Fire-Resistant Glazing With Integrated Intumescent Edge Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-resistant glazings require time-consuming installation of intumescent tapes at the point of installation, which can lead to user errors, incompatibilities, and potential damage, compromising fire resistance and safety.
Innovation Solution
A fire-resistant glazing design that incorporates an intumescent edge mass between the glazing sheets, eliminating the need for separate intumescent tapes during installation, and allowing for a larger application of intumescent material to fill frame cavities effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intumescent tape is applied separately during installation, then fire resistance can be improved, but installation time and complexity increase
Solution Approach 1:
The patent combines the intumescent tape function with the glazing edge seal by integrating the intumescent material directly into the seal structure. This merging eliminates the need for separate intumescent tape application, reducing installation time while maintaining fire resistance functionality.
Solution Approach 2:
The intumescent material is pre-installed as part of the seal structure during manufacturing, before the glazing is installed in the frame. This preliminary action ensures that the fire protection function is already in place, eliminating the need for separate installation steps and reducing on-site time.
2Reliability
If intumescent tape is applied manually during installation, then fire protection can be enhanced, but installer error and damage risk increase
Solution Approach 1:
By merging the intumescent function into the seal structure, the patent eliminates the separate manual application step that is prone to errors. The integrated design ensures consistent and reliable installation without depending on installer skill level or precision.
3Object-affected harmful factors
If intumescent tape is used to block frame rebate, then smoke and heat transmission can be prevented, but the tape may be damaged during installation
Solution Approach 1:
The patent merges the intumescent material with the seal structure, eliminating the separate tape component that is vulnerable to damage during installation. The integrated design ensures the fire protection function remains intact while removing the weak link of separate tape application.
4Reliability
If separate intumescent tape is applied, then fire barrier can be improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions (sealing and fire protection) into a single integrated component, reducing the number of separate elements that need to be installed. This simplification reduces installation complexity while maintaining the fire barrier function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The intumescent edge mass ensures better adhesion, reduces installation complexity and costs, enhances fire resistance by filling gaps, and prevents smoke and heat transmission, conforming to various regulatory standards.
Implementation Method 1
in the event of a fire and upon exposure to high temperatures, the intumescent tape expands and generates a foam and/or a damp course
Implementation Method 2
the intumescent tape expands and generates a foam and/or a damp course
