying Design:

o?? Architects can quickly create curtain walls with consistent layouts and parameters, reducing the time and effort required for manual adjustments.

·?????? Ensuring Consistency:

o?? Type-driven layouts help maintain consistency across multiple instances of curtain walls within a building or project, ensuring a cohesive architectural design.

Locking Mullions and Curtain Grids:

·?????? Mullions and curtain grids can be pinned (locked) on a curtain element, ensuring consistency in design across multiple instances. This feature is particularly useful when employing a type-driven curtain grid layout. Key points include:

·?????? Consistency:

o?? Locked mullions and grids ensure that all instances of a curtain wall have consistent structural elements, maintaining design integrity throughout the building.

·?????? Flexibility:

o?? While locked, mullions and grids can still be customized within the constraints of their respective types, allowing for some degree of flexibility in design.

Creating and Modifying Curtain Walls:

·?????? Architects have the flexibility to create and modify curtain walls to suit specific design requirements. Techniques include:

·?????? Linear and Non-Linear Designs:

o?? Curtain walls can be created in both linear and non-linear configurations, allowing architects to adapt them to various building shapes and layouts.

·?????? Orientation Adjustment:

o?? Designers can adjust the orientation of curtain walls to ensure optimal placement and alignment within the building structure.

·?????? Cleaning Join Conditions:

o?? Tools like the shape handle allow architects to separate curtain wall joins from adjoining walls, providing greater control over mullion placement and ensuring design intent is preserved.
