Insulate Magazine Issue 11 - October 2017

When is an Insulation Manufacturer not and Insulation Manufacturer headlines the October issue of Insulate Magazine. Possibly the best front cover for an Insulation publication EVER.

The only independent insulation industry trade magazine Insulate Magazine Working to the Right Standard(s) U-values are an integral part of everyday life for the construction industry. Sometimes the success of a project can hinge entirely on hitting the thermal targets for the building’s envelope. By extension, that magnifies the importance of proving a specification’s ability to meet its target - and being able to trust in the answer provided. By Insulate Magazine. Which is where U-value calculations come in: all-important pieces of paper providing the required proof. There are many and various standards relating to calculations, so for the purposes of providing an overview we’ve used those listed by the British Board of Agrément (BBA) as applicable to their ‘Scheme for U-value Calculation Competency’ as a framework. ISO 6946 For all that this international standard might be seen as defining how the majority of U-value calculations are done, it is actually surprisingly narrow in its scope. The document’s own text limits itself to walls and roofs! Nevertheless, it forms the basis for many of the calculations that insulation manufacturers and energy assessment professionals produce, supplemented by a variety of other guidance that we’ll come to shortly. Known as the ‘combined method’, ISO 6946 describes a simplified tool capable of establishing the performance of constructions for the purposes of comparison, or helping determine compliance with thermal regulation targets. A detailed calculation method is also referred to, defined in ISO 10211. Numerical modelling carried out to that standard uses specialist software and tends not to be a widely-offered service, so we’re not going to cover it in detail here. However, when the majority of calculations are done the ‘simplified’ way, it is easy to forget there are alternative, more complex methods which provide additional data such as minimum surface temperatures. Obtaining a calculation done using the combined method is relatively straightforward - but that isn’t to say it is always the most appropriate method. 23 www.insulatenetwork.com 23
