Any self-builder will say that working on your home by yourself is very different from having contractors do it. It takes a lot of time and energy, but you’ll save money and probably love the end product a lot more.

When choosing insulation, self-builders need to think about more than just the price. Here are three important aspects that need to be considered:


When it comes to particular types of insulation, DIY projects are simply not a good option. Take spray foam as an example. For small projects, it’s relatively easy but insulating your walls with it is not a one-man job.

First of all, rule out any insulators that you don’t know how to use. You may be tempted just to improvise, but that can lead to heat bridges and cold spots. There are many easy-to-use materials so stick to those.

See if you need any tools to do the job. Particular insulators need special pumps to be applied. Check that before buying something because getting tools you’ll only use once isn’t worth it.

Some materials can cause allergies, itchiness and even illnesses. Fibreglass has these problems. If you’re not prepared to deal with them, choose something else.

For a self-builder with little experience or patience, multifoils or blankets are an excellent choice. The multifoil insulator has the advantages of being thinner and not making a mess during installation.

You don’t have to spend whole days on insulating your home. Pick the right material. You’ll be done fast, and you won’t sacrifice the quality of your house.

Let’s not forget the reason you are insulating your home in the first place. You need the house to be well-insulated to cut down on expenses as well as protect the environment.

You also have to consider the state regulations regarding the U-value of the house. To make sure that you adhere to the laws, get the U-value calculated. That should be a main priority while choosing insulation.

After you know what your goals are, see to it that the insulation reaches them. There are three types of heat transfer (conduction, convection and radiation) and you must take all of them into account.

Most insulators absorb heat. Multifoil insulators, however, reflect radiant heat back to the source. That is preferable because it is equally useful in the summer as in winter.

Lastly, be careful while applying the insulation. Poor installation can lead to significant losses in effectiveness. Just buying the right material isn’t enough.


When choosing insulation, look for something with a long lifespan. Products that last a year aren’t worth your trouble. Think ahead so you don’t spend money needlessly.

Most insulators that absorb heat become less efficient when exposed to moisture. Rockwood blanket, for example, can even develop mould in those conditions. Either make sure there is little moisture or get materials that are unaffected, like foil.

Do some research on your preferred insulator. See if it’s fragile or susceptible to the elements. Some products may need occasional maintenance or cleaning to stay at peak efficiency.


Consider the three aspects mentioned above and see what is in your price range. If you’re not convinced about one product, don’t worry. Some insulators can be used together, often yielding even better results.
