Glazing design consultancy – a supplier checklist

September 13, 2021


The ideal glazing specification should represent the best combination of product, performance, compliance and budget. Achieving this ideal, however, demands specific expertise especially when specifying high performance windows. A specification which is too broad could compromise architectural intent (if adjustments are required), and run the risk of possible non-compliance and associated budget overruns. It’s therefore vital that glazing products are backed by expert support, and early consideration should be given to check that your potential supplier can offer the following:

  • Early engagement and long term support: A supplier should encourage early stage discussions in order to identify, as soon as possible, the windows and doors which can deliver design vision, and meet performance and budget targets. Proactive support should continue throughout the project, through to post-installation.

  • Façade-specific design: Window by window specification is essential to ensure compliance with standards such as Secured By Design, for example, or to support cleaning and ventilation strategies. This type of detailed planning further improves budget control and scheduling, and minimises the risk of non-compliance which can lead to costly and time-consuming remedial work.

  • Expert installation advice: As well as determining an overall installation strategy, your supplier should highlight any specialist installation requirements as early as possible. This will ensure appropriate structural support, installation equipment or site access is in place, and also that the impacts of these requirements on budget and timescales are understood in advance.

  • Technical design support:This should be offered from the pre-tender stage, and include services such as window interface detail development, structural calculations, and design drawing packages. This should be supported by ongoing post order design works, with dedicated Design Partners providing services which guarantee accurate  specifications together with all the calculations required for regulatory compliance.
