Curtain Wall Insulation Hangers for Fire-Resistant Transom Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulation systems for zero spandrel curtain wall structures require numerous parts and pieces, leading to complex and time-consuming installations, and are prone to premature failure in fire conditions due to mechanical attachments to vertical mullions that can melt under fire exposure.
Innovation Solution
A curtain wall insulation system utilizing insulation hangers that attach only to horizontally disposed transoms, eliminating mechanical attachments to vertical mullions, and incorporating a safing insulation compression-fitted between the curtain wall insulation and floor slab, with reinforcing members for added stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insulation systems use mechanical attachments to vertical mullions, then the insulation is securely anchored, but the system is prone to premature failure in fire conditions due to mullion melting
Solution Approach 1:
The patent removes the insulation attachment from the vulnerable vertical mullions entirely. Instead, the insulation is supported by horizontal transoms that are less susceptible to fire damage, extracting the attachment function from the harmful thermal environment of the mullions.
Solution Approach 2:
The patent introduces horizontal transoms as intermediary support elements between the insulation and the building structure. These transoms serve as a mediator that provides secure anchorage without exposing the insulation to the same fire risks as direct mullion attachment.
2Adaptability or versatility
If conventional insulation systems use multiple parts and pieces, then the insulation can be adapted to fit the framework, but the installation becomes more difficult and time-consuming
Solution Approach 1:
The patent combines multiple separate insulation components into a single integrated insulation assembly that can be installed as one unit. This merging reduces the number of parts to be handled and installed, thereby reducing installation time while maintaining adaptability to the framework through the assembly's overall design.
Solution Approach 2:
The patent segments the insulation system into modular units that can be easily transported and installed. The insulation is divided into manageable sections that can be fitted to the framework and then connected, simplifying the installation process while maintaining versatility.
3Strength
If conventional insulation systems use T-shaped backer bars and L-angles, then the insulation is reinforced and secured, but the system requires more parts and complex installation
Solution Approach 1:
The patent merges the reinforcement function into the insulation assembly itself rather than requiring separate backer bars and L-angles. The insulation is designed with integrated reinforcement features that provide the necessary structural support without adding separate components.
Solution Approach 2:
The patent removes the separate backer bar and L-angle components from the system entirely. The reinforcement function is extracted from these separate metal elements and integrated directly into the insulation assembly, reducing part count while maintaining strength.

AI summary
A system for insulating a curtain wall structure is disclosed. The system includes a plurality of insulation hangers, a curtain wall insulation, and a safing insulation. The insulation hangers include a reinforcing member that engages a horizontal transom of the curtain wall structure. The system is attached only to horizontal transoms of the curtain wall structure via the insulation hangers to provide ease of installation and/or enhanced reliability.
