Quality waterproofing build-up is the key

At the heart of the success of Index supplying and installing green roof system is its 30 years expertise in creating and manufacturing specific use bituminous waterproofing membranes and systems. Index operates in over 90 countries with plants in Italy and the US, and interests in Australia and Japan.

In the UK, Index Building Products Ltd., has been responsible for green roof systems ranging from the simplest over a theatre, to underground homes and a major visitor centre with 26 degree sloping roofs.

Whether the green roof solution is to satisfy environmental, water management, thermal or acoustic requirements or all of these Index provide a high level of technical support through its regional technical managers. A full design service is offered which includes specification, detail drawings and height and weight calculations. Once the project is under way they carry out site monitoring of the Index approved contractors work to ensure specification compliance before issuing anything up to 20 year insurance backed guarantees.

Standards

Index products have been independently tested by over 25 leading test institutions world wide including the BBA, ICITE and Factory Mutual. In addition the Defend Antiroots membrane not only conforms to European Standard EN 13948 but it has also passed the stringent FLL test. The installation of Index membranes and systems are only undertaken by an approved network of contractors to ensure that the quality ethos extends from manufacture through to specification and installation.

Systems

Index offer two main categories of green roof systems to suit different roof structures and landscape requirements.

Extensive: Light in weight with a shallow rootzone it is only capable of supporting hardy plants but requires little maintenance

Intensive: The only limitation to flowers, shrubs and trees planted in these roof gardens in the sky is the overall wet weight and live loadings that the building structure will bear for accessible recreation/leisure purposes. Index also offer Brown roof systems where natural seeding is promoted.

Index have published a detailed specification guide to Extensive green roofs and Intensive green roof gardens; they have been awarded CPD status by RIBA for their technical seminars and are a subscriber to the NBS Plus service which can provide instant access to standard specification clauses for Index membranes and systems.
