Air leaks in the rafters of the Federal Minister

Need for air-tightness level, rafters

per Code of insulation in roof and wall - - published by the National Federation of Roofing Trades Association of roof, wall, and sealing technology in September 2004, the following requirements apply:

3.2. Diffusion

3.2.1 General
(1) may not occur by diffusion in the thermally insulated to a harmful component of condensate in the risk by increasing the moisture content of the insulation and the stability of structural design or to pest infestation out.
(2) Evidence that diffusion does not result in damaging condensate water occurs by diffusion calculation according to DIN 4108-3. In this mathematical proof may be waived as provided in Sections 3.2.2 and 3.2.3 requirements.

3.2.2 roofs
(...)
(3) For the following non-ventilated roofs may be no need for a mathematical proof:
a) Non-ventilated roofs with roofing
(...)
- Non-ventilated roofs non-ventilated roof covering and roof covering a space side and a room-side vapor barrier sd, i ≥ 100 m below the insulation layer.
(4) The effectiveness of non-ventilated, insulated roofs with a vapor barrier with a sd, i \u0026lt;100 m and diffusion-proof layer on the outside can be detected. Thereof should be made in the outer layers with sd egg ≥ 100 m only in exceptional cases, as trapped moisture may have penetrated or later, for example, structural moisture through leaks or increased only poorly or not at all dry.

The connections of the room-side vapor barrier in accordance with the requirements of DIN 4108 Part 3 out professionally.

what must be considered in the final acceptance

What is in building law and contract law respects the loss? It is a turning point in the construction activities.


first With the decline in the construction period ends, so it is therefore also
a completion message.

second With the decrease in the risk passes to the owners of the
result, the burden of proof reverses. (see VOB / B
§ 12 paragraph 6). This means after collection, the building owner, for
not listed in the acceptance report defects and hidden
; prove defects, who caused a specific defect.

third With the decline in the period of limitation of warranty,
means after the acceptance of any defects
warranty defects before it was fulfillment of deficiencies.

The limitation period is interrupted

a) VOB contracts by detectable defects in writing within the period

b) BGB contracts by court order, request for judicial
evidence or action is brought within the time limit

4th From the decrease leitet sich eine Zahlungsverpflichtung entsprechend
    der vertraglichen Vereinbarungen ab.


5. Die Abnahme ist reglementiert:

    a) Im BGB - der Kaufsache § 433/448 - des Werkes § 640/646

    b) in der VOB/B § 12


6. Besonderheiten:

    Zu unterscheiden sind die

- notional acceptance by putting / Inbenutzungnahme
VOB / B § 12 No. 5 / 1

- already known defects

- Penalty if agreed

The decrease is a unilateral declaration of the owner if the contractor

Causes insulation thick air?

The answer is: No! But still, even in expert circles, holds the mistaken belief that a house with modern insulation can not breathe. That's not true! For a building wall - Whether with or without thermal insulation - must be air tight even (DIN 4108) Thermal insulation in buildings). Only 2 percent of the air escape through the wall. against poor air quality that is is only one thing: air. Just
enmal two percent of the air humidity can diffuse across the wall. The remaining 98 percent must be paid via the ventilation behavior.
According to DIN 4108, it even aim that a wall is air tight .. For each leakage means that the heat and is thus lost the power over the walls. At today's energy prices can be, but no longer afford to heat the neighborhood.
The Construction Technology has indeed in recent decades changed - we use our behavior, however, often not. High energy costs tempt little heat, and revealed, is rarely still, because you do not want the insulated warm house to cool down. Previously window or roof trusses were still many "loopholes" through which the wind whistled at times. Here was an unwanted circulation, due to the current energy prices do no one can or wants more.
