Confused by U-Values and R-Values?
Do you know the difference?
We want to ensure that you understand every step of this process, so you know you’re getting a customer-orientated service. That’s why we’ve decided to break down our process into simple steps and explain terms we commonly use, in this case, we’re going to explain thermal values.
These values are measurements that you will need to take into account when choosing an insulation material or looking at the effectiveness of what is installed.
R-Value – Material’s thermal resistance assessment – this is something which applies to materials used in a structure (whereas a U-Value does not look at the performance of specific materials).
U-Value – This is calculated by adding all of the R-Values – this figure will then be used in a calculation: 1 divided by the total of all the R-Values.
The figure you have calculated will be the U-Value.
The higher the total value of the R-Values, the lower the U-Value. The building regulations that are in place will outline what U-Value your property needs to achieve.
Radiant Heat Transfer is another important factor to take into account – it is something you need to be aware of.
Glasswool and chemical foam insulation is the traditional form of loft insulation – the purpose of it is to slow heat flow to help keep heat in your home but they do provide a barrier to radiant heat transfer.
Conduction heat transfer is the cause of 75% of properties’ total heat loss. This happens when a flat surface is hit by heat, which then causes the surface’s temperature to increase.
By including a radiant heat barrier, you can help to improve overall insulation performance, ensuring comfort in your home, while also saving you money.
SuperFOIL’s multifoil insulation is an effective barrier to all 3 forms of heat transfer, providing industry-leading performance, at a competitive rate.
