Embedded Furring Member in Composite Building Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional building insulation methods using cavity insulation between studs lead to thermal bridging, causing condensation issues, reducing indoor air quality, and increasing energy consumption due to inefficient heating and cooling, while continuous insulation methods with girts and fasteners create additional thermal bridges and are labor-intensive to install.
Innovation Solution
A composite building panel with a central body of expanded polymer matrix and an embedded furring member that reduces thermal bridging by integrating the furring member within the panel, providing a lightweight, easy-to-install solution that minimizes condensation risks and enhances thermal performance, allowing for efficient heating and cooling while simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cavity insulation between studs is used, then insulation is provided in the wall cavity, but thermal bridging occurs through the studs reducing thermal performance
Solution Approach 1:
The patent combines the furring member and insulation support functions into a single integrated component embedded within the insulation layer. This merging eliminates the need for separate girts and fasteners that create thermal bridges, while maintaining structural support for cladding. The integrated design allows the furring member to be positioned optimally within the insulation cavity without creating additional thermal pathways.
Solution Approach 2:
The patent extracts the furring member from the traditional external positioning and embeds it within the insulation layer. This extraction removes the furring member from the external thermal environment where it would create thermal bridges, and relocates it to a position surrounded by insulation material, thereby eliminating its contribution to thermal bridging while maintaining its structural function.
2Loss of energy
If continuous insulation with girts is used, then thermal performance improves, but additional thermal bridges are created by girts and fasteners
Solution Approach 1:
The patent merges the furring member and insulation support functions into a single integrated component embedded within the insulation layer. This eliminates the need for separate girts and fasteners that create thermal bridges, while maintaining structural support for cladding. The integrated design allows the furring member to be positioned optimally within the insulation cavity without creating additional thermal pathways.
Solution Approach 2:
The furring member is pre-positioned and embedded within the insulation layer during the insulation installation process itself, rather than being added as a separate subsequent step. This preliminary action integrates multiple functions into a single installation phase, reducing the number of steps and labor required compared to traditional methods that require separate installation of continuous insulation, girts, and fasteners.
3Loss of energy
If continuous insulation with girts is used, then thermal bridging is reduced, but labor intensity increases due to multiple installation steps

AI summary
A composite building panel includes: a central body comprised of an expanded polymer matrix having a first face and an opposing second face, a top surface and an opposing bottom surface, and a first side surface and an opposing second side surface; and a furring member extending horizontally across the central body between the first side surface and the second side surface proximate to the top surface. The furring member comprises: a bottom portion having at least one expansion hole such that the expanded polymer matrix extends therethrough, thereby embedding the bottom portion in the expanded polymer matrix; a first side portion extending perpendicularly from the bottom portion; and a second side portion extending perpendicularly from the bottom surface. One of the side portions extends from the bottom portion beyond the top surface of the central body.
