-===== BASIC RULES FOR A GOOD LEVEL OF AIRTIGHTNESS =====
+===== Basic rules for a good level of airtightness=====
 An important **basic rule** applies for airtightness that must generally be observed: there must always be __one single__ airtight layer. Two partly airtight layers do not lead to the required result and are generally more complicated and expensive. For example, a conventional ‘vestibule door’ behind the non-airtight front door will not lead to an adequate level of airtightness of the building. Imagine a leaky bucket that is placed in another leaky bucket: water continues to leak out (water corresponding to air). It is therefore not advisable for example, to consider the internal plaster as an airtight layer if weak points exist here (e.g. inaccessible wood beam ceilings without plaster on the masonry in this area).
