EPS Insulation Panel Fixing System Eliminates Thermal Bridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal and acoustic insulation materials, such as polystyrene, have low stiffness, requiring metallic fixing means that create thermal and acoustic bridges, compromising the insulation performance of building walls.
Innovation Solution
A fixing system for tiles using steel brackets integrated into a sintered expanded polystyrene (EPS) panel with graphite, assembled via a bayonet fitting into porcelain stoneware tiles, eliminating direct metallic contact with the wall and allowing thicker insulation panels, and using a non-metallic glue for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metallic fixing means are used to secure tiles to the wall, then the tiles can be firmly attached, but thermal and acoustic bridges are created that worsen insulation performance
Solution Approach 1:
The patent introduces an intermediary element - a plastic fixing profile that mediates between the metallic fixing means and the tile. This plastic profile acts as a thermal and acoustic break, preventing direct contact between metal fixtures and the tile while still providing secure attachment. The profile is inserted into recesses in the tile and secured to the wall with metallic anchors, thereby eliminating thermal and acoustic bridges while maintaining attachment strength.
2Object-affected harmful factors
If insulating materials are placed directly against the wall, then thermal and acoustic insulation is achieved, but the low stiffness requires metallic fixing means that create thermal bridges
Solution Approach 1:
The patent merges the insulating material with the fixing system by integrating plastic fixing profiles directly into the insulating panel structure. The profiles are embedded in recesses within the insulating material during manufacturing, creating a unified component that provides both insulation and fixing functions. This integration eliminates the need for separate fixing elements and reduces overall system complexity while maintaining insulation performance.
3Object-affected harmful factors
If thicker insulating panels are used, then insulation performance is improved, but the assembly process becomes more difficult and time-consuming
Solution Approach 1:
The patent segments the fixing system into modular components - multiple plastic fixing profiles distributed across the insulating panel - that can be independently installed and secured. Each profile is a separate unit with its own recesses and attachment mechanisms, allowing for distributed fixation points that simplify installation of thicker panels. The modular nature enables easier handling and positioning compared to monolithic fixing systems.
