Table notes: Design service life for all components is 60 years. In practice, service lives greatly in excess of this are achievable; shorter lives have been the result of not following good practice guidance in design and installation. Capital costs are based on the average and include the cladding, breather membrane and support system if required. A nominal allowance for detailing, junctions and movement joints is included. Insulation and wall structure are excluded. In use costs include nominal amounts for cleaning, repointing or regrouting where applicable and minor repairs. A discount rate of 3.5% is used to calculate net present values. A cost analysis based on project specific information is essential for a realistic best value appraisal.
