With so many different types of insulation available, it might seem as though it can be difficult to identify which types of insulation are best for your situation. Therefore, we aim to help you understand the differences between the two and make an informed decision when it comes to identifying which one might be right for you.
Before we delve into the main differences between the two, it’s important to identify where and why these two types of insulation are used.
If you consider roof insulation, this option will only be required should you be using your loft as a living space. This means that you have had your loft converted and it is now a room. In this instance, it will mean that you will need to install insulation in between the rafters instead of between the joists while you can also take advantage of a number of insulation materials too.
If you do choose to insulate your loft then this will mean that it is nothing more than a void that might be used for storage at best. Therefore, you can choose to put insulation material in between and over the joists, making it the cheapest insulating option for your home.
This is a relatively simple form of insulation and it can be installed quickly and efficiently should access to your loft be readily available. You will need to make sure that you don’t have problems with damp or condensation too. In this case, rolls of mineral wool will be used and they will be rolled out between the joists in your loft. The joists are the wooden beams that run along the floor of your loft. The insulation will be installed in one direction before a second layer is placed on top at right angles to cover the joists.
You might be wondering about how you can use your loft as storage space once you have loft insulation installed. However, it is possible although it is recommended that you install boards across the top of the joists. The main thing to consider here is that you do not squash down the insulation as this would reduce its effectiveness. Therefore, it is recommended that the level of the loft floor is raised which would mean that the insulation would sit below the floor and would not be compressed, ensuring it does its job correctly.
If loft insulation is not a possibility because the space is being used as a room then roof insulation is the next option. This simple solution will see insulation fitted between and over the top of rafters, which are the sloping beams that give your roof its pitch. In this instance, you can use rigid insulation boards that are cut to size or you can use foam insulation that is sprayed between the rafters.
If the loft is difficult to access then the insulation can be blown into awkward spaces with the materials being used range from mineral wool fibre, polyurethane foam or treated cellulose.
If you have a flat roof, then this would need to be insulated from above and that would involve having insulation boards placed on top of the roof before a weatherproof layer is added on top of the insulation.
There is no denying that both loft and roof insulation provide significant benefits. Without loft or roof insulation, you are going to lose a lot of heat and energy and that will lead to an increase in your bills. However, when you choose to have insulation installed, you will be able to keep your home warm while saving energy and keeping bills low. Furthermore, loft insulation is long-lasting which means that it will continue to deliver results for some time. Neither one is better than the other but the choice you make will all come down to how you use the space in your loft.
So, what savings can you make when you choose to have insulation installed?
- detached house – £215
- semi-detached house – £130
- mid-terraced house – £115
- detached bungalow – £185
There are grant schemes that are available for roof and loft insulation although you will be required to meet specific criteria to access it. However, once you do have insulation installed, it will pay for itself because of the savings you can make.
