CLADDING & SHEETING specifically tested to these standards. Understanding that not all “flame retardant” products are equal necessitates understanding the different standards, different testing procedures and varying “pass” results for different countries. For example, to pass EN ISO 13501-1, the flame spread must not exceed 150mm within 60 seconds (when exposed to a flame for 30 seconds), which is more stringent than for BS 76 Part 7. UK Building Regulations also consider building height, occupancy and fire severity as determining factors. The highest ratings for flame retardancy are Class 1 (UK) and Euro Class B-s1,d0, both accepted testing standards in Approved Document B. But what is Class 0, listed in Building Regulations as the highest standard required? This is not a UK fire test rating, rather it is a classification specified in the Building Regulations. It means that the material is either non-burnable or achieved a Class 1 (BS 476 Part 7) result and a Class 1 (BS 476 Part 6) Index not more than 6 (after 90 seconds) and not more than 12 (after 20 minutes). Euro Class A1 and A2 are given to materials that are nonburnable products. See the table for an approximate guide to the different standards. Shared responsibility In her interim report, Dame Judith said: “I am convinced of the need for a new intelligent 048 FEBRUARY 2018 RCIMAG.COM Euro Fire Class System and UK Fire Class System system of regulation and enforcement for highrise and complex buildings, which will encourage everyone to do the right thing, and will hold to account those who try to cut corners.” Until that brave new world arrives, every manufacturer of flame retardant building products has a duty and a responsibility to have their products independently tested and accredited by third-party accreditation bodies, and to present the results to consumers, be they EN ISO 13501-1 STANDARDS FIRE BEHAVIOUR Class A1 – highest level non-burnable Class A2 – non-burnable materials Class B – inflammable materials Class C – normal flammable Class D – normal flammable Class E – normal flammable SMOKE DEVELOPMENT Class S1 – very limited smoke Class S2 – limited smoke Class S3 – no demands on smoke BURNING DROPLETS Class d0 – no droplets or particles Class d1 – limited burning droplets Class d2 – no demands on droplets Highest level for flame retardancy B – s1, d0 specifiers, contractors, or installers, clearly and unambiguously. Equally, specifiers and contractors have the responsibility to understand precisely what “flame retardant” means for the building products they are employing in any construction, large or small. www.itpltd.com Freefoam Building Products have got off to a good start in 2018 with the launch of two new product ranges: the Anthracite Grey Round Gutter System and the Acrylic interior panelling range. Colin St John, commercial director, explained: “New year is always a time for new opportunities. We’re delighted to launch these new products at the beginning of the year. It shows our commitment to creating new openings for our customers giving them the range to enter new markets and meet demand from both the housebuilder and the refurbishment sector.” Following the success of the PVC interior panelling products during 2017, Freefoam has now added a new range of Acrylic panels to augment the product offering. Designed to be easy to fit, the Acrylic panel range features a tongue and groove fitting system only available from Freefoam, and finished with attractive strong aluminium trims to give a robust and lasting installation. Panels are 1,000mm wide, 2,400mm long and 7mm thick to give coverage per panel of 2.40m². Featuring a translucent effect finish, Acrylic panels are available in a wide range of solid colours, from shades of aqua and red sparkle, to more contemporary mocha and brushed steel. Panels give any bathroom or kitchen a smart modern low maintenance look. The popularity of Ral 7016 Anthracite Grey for windows and doors is said to have been “phenomenal” over the last few years, featuring on many new housing developments around the county. Freefoam says it has consequentially seen sales of its deep rainwater range in Anthracite Grey increase over the last 18 months. The addition of a round gutter system is the next logical step to give Freefoam customers more choice and the flexibility to meet demand from housebuilders and specifiers. The Freefoam grey rainwater system is manufactured to Ral 7016, allowing customers to create a co-ordinated design with matching fascia, soffit and guttering, doors and windows. www.freefoam.com New year, new products EURO CLASS EN ISO 13501-1 UK BS 476 Parts 6 & 7 Class A1 NA Class A2 Class 0 Class B Class 0 Class C Class 1 Class D Class 1 Class E Class 2 Class F Class 3 Continued from page 46
