INHOMOGENEOUS WALL CONSTRUCTIONS
The thermal transmittance (U-value) can easily be calculated and estimated for homogeneous materials and constructions by manually calculating the insulation value for each layer. However, it becomes more complex when accessing the U-value for inhomogeneous constructions. For example, in wall constructions where hollow core elements or blocks are used. These elements will often include irregular cavity spaces, which can be difficult to account for in an area-weighted homogeneous u-value calculation.
The best option for determining the U-value of these inhomogeneous constructions is to perform steady-state finite-element computer simulations, either 2-dimensional or 3-dimensional. If you are not an expert in such simulations, we can assist you by producing a full simulation report on demand for only USD49.
The U-value report can be used to show compliance vis-à-vis the building code and/or green building certification requirements. The simulations can also be a design tool if you are looking for exploring new products and material configurations.
