13 Interesting Insulation Facts (2023)

Insulation for your home is a key part of keeping your energy bills down and your home warm and comfortable.

However, there are many misconceptions about insulation, and it’s important to understand the key facts about it. Here are 13 interesting facts about insulation you should know:

1) Recyclable heating solution

Insulation is a recyclable and reusable heating solution. It can be used multiple times, making it one of the most sustainable and eco-friendly ways to keep your home warm.

In fact, cellulose insulation is made up of 85% recycled paper product and 75% of mineral wool insulation is post-industrial recycled content. While it may not be as much as our other two examples, fibreglass insulation is often made up of up to 60% recycled materials.

2) Insulation is always working

It doesn’t matter if the temperature drops during the depths of winter or soars during the summer months, insulation is always working.

Installing this energy-saving measure can help keep your home comfortable at a more consistent temperature all year round.

That means unless it gets damaged, insulation will always be working hard to stop any energy from being wasted.

3) Cost-effective home improvement

If you’re looking for a cost-effective way to save money on your energy bills and make your home more comfortable,  insulation is the perfect choice.

While it could initially be seen as a large cost, insulation will pay for itself within five to six years and will continue to pay for itself several times over within its 40-year lifespan.

4) Major savings on the average utility bill

Considering that the heating and cooling of the property make up 54% of the average utility bill, insulation can be seen as a great way to reduce your costs.

With the right level of insulation, you could save up to 40% on your utility bills and make sure that you’re not wasting any energy.

Through loft insulation alone, a detached property could save up to £590/year on energy bills and 1000 kg of carbon emissions.

5) Uninsulated homes lose more than 60% of their energy

It’s estimated that 40% of UK homes have poor or very poor wall insulation, a staggering figure that will be costing homeowners hundreds of pounds extra a year in their utility bills.

Uninsulated properties lose 60% of their energy through walls, ceilings, and floors that are not properly insulated.

In fact, as of December 2020, there were an estimated 8 million uninsulated lofts in the UK. Considering that 25% of energy is lost through the roof – that’s some major money going down the drain!

6) Upgraded insulation can increase your home’s value

We know that installing new insulation can help save on your energy bills, but did you know it can also boost your average house price?

By improving your home’s Energy Performance Certificate from a D to a C, you could increase your house value by 3%. But an increase of two bands could see an 8.8% increase.

7) R-value used to measure insulation

An insulation material’s ability to resist heat flow is measured by its R-value. This figure represents the material’s thermal resistance, and this number is used to determine how much insulation is needed for a particular space.

The higher the R-value, the better your insulation will be at keeping out cold air and trapping warm air inside your home.

For example, fibreglass insulation has an R-value of R-2.75 to R-5.25 per inch, while spray foam has an R-value of R-3.6 to R-6.5 per inch, depending on the density of the foam.

8) Insulation slows heat transfer, not airflow

A common misconception about insulation is what it actually does. Some think that insulation is used to block air leaks or stop unwanted airflow when in reality it is designed to slow heat transfer.

Insulation reduces the rate at which heat radiates through your walls and ceilings. This means that air will continue to flow through a property, but it won’t lose temperature as quickly when travelling from one space to another.

9) Reduces carbon dioxide naturally

Insulating a house is a great way of reducing your energy output and improving your carbon footprint.

Because insulation lowers the demand for energy needed to power your property, it also helps to reduce the number of carbon dioxide emissions released into the atmosphere.

This natural air pollutant is a major contributor to global warming and climate change, so by using insulation you’ll be lowering your carbon footprint and contributing towards a greener world.

10) Dates back to the Mediaeval era

Some of the first recordings of insulation date all the way back to the Mediaeval era, when people would stuff their walls with a mixture of mud and straw to keep the heat in and the cold out.

Vikings also used a similar method, combining mud and clay to insulate their homes and improve the structural integrity of their property.

11) 10 different insulation varieties

Today, there are 10 different types of insulation available on the market. This includes spray foam, loose fill, rolled fiberglass, rigid foam board, reflective foil and more.

Each material has its own unique properties and benefits that are tailored to suit different applications and environments. Discover which is the best material for each retrofitting insulation solution in our post.

12) Air sealing is essential

When installing insulation, it’s important to remember that air sealing is also essential. This involves using caulk and spray foam to seal any cracks, gaps or holes in your walls and ceilings before adding insulation.

Sealing the attic with caulk can prevent a wealth of potential leaks after the insulation is added, helping to prolong the loft insulation’s 30 year lifespan.

This will help prevent cold drafts from entering the property and reduce energy loss. It will also ensure that the insulation material you use performs to its maximum potential.

13) UK homes could get free insulation

Through the Energy Company Obligation Scheme (ECO4) and the Great British Insulation Scheme (formally ECO Plus), you could benefit from free (or heavily discounted) insulation for your home.

Thousands of UK homes have already taken advantage of this government grant, improving the energy efficiency of their home and reducing their energy bills.

However, there are eligibility criteria that must be met before you benefit from ECO4 or the Great British Insulation Scheme, as only the nation’s most energy-inefficient properties can get a free grant.
