Let’s get technical: How does each type of popular insulation work in your home?

Insulation is what keeps your home nice and warm when it’s freezing outside, and helps to limit the amount of energy that can escape through your walls, floor and ceiling.

We’ve all heard about insulation and why it’s important, but do we know about the features, benefits and downfalls of each individual measure? With so many options available to you, it might be necessary to recognise which form of insulation would be best for your situation, in order to save yourself the most money on your energy bills.

As experts in the field, we’re best placed to outline the most popular types of home insulation, as well as explaining how it works and what its best features are…

External Wall

Not only can external wall insulation upgrade the thermal performance of your home, but it can also upgrade it’s external appearance. The process involves our team of professionals fixing an insulation layer to the existing wall, with a protective render or decorative finish.

If your house was built prior to 1930, it means that it was likely constructed with solid walls, so it doesn’t have cavities that can be injected with insulation. So, instead of suggesting cavity wall for your property, we’ll suggest solid wall. The purpose of insulating in this manner is to slow the movement of heat out through the walls, thereby dramatically reducing heating demand.

Cavity wall

Perhaps the most well-known form of insulation, cavity wall insulation works to reduce the heat lost through the walls of your home. This is achieved by filling the air space, or ‘cavity’, in the middle of the walls with insulating material that limits the heat transfer.

This captures the air within the cavity walls, preventing as much heat from escaping and reducing heating costs for your home. There are different types of cavity wall insulation, including a Urea Formaldehyde Foam, or Polystyrene Beads, that can fill up as much space as possible within the wall.

The less empty space for heat to easily move means the more energy efficient a room is. So, to recap, cavity wall insulation is great for limiting the heat lost, or cold entering, through the walls of your home, but what about the floor?

Underfloor

Have you ever walked into a room and immediately noticed that the floor is much colder than the rest of the space? This is because cold air can enter your home through the floor, which initially cools it down, before transferring to the rest of your home.

This can drastically increase your monthly heating bills, and all for the sake of keeping your toes warm! Underfloor heating works by creating a barrier that protects your home from the air that flows beneath your property. Most underfloor insulation consists of thick, dense material that doesn’t allow for heat transfer, and stops the cold from making its way inside.

A negative point about this method of insulation is that it is more costly and time consuming to set up to pre existing houses, and is a lot easier to add alongside the build of a new property. This is why most modern homes come with underfloor insulation as standard.

Loft

Loft insulation works by reducing the amount of heat lost from your roof – reducing the amount of fuel you need to burn for heating and saving you money. When your home is heated, a lot of that heat escapes through your roof, both through conduction and convection. The most common form of loft insulation is fibreglass, which is a thick coarse material that is a really effective insulator.

Which should I choose?

So, we have been through the most popular forms of insulation for a home, as well as their individual benefits, but which one should you go for? The simple answer is, all of them.

If you were to have all three insulation methods added to your home, you would see your energy efficiency rating increase tenfold.
