Water insulation (Waterproofing)
Many people talk about terraced roof insulation, but they mean terraced roof water insulation, or else waterproofing. They are actually two quite different concepts, equally useful but in different cases. When we want protection from temperature – that is, our house to remain cool in summer and warm in winter – then we need thermal insulation (not terraced roof water insulation or waterproofing), whereas, when the problem has to do with humidity (water running), then probably terraced roof waterproofing is needed.
Do not confuse them and, most importantly, pay attention to what each workman or company means by the term ‘insulation’!
Many times we have got humidity problems and we think that terraced roof waterproofing is the solution, but sometimes (depending on the causes that create humidity) the solution lies only in thermal insulation.
Terraced roof waterproofing is not enough when there is the phenomenon of liquefaction (due to condensation of steam to water). This means that, when there is a great difference between the temperature in the interior of the house and the temperature of the surroundings, steam is created. This is accumulated on the ceiling, which results in the gradual formation of humidity. It is easily understood that in this case the problem does not have to do with water leaking from the terraced roof to the interior, but with temperature difference. Consequently, only a complete terraced roof thermal insulation will solve the problem.
In case you need something like this, the most effective and economically accessible option is the light thermal insulation and waterproofing of terraced roofs.
