FLAT ROOFING & WATERPROOFING SYSTEMS Calculated benefits For roofing contractors installing Firestone’s RubberGard EPDM membranes, amongst the most valuable technical support services we offer is assistance with thermal, condensation and wind loading calculations. Combining the expertise of our technical team, computer modelled data and design and specification information about the building (including the legacy substrate and roof condition for overlay refurbishment projects) our calculations underpin the performance of the installed system and support decision-making from the contractor team. For example, our technical team is able to advise on whether a mechanically fixed or fully-adhered system will work best for a particular project, in the context of the building design and location, factoring in elements including the substrate and roof build up, local climate and wind conditions, noise, odour and space restrictions, length of programme and available budget. Accurate wind load calculations not only ensure the integrity and service life of the finished system but can also be vital in helping to avoid the possibility of wind uplift, which could damage the installation post completion. Technical support can also be vital in ensuring the right roof build up, with recommendations for vapour control and insulation forming an important element of the building’s thermal performance and resistance to condensation. Final inspection For the contractor’s peace of mind and the developer / end user’s guarantee of performance, the system supplier should also carry out a final inspection of the finished installation to check that every element of the job has been undertaken in line with the specification, the client’s requirements and the manufacturer’s installation guidelines. If the technical support has been consistent throughout the scheme, including both specification and site input, this should be little more than a formality and an endorsement of a job well done. www.firestonebpe.co.uk Above: A site survey by the roofing supplier’s technical team is vital for developing the right specification for a refurbishment project Above: Core sampling by the roofing supplier provides vital information about the existing roof build up to determine its viability and ensure an effective specification
