Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal insulation panels, including XPS, EPS, and composite panels with polyiso foam, exhibit poor reaction-to-fire properties, making them unsuitable for applications with fire risk.
Innovation Solution
A composite thermal insulation panel comprising a rigid polyurethane foam core with glass fibre coating layers added with mineral additives, providing high fire resistance and mechanical strength, and optionally a support layer of non-combustible materials, enhances fire resistance and structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional thermal insulation panels (XPS, EPS, polyiso) are used, then thermal insulation performance is achieved, but reaction-to-fire properties are poor
Solution Approach 1:
The patent applies composite materials by combining a polyurethane foam core with glass fibre coating layers containing mineral additives. This composite structure integrates the thermal insulation properties of polyurethane foam with the fire-resistant characteristics of glass fibres and mineral additives, achieving both thermal performance and improved fire resistance in a single panel system.
Solution Approach 2:
The patent applies local quality by concentrating fire-resistant materials (glass fibres and mineral additives) specifically in the coating layers that directly face potential fire exposure, while the core insulation material maintains its thermal insulation function. This localized application of fire-resistant properties optimizes the overall fire performance without compromising thermal insulation throughout the entire panel structure.
2Reliability
If glass fibre coating layers with mineral additives are added, then fire resistance is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated panel structure. The glass fibre coating layers containing mineral additives serve dual purposes: they provide fire resistance while also acting as the outer protective surface of the panel. This consolidation of fire protection and structural surface functions into one component reduces overall system complexity despite the advanced materials used.
Solution Approach 2:
By creating a composite material system where glass fibres and mineral additives are integrated into the coating layers, the patent achieves fire resistance as an inherent property of the panel structure itself rather than as a separate protective layer. This integration simplifies the overall device by making fire protection a built-in characteristic of the insulation panel.
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 panel achieves improved fire resistance, mechanical strength, and dimensional stability, making it suitable for applications with fire risk without compromising thermal insulation performance.
Implementation Method 1
the coating layer of glass fibre added with mineral additives and having reaction-to-fire class B-s1,d0, which during installation can be advantageously placed on the side most exposed to the risk of fire, is effectively able to protect the insulating sheet behind from fire
Implementation Method 2
an insulating sheet of rigid, closed-cell polyurethane foam (e.g. Polyiso - PIR)
Implementation Method 3
the expanded polyurethane foam that makes up the insulating sheet can be formed directly on the first coating layer, which remains joined/fixed to it thanks to the adhesiveness of the polyurethane being formed
