Solution Overview
Problem
Existing methods for ensuring an air gap between exterior wall panels and insulation are costly, complex, and prone to errors, failing to adequately address moisture penetration and energy efficiency, and often compromise the waterproofing of building membranes.
Innovation Solution
A system utilizing Z-shaped components that attach to the existing wall and exterior paneling, creating a uniform air gap and allowing for the secure retention of insulation panels without direct fastening to the wall, using rods and pegs to maintain insulation panels between Z-shaped components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate strip components are used to maintain air gap, then air gap compliance is achieved, but device complexity and installation cost increase
Solution Approach 1:
The Z-shaped component merges the air gap maintenance function with the insulation panel attachment function into a single integrated component. The component includes a first leg that attaches to the insulation panel and a second leg that maintains the air gap from the cladding, eliminating the need for separate strip components while achieving both air gap compliance and secure insulation retention.
2Manufacturing precision
If multiple separate components are used for air gap and insulation retention, then air gap is maintained, but installation time and cost increase
Solution Approach 1:
The Z-shaped component combines air gap maintenance and insulation panel retention into a single integrated component, reducing the number of parts to be installed and assembled. This single component performs both functions simultaneously, significantly improving installation efficiency while maintaining air gap compliance.
Solution Approach 2:
The Z-shaped component is designed to perform multiple functions: attaching to the insulation panel, maintaining a uniform air gap from the cladding, and providing a retention mechanism for the insulation panel. This multi-functionality reduces the total number of components needed and simplifies the installation process.
3Strength
If insulation is fastened directly to wall sheeting, then insulation is secured in place, but waterproofing membrane integrity is compromised
Solution Approach 1:
The Z-shaped component acts as an intermediary between the insulation panel and the cladding system. It provides a retention mechanism that secures the insulation panel without requiring direct fastening to the waterproofing membrane, thus maintaining waterproofing integrity while ensuring insulation retention through its structural design and attachment 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 simplifies the installation process, ensures consistent air gaps for improved energy efficiency and moisture management, while maintaining the integrity of waterproof membranes by avoiding direct fastening through the use of Z-shaped components and holding elements.
Implementation Method 1
This air gap creates a reflective barrier, where the hot or cold air radiating from the exterior wall panel is reflected by the insulation layer due to the presence of the air gap.
Implementation Method 2
moisture may still penetrate. Despite moisture penetration, good airflow will wick away water before mold and other destructive consequences set in. For this reason, sound construction practices, and in some instances, building code, require that exterior wall panels are separated from insulation material by a gap to facilitate air circulation and water drainage.

AI summary
Disclosed is a system of cladding along an existing exterior wall of a building featuring a plurality of girt component, further comprising a plurality of Z-shaped components and a plurality of edge components deployed in a spaced apart arrangement and at an angle to each other, with an insulation material inserted between any two of the girt components. The girt components enforcing an air circulation and moisture gap between exterior wall paneling and insulation. The plurality of girt components may contain a slots that further provide air circulation and water drainage and provide anchor points for holding elements that securely attaches insulation material between adjacent girt components onto an existing wall, without unnecessarily breaching exterior sheeting or weather membrane that may be present on an existing wall. The use of clips, pegs or rods further speeds the installation process and reduces the cost and efficiency of insulation, while improving the thermal isolation of components attaching to the girt components.
