FIRE RISK FOCUS FOR LANGLEY
Langley Waterproofing Systems has invested further in British Board of Agrément (BBA) independent assessment.
Additional comprehensive, independent testing and assessment of its BBA certified systems further endorses the fire performance of
Langley’s RBM range. It certifies that its TA-20, TA-25 and TA-30 Flat Roofing Systems meet Broof(t4), the highest fire testing
classification under the European standard system. The BBA certificates further detail the performance with regard to specific factors
such as durability, thermal performance, wind up-lift and resistance to mechanical damage. The external fire performance of each Langley TA Flat Roofing System has
been rigorously tested and certified with varying configurations of the system’s build-up. Langley’s TA Flat Roofing Systems have been thoroughly tested and certified
with PIR insulation thicknesses of 30mm to 250mm and Mineral Wool insulation thicknesses of 30mm to 150mm. They have additionally been tested on different roof
deck types including cement board and wood particle board. This means that Langley’s TA Flat Roofing Systems can be used in a range of different configurations to
best suit the requirements of the application, whilst ensuring full compliance with Broof(t4) fire rating to BS EN 13501-5:2005. Typically, systems are only tested in a
limited number of configurations and details are given on the system supplier’s BBA certification. The certificate then states that other specifications will require
separate testing and assessment on a case by case basis. It cannot be automatically assumed that the system will still perform to that standard with a different
combination of components. View Langley’s Whitepaper supported by Zurich UK here: https://www.langley.co.uk/fire-compliance-whitepaper

LIGHT WORK FOR TOUGH PROJECTS
BMI is setting new standards in lightweight metal tiles with the introduction of AeroDek.
AeroDek, the new lightweight metal tile solution from BMI
UK & Ireland is available in a choice of dimensions,
colours, popular profiles and steel grade, depending on
the tile.
AeroDek is said to be faster, safer, stronger and lighter than traditional roof coverings, while replicating
the high aesthetic of clay, concrete or slate in a tile guaranteed to last for 40 years. Made from a
recyclable, galvanised steel core protected by a resilient, multi-layer stone-coated finish, the interlocking
tiles are quick to install, lightweight and resistant to damage by vandalism or extreme weather. These
properties make AeroDek particularly suited to buildings that demand a robust and secure roof solution,
and projects that are subject to extreme weather conditions in coastal or aggressive climate
environments. Being durable, lightweight, low maintenance, fast to fix, AeroDek is also highly suitable for
flat-to-pitch conversions down to 10º, especially in the social and rented housing sectors. AeroDek’s
robustness, performance and security in the face of vandalism is demonstrated by its unique
accreditation under the Secured by Design crime prevention initiative, as well as by the Loss Prevention
Certification Board. The fully dry fixed roofing system ensures not only maximum storm resistance, but
also compliance with the installation requirements of BS 5534: 2014 +A2: 2018 Code of practice for
Slating and Tiling. BBA certified, the three tiles in the AeroDek range – Robust Plus, Traditional Plus and
Traditional Plus 0.9mm – typically weigh a seventh of traditional alternatives and represent a huge
materials saving, with an average 65m² roof requiring over 70% fewer tiles than the traditional
equivalents. www.bmigroup.com/uk
