Low-Conductivity Spacer Clip for Wall Insulation Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in retaining insulation in place between Z girts and sheathing members during wall construction until exterior cladding is applied, and creating a thermal break between these components.
Innovation Solution
A spacer clip made of low thermal conductive materials like nylon or polyurethane plastic is attached to Z girts, positioned between the Z girts and sheathing members to create a thermal break and retain insulation in place, working in conjunction with retainer clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If Z girts are mounted directly on sheathing members, then structural support is provided, but thermal transfer occurs between the Z girts and sheathing members
Solution Approach 1:
The spacer clip serves as an intermediary component between the Z girt and sheathing member. It provides structural support through its spring clip portion that engages with the sheathing member, while its low thermal conductive material body creates a thermal break, preventing direct thermal contact between the metal Z girt and the sheathing member.
2Temperature
If insulation members are positioned between Z girts, then thermal insulation is improved, but the insulation needs to be retained in place until exterior cladding is applied
Solution Approach 1:
The spacer clip performs multiple functions: it provides structural support by engaging the sheathing member, creates a thermal break to improve thermal insulation, and retains insulation members in place through its positioning between the Z girt and sheathing member, eliminating the need for separate retention mechanisms.
3Temperature
If a thermal break is created between Z girts and sheathing members, then thermal performance is enhanced, but additional components are required
Solution Approach 1:
The spacer clip is designed as a multi-functional component that simultaneously provides structural support through its spring clip portion, creates a thermal break with its low thermal conductive material body, and retains insulation members. This consolidation reduces the need for separate components for each function.
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
The spacer clip effectively maintains insulation in place and provides a thermal break between Z girts and sheathing members, enhancing the thermal performance of wall assemblies by preventing heat transfer.
Implementation Method 1
The spacer clips are attached to Z girts mounted on studs to create a thermal break between the Z girts and the outer sides of sheathing members and the inner sides of insulation members

AI summary
A spacer clip comprised of a low thermal conductive material is secured to the Z girts of a wall assembly to provide a thermal break between the Z girts and the sheathing members of the wall assembly and to also provide a thermal break between the sheathing members and the insulation members of the wall assembly.
