Can cardboard boxes help insulate your home?

Homeowners are always on the lookout for ways to save money on their energy bills. Insulation is an important part of this as it helps to retain heat, prevents it escaping and in turn lowers the amount householders spend on bills to keep their homes warm. In short, as a homeowner looking to save money, the benefits maximising on the efficiency of insulation within your home can bring are impossible to ignore.

 

With this in mind, more and more homeowners looking to reduce costs have increasingly been discussing the use of cardboard boxes to insulate a property and reduce energy costs in the process. In this blog, we take a look into this unusual phenomenon to see how effective insulating your home in this way really is.

 

Material Properties

When we look at cardboard as a material, there are characteristics that would suggest it does hold value when it comes to insulation. Most cardboard, more specifically corrugated cardboard, features air pockets – a trait that is seen across many materials used for insulation by tradespeople. When we consider this, it is understandable that many homeowners may conclude that it is therefore an effective insulation material.

 

But does it work?

Put simply, yes it does. Cardboard has air pockets between two layers and this slows down the transfer of heat from one side to the other, and any warm air that gets into the air pocket can stay between these layers for a long period of time and maintain its temperature. So technically it does work, but it’s safe to say that placing some cardboard boxes in the attic obviously won’t insulate a property as effectively as materials that are designed specifically for that purpose.

 

Can it save money significantly?

Although plain cardboard will provide insulation to a certain degree, it is unlikely to result in a change substantial enough to effect a significant decrease in energy bills. In order for a material to be an effective insulator, it must be evenly distributed across an entire surface and maintain a consistent density throughout. It is important, therefore, that this is communicated to homeowners who may otherwise think they are saving money on their energy bills with DIY cardboard insulation – as the reality is they won’t be.

 

If homeowners are looking to make significant savings on their energy costs, installing a design-for-purpose insulation material instead can achieve savings of up to £140 per year when installed correctly.

 

Will it last?

One important thing to note is that because cardboard is not created specifically for long term insulation purposes, there are other things that can go wrong in addition to it not performing well. The slightest exposure to moisture, due to humidity for example, can result in the cardboard material becoming mouldy or breaking down completely. Mould can cause undesirable smells within a home, and can also be detrimental to the health of people living within the property too.

 

If you are an insulation provider, it is extremely important that you and your colleagues can confidently respond to similar claims from homeowners who may believe there is more to the power of cardboard when it comes to maximising on home insulation than there really is. At Thermorend we offer training and guidance in the application of revolutionary insulation technology, as well as the theory that goes along with it.
