The system is suitable for use on:

Concrete
Asphalt
Plywood
Reinforced Bituminous membranes
Insulation

Previously coated surfaces
Small areas of metal incidental to the roof e.g. pipe upstands
Small areas of plastic-coated metal incidental to the roof

Durability

30 Years 

Under normal service conditions, the system will have a life in excess of 30 years, provided it is designed, installed and maintained in accordance with this Certificate and the Certificate holder’s instructions.

When fully protected, under normal service conditions, the system will have a life at least equivalent to the roof in which it is incorporated, provided it is designed, installed and maintained in accordance with this Certificate and the Certificate holder’s instructions.

In situations where maintenance or repair of any of the components in the roof structure are necessary (eg protection layer or insulation), the durability of the system may be In these circumstances, the Certificate holder must be consulted, but such advice is outside the scope of this Certificate.

An estimation cannot be given for the life of green roof specifications owing to the nature of use; however, under normal circumstances, it will be significantly greater than for exposed waterproof coverings.

Installation Requirements

Practicability of installation was assessed by the BBA on the basis of Certificate holder’s information. To achieve the performance described in this Certificate, the system must only be installed by contractors who have been trained and approved by the Certificate holder.

Fire Safety

When tested to CEN/TS 1187 : 2012, Test 4 and classified to BS EN 13501-5 : 2016, the construction given in Table 1 of the BBA Certificate achieved BROOF(t4) for slopes below 10°.
