Building envelope

We have a public liability and property damage expertise in any building envelope related damage : insulation, watertightness, thermal and acoustic comfort, air quality…

We identify the technical causes of the damages in order to determine any liability incurred, to point out any possible legal recourse and to assist our customers in resolving their high-stakes issues. Several different fields of expertise are needed to identify accident-related pathologies : glass engineering, strength of materials, soil mechanics, construction (frameworks and structures, coverings, claddings).

Main areas of expertise

  • Glazing : annealing, tempered or insulated glass breakage, mechanical fastener trouble, structural glazing, delamination of laminated glass, misting up of insulated glazing in equilibrium of pressure, pollution and deterioration of the optical qualities of reflective glass (clear or frosted) ;
  • Aluminum, Steel, Timber, PVC Windows and doors : watertightness or airtightness defect, windows or heavy doors hardware dysfunction, warping or breakage caused by frame movements ;
  • Facades, Glass walling, Curtain walls and Cladding : non-watertightness and airtightness, bad mechanical resistance, metal cladding issue, coating blisters, issues and serial damages on cladding and covering ;
  • Watertightness : roofing and terrace leaks (designing and/or manufacturing defect, accidental perforation, plantation), metal framed glass roof leak, building infrastructure seepage caused by leaky tanking.

More and more sophisticated and innovative techniques are used in building envelopes, which result in increasingly complex damages. CPA Experts’ engineers assess these damages before developing solutions and tailor-made tools that facilitate the expertise and allow our customers to keep the repair costs as low as possible.
