Remember last week our frozen water pipe? In the end I placed mineral wool between the facade and the inner wall. Easy to say, but readers want to know more about isolation.
Today, insulation is the norm, but why? In most places in the world, the sun is not enough to make heating in the house unnecessary. In an uninsulated home, 75% of our energy consumption is spent on heating. In winter there is also a greater heat transport through walls, roof, floor, windows and other openings from the inside to the outside than in the summer. We insulate to supplement this loss, but also to limit heating costs and CO2 emissions.
Mud and straw
In the Middle Ages, mud and straw were used to plug holes in the walls to keep the cold out and the warmth of the wood fire in. Until the 17th century, mainly natural products such as moss, straw and hemp were used. These were highly flammable.
From the 17th century on, people started to experiment with so-called cavity walls. You actually put two walls with space in between next to each other; the stagnant air in between provides insulation. Until the 19th century, this method was still limited to certain areas, for example only the living room. With the emergence of industry, more and more insulating materials were added, which at that time were already being used in cavity walls and between floors and roofs.
Since the Second World War, we only really started to concern ourselves with insulating the entire house. Glass wool conquered the market because it has far fewer drawbacks than traditional means. Nowadays, it is precisely natural insulating materials such as straw and sheep’s wool, which have been treated in such a way that the fire hazard has passed, and are on the rise again. Upcycling of materials to insulation is also frequently used, such as old newspapers.
Traditional insulation materials are often not resistant to moisture and must therefore be protected with foils. These in turn ensure that the humidity in the home rises, which gives you a negative effect. Because to heat moist air, you need more energy. So I always say: insulation is ventilation. Obviously with a heat recovery unit, a HRV.
I insulated our wall with a piece of mineral wool. The exterior paneling was already provided with a vapor-open foil. Then I applied rock wool between the framework with a damp-proof foil over it so that no moisture can penetrate. Most insulation materials work on the principle of stagnant air. Moisture has an adverse effect on this function and the life span. We were lucky; our water pipe was not cracked from the freezing. On my YouTube channel Mulder Maakt I show you how to repair a water pipe.
