Rockwool Cavity Wall Insulation Problems

Rockwool Cavity Wall Insulation Problems

In recent years, home insulation has become a major talking point amongst property owners in the UK.  Debates range from what the best insulation is, to how efficient the insulation is at conserving energy.

But just as there are positive talking points about insulation, there are also negative ones.

The North West of England alone, has more than a thousand homes that are facing a cavity wall insulation crisis. This isn’t because they don’t have insulation, but because they have the wrong type of insulation installed.

Cavity wall insulation is not for every home, and more so than almost any other part of a home, careful consideration needs to be put into the material that the insulation is made from.

In itself, cavity wall insulation is a wonderful investment, just like solid wall insulation. It is designed to help protect a home from excessive heat loss.

The right insulation will send your heating bills plummeting, but the wrong insulation could see you with major bills for damages.

Just as it is important to look at the positives of insulation, it is essential to look at the negatives, starting with the common rockwool cavity wall insulation problems. But also, importantly, why they happen and how they can be avoided, as the following article reveals…

What Is Rockwool Cavity Wall Insulation?

Rockwool cavity wall insulation is an incredibly interesting form of home insulation material, one of the most unique on the market. While not the most modern, and in many ways not the most efficient, it has some great properties that are very able to benefit your home.

The material is created primarily from molten rock than has been brought to temperatures of higher than 1500 degrees. Once it has been heated, the material is spun to create tiny fibres, before being combined with oil and a specialist binder.

Like other forms of traditional insulation, it is then blown into a cavity wall, forming a good seal. While the product is essentially quite effective, that doesn’t mean that it isn’t susceptible to some pretty serious rockwool cavity wall insulation problems as well.

Rockwool Cavity Wall Insulation Problems

Almost all rockwool cavity wall insulation problems can be traced back to the installation. Whether installed as a D.I.Y job, or with an inexperienced company, poorly fitted insulation opens the door to all manner of problems

What Problems Could I Encounter With Rockwool?

Rockwool cavity wall insulation problems come in all shapes and sizes, but if they occur, the problems generally only come in one size: large.

To help you understand what you should be looking for, we have put together a list of some of the rockwool cavity wall insulation problems that can occur, and possible reasons as to why:

Problem No. 1: The Building Regulations Haven’t Been Abided By:

The cavity wall building regulations are in place for a reason, if these aren’t followed, some major problems can occur in the short and long term.

Problem No. 2: There Has Been a Dry Slump:

Dry slump is a problem that primarily affects blown in fibre insulation. While the aim is to fill the area between walls, once the insulation has settled, it can ‘slump’. This causes a cold spot to form at the top of a wall, allowing condensation and mould to form on the interior walls of a property.

Problem No. 3: There Has Been a Wet Slump:

Similar to dry slump, wet slump occurs when the materials get wet. This pushes the insulation down, exposing a massive proportion of a wall to the elements, possibly causing major damage.

Problem No. 4: The Wall Has Driving Rain:

One of insulations’ major foes is driving rain, rain that is able to easily penetrate a wall. Properties with walls hit by driving rain, can have serious issues with damp and ineffective insulation.

Problem No. 5: Old Insulation Was Not Removed Properly:

Not removing old insulation properly can result in poorly finished new insulation. Damp or compromised insulation mixing with fresh rockwool insulation will create an area that is very prone to problems.

Problem No. 6: Installation Was Poor or Incorrect:

Almost all rockwool cavity wall insulation problems can be traced back to the installation. Whether installed as a D.I.Y job, or with an inexperienced company, poorly fitted insulation opens the door to all manner of problems.

Rockwool Cavity Wall Insulation Problems

For some homes, alternative products, like modern spray foam insulation, are a much better option to blown in insulation. The material is moisture resistant, and expands to fit a cavity wall, severely reducing the chances of one of the most common rockwool cavity wall insulation problems, dry slump, from occurring

Rockwool Cavity Wall Insulation Problems: How To Prevent Them

Insulation is essential in modern and older homes, it makes a space warmer, reduces energy consumption, and soundproofs a property, to name just a few benefits. However, it also must be suitable for a property, and, more importantly, installed correctly.

Comparing the market before investing, and seeing what previous cavity wall insulation customers have to say about the products they have purchased, is essential.

For some homes, alternative products, like modern spray foam insulation, are a much better option to blown in insulation. The material is moisture resistant, and expands to fit a cavity wall, severely reducing the chances of one of the most common rockwool cavity wall insulation problems, dry slump, from occurring.
