With the fire rating of waterproofing systems under increasing scrutiny since the Grenfell fire disaster, it is becoming increasingly important for specifiers and building owners to consider the fire classification of waterproofing systems.
The Mastic Asphalt Council (MAC) has recently tested its Recreation Duty (RD) Grade Mastic Asphalt system incorporating glass fibre tissue underlay to the European fire classification standard EN 13501-1. It successfully achieves a fire classification rating of Bfl-s1, confirming the product is flame-retardant with very limited smoke development.
MAC Director Malcolm Grinstead said: “At present it would seem few waterproofing systems have achieved the Bfl-s1 fire classification rating to the European Standard, and this confirms Mastic Asphalt is a great choice for specifiers who need to demonstrate excellent fire ratings for waterproofing products.”
Recreation Duty Mastic Asphalt is ideal for use on roofs, access walkways, balconies, terraces, podiums, plant rooms and stairways. It is UK manufactured, carbon neutral and recyclable.
For specifiers seeking an efficient, cost-effective and simple to install way to weatherproof the exposed parts of buildings, mastic asphalt is a proven, long-lasting surfacing material. Seamless, durable and with exceptional waterproofing characteristics, mastic asphalt can be installed with minimal disruption and downtime.
