A structural insulation panel is a type of building panel often used in residential walls, floor and roof areas. The typical structural insulation panel consists of two structural boards between which there's a core made of foam plastic. These panels have high insulation value when used in construction-related projects around the house.

The use of structural insulation panels is increasingly becoming popular with modern construction specialists. Discussed below are a few questions about the use of structural insulated panels meant to serve as an introduction to their use for the benefit of prospective new homeowners.

Which Plastic Foam Is Used In These Panels And Why?

In a large number of cases, structural insulated panels have their core made of Expanded Polystyrene (EPS) as the plastic foam of choice. EPS has a closed cell structure that almost entirely inhibits the penetration of heat and/or cold into the insulation panel, hence its superior thermal insulation.

EPS is preferred for use on structural insulated panels for various reasons. Top on the list of these reasons is that EPS has commendable shock absorption despite its lightweight nature. Shock absorption is important in insulated panels as it reduces the likelihood that insulated panels will fall apart upon exposure to a high-impact force.

Lastly, Expanded Polystyrene is a non-hygroscopic material. As such, structural insulation panels are not likely to suffer moisture damage during their lifespan.

Isn't EPS Flammable?

Polystyrene is a flammable material.  This is often an issue of concern for homeowners worried that structural insulation panels may be a fire hazard around the house.

Expanded Polystyrene is used in a variety of applications including food packaging. However, EPS used in the fabrication of structural insulation panels is treated with fire retardant additives at the production stage. For this reason, a large number of insulated panel manufacturers refer to the EPS they use as Modified Expanded Polystyrene.

As such, structural insulation panels have reduced affinity to fire.

Are Structural Insulated Panels Eco-Friendly?

Many prospective new homeowners are often concerned the environmental impact of insulated panel installation.

However, choosing to install these panels is an environmentally conscious decision. This is because the fabrication of insulated panels employs the use of fully recyclable materials. The two structural boards used on panels are made of timber, which is easily recycled. Consequently, the use of structured insulation panels reduces the need to cut down new trees for timber production. Expanded Polystyrene is also a recyclable material.
