SZ-03 Vapour control and services

Code: SZ-03 · Version: 1 · Issued: 2026-10

Rules

1. No services through the profiles. For fire protection, and because the membrane alone is the vapour barrier.
2. Services run on battens on the membrane’s inner side — on a wall that costs 3–4 cm.
3. The membrane is not drilled. Where a penetration is unavoidable, it is sealed as the drawing specifies.

Background: LGS build-ups.

In preparation

This article is part of the structure; its content comes in the next round. It will cover:

• membrane laps and junctions
• sealing penetrations: boxes, pipes
• wet rooms
