Choices that influence the cost price of cavity wall insulation
If you wish to have cavity wall insulation installed in your home, there are various choices that can have a significant impact on the cost price. We’ve made an extensive list of these various choices for you:
Choice 1: Cavity wall or not?
The first choice is not really a real choice, but it is extremely important. You have to ask yourself whether or not your house has a cavity wall. Older houses usually don’t have a cavity wall. Newer houses may have a cavity, but it’s not uncommon for it to be insulated already. If your house doesn’t have a cavity wall, there are still options to insulate. You can still insulate your facade for example. However, the use of real wall insulation is considerably more expensive. The cost price for this usually starts somewhere around of 8,720 dollars.
Choice 2: The type of insulation material
You can choose from various options for cavity wall insulation. Each type of insulation material has its own advantages. Rock wool and glass wool, for example, are more fireproof and have a better sound-absorbing effect compared to other insulation materials. The most important advantage of insulating granules is that they can be used with different façades and they have a very durable character. We’ve listed the average costs per type of insulation material:
|Type of insulation||Average cost price|
|Glass wool||About 9 dollars per 11 square feet|
|Rock wool||About 10 dollars per 11 square feet|
|Insulation pellets||About 11 dollars per 11 square feet|
|polyurethane foam||About 28 dollars per 11 square feet|
Choice 3: Combination of various insulation types
A house doesn’t only consist of a cavity wall that needs to be insulated. Different parts of a house that are not insulated can therefore be responsible for a considerable amount of heat loss. If you want to do something about this, you can insulate the different parts of your house in one go. This means that you’ll have to pay a large amount of money at once, but you’ll notice that in the long run it always turns out to be the best investment. By having several parts of your house insulated at the same time, the total price is reduced considerably.
Choice 4: Extra options for cavity wall insulation
You can always have extra work carried out on cavity wall insulation. We have also collected these different options for you and put them in an overview.
|Type of option||Average cost|
|Impregnation of the facade||About 930 dollars per facade|
|Installation of ventilation grilles||Between 20 & 70 dollar each|
|Central heating||About 6,800 dollars (incl. radiators)|
