A Free Lunch, The language of Insulation, Artificial Intelligence and Insulation, and in-depth review of Ecobuild 2018 feature amongst articles from the BBA, NIA, Kingspan, IMA, Sto and more feature in this months edition what the product is, its technical performance, how it complies with Building Regulations and where it can be used. Insulation manufacturers work hard to produce the best product for each specific application, to ensure that all the necessary requirements are met. Obviously, for an insulation the key element is thermal performance, so the correct installation of any insulation is absolutely essential. If it is installed poorly or incorrectly, there will be a loss of thermal performance and, with the majority of insulation ending up covered once it is installed, this reduced performance will continue throughout its life, and may even cause issues at a later date. Correct installation of insulation was one of the many parameters picked up in the Zero Carbon Hub Performance Gap report as an area to improve (see Building Control Journal February/March, pp.14–15). Architects, designers and specifiers are required to take CPD to keep abreast of developments. However, an installer may often only attend a one-day training course and become approved with typically very little follow-up or auditing, even though he/she may then be considered the company expert. So the focus for manufacturers to increase market share must be in preparing comprehensive technical literature to complement the sales material, as well as detailed installation guidance to demonstrate the ease of fitting all the key features and benefits. This guidance can range from images of the installation process right through to on-site training schemes. Companies are keen to ensure that their product is installed correctly, does what it should do and stands the test of time. So, if reflective insulation uses the standard principles of physics for thermal performance and has been around for the past 60 years or so, used as it was during the great space race of the 1950’s and 60’s, being both thin and lightweight, then you could ask the question – why is it not used in more applications? The lack of a current European Product Standard may be one of the reasons why architects, specifiers and contractors continue to use their normal insulant, given that this has worked in the past and they do not have time to investigate all the possibilities. This is where a BBA Certificate gives the manufacturer the ability to go out into the market place to support and solve many of the questions that industry has regarding product performance. With regulated building requirements for U-values getting lower and lower, the use of reflective insulation in conjunction with other traditional insulants can help achieve these increasingly stringent targets. To achieve maximum performance, products must be used in conjunction with an air cavity in front of, and in some cases behind, the insulation. Some products are also classed as a vapour control layer because they offer a high degree of moisture resistance and, of course, must be used on the warm side of any proposed system to reduce the risk of any interstitial condensation. Others are classed as breathable because they are perforated through all layers to allow any moisture build-up to pass through the material and dissipate on the other side, typically in the form of a ventilated cavity in a warm pitched roof. Although it may not have been a smooth or easy ride to get here, reflective insulation is now definitely making significant inroads into the European insulant market. The BBA’s auditing and inspection team has a huge wealth of knowledge and experience of the whole spectrum of on-site insulation installations, from the very best to the very worst, so it can offer a valuable resource for those looking to ensure that the product is installed correctly.
