advantages

With Sempergreen® vegetation blankets you immediately see an instant and mature green roof with little or no maintenance. A green roof with Sempergreen vegetation blankets has tremendous stormwater advantages with rain water retention of around 50-80% (depending on regional differences) and provides substantial energy saving. 

The advantages are:

- Instant green

- Visually attractive appearance

- Simple, quick and easy to apply

 - Minimum of 85% plant coverage upon installation

This is the highest in the industry, as most modular and bulk systems are installed with only 5-20% coverage and take 2-3 years to reach toe point our mats offer the moment you unroll them onto your roof.

- A lightweight solution (a green roof is possible starting from 4 lbs/square foot (100 kg/m²)

- most minimal  substrate layer comparing to extensive systems

- Rain water retention of around 50%

- Uniform drainage and purification of rainwater

- Resistant to all weather conditions where people can live as well

- Biodegradable

- Suitable for nearly all types of roofs and slopes

- Insulates in summer and winter

- Outdoor grown material is winter hard and can sustain abise of weather better than any bulk or modularly grown crop as this almost always takes place inside of sheltered greenhouses

- Sound damping

- less damage done by bird because of 85%+ vegetative coverage

- little or no maintenance system
