Thermal Bridging

What Is Thermal Bridging?

As we know heat makes its way from heated space towards the outside from path where it can have the least resistance. A Thermal Bridge acts as a bridge transferring heat or cold thermal energy through the member or temperature difference between inside and outside. 

Thermal Bridging helps in decreasing interior room surface temperatures and an increase in heat loss. This can also be a passage for moisture transfer. Nowadays many places heat is so high that moisture transfer can be neglected.

The steel studs are designed as thermal bridges to provide maximum possible conductive energy transfer across a wall using a minimum amount of material. Heat transmission through walls is the greatest factor in energy loss in a residential building which can range from 8% to 40%. 

If we study in deep, we can not make out how high heat losses are due to thermal bridges. And, members which act as thermal bridges the heat flow density changes and usually result in a reduction in surface temperature. Aerogels, it is material with the highest thermal insulation value. But, the material is very fragile to use as a building material. The aerogels are transformed to, by nano-technology, called Thermablok Composite. Thermablok is used to control thermal bridging in walls
