Flood Precast designed, supplied and installed roof slabs for this school project.

Flood Super Wideslab’s® design exploits the thermal mass properties of exposed soffit, a viable option by virtue of Flood Precast’s Class B finish, which can be painted directly. The precast planks act as a heat sink, absorbing excess energy from sources such as heating and sunlight when it is available, and releasing it back into the building as it cools, so in turn saves costs on heating the building.

What is thermal mass?

Thermal mass is a term that describes the ability of a material to store heat; something many construction materials can do to a greater or lesser extent. But, to be useful in the built environment, they must also be able to absorb and release heat at a rate roughly in step with a building’s daily heating and cooling cycle. Precast Concrete products can do this well and, being dense materials, can also store a lot of heat. Other building materials such as timber also can however they absorbs heat too slowly to offer much effective thermal mass, and steel conducts heat too rapidly to be in sync with a building’s natural heat flows over the day.
