The thermal performance of your walls, floors and ceilings can greatly affect the energy efficiency of your building. When considering the three T’s, taking insulation in to consideration can play a huge part in increasing your building’s thermal performance.
The thermal performance of your building affects the amount of heat being transferred between the inside and outside environments. Increasing the thermal performance of a building decreases the ability of heat to move between the two environments.
In order to measure the thermal performance of a section of a building, a Total Resistance Value (RT-Value) is provided. This value measures the total thermal performance of that component of the building. The higher the RT-Value, the better the thermal performance.
A double brick cavity wall for example, has an average thermal performance of RT-Value of R0.68m²K/W. When insulation is included in the cavity, the RT-Value will increase. For example, by including Kingspan AIR-CELL Permicav XV flexible insulation in the cavity of the same double-brick cavity wall, the RT-Value would increase to R1.8m²K/W, thereby improving the thermal wall performance by 165%
Insulation has been used for years to increase the thermal performance of buildings and as technology evolves, and the thermal performance of insulation increases, the ability to block the transfer of heat has increased.
