Flame Retardant Coated Insulation Panels for ETICS Fire Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal insulation panels made of combustible materials like polystyrene foam pose fire safety concerns due to their combustible nature, leading to undesirable color deviations and increased fire risk, necessitating improved fire behavior without complicating the insulation system's design or production.
Innovation Solution
A thermal insulation panel with flame retardant coatings applied directly to specific side surfaces, forming a fire barrier that prevents fire spread while maintaining the panel's simplicity and cost-effectiveness, and ensuring adhesion and appearance are not compromised.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flame retardant coatings are applied to all surfaces of thermal insulation panels, then fire resistance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies flame retardant coating only to specific side surfaces of the thermal insulation panels that are in direct contact with adjacent panels, rather than coating all surfaces. This localized approach targets the critical fire spread pathways while reducing material consumption and manufacturing complexity.
Solution Approach 2:
The patent segments the coating application by identifying and treating only the relevant side surfaces where fire spread occurs between panels, separating the fire protection function from the entire panel surface and applying it only where necessary.
2Reliability
If flame retardant materials are embedded throughout the insulation board, then fire spread is prevented, but production cost and complexity increase
Solution Approach 1:
The patent extracts the flame retardant function from the bulk insulation material and concentrates it on the side surfaces through coating application. This separates the fire protection function from the thermal insulation function, allowing each to be optimized independently.
Solution Approach 2:
The patent creates a composite structure by combining the thermal insulation panel material with a flame retardant coating layer on specific surfaces, merging two different material functions into a single integrated component.
3Reliability
If plaster is applied over flame retardant treated surfaces, then fire protection is maintained, but adhesion and appearance are compromised
Solution Approach 1:
The patent applies flame retardant coating only to the side surfaces that contact adjacent panels, leaving the plaster-receiving surfaces untreated. This ensures that plaster adhesion and appearance are not compromised while still providing fire protection at the critical interfaces.
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 solution significantly enhances fire resistance by containing fire spread and maintaining the panel's original dimensions and appearance, with cost savings from targeted coating application and reduced material usage, ensuring effective fire protection without altering the system's design complexity.
Implementation Method 1
The side surfaces are provided with a coating containing flame retardants... In the event of a fire, the heat causes the flame retardant to foam and harden, thereby stabilizing the separating layer
Implementation Method 2
In the event of a fire, the heat causes the flame retardant to foam and harden, thereby stabilizing the separating layer
