Transforming walls into living
masterpieces

You can get a budget quote by sending us a detailed drawing with dimensions and drawings that show the location of the wall and accessibility of the wall from the ground. It costs Sempergreen a lot of time to do a
detailed quote and without having visited the site, understanding access restrictions, time of year installation, etc. therefore, we can only give you an approximate cost price per square feet. This budget quote should typically be within $5-15 per sqft from the quoted installed price. The bigger the green wall, the smaller the discrepancy will be. Once a project becomes real, the installation company can inspect the site and look at detailed drawings; which will allow Sempergreen to produce a more precise, installed green wall quote.

A SemperGreenwall can be installed on any surface, provided that, the surface meets anchoring requirements and is able to hold the weight of the wall which is approximately 9-10lbs/sqft or 45kg/m2. In order to anchor the wall, the vertical omega profiles, on which the Flexipanels hang, needs to be able to be secured to the wall with a screw or bolt every 2-3 vertical feet. Therefore, the wall needs to be able to anchor these fasteners and hold the weight of the system that is transferred to the screws or bolts.

The PCS is a smart system that evaluates all inputs into a green wall system and irrigates accordingly; adjusting for daily weather changes and seasonal differences in plant needs. This system protects a SemperGreenwall investment by constantly measuring all of the environmental conditions that the green wall is exposed to and
monitors the moisture conditions in the root zone. Due to this constant evaluation of the conditions, the PCS eliminates the reason most green walls fail, human error (turning off the water (de-hydration), poor winterizing schedules (winter plant loss), and stuck or broken valves that dehydrate portions of the wall). In the event that
any of these or other events occur, the PCS will send a report via phone or email. This allows the issue to be fixed before any harm is done do the plants. This report gives the responsible person a sufficient time to correct the issue or put measures in place to avoid harm to the plants. The PCS also keeps a record of all issues that occur, and this report can be accessed at any time in order to assess where an issue may have occurred in the event of unforeseen damage to the plants.

Sempergreen prefers that you set the parameters of the
design. You can emphasize if you like seasonality (changing
with the seasons like a real garden), level of blooming color
(lots or little flowering), modesty (lots of green vegetation
with little flowers), or perhaps a design with different
shapes or a logo. Once you set out the parameters, we
would like to fill in the details. We will suggest to you a
series of plants that we know perform well in the green
wall and that will work well with your design criteria, but
ultimately you as the designer have the final word. If you
choose plant species that we are not familiar working with,
it may void the warranty on these plants, so it is highly
advisable to follow our guidance with plant choices. For
outdoor walls we highly recommend using a substantial
portion of evergreens or semi-evergreens in order to have
the green wall look presentable in winter as well.

An Interior SemperGreenwall requires a light source from above that falls onto the top of the plant leaf. This light source should provide 800-1200 LUX, or 75-110 Foot candles across the complete green wall.

No, Sempergreen monitors all of the green walls they install in order to ensure that they are maintained properly
and up to the Sempergreen standards. Depending on the location, Sempergreen may maintain it themselves or
outsource the maintenance to an approved third party. In some markets, we work with the local companies that
will perform some of the visits, but Sempergreen will still supervise each project and will monitor all of the walls
remotely. Our reputation is at stake and we take this very seriously.

Sempergreen or its licensed installers will visit the green wall 7-9 times per year. Twice a year the SemperGreenwall will be pruned; in the spring, we apply a hard pruning that keeps the plants orderly and in
the fall we will do a light pruning. Fall pruning is done lightly because the plant uses winter foliage to protect itself from the harsh weather and often energy is stored in the above ground stems and leaves that is available to the plant during times of stress (winter). The other 5-7 visits are check-ups and cleanup visits where we will manicure the green wall, double check equipment functioning, inspect the system for leaks or any other issues, and evaluate plant health and potential insect problems that may need to be addressed. Once more, happy plants mean less disease and less insect problems, and Sempergreen Flexipanels are the only green wall components that allow for plants to grow just like if they were in the garden.
