Fixings for EWI

Mechanical fixings or anchors play an important function in the way in which External Wall Insulation Systems perform
under building and dynamic loadings. The role of the fixing is far greater than simply holding the insulation in place
until the render is applied, it has to accommodate movement within the structure, positive and negative wind pressure
and supporting the self-weight of the system to name a few key functions.
