Window Cladding Profile System for Thermal Bridge Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carpentry cladding solutions for building renovation often require drilling through existing joinery, leading to thermal bridges and aesthetic issues, especially when trying to improve thermal and acoustic insulation without removing the existing joinery.
Innovation Solution
A cladding system comprising a profile system with an insulator and fasteners that cooperate with fixing means to attach to both the carpentry and support wall, allowing for installation without penetrating the frame, using profiled cooperation means and fasteners like screws or clips to secure the system, which can include mineral wool or synthetic insulation, and optionally a vapor barrier or heavy acoustic mass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If drilling through the existing joinery frame is used to fix the cladding, then the cladding can be securely attached to the structure, but thermal bridges are created and aesthetic appearance deteriorates
Solution Approach 1:
The patent introduces an intermediary fixing mechanism consisting of fasteners that attach to the exterior surface of the frame without penetrating it. The profile system acts as a mediator between the cladding and the frame, distributing attachment forces across the surface while the insulator fills the space between the cladding and frame, eliminating thermal bridges.
2Strength
If drilling through the existing joinery frame is used to fix the cladding, then the cladding can be securely attached to the structure, but aesthetic appearance deteriorates
Solution Approach 1:
The profile system serves as an intermediary element that provides secure attachment through surface-mounted fasteners while maintaining the aesthetic integrity of the original frame. The profiled cooperation means allow for strong mechanical connection without visible drilling or penetration of the frame structure.
3Object-affected harmful factors
If a profile system with insulator is used without penetrating the frame, then thermal bridges are avoided and aesthetics are preserved, but the attachment mechanism becomes more complex
Solution Approach 1:
The fixing mechanism is segmented into distinct functional components: the profile system provides structural support and attachment points, the insulator provides thermal insulation, and the fasteners provide mechanical connection. This segmentation allows each component to be optimized independently while simplifying the overall assembly process.
4Ease of manufacture
If traditional cladding methods are used, then installation is simple, but thermal and acoustic insulation performance is insufficient
Solution Approach 1:
The cladding system uses composite construction combining the profile system (structural element), insulator (thermal and acoustic insulation material), and fasteners (attachment element). This composite structure achieves superior thermal and acoustic insulation performance while maintaining relatively simple installation through the modular design.
