Best Materials in Insulated Panel Fabrication

Thermal insulation is the most practical way to enhance energy-efficiency in your building. The material will prevent heat loss and gain, therefore the heating and cooling system will not have to strain when the weather is adverse. This will translate into lower long-term electricity costs and there will be minimal repair requirements since the HVAC unit will not be overworked. In addition, good thermal insulators will also improve the sound attenuation in your living space. This will limit the need to install separate acoustic insulation materials. If you are thinking about using compact insulated panels for your home, consider choosing one of these materials.

Expanded Polystyrene

Polystyrene is a popular polymer in the fabrication of insulating panels. The material is derived from by-products of petroleum and natural gas and it is available as a foam board or in a mould. Expanded polystyrene is a distinctive type of insulation which is made by fusing small beads of the plastic resin to create the panels. These are exposed to steam which causes the thermoplastic to become softer and expand. These are commonly incorporated into the walls, floors and ceilings of the home to prevent heat exchange. The expanded polystyrene material is beneficial because the material is fire-retardant. The material has high density and is stable, so you will enjoy long-term insulation in your home. Additionally, the panels are resistant to moisture, therefore these can limit condensation and growth of mould on the structure.

Extruded Polystyrene

The fabrication process for extruded polystyrene is different from the aforementioned expanded alternative technique. Therefore, the qualities of the two materials are considerably different. These insulating panels are made by melting polystyrene plastic. The molten material is exposed to pressure when solidifying to create rigid sheets. The resulting product is a favourable insulating material because the panels will be highly resistant to moisture. This means that your interior space will be free from condensation, mildew and structural rot. On the other hand, the panels are thin, so they will not provide the same level of thermal insulation as the expanded polystyrene products.


Polyisocyanurate is gaining popularity in the insulation market alongside the common polystyrene materials. This material is fabricated by exposing the plastic raw resin to high temperatures. The product is a rigid foam which can be used in walls and roofing of buildings. Typically, aluminium foil is used to laminate the foam to prevent shrinkage when exposed to moisture.

Choose a qualified technician for insulated panel installation because the set-up will affect the function.
