There are many roof garden options available to todays designers and specifiers. The two main green-roof technologies are known as the Intensive Roof Garden or the Extensive Roof Garden.
Extensive
The Extensive system is a hardy mat of sedum vegetation that requires little maintenance. Our fully trained green-roof installation engineers are able to build and install systems of any size in a cost and time efficient manner.
Intensive
The Intensive system is simply a garden on the roof. Whether it is landscaping, lawn, trees, shrubs or ponds; Intensive green roofs need the same care and maintenance of any ground level garden. BBS Green-Roofing’s horticultural expertise is essential in the construction and maintenance of such a system, and of course, essential in the combination of the two systems.
Green Roofs can be sown, planted or installed fully grown:
Fully Grown Sedum Mat - NutriMat
A fully cultivated sedum mat that is cut into manageable turf like tiles with 3 layers as one.
Build in Situ
Installed layer by layer with sedum sprouts scattered evenly and softly pressed. This is the most economical way to plant a green roof. The sedum will be fully mature in 18 months and flowers will begin to appear after one growing season.
<60º Pitch Roof:
We can also install onto pitched roofs up to 60º using sedum honeycombs. These have been cultivated for a minimum of 18 months to FLL standard and are then fixed and laid, much like the Fully Grown Sedum Mat.
Brown Roofs and Biodiverse Roofs:
Multilayered low cost alternatives, generally cleaned soils from site and either allowed to self populate or sown in situ with wildflowers, herbs and grasses.
Pregrown WildMat:
Alternative to a sedum roof. Pregrown wildflowers and grasses for instant impact.
One Layer Fully Grown Leightweight System
This technology was developed over 25 years ago from millions of metres of green roofs across Europe and those early roofs are still as beautiful today as the day they were installed. This ultra efficient, 3 layer-in-one tile is lightweight, easy to install and in our opinion is a superior system and what's more is the most cost efficient.
The mats are made from recycled, open-pore, CFC-free PUR soft foam; incorporating clay minerals and plant nourishing elements as long-term fertiliser.
When installed in situ the mats give the fastest vegetation establishment in comparative tests.
The Established NutriMat system has a water storage capacity of up to 25 litres and a total saturated weight of 56 kilos per square metre.
