What is Insulation?

Insulation which is used in construction is traditionally a product that is used to create a barrier which sits between the interior of your home and the outside, and will usually vary in temperature.

For example, insulation means that in winter your home will remain warm, even though the exterior of your home is very cold.

This can help you to save significantly on things like your energy bills, on potential maintenance for your home and it will ensure that your home remains comfortable regardless of the time of year.

Insulation can sometimes come in the form of wool sandwich panels that are made from metal, or it might use eco-friendly fibres which are blown in between your outer walls and inner walls.

It can also vary in price as well as the cost of installation, which is why you should always compare your options before committing, particularly if you have a specific budget in mind.

Especially considering that specific insulation might be more effective in individual homes, or climates.

Is Metal Building Insulation Necessary?

In most cases, yes.

You need insulation for your building if you live in a region that experiences temperature fluctuations, as well as cold or hot weather. Building insulation is also an efficient way to save energy.

Even if you live in a stable climate, having building insulation reduces your current and future heating and cooling expenses.

Insulation tackles the two most significant problems facing your building: Temperature Control and Condensation Prevention.

The fact that metal is one of the best heat conductors is bad news for you. What this means is that your building won’t be able to properly retain heat (during winter) or regulate temperature (during summer).

This leaves you vulnerable to excessive heating costs or overheating which causes further damage.

Additionally, when moisture and condensation enter your building, they wreak havoc on the infrastructure by creating rust and mould.

In the next question, you’ll find more information about the adverse effects of condensation.

How Do Moisture and Condensation Pose a Threat to My Building?

Condensation occurs when there is a significant difference in temperature between the inside and outside of your building.

Following this, moisture collects around the unprotected areas – typically the roof and wall – and seeps further into your building.

Moisture stimulates the growth of rust and mould, which are detrimental to your building as they severely weaken the infrastructure, causing further damage in the long-run.

By using building insulation, you can stop this from happening to your building.

How it works is the insulating material acts as a barrier that prevents the cold air from diffusing into your building, as well as the warm air inside from leaking out.

Simply put, installing insulating is akin to implementing an all-in-one solution for a large number of specific problems caused by weather conditions.

Types of Metal Building Insulation?

Depending on your building’s size, design and insulation needs, you are most likely better-suited for certain types of insulation over others.

For example, if your building has a lot of oddly-shaped corners and spaces that are hard to get to, then a flexible Spray Foam building insulation is a far better choice than other insulating materials that come as pre-cut boards.

Fibreglass Blanket (or Batt Insulation)

  • Most budget-friendly and commonly found.

What is the best type of insulation?

Choosing the right building insulation for you and your building typically depends on many different factors, which might include the following:

  • Your budget
  • How much you need
  • Whether you need noise reduction
  • Where in the building it will be
  • How powerful the insulation needs to be
  • If you can DIY your insulation or need professionals

Some types of insulation such as loose filling building insulation might require a specific kind of machine which can blow your insulation into every crack and nook in your building, which means it could potentially require a professional.

Insulated panels, on the other hand, could, in theory, be easily installed and removed, which might make them more suitable for beginners.

Spray foam might be the most budget-friendly from first glance, however, to cover a large space you might need to spend hundreds of dollars on the full kit, whereas panels might end up costing you less per square foot covered.

This is why you should always compare insulation and all of your metal building needs before making any decisions.

How is Insulation Measured?

Insulation is measured through R-values. They estimate the effectiveness of the insulation material to resisting heat flow, air leakage and thereby, condensation.

Higher R-values correspond with higher resistance and are better insulation for your building.

R-values depend on two factors: Thickness of the Material and it’s Heat Conductivity.

Therefore, it is technically possible for insulation with a low R-value per inch, such as Fiberglass Blanket, to raise its R-value by merely adding more layers which increases the material’s thickness.

Although this may seem like an attractive alternative to purchasing expensive building insulation with a higher R-value per inch, you should consider whether it is a cost-effective solution or not.

If you add too many layers, the overall costs may end up being higher, and the installation/removal processes could get even more complicated.

What are the Characteristics of Good Insulation?

Regardless of what type of insulation you choose, there are specific criteria that need to be met to absolutely guarantee the quality and effectiveness of the padding for your building.

If the following standards are met, you are well on your way to making the right insulation choice.

  • Resistant to external conditions including vapour, rain, pests and varying weather conditions
  • Low permeability (ideally a perm-rating of less than 0.1), which protects your building from condensation
  • A radiant barrier that enhances your insulation’s ability to transfer heat and moisture
  • A sufficiently high R-value and proper installation to prevent loss of R-value over time
  • Easy installation and removal process
  • Verification through accredited organisations and reviews

What Else Should I Know Before I Purchase Insulation?

Undoubtedly, insulation is a worthwhile investment to protect your building, prevent it from losing value and reduce your current energy expenses.

Choosing an insulation package is something you want to get right the first time so that it won’t end up costing you more down the line.

Therefore, it is vital that you pick the right provider by understanding the quality and scope of their work, and whether it is the best fit for your building’s insulation needs.

You can go about this by looking over reviews, picture and other information about their current services and previous work.

However, if you want to eliminate the possibility of making the wrong choice, you should consult experts at Green Building Elements for further guidance to help you with your decision.

Through our industry experience, we provide you with in-depth knowledge, essential tips and peace of mind before your final decision.
