Insulating Element Duct Stabilization for Facade Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated ventilation systems in thermal insulation composite systems often suffer from damage and reduced effectiveness due to the rough handling of insulating elements during installation, leading to impaired duct cross-sections and stability issues, which compromise the performance of the ventilation systems.
Innovation Solution
A stabilizing arrangement connecting the inner walls of the ducts perpendicular to the main surfaces, with a stabilizing web extending over the channel's axial length, and a design featuring oval or rounded rectangular cross-sections to enhance stability and prevent deformation, along with a self-centering interlocking mechanism for secure and airtight connections between insulating elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If channels are integrated into insulating elements for ventilation systems, then space-saving ventilation arrangement is achieved, but the channels are susceptible to damage and deformation during rough handling on construction sites
Solution Approach 1:
The insulating element is divided into multiple sections by transverse webs that segment the channel into separate compartments. This segmentation provides structural reinforcement to prevent deformation during handling while maintaining the ventilation function through the segmented channels.
Solution Approach 2:
Transverse webs act as intermediary structural elements between the outer shell of the insulating element and the internal channel. These webs provide mechanical support to the channel walls, preventing collapse or deformation during rough handling on construction sites while allowing the channel to maintain its ventilation function.
2Productivity
If channel width is increased in direction parallel to main surfaces for better ventilation, then ventilation effectiveness is improved, but the insulating properties are significantly influenced and thermal bridges are created
Solution Approach 1:
The channel is segmented by transverse webs into multiple smaller compartments. This segmentation allows the total channel width to be distributed across multiple narrow channels rather than one wide channel, maintaining ventilation effectiveness while reducing thermal bridge effects and preserving insulating properties.
Solution Approach 2:
Instead of increasing channel width in the horizontal direction (parallel to main surfaces), the solution uses the vertical dimension (perpendicular to main surfaces) by adding transverse webs that create multiple stacked channel compartments. This dimensional transition maintains ventilation capacity while minimizing thermal bridge formation.
3Reliability
If stabilizing arrangement is added to prevent channel deformation, then channel stability is improved, but device complexity increases
Solution Approach 1:
The stabilizing transverse webs are merged with the channel structure itself, serving dual functions as both structural reinforcement elements and channel dividers. This integration avoids adding separate complex stabilization mechanisms while providing the necessary structural support.
Solution Approach 2:
The transverse webs serve multiple functions simultaneously: they stabilize the channel structure against deformation, segment the channel into ventilation compartments, and provide structural rigidity to the insulating element. This multi-functionality reduces overall device complexity by eliminating the need for separate stabilization components.

AI summary
The invention relates to an insulating element for insulating facades, which is defined by two substantially planar main surfaces extending approximately parallel to one another and by an edge which connects the main surfaces to one another and which at least partially surrounds the insulating element, comprising at least one duct which passes through the insulating element and which is arranged at least partially between the main surfaces, the width of which duct, in a direction extending perpendicular to the longitudinal axis thereof and parallel to the main surfaces, is greater than the height thereof in a direction extending perpendicular to the main surfaces, characterized in that two inner wall regions of the duct that lie opposite one another in a direction extending perpendicular to the main surfaces are interconnected via a stabilizing arrangement.
