In the field of conservation and consolidation of historic and architectural buildings, great importance is placed on interventions and materials which, in addition to being extremely strong, reliable and safe, are also lightweight, compatible, reversible and non-invasive, in compliance with the structure to which they will be applied. This requirement has resulted in the creation of P-TREX pultruded profiles, used for structural reinforcement, retrofitting and the improvement of seismic performance of historic buildings, as well as the creation of new structures, both temporary and permanent.
