Thermal insulation and energy economy in buildings - Part 7: Air tightness of buildings - Requirements, recommendations and examples for planning and construction
Wärmeschutz und Energie-Einsparung in Gebäuden - Teil 7: Luftdichtheit von Gebäuden - Anforderungen, Planungs- und Ausführungsempfehlungen sowie -beispiele
Overview
This standard specifies requirements for compliance with airtightness. It provides recommendations for planning and implementation and shows examples of implementation, including suitable building products, which enable the realization of permanent airtightness of heated or air-conditioned buildings and parts of buildings. To distinguish airtightness from wind tightness, which is not the subject of this document, the terms in Clause 3 apply. The design examples do not deal with functional joints and openings in the heat-transferring enclosing surface, such as closing joints of doors and windows, belt penetrations in roller shutter boxes and letterboxes. Only principle sketches and example sketches are shown. They do not represent detailed drawings ready for implementation or other construction/building physics issues. Other solutions are permissible if the principle of airtightness is observed. This document has been prepared by Working Committee NA 005-56-93 AA "Luftdichtheit (SpA zu CEN/TC 89/WG 15 und ISO/TC 163/SC 1/WG 10)" ("Airtightness (mirror committee for CEN/TC 89/WG 15 und ISO/TC 163/SC 1/WG 10)") at DIN Standards Committee Building and Civil Engineering (NABau).
