Typically, in curtain-wall installations, the Contractor will install units on clips attached to the main structure. These clips are typically aluminum and our structure is typically steel or concrete, both structure materials need to be separated from the aluminum curtain wall system.


Storefront and Curtainwall Tolerances

When designing the building envelope, we need to take into account the constructability and tolerance of the materials, components, and systems. Each material has a tolerance from material fabrication, component installation, as well as system installation tolerance. There are more tolerance allowances indicated in the referenced standards.
