In response to rising energy costs, the government announced plans to accelerate the installation of adiabatic walls. In particular, all homeowners over the age of 70 years free of charge provide insulation of the cavity wall (Spouwmuurisolatie).
This led to a significant increase in the number of letters and letters that I received on this issue. I am skeptical of the desirability of blowing insulation into the existing walls of the cavity – it is based on my own experience, like a trained mason, as a university architecture teacher, and recently as a columnist for the Sunday Telegraph. Position.
In most letters a simple question arises. They said that the cost of heating is a record, which is a huge burden for people with a fixed income, especially for pensioners. Should they use the insulation on the walls from the cavity of emptiness?
I can not make this decision for anyone. All I can do is provide readers with information and make informed decisions for themselves. So, these are the facts.

Wallboard destroys the house meter

Material of insulating material
The nineteenth-century West Coast, exhibited in the United Kingdom and Ireland, introduced a wall of masonry to prevent wind and rain from penetrating the inner surface. They gradually spread to other parts of the country, because it was discovered that the air layer in the cavity provides a certain degree of thermal insulation. Since 1945, the use of light blocks instead of bricks has strengthened the internal blades of the wall, thereby improving the quality of insulation. However, the main reason for the construction of hollow walls has always been the prevention of rain.
Since the 1980s, construction regulations required the construction of new houses in premises with insulation materials. While they are properly designed, this insulation should not affect the resistance of the wall to the penetration of rain.
In most cases, the insulation is attached to the inner blade, leaving a narrow cavity to intercept any rain that penetrates the outer tile. Such an insulating material is generally used for a rigid foam board with a waterproof or semi-rigid mineral wool or fiberglass “shale” in essentially the same way as the fibers are arranged vertically, so that any penetration of rainwater must be discharged downward, The possibility penetrates into the internal leaves. This is important because construction and research institutions have discovered that single-layer brick walls always flow during storms. Leakage occurs with vertical (or “peel”) seams between adjacent slabs due to shrinkage drying in the mortar. This is not a bad manufacturing problem, it is an inevitable attribute of this architectural form.
For example, many readers with single-door garages report on their walls at home, complaining that rain will penetrate from outside when the rain is raining, causing a puddle on the garage floor. Thus, if rainwater penetrate into their garage walls, their living room and bedroom brick exterior layer of the same situation will occur, but until the cave is kept clean, water should flow inside the brick at the foundation level, there will never be a Note. Only a period before the recent period of the cavity walls appear isolation measures, rainwater infiltration The only problem is that the steel wall mortar joint is dirty with feces and / or itself blocked from the outside to the inside of the leaf leaves downwards or cavities Low level of excrement mortar or other waste. In these cases, caves penetrating the rain can pass through the cave and look like wet spots on the inner decorative surface, but the solution is relatively simple – cut a few bricks and remove debris from the hole or replace the forbidden strip.
The humidity problem caused by the cavity wall insulation
Until recently, because of the construction of new insulating materials, the humidity problems caused by the insulation of the house, as a rule, have not yet occurred, although this situation is changing now, and the humidity caused by the built-in cavities appeared for the first time and I will return later. To this topic.
