Thermal bridges are pathways where heat transfer increases due to higher-conductivity materials (like wood studs or metal fasteners) through insulation.
Trinn-for-trinn guide
- 1Heat flows through low-resistance path, bypassing insulation
- 2Calculate effective R-value accounting for framing fraction
- 3Impact: 10-30% heat loss through bridges in typical construction
Løste eksempler
Inndata
Wall R-19 insulation, 20% area framed with wood (R-6)
Resultat
Effective R ≈ 14.3 (25% lower than ideal)
Framing impact significant
Vanlige feil å unngå
- ✕Ignoring thermal bridge impact in energy calculations
- ✕Using plastic fasteners without verifying strength
Ofte stilte spørsmål
How do you minimize thermal bridges?
Use continuous insulation outside frame, or use low-conductivity fasteners (composites instead of metal).
Are they really important?
Yes, cold spots from thermal bridges cause drafts, condensation, and mold. Addressing them improves comfort significantly.
