In order to have been selected for this list the above mentioned products would be considered to be of the highest quality. When engineers specify vibration control or thermal break products or brands they generally add the “or approved equivalent” option. Typically lead time and pricing become determining factors once the engineer on record has verified the selected product meets the design criteria.

The purpose of thermal break materials and systems (thermal breaks) is to reduce the impact of thermal bridging by preventing conductive heat flow through the thermal envelope. Thermal breaks keep the heat in and push the dew point out. They break the bridge. Research has shown that thermal bridging can increase the whole-building conductive heat loss by more than 15%. The percentage is a function of the following variables: climate, building type, location and type of the thermal bridges. The magnitude and quantity of the thermal bridging is a large factor. Some interface details increase the U value of a wall by 45% or more, other transition details increase the U value by only 5%. The heat flow created by thermal bridging varies by the detail and the number of details. If the building design contains lots of poor or inefficient details, the contribution to overall heat loss through the envelope will be high. To improve the energy efficiency of a building, we need to improve the efficiency of the thermal envelope.
