KEY FACTORS

The following key factors have been assessed by the BBA when awarding HERTALAN® EPDM with certification:

Weathertightness — the systems and their joints, when completely sealed and consolidated, will resist the passage of moisture to the interior of the building (see section 6).
Properties in relation to fire — results of tests indicate that the systems will enable a roof to be unrestricted under the Building Regulations
(see section 7).
Resistance to wind uplift — when correctly specified, the systems will resist the effects of any wind suction likely to occur in practice (see section 8). Resistance to foot traffic — the systems will accept, without damage, the limited foot traffic and loads associated with installation and maintenance of the systems (see section 9).
Durability — under normal service conditions, the systems will provide a durable waterproof covering with a service life of at least 25 years
(see section 11).
