There are a number of good energy renovations you can make relatively easily at your house. One of them is cavity wall insulation . But how do you find out if you even have a house with a cavern wall? This is necessarily a requirement in order to carry out this type of energy renovation. Before you search the web for an expert who can help you with this, it is worth trying to research this yourself. It is easy and easy to do some basic tests and measurements even without problems.

Let's delve into what options you have as a homeowner yourself to investigate whether you have a cavity wall and whether it can be wall insulated, or whether there is already a cavity insulation between the walls.

If you are in possession of the drawings of the house, you should, through reading these, be able to indicate whether there is a cavity between the inner and outer walls, as well as how large this cavity is. Now it is not true that everyone has the drawings on his house, and of course it is not a solution that can be used.

If your outer wall is walled you can also try measuring the thickness of this wall. A good mark is that if it is thicker than 24 cm, you most likely have a cavity. This is because a brick in the front and back wall will only be about 21 cm together, leaving a void in the middle. This small measurement also gives you an idea of how much effect you can get from any cavity wall insulation. A rule of thumb is that the thicker the outer wall, the greater the distance between the walls and therefore there is also room for more cavity wall insulation. It goes without saying that the more insulation you can squeeze in, the greater the effect it will have.

Another method of measuring some problems is to drill through the wall. That way you can measure the distance to the outer wall and find out how big a cavity you have. This method also has another advantage, namely that you are assured that cavity walls are already insulated. When you drill through the inner wall and find out that there is a cavity, it will, depending on the condition, be to see if there is insulation material in your cavity.

All of this, of course, is preliminary research to give an insight into whether there is any breeding ground for such a cavity wall insulation. If so, you should get hold of some professionals can examine your house to the bottom. This can be done for example with a heat sensitive camera.   Such a camera can photograph your entire house, giving a clear picture of where the heat is escaping from the house and whether cavity wall insulation is needed at all. However, this tool requires there is a minimum of 12 degrees difference between inside and outside temperature, so it should not be made a high summer day when the sun is setting. This is easily done in the spring or in the winter. So it takes a little planning before you get started, but otherwise it is quite easy intervention.
