The aim of this report is to give a concise description of curtain walls, what it is and why they are used. It is also a description of six different but commonly used design technologies. By giving a detailed description of the different types and there special properties, the pros and cons will be clarified. The three most interesting alternatives were selected to be included in a test, to show the best alternative from a certain point of view.

The parameters are:

• Environment

• Cost

• Ergonomics

• Isolation against noise and fire

• Durability

These are important parameters in the planning and design phase. The report contains a summary about each parameter and what is important to pay attention to during construction work.

The test is based on these parameters and by allotting points to each wall according to properties, for each parameter a best choice can be pointed out.

The report ends up with a discussion about the result and what are the most important properties. The end result shows the points per parameter for each wall.
