Q

Explain vapour diffusion?

A

Typical example - vapour diffusion happens when a material - i.e gypsum drywall installed on a wall - seperates two zone. If the air on on side of the drywall is very damp, and the air on the other side of the drywall is very dry, moisture in the air will diffuse through the drywall.

If the drywall is screwed to a stud wall that separates a damp area from a dry area, the drywall absorbs moisture on its damp side. Moisture evaporates from its dry side. The moisture has moved through the drywall by diffusion.

25
Q

Benefit of vapour diffusion?

A

Vapour diffusion typically thought of as a negative phenomenon - one that needs to be completely stopped.

In reality, a positive mechanism that can be used to a designers benefit, and is very important drying mechanism for an enclosure assembly.

In fact, vapour diffusion is the only process through which the interiors of most in-service wall assembiles can dry.

26
Q

What is a Producer Statement?

A
  • A professional opinion based on sound judgment and specialist expertise, intended to provide BCAs with reasonable grounds for the issue of a Building Consent or a Code Compliance Certificate, without having to duplicate design or construction checking undertaken by others.
  • A statement that certain work will be, or has been, carried out in accordance with certain technical specifications.
  • Typically used for specialist work, such as engineering, or a proprietary product which is installed by appointed contractors.
  • It is not a product warranty or guarantee of compliance.
