Ventilated facade design guide
A practical engineering guide to rainscreen facades for architects, engineers and contractors working in Georgia.
This guide is for architects, structural engineers, developers and contractors who need to understand a ventilated facade well enough to specify it, review it or build it in Georgia. It is written by designers who work on rainscreen facades, and it uses the Georgian regulations where they exist and says plainly where they do not. Georgia has no standard dedicated to ventilated facades, so the engineering argument in the project matters more than a citation.
How the guide is organised
- The system. How a ventilated facade works, the air gap, brackets and subframe profiles and alloys.
- Fixing and details. Anchors and substrates, junctions, movement joints and facade thickness.
- Life of the facade. Durability, installation sequence and quality control.
- Pitfalls and money. Typical mistakes of designers and installers, including those specific to Georgian rules, and the cost drivers per square metre.
Each article answers one practical question, gives dimensions and checklists where they are useful, and links to the relevant regulation.
Where to start
- If you are new to the topic, read how a ventilated facade works first, then the air gap.
- If you are reviewing a design, go to the checklists in the articles on the air gap, brackets and subframe, and compare them with the drawings.
- If you need the legal frame, see Georgian regulations; for what a design package contains, see facade design.
The guide gives general engineering guidance. The values for a particular building come from its own calculation, so send us the drawings if you want one.
