Why You May Want To Consider Extruded Polystyrene Insulation

With the broad range of insulation options that are on the market, it can prove overwhelming for you as a homeowner to choose what is best for your home. From glass wool to insulation batts, each kind has its specific pros and cons. However, one of the insulation solutions that are gaining popularity among construction contractors and homeowners alike is extruded polystyrene, also known as XPS. The following are reasons why you may want to consider extruded polystyrene for your home's insulation installation project.

Extruded polystyrene has numerous air pockets

When it comes to bulk insulation installation, the driving principle is to ensure there are adequate air pockets in the material. These air pockets function to inhibit thermal gain. Therefore, the more air that your insulation material is capable of trapping, the higher the degree of insulation your home is provided with. XPS is one of the best options for this as it innately has numerous air pockets, which substantially increase its insulating properties.

Extruded polystyrene is resistant to heat

In addition to the natural air pockets that extruded polystyrene has, it is also inherently resistant to heat. This heat resistance lends XPS one of the highest R-ratings when compared to other insulation materials in the market. Extruded polystyrene is typically lined with a layer of aluminium foil on one side to enhance its thermal resistance further. The aluminium foil functions to both block and deflect heat simultaneously, significantly reducing the chances of thermal gain in your home. This exceptional thermal resistance makes XPS an ideal option for Australian households, mainly if your location is characterised by experiencing hot climatic conditions all year round.

Extruded polystyrene is resistant to moisture

A typical concern associated with insulation after a while is water damage. As the insulation becomes old, it is steadily exposed to condensation and other forms of moisture. Materials such as glass wool start to develop mould and mildew due to this moisture exposure. As a result, your residence becomes at risk of a mould infestation from the inside out, and you could end up requiring remediation services. On the other hand, insulation materials such as batts will become compacted when exposed to moisture. The compaction makes the batt insulation ineffective, as it will no longer provide adequate cover for your home. Extruded polystyrene is a much better option as this kind of insulation already comes in compacted form. Therefore, it would not be at risk of water damage. Moreover, the impervious surface of the XPS makes it resistant to the growth of mould.
