Long-Term Behaviour of Cavity-Insulated Masonry
There are as yet no official test results concerning the long term effect of water-resisting chemicals on cavity-insulating materials or on the danger to wall-ties through corrosion due the addition of insulation. Intention of the investigation: If a wall cavity is filled with insulating material, this improves the insulation of the wall and is a good way of reducing energy costs. This investigation is concerned with the question of the longterm behaviour of water-resistant cavity-insulating materials and as to whether there is any danger of corrosion of the wall ties. The long-term behaviour of various insulating materials was investigated by way of laboratory tests and on test-walls subjected to artificial rain as well as on other test walls subjected to natural precipitation. In order that the corrosion behaviour could be evaluated, test were carried out in the laboratory and in the open air using various kinds of wall-ties. Depending on the type of insulation used, varying extents of deterioration were discovered in the water-resistance of certain insulating materials. As a result of this examination a test method was developed for the durability of the water-resistance of cavity-insulating materials. It was discovered that insulating material only has a limited influence on the corrosion of wall ties. It is not always possible to add insulation to a cavity wall without taking certain precautions.
