Roof insulation is generally needed to prevent hot, cold and moisture from entering the building. Roof insulations are applications that prevent the building from sweating and dampening, while extending the life of the building. Insulation forms made in order to minimize the damages caused by rain and snow water accumulating on the roof in winter are related to the shape and location of the roof. At the same time, while trying to prevent the cold air from entering in the winter on the roofs where the thermal insulation is made, it is aimed to protect the building from the harmful and steep sun rays in the summer.
Waterproofing on Roofs
Roof insulations are generally made on roofs for three reasons and the application technique of each is different from each other. Membrane, plastomeric insulation covers, elostomeric insulation covers and under-tile insulation covers are the leading insulation systems applied to prevent the humidity and moss formation caused by the rain and snow in the winter in the building. These covers, which are mostly waterproof, are preferred because of their easy use and fast application. On the other hand, there are insulation forms that are realized by applying the roof waterproofing systems to the roof as liquid. These materials are bitumen based waterproofing materials, cement based roof waterproofing materials and polyurethane based insulation materials as well as acrylic based insulation materials.
Thermal Insulation on Roofs
Apart from waterproofing, thermal insulation processes are also carried out in roof insulation. Types of thermal insulation vary according to the shape of the roof. The most common types of roof thermal insulation today, apart from laying glass and rock wool, are Polystran and Polyurethane applications. Heat insulation materials applied to different types of roofs do not give out the heat, but prevent the cold air from entering. Thermal insulation systems balance the temperature inside the building and prevent the building from wearing down over time. The heat insulation application, which also prevents mold formation due to sweating in the building, also provides sound insulation. Thanks to the thermal insulation applications, 25% of the heat loss in the building is prevented.
Terrace Roof Insulation
Sometimes, since the roofs are in the form of terraces, the insulation systems take shape accordingly. In terrace roof insulation applications, heat and water insulation are generally applied in the same way. Tar paper, glass walk or ruberoid insulation material is placed on the reinforced concrete roof plate, after the terrace slope is given, the insulation materials in the form of plates are laid on the terrace where the leveling concrete is poured, and mastic concrete is applied on it.
