Insulating Window Frame Mounting With Heat-Insulating Spacer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof window fastening systems suffer from suboptimal thermal insulation due to direct contact between mounting brackets and window frames, and are difficult to assemble and disassemble due to the coverage of installation sheet metal angles by insulating blocks.
Innovation Solution
Incorporating a heat-insulating spacer between the holding element and the window frame, allowing the holding element to be securely fastened to the structure without direct contact, and designing the spacer to fit within the insulating block to maintain accessibility and prevent thermal bridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting brackets are directly fastened to the window frame, then secure fastening is achieved, but thermal insulation deteriorates due to cold bridges
Solution Approach 1:
A heat-insulating spacer is introduced as an intermediary element between the mounting bracket and the window frame. This spacer prevents direct thermal contact while maintaining mechanical fastening, thereby eliminating cold bridges and improving thermal insulation without compromising fastening security.
2Object-affected harmful factors
If insulating blocks are installed to improve thermal insulation, then thermal insulation is enhanced, but accessibility to mounting brackets deteriorates
Solution Approach 1:
The mounting system is segmented into distinct functional elements: the mounting bracket for fastening, the heat-insulating spacer for thermal isolation, and the insulating block for additional insulation. This segmentation allows each component to perform its specific function without interfering with others, maintaining accessibility while providing comprehensive thermal insulation.
3Reliability
If mounting brackets are large-area to ensure secure fastening, then fastening reliability is improved, but thermal bridges are exacerbated
Solution Approach 1:
The heat-insulating spacer is designed with localized contact areas that match the mounting bracket's fastening points. This local quality approach ensures that thermal insulation is provided precisely where needed, maintaining fastening reliability while minimizing thermal bridge formation at the contact points.
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
This solution provides enhanced thermal insulation by preventing cold bridges and simplifies assembly and disassembly by keeping the holding element freely accessible, while ensuring secure fastening and load transfer.
Implementation Method 1
the holding element is fastened to the frame with the interposition of at least one heat-insulating spacer. Due to the interposition of the heat-insulating spacer, the retaining element has no direct contact with the window frame, so that there is no thermal or cold bridge leading to the window.

AI summary
The window (1) i.e. residential roof window (2), has a holder (6) for fastening the window to a structural body by a fastening screw. The holder has a holding element (7) e.g. metal sheet bracket (9), for holding the window. The holding element is attached to a window frame (3) of the window and to the structural body. A heat insulation block (14) is arranged between the window frame and the structural body and attached to the window frame. The holding element is fastened to the window frame by interconnection of a plastic heat insulating spacer (18).
