Wall systems reduce thermal bridging by interrupting direct heat flow paths through the building envelope and maintaining continuous insulation and structural alignment. Thermal bridging occurs when heat passes through conductive materials such as steel or concrete, bypassing insulation and reducing overall energy efficiency.
In green construction, controlling thermal bridging is essential because energy performance depends on the behavior of the entire wall assembly—not just individual components.
What Is Thermal Bridging?
Thermal bridging happens when materials with high thermal conductivity create a direct path for heat to move between interior and exterior surfaces.
Common causes include:
- steel framing that connects indoor and outdoor environments,
- gaps in insulation continuity,
- poorly detailed wall transitions,
- and misaligned enclosure layers.
These conditions lead to:
- higher heating and cooling demand,
- uneven interior surface temperatures,
- condensation inside wall cavities,
- and reduced occupant comfort.
Why Thermal Bridging Matters in Green Construction
Green construction aims to reduce energy waste and improve long-term building performance.
Thermal bridging undermines these goals by:
- lowering the effective R-value of wall assemblies,
- increasing operational energy use,
- creating cold surfaces that attract moisture,
- and accelerating material degradation.
A wall system that controls thermal bridging supports:
- consistent indoor temperatures,
- lower energy demand,
- improved moisture control,
- and longer service life.
Introducing the KRATOS™ Wall System
Steel Framing Without Thermal Bridging
The KRATOS™ Wall System is designed to address thermal bridging at the system level rather than as a patchwork of added layers. It integrates multiple wall performance functions into a single engineered assembly that maintains continuous insulation while providing structural framing.
Rather than relying on separate trades and sequential layers to achieve enclosure performance, the system is manufactured with built-in alignment between structure, insulation, and moisture control layers.
Structural Framing Without Direct Thermal Paths
Traditional steel framing creates frequent thermal bridges because metal members form continuous conductive paths from interior to exterior.
The KRATOS™ Wall System uses:
- galvanized light-gauge steel framing,
- pre-punched service holes for electrical and plumbing,
- and an assembly layout that supports continuous insulation across the wall face.
This approach reduces:
- metal-to-exterior contact,
- heat transfer through framing members,
- and interruptions in the thermal envelope.
Insulation Integrated Into the Wall Assembly
Thermal bridging is often made worse when insulation is added after framing is installed, creating gaps or compression.
The KRATOS™ Wall System incorporates:
- closed-cell spray foam insulation,
- rigid exterior sheathing,
- and impact-rated mesh layers,
to provide R-16+ thermal performance from the factory.
Because insulation is integrated into the wall system:
- thermal continuity is preserved,
- installation variability is reduced,
- and performance becomes more predictable.
Moisture and Air Control as Part of Thermal Performance
Thermal bridging and moisture problems are closely related.
Cold surfaces created by thermal bridges:
- attract condensation,
- trap moisture inside wall cavities,
- and increase the risk of mold growth.
The KRATOS™ Wall System integrates:
- closed-cell spray foam,
- and exterior sheathing layers
to function as a combined water-resistive barrier (WRB) and air barrier.
This limits:
- uncontrolled air movement,
- vapor intrusion,
- and moisture accumulation within the wall system.
Continuous Exterior Sheathing and Thermal Break
A key contributor to thermal bridging is the lack of a continuous thermal break between framing and exterior conditions.
The KRATOS™ Wall System includes:
- impact-rated continuous exterior sheathing,
- insulative layers that interrupt heat flow,
- and a surface ready for cladding attachment.
The MX7 series adds:
- increased structural integrity,
- fire and impact resistance,
- a fastening surface for finishes,
- and reduced carbon footprint through material efficiency.
This continuous exterior layer functions as both:
- a thermal break, and
- a structural and protective component.
Systems Thinking vs Layered Construction
Traditional construction relies on separate materials installed in sequence:
- framing,
- insulation,
- moisture barrier,
- exterior sheathing.
Each layer is vulnerable to:
- misalignment,
- installation gaps,
- and performance conflicts.
The KRATOS™ Wall System approaches wall design as a coordinated assembly rather than a stack of parts. This reduces:
- interface failures,
- unintended thermal paths,
- and long-term degradation.
Green construction depends on this type of systems thinking to achieve consistent enclosure performance.
How Green Building Solutions Addresses Thermal Bridging
Green Building Solutions develops wall systems that align with green construction performance standards by emphasizing:
- continuous thermal insulation,
- minimized conductive heat paths,
- integrated moisture and air control,
- and dimensional stability over time.
The KRATOS™ Wall System reflects this approach by combining structural framing, insulation, moisture control, and exterior sheathing into a coordinated wall assembly that supports thermal efficiency without relying on disconnected components.
Thermal Bridging as a Green Building Performance Metric
Reducing thermal bridging leads to:
- lower energy consumption,
- improved comfort,
- reduced condensation risk,
- and longer wall system life.
From a green construction perspective, this improves:
- operational efficiency,
- environmental performance,
- and lifecycle cost control.
Thermal performance is therefore a defining quality of wall system design, not an optional enhancement.
