GFRP Rebar - Low Thermal Conductivity
Minimizes heat transfer in reinforced concrete for energy-efficient and thermally stable structures
Why Thermal Conductivity Matters
Steel rebar conducts heat, creating thermal bridges that reduce energy efficiency and can lead to temperature-driven stresses or condensation inside buildings. In contrast, GFRP rebar offers exceptionally low thermal conductivity.
- Reduces unwanted heat transfer through concrete
- Helps maintain indoor thermal comfort
- Prevents thermal cracking and bridging issues
Ideal for Energy-Efficient Design
GFRP is well-suited for buildings and infrastructure that require thermal insulation performance, such as:
- Passive houses and net-zero energy buildings
- Insulated concrete forms (ICFs)
- Cold storage facilities and freezers
- Bridges and decks in freeze/thaw zones
Consistent in All Temperatures
GFRP rebar remains dimensionally stable under extreme heat or cold, unlike steel which expands and contracts rapidly. This stability contributes to longer-lasting concrete and reduced thermal fatigue.
- Low coefficient of thermal expansion
- Maintains bond integrity under temperature swings
- Avoids internal stress fractures in concrete
Eliminate Thermal Bridges with GFRP
Choose GFRP rebar for structures where energy efficiency and thermal insulation are critical — from smart buildings to extreme climate infrastructure.
