Insulation and waterproofing COVERS COMMUNITIESISOLATION FLAT ROOFS INVERTED
Traditionally, the treatment given to the decks of the communities was to provide them with a good layer of waterproofing to avoid water seepage into housing community located immediately below deck. Currently, thermal insulation covers has become a fundamental requirement, contained in the Technical Building Code (CTE), as a means of achieving energy efficient communities Aislamiento TÃ©rmico so insulation and waterproofing must be present on the covers of communities of owners.
One of the best solutions for insulation and waterproofing covers communities are inverted flat roofs in which the insulation material lies above the waterproofing material.
The wide variety of insulating materials that can be used in the isolation of the communities covered, the extruded polystyrene (XPS), is the most appropriate for the case of inverted roof. The characteristics that determine the choice of extruded polystyrene (XPS) as insulating material of choice in the case of inverted roofs are: resistance to water absorption by immersion and vapor diffusion, retaining its thermal and mechanical properties in contact with both long-term water immersion and after freeze-thaw cycles, maintaining the mechanical strength after freeze-thaw cycles, so that the compression strength is not reduced by more than 10, a structure of Closed cell which prevents the passage of water from one cell to another so that its capillarity is null and be highly resistant to putrefaction material.
The isolation of inverted roofs in communities of owners avoids many of the problems of traditional covers, such as: premature aging and deterioration of community housing due to thermal shock both daily and seasonal, mechanical damage, degradation due to ultraviolet radiation and moisture trapped under the waterproofing, from rain during installation of the humidity of building materials, or interstitial condensation.
But also the thermal insulation of inverted roofs, has other advantages such as the ability to be installed in all weather conditions, speed and simplicity of installation, easy access to the waterproofing layer in case he had to be repaired, reduced maintenance needs and the ability to take multiple finishes.
