Solution Overview
Problem
Existing building thermal insulation methods often require separate installation of ventilation systems, which are inefficient and costly due to low room heights in many buildings, and lack integrated ventilation ducts with soundproofing and insulation properties in external insulation panels.
Innovation Solution
A panel-shaped thermal insulation element with internally housed ventilation channels, formed by removing insulating material during production, using polystyrene rigid foam panels, which maintains low thermal transmittance and includes soundproofing features like micro-perforations, allowing for efficient and cost-effective integration of central ventilation systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ventilation ducts are installed in external insulation panels, then ventilation efficiency is improved, but thermal insulation performance deteriorates due to thermal bridges
Solution Approach 1:
The patent uses micro-perforated soundproofing material with controlled porosity to line the ventilation channels. The micro-perforations allow sound waves to enter and be absorbed through viscous friction and thermal conduction in the porous structure, achieving sound attenuation while maintaining thermal insulation performance by preventing cold bridges.
Solution Approach 2:
The patent creates a composite structure combining the rigid foam insulation material with a flexible soundproofing membrane featuring micro-perforations. This composite design allows the system to simultaneously provide thermal insulation, soundproofing, and ventilation functions without compromising any single performance aspect.
2Ease of manufacture
If ventilation channels are formed by removing insulating material, then manufacturing ease is improved, but thermal bridge development increases
Solution Approach 1:
The patent controls the dimensions and distribution parameters of the ventilation channels to minimize thermal bridge effects. By optimizing channel size, shape, and spacing within the insulation panel, the design achieves adequate ventilation while maintaining thermal performance and avoiding excessive heat loss through the channel structures.
3Object-affected harmful factors
If channels are surrounded by outer wall, then sound transmission is reduced, but gas leakage increases
Solution Approach 1:
The patent introduces a flexible soundproofing membrane with micro-perforations as an intermediary layer lining the ventilation channels. This membrane acts as a mediator that allows air flow while blocking sound transmission and preventing gas leakage, simultaneously addressing both harmful effects through its unique porous structure.
4Object-affected harmful factors
If micro-perforations are added for soundproofing, then sound transmission is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes a pre-manufactured flexible membrane with micro-perforations as a ready-made component. This approach transfers the manufacturing complexity of creating micro-perforations to the membrane production process, where it can be efficiently achieved through specialized equipment, while keeping the overall panel manufacturing relatively simple through lamination or adhesive bonding.

AI summary
The invention relates to an element (2), in particular a panel-type element for thermally insulating a building, said panel being externally mounted on the external wall (1) of a building. The element (2) has channels (3) that can act as ventilation channels. Said channels (3) are surrounded on all sides by the element (2), except in the edge regions. The element (2) is characterised in that the channels (3) extend in individual regions of the element (2) to one edge of the latter (2) in such a way that connections (4) between the channels and the external wall (1) are formed at desired points when the element (2) is mounted on the external wall (1). Air can thus be conducted into the building or out of said building through these connections.
