Extensive
A light rooftop garden, without worries
An extensive rooftop garden is what is commonly called “green roof”. It represents a system for green coverings with low width (16 cm), low weight (101 kg/m2 maximum) and little maintenance needed.
Since roof garden is a choice with technical functions, it should be evaluated according to its cost-benefit ratio; nevertheless, its aesthetic function is not neglected, it is pursued through careful selection of self-healing canopy vegetation, consisting mainly of a mixture of Sedum varieties and herbaceous perennials.

Simplicity and Resistance
Daku’s extensive gardens are ideal for rooftops with low accessibility, which need a simple system. It must be easy to maintain and capable of saving water. In these gardens, plants must me adaptable, resistant, able to regenerate and to reproduce themselves autonomously.
Daku’s extensive systems, thanks to the technology of their components, represent the ideal solution, combining efficiency and sustainability. Besides, they transform buildings into a part of the environment.

Rooftop Protection and Thermal Insulation
Rooftop gardens reduce the thermal dispersion during the winter, but most of all the coverings’ temperature during the summer. This allows to highly reduce energetic costs of buildings, both inside and outside. For these reasons, our extensive systems are ideal for buildings with rooftops difficult to access.
Besides, our green rooftops protect the hydraulic and insulation components of the covering. They also guarantee a longer operative life, keeping them functional e maintaining the rooftop’s economic and ecological value.

IRRIGA
DAKU IRRIGA ESTENSIVO permette il completo assorbimento dell’acqua fornita alle radici, limitando al minimo le perdite per evaporazione e drenaggio profondo, con l’effetto di abbassare anche del 75% i volumi d’acqua utilizzati per la sussistenza della vegetazione. Fornendo l’acqua dal basso, le piante traspirano ed aiutano ad abbassare le temperature superficiali e favoriscono la diminuzione del fenomeno delle “isole di calore” per periodi più prolungati rispetto alle alternative sul mercato.
