for the environment

Green roofs alleviate the air

pollution by photosynthesis and

the absorption and reduction of

air pollutants.

Just like all green spaces, large

extensive green roofs improve

the air quality in areas with high

building density and have a

positive effect on the “heat

island effect“.

Extensive green roof sites

compensate for the sealing of

natural areas caused by building

activities.

for people

It has been proved that the

esthetic aspect of the green

oases in the cities is good for

the human well-being and

improves the quality of life.

Green roof systems create

better working conditions since

they improve the indoor atmo-

sphere, particularly in summer.

Better working conditions

enhance the motivation to work.

A further benefit is the sound-

absorbing feature of the

vegetation cover.

In heavy rainfalls our system

retains large quantities of the

stormwater. Surplus water is

released to the gutters and

drains slowly and with a certain

delay. This substantially

reduces the strain on the

sewage system.

Optional:

The installation of an additional

special layer will protect the

interior rooms from electromag-

netic pollution.

benefits

Advantages and benefits of green roofs

and nature

The vegetation stock creates

new habitat for a variety of

micro-organisms and small

animals.

This way, our green roofs give

us back a piece of nature.

the roof construction

Our green roof protects the whole

roof construction from ultraviolet

rays.

The vegetation reduces the

differences between day and

night temperatures on the roof.

In summer and winter alike, it

protects the roof sealing from

peak temperatures. Furthermore,

the vegetative structure is a pro-

tective layer against dropping ice

fragments and hail.

All these effects lead to an

extended lifespan of the whole

roof construction, particularly the

sealing - up to 3 times as long as

the lifespan of a traditional roof.

When repairs or alterations on

the roof become necessary the

vegetation blankets are rolled up

and installed again when the job

is completed.

the building owner

costs

At first sight, the initial costs of a

green roof are greater than those

of a traditional roof. In the long

term it shows, however, that

green roofs are more cost

effective if following factors are

taken into consideration:

- extended lifespan of sealing

and roof construction

- less repairs to the roof

- reduced heating costs

- lower costs of airconditioning

(summer heat insulation)

- optional: lower costs of water

supply. The surplus water

which drains through the

filter fleeces of the green roof

system may be collected and

used for car wash, sanitary

facilities etc.

- better image due to the

application of environmentally

friendly technology.

- appreciation of value of the

building

installation

The installation is easy, quick,

and clean. Our system does not

require any soil. All materials are

just rolled out and laid on the

roof.

And the best of it: The roof is

instantly green!

load

Due to the low dead load of our

thin-layered vegetative structure,

only slight alterations to the roof

construction are required, if need

be.

security

The specific selection and com-

position of our systematic com-

ponents ensures safety against

wind uplift. Test certificates are

available.

Due to the pre-cultivation of our

vegetation blankets the vegeta-

tion stock offers immediate pro-

tection from erosion caused by

wind and rain.

Our components are hardly

inflammable and successfully

passed the relevant test.

maintenance

Our plants require extremely little

maintenance. A dose of fertilizer

once a year is sufficient.

There will be only little growth of

weeds, since most of them are

not able to survive in the very thin

substrate layer.

Due to the insignificant amount of

dead leaves special cleaning of

the gutters and drains is not

necessary.

vegetation

The plant selection is made

according to the regional climatic

conditions.
