There are many materials for home insulation. We know some of them, such as polystyrene or glass wool, for years. Others like hemp or cork are new, natural materials, which we have been hearing about more and more recently. At the global level, things change and in addition to the effective insulating characteristics of the material, new selection criteria appear. However, a thermal insulation must meet certain conditions in order to be considered effective.
Thermal insulation of residential and commercial building is necessary to minimize heat losses in winter and prevent heat from entering during summer. In addition to increased comfort, you also reduce the energy costs required for heating or cooling the building.
The insulation can be done during the construction of the house, or added later to the walls, basement or roof.
Thermal insulating materials, natural or not, are chosen according to their performance, and this is determined by several parameters:
- Thermal conductivity - determines the ease with which heat passes through the material.
- Thermal resistance - is the parameter that links the conductivity to the thickness of the insulating material.
- Thermal diffusivity - is the ability of a material to conduct heat relative to that of its storage.
- Density - a high density material has a high overall weight which means it has low thermal diffusivity.
- Vapor permeability - Thermal insulation Lansing MI offers must be vapor permeable, otherwise the building will develop mold problems.
