Increasingly, the designer wants to achieve a slim roof package, making it different from the traditional structure with a relatively high ventilated cavity. Also, with the renovation of roofs, the thickness of the total package can be a problem. The choice is on a non-ventilated, vapor-tight system with the advantage of a slimmer design.<\/p>\n
What is a non-ventilated structure?<\/p>\n
A non-ventilated structure is a roof and fa\u00e7ade construction with no ventilation or air cavity. Thermal insulation followed by a roof covering system is fitted to the support structure. This produces a single-layer, non-ventilated structure. This concept is highly suited to sloping roofs and fa\u00e7ades with zinc. To avoid the formation of condensation the structure must be damp proofed. Internal condensation or condensation resulting from nocturnal temperature drops, do not form in this construction either. This represents a major difference with a traditional cold roof system. When building this structure the preference is for a damp-proof system with a \u03bc.d (or Sd) value of at least 150 meters.[\/vc_column_text][mk_padding_divider size=”10″][vc_single_image image=”35449″ img_size=”full” alignment=”center”][mk_padding_divider size=”10″][\/vc_column][\/vc_row][vc_row][vc_column][mk_padding_divider][\/vc_column][\/vc_row][vc_row el_class=”rij-wit-schaduw”][vc_column][mk_padding_divider][vc_column_text css=”.vc_custom_1560937536616{margin-bottom: 0px !important;}”]Benefits of a vapor-tight construction
\n\u2022 Considerably more design freedom for architects and developers
\n\u2022 A slim design, because no ventilation cavity is needed
\n\u2022 Easy to handle and therefore time saving during assembly
\n\u2022 High-quality noise damping and insulation
\n\u2022 The roof or fa\u00e7ade construction is immediately rain-proof, which reduces construction time<\/p>\n
Risks of a vapor-tight construction
\nIn the application of vapor-proof systems, risks are present that may affect the functionality and longevity:
\n\u2022 Mutual seams that are not properly taped
\n\u2022 No rigid substructures
\n\u2022 Making penetrations at a later time, which can cause leaks
\n\u2022 Leaks that may occur through careless installation and detail mistakes[\/vc_column_text][mk_padding_divider size=”20″][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"
