Stanchion Brackets for Wall Insulation Thermal Breaks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for insulating metal building walls result in heat losses due to the compression of insulation between metal wall panels and girts, which reduces thermal resistance.
Innovation Solution
A wall system with laterally extending stanchion brackets or independent tabs that create space between the wall panels and girts, allowing insulation to expand and fill the gaps, thereby reducing direct contact and heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blanket insulation is mashed between wall panels and girts, then insulation is secured in place, but thermal resistance is reduced due to compression
Solution Approach 1:
A bracket system is introduced as an intermediary component between the girts and wall panels. The bracket includes a body portion attached to the girt and a laterally extending tab that protrudes toward the wall panel, creating a gap that prevents direct contact and compression of the insulation material between structural elements.
Solution Approach 2:
The solution extends the insulation space into the lateral dimension by using tabs that protrude horizontally from the bracket body. This creates a three-dimensional gap space that allows insulation to expand laterally without being compressed, transforming the traditional two-dimensional compression scenario into a volumetric insulation arrangement.
2Strength
If wall panels are fastened directly to girts, then structural connection is achieved, but insulation is compressed creating heat loss pathways
Solution Approach 1:
The direct connection between girts and wall panels is segmented into two separate connection points: one between the girt and bracket body, and another between the bracket tab and wall panel. This segmentation allows the bracket to act as a thermal break while maintaining structural integrity through distributed fastening points.
Solution Approach 2:
The bracket serves as a mechanical intermediary that transfers structural loads from wall panels to girts while preventing thermal conduction. The bracket body portion provides the primary structural attachment to the girt, while the laterally extending tab provides secondary attachment to the wall panel, creating a load-path that bypasses thermal conduction through compression.
3Ease of manufacture
If insulation is draped over girts, then insulation installation is simplified, but insulation compression occurs at contact points
Solution Approach 1:
The bracket system is pre-installed on the girts before wall panels and insulation are installed. The tabs extend laterally to create predetermined gaps that guide insulation placement and prevent compression, establishing the thermal break geometry in advance rather than requiring precise positioning during insulation installation.
Solution Approach 2:
The laterally extending tabs automatically create the necessary gap space as wall panels are installed, eliminating the need for manual insulation positioning and compression control. The tabs self-generate the thermal break geometry through their lateral protrusion, allowing insulation to naturally expand into the created space without manual intervention.

Function Achieved in This Case
This configuration significantly reduces heat losses by allowing insulation to fluff out and cover more area, enhancing thermal insulation and minimizing heat transfer between the wall panels and girts.
Implementation Method 1
This space allows a blanket of insulation to be expanded into space created between the tabs. This configuration significantly reduces heat losses by allowing insulation to fluff out and cover more area, enhancing thermal insulation and minimizing heat transfer between the wall panels and girts.

AI summary
Disclosed is a wall system and a method of fabricating that wall. The system uses a stanchion, or bracket. The bracket is installed between the outer flanges of the structural girts that make up the wall and a wall panel. The tabs create space between the girt and panel that enables insulation to be spread out into the additional space created. This reduces heat losses in the wall.
