When a building is made of steel, there is often a problem with adequately maintaining heat or cold. Regular steel building insulation is not adequate by itself because of a process called thermal bridging. |
What is thermal bridging?
Thermal bridging occurs when two items that are not good insulators come in contact with each other. When this happens, heat and cold are transferred regardless of the materials that are surrounding them.
What types of thermal bridging can occur?
There are the repeating bridges which follow a regular pattern, non-repeating thermal bridges can occur with a cavity wall and a single lintel, and geometrical thermal bridges where two different planes come in contact with each other.
What is cavity insulation?
This type of protection is put into a structure in between the structural frame such as wood, beams, studs, metal frames, etc. It is prone to thermal bridging.
What is continuous insulation?
According to the U.S. Department of Energy Building Codes Program, continuous insulation is a filling that “runs continuously over structural members and is free of significant thermal bridges.” Most often this type of filling is in the form of foam.
What are the benefits of continuous protection?
Obviously, the main benefit is the elimination of thermal bridges. Thus, steel building insulation does not lose the heat during the winter or cool air during the summer as much. This can amount to substantial savings in the power bills. Another benefit is that it prevents condensation from building up at the top of the purlin, thus increasing the overall performance.
