Kako izračunati Thermal Bridge
Kaj je Thermal Bridge?
Thermal bridges are pathways where heat transfer increases due to higher-conductivity materials (like wood studs or metal fasteners) through insulation.

Worked Examples
Vnos
Wall R-19 insulation, 20% area framed with wood (R-6)
Rezultat
Effective R ≈ 14.3 (25% lower than ideal)
Framing impact significant
Common Mistakes to Avoid
- ✕Ignoring thermal bridge impact in energy calculations
- ✕Using plastic fasteners without verifying strength
Frequently Asked Questions
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.
