Hollow Insulating Spacer for Cladding Thermal Break
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spacers used in building construction, typically made of steel, act as heat conductors, compromising the thermal insulation properties by transferring heat through insulating materials, thereby defeating the purpose of insulation.
Innovation Solution
The development of improved insulating spacers with a simplified structure, manufactured through extrusion as continuous profiles, featuring a constant cross-section and fastener insertion paths that allow for pre-attachment of cladding elements, forming a captive assembly with low heat conductivity materials like fiberglass-reinforced polymers, which reduces thermal conductivity and enhances handling ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel spacers are used to attach cladding elements to building structures, then structural strength and fastening reliability are improved, but thermal insulation performance deteriorates due to heat conduction through the steel spacer
Solution Approach 1:
The spacer is constructed as a composite structure combining steel components (for strength and fastening) with insulating material (for thermal isolation). The insulating material fills the interior space of the hollow steel spacer, creating a composite element that simultaneously provides structural support and thermal insulation, thereby resolving the contradiction between strength and heat conduction.
2Reliability
If complex spacer structures with multiple components are used, then attachment reliability and positioning precision are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
Multiple functions previously requiring separate components (structural support, thermal insulation, fastening guidance, cladding attachment) are merged into a single integrated spacer unit. The hollow steel spacer with insulating material and built-in fastener insertion paths combines all these functions, simplifying the overall assembly while maintaining attachment reliability and positioning precision.
3Object-affected harmful factors
If spacers with large interior spaces are used to accommodate insulation material, then thermal insulation effectiveness is improved, but the spacer becomes more prone to deformation and requires additional support structures
Solution Approach 1:
The combination of steel (high strength-to-weight ratio) and insulating material (low thermal conductivity) creates a composite spacer that maintains structural stability despite the hollow interior space. The steel framework provides rigidity and resistance to deformation, while the insulating material fills the space to maximize thermal insulation without adding significant weight or complexity.

AI summary
A spacer for retaining a cladding element on a building element in a spaced apart relationship has a constant cross-section in its longitudinal direction. The spacer is an at least substantially hollow structure having at least one external wall enclosing an interior space. At least one fastener insertion path extends through the interior space. The fastener insertion path is capable of holding a fastener disposed therein prior to mounting the spacer and cladding element on the building element. The spacer preferably comprises planar surfaces on opposite sides thereof that are configured to abut the cladding element and the building element, respectively.
