Introducing EverMat

The UK's hardest-wearing Sedum Matting system

  • 1

    Vegetation Layer

    We’ve finely tuned our plant selection to enable the best year-round performance. We only use long lived plants with the ability to self-propagate. Our plants are irrigated with mineral water from our own limestone aquifer, and are naturally fertilized with sea-weed extract, promoting healthy, long-lasting root system.

    Substrate (Growing Medium)

    Good substrate is of utmost importance to a thriving Green Roof. Blended locally and tested at Sheffield University to the German FLL Standard, our sedum grows in a porous, lightweight medium that retains oxygen, water and nutrients while providing stability for the plants’ roots.

    Drainage Layer

    The base layer is all about drainage. Water retention layers are not required. This is because Sedum is a member of the cactus family and so they store huge amounts of water. After it is installed you will never have to irrigate our Sedum blanket. 

Some of the benefits of our green roofs system

  • Noise Reduction

    A green roof system provides good sound insulation, keeps the living space quieter and creates more pleasant surroundings in urban areas. It contributes to noise reduction in large cities, near industrial areas and airports.

  • Rainwater Retention

    A major advantage of green roofs is the reduction of storm water run-off, which leads to a decrease of the burden on sewer systems by 70-95% in summer. Rainwater retention capability helps to limit flooding in urban areas. 1m2 of Core System with 95mm thickness absorbs 15 litres of rainwater.

  • Extended Roof Life

    Green roofs have been shown to triple the life expectancy of the roof. The underlying roof materials are protected from mechanical damage, ultraviolet radiation and extreme temperatures which results in reduced maintenance and renovation costs.

  • Cleaner Air

    The sedum plants on a green roof can capture airborne particles such as smog, heavy metals and volatile organic compounds from the atmosphere which has a positive effect on air quality and health of inhabitants. Researchers estimate that 1m2 of a green roof can help to absorb 0.2kg or airborne particles from the air every year.

  • Increases Biodiversity

    As urbanisation increases, ensuring biodiversity is one of the key requirements for local councils. Green Roofs can provide a habitat for various species and restore the ecological cycle disrupted by urban infrastructure. 

  • Co2 Reduction

    Green roofs help to reduce the amount of Co2 in the air, which is considered one of the most important causes of global warming. 1m2 of a green roof can absorb 5kg of Co2 yearly. As a perspective, 1m2 of green roof can absorb the same quantity of Co2 as a regular car would emit during a 80km drive.
