Junctions and thermal bridges

Junctions and thermal bridges

In a building that meets the Passivhaus Standard the junctions and interfaces require specific attention. It is at these points in the building fabric that heat loss can occur through thermal bridges; furthermore low surface temperatures can result in surface condensation and mould growth. Unaddressed thermal bridges can increase fabric heat loss by over 30%. This chapter considers the impact that thermal bridging and reduced surface temperatures can have upon building performance.
