What are the benefits of living walls?
There are so many benefits that can be felt with living walls. The following are just a few examples: Living walls conserve energy by insulating the building envelope, reducing the need for heating in the winter and cooling in the summer. They create biodiversity conservation opportunities, and absorb and filter storm water, which reduces local water body pollution and helps prevent the overwhelming of municipal storm water infrastructure. Living walls also filter air particulates, improving air quality and help to reduce the urban heat island effect (UHI). With our interior kits the plants clean the air in your office or home and also add humidity to the air when you have your central heating on in the winter.
What is the weight of Living Wall panel?
Unplanted panels weigh approximately 2kg each. Our newest living wall panel 100cm x 100cm with 30, 36 or 64 pockets gives plenty of planting space for an increased variety of plants - either native or exotic. Fully saturated and planted weight can be as much as 76k per square mete so a sturdy frame or concrete wall is best.
Panel sizes available (width x height)
- 100cm x 100cm, 30/36/64 pockets
- 100cm x 50cm, 15/18/32 pockets

|What is the weight of a Living Wall
Our unplanted panels weigh approximately 2kg each. Our newest living wall panel - 100cm x 100cm gives plenty of planting space for an increased variety of plants - either native or exotic. Fully saturated and planted weight can be as much as 45kg - 76kg per sqm, so a sturdy frame or concrete wall is best.
|How do the plants stay in the
Each panel has pockets which keep the soil
and plants in. The roots of the plants also spread
throughout the panel securing the plants in place.
|Do I need to plant every pocket
in the panels?
The plants you choose will influence this decision.
You can choose plants that spread or are larger
when they fill in and plant every few cells, or
more compact plants that suggest planting every
pocket. It is up to you what look you are trying to
|How do the panels attach to a wall?
Direct wall installations are very simple. We suggest
first covering the wall with a waterproofing material. Either mount them directly on the wall with the supplied screws and plugs or on sturdy framing.
|What plants do people plant in them?
Plant choice varies greatly depending on budget,
taste and aspect. With the generous planting depth there is a great variety of plants to choose
from - both for internal or exterior walls. Our
full design consultation service is available.
|Can I grow vegetables in my
Living wall panels can take many varieties of salad crops and vegetables. Strawberries do very well as do herbs.
|How are the walls watered?
The panels are designed to allow water flow from
pocket to pocket within each panel and then from panel
to panel in a complete wall. For direct mount wall
installations we suggest installing a drip irrigation
line between every row of panels depending on the
micro climate of the installation.
|How much water do the walls need?
The amount of water required is plant and climate
dependant but an average would be approximately 8 liters
per panel per watering. We always say - keep an eye on your plants,
they will look sad if they need water.
|What are the maintenance requirements?
The living wall panels requires very little maintenance. With carefully
selected plants and proper irrigation they take
care of themselves. The only thing that may need
to be done is the odd trimming of dead leaves, fertilizing or adding plants as necessary if replacements
are needed. It is very similar to house or garden
plants in that way.
|What happens to my living wall in the winter?
For outdoor applications only this depends on your
geographical location, climate and the plants selected.
Some sedum species are evergreen and will turn a
shade of maroon in the winter but will then return
to their green color as soon as spring appears.
Some grasses will go dormant and look brown all
winter but then will regenerate from the centre
of the plant, turning green again in the spring.
In some of the warmer climates the plants survive
all year round. Of course in some of our extreme
cold climates the plants will recess into the cells
of the panels to come back out again in the spring
just as perennials do in the garden. To avoid this
you can also plant all season evergreen plants in
our panels if you use extensions. For indoor use
they are just beautiful all year round.
|Can I install living walls on my own?
Yes! The living wall panels are for individual use as well as
|Why are our living walls considered sustainable?
Each living wall panel has 30, 36 or 64 individual
pockets which help regulate the water flow so plants retain
water for a long enough time without getting 'soggy
feet' and then the water filters down through to
the bottom of the panel to the only exit route for
any excess water.
|If I am doing a direct wall installation
what do I need to have prepared?
You will need to waterproof the area that will house
the living wall panels and irrigation controllers.
You will also need a water source and electrical
outlet brought to the wall and a drain detail at
the bottom of the wall.
|What size irrigation line do we use for
direct wall installations?
We run 4mm to 12mm line horizontally across the panels. We would recommend installing
lines every 1 row. These lines are generally fed
by a water supply line.
|What kind of light do I need for my living
It is best to locate your wall where it will receive
some natural light. Otherwise you can augment with
artificial if necessary. The most important thing
is to specify plants that will survive where you
are planting them. There are some species that survive
very well for instance in low light. Others require
more light. Talk to the plant experts or refer to
the suggestions on our website.
What are the benefits of green roofs?
There are so many benefits that can be felt with
green roofs. The following are just a few examples:
Green roofs conserve energy by insulating the building
envelope, reducing the need for heating in the winter
and cooling in the summer. They also extend a roof's
life by protecting the membrane and create biodiversity
conservation opportunities. They absorb and filter
storm water which reduces local water body pollution
and helps prevent the overload of municipal storm
water infrastructure. Green roofs also filter air
particulates, improving air quality and help to
reduce the urban heat island effect (UHI).
|What is the weight of a Green
Extensive systems range from 50kg saturated
per square metre depending on your climate and depth
of the panels ordered. The soil depth is specified
in accordance with the plants used and the microclimate
of the project. The intensive roofs generally start
at 150k and higher depending on the plants used.
|What plants do you use?
Our extensive pre-grown system uses a
variety of sedum species specially chosen to thrive
in your climate. Sedum are chosen for their drought
tolerance and hardiness and the species used vary
depending on the hardiness zone and the type of
project. With our planted in place and intensive
systems there are many plant choices. We like to
use Native plants & sedum whenever possible
and we also use a variety of perennials, shrubs
and grasses. There are many types of plants that
can be grown on the all in one system. The factors
that will affect your choices are your climate zone,
irrigation supply, budget, exposure, and load bearing
capacity. Our talented designers can help you choose
the plants that are right for you.
|What are the maintenance requirements of
the 3 types of Green Roofs?
Pre-grown extensive roofs require very little maintenance
as the plants are fully mature and hardy upon delivery.
Generally 4 maintenance visits are required per
year. The planted in place extensive roofs require
more maintenance for the first 2 years during the
plant establishment period and then become low maintenance
like the pre-grown in the following years. The intensive
roofs require the most maintenance. Maintenance
visits are dependant upon design. Although most
sedum and other properly selected perennials can
survive an extended period without irrigation, it
is advisable to install a simple auto control drip
line irrigation system with every green roof. The
water wicking capabilities of our system spreads
the water out over the roof in a very efficient
manner. making irrigation times very minimal. The
irrigation system provides moisture as required
during periods of drought. With the changes in our
climate there are extended drought periods in most
areas and plants all require water to survive. Irrigation
is included in the Vertical Plantscape quotations.
|What is the cost of an green roof?
Per square meter costs can vary greatly depending on the type of green roof, installation costs, location of site, whether the roof
has a balustrade and access.
|How far in advance should I order my green
Please contact us to check stock levels in your area of our pre-grown
extensive panels. The planted in place system has
a fairly quick turn around time and is installed
by using plant plugs which we grow at well experienced
grower nurseries. After discussing the details of
your installation with one of our project managers,
we can outline the time lines
needed for your green roof installation.
|Is my roof more likely to leak with a green
roof on it?
This is one of the most misunderstood issues surrounding
green roofing. A green roof must be installed over
a roof that has a waterproofing membrane that is
in excellent condition. Green roofs are not meant
to fix a leaky roof. In effect your green roof actually
lives about an inch above the roof allowing water
to drain off normally. With a high quality waterproof
membrane your roof is extremely well protected against
leaks and it has been shown that adding a green
roof can actually more than double the life of your
membrane or more. This is possible because the roof
is protected from damaging UV rays as well as the
constant heating and cooling cycles which cause
expansion and contraction leading to cracks in your
membrane over time. Not to mention the cushioning
that a green roof provides against hail and falling
debris that could otherwise damage your waterproofing.
|What is the maximum slope that you can install
a green roof on?
We recommend using Pre-grown roof panels
on slopes up to 25%. The pre-grown panels have plants
that are already rooted into the hemp bio-blanket
which holds the growth medium in place as well as
the plants. We would use our living wall panels
for roofs over 25% slope right up to vertical applications.
Now there is no slope that cannot be greened.
|What happens to my green roof in the winter?
This depends on your location and the plants selected.
The majority of sedum are evergreen and will turn
a shade of maroon in the winter but will then return
to their green colour as soon as spring appears.
Some grasses will go dormant and look brown all
winter but then will regenerate from the centre
of the plant, turning green again after the first
few warm spring rains. Other perennials will do
just as they do in your garden.
|How is a green roof affected by wind uplift?
Each project is unique presenting different wind
uplift problems in different locations. After a
wind analysis of the building is done to see high
wind uplift areas, a fastening plan can be designed.
This may be as simple as additional ballast in the
form of river rock or paving stones around the perimeter
or could even involve point loading deeper depths
of substrate over beams or columns. All of these
solutions can be custom designed to create a beautiful
planted berm or paver edge detail that will both
resist wind uplift as well as contribute to the
overall aesthetics on the roof. For sloped and flat
roofs without parapets there are a variety of mechanical
fasteners that can be implemented around the perimeter
that provide a nice clean edge but also securely
fasten the green roof to the structure, all without
impeding drainage off the edge.
|Can I install a green roof on my own?
We have recently developed a Do It Yourself Green
Roof system with either pre-grown or plant-in-place
panels. We will be offering this to customers in
the form of a custom green roof kit. You will need
to supply us with the dimensions of your roof and
we will provide you with all the different components
you need to make it green.
|Can I grow trees and bushes and roses and
vegetables in my green roof?
If your roof can support the added weight of the
soil and plants when fully saturated and fully grown,
then yes. More times than anything the load limit
of a structure is what determines what plants can
be grown on the roof. If the building is a new construction
then these larger loads can be designed into the
structure from the beginning allowing for more planting
|How long does it take to install my green
Most residential projects can be installed within a few days. Most commercial installations can take up to one week or longer due to generally larger roof sizes. The installation process with the all-in-one roof system available from Vertical Plantscapes makes for one of the quickest installations available. Installation time will depend on size and detail of project.
