ROOFTOP BIO-DIVERSITY
Sempergreen mature pre-cultivated sedum blankets and lightweight roofing systems. Broof(t1) fire rating, minimum 95% mature vegetation on installation day, and double the lifespan of underlying membranes.
Utilizing specialized mineral fiber retention boards, our lightweight systems can be installed on existing commercial roofs, timber canopies, and metal deck buildings without structural reinforcement.
Sempergreen engineered solutions accommodate flat 0° surfaces up to steep 45° pitches, employing shear-barrier grids and perimeter profiles to keep blankets anchored in heavy wind conditions.
Sedum blankets capture up to 90% of summer precipitation, discharging water gradually through natural transpiration. The blanket serves as a permanent physical buffer, protecting waterproofing membranes against hail, UV degradation, and thermal shock.
Sempergreen classic 4-layer engineering safeguards the structural membrane and promotes resilient plant growth.
Specialized puncture-resistant membrane shielding underlying waterproofing layers from root penetration and abrasion.
Dimpled retention panels holding essential moisture during dry spells while channeling surplus rainfall quickly to roof drains.
Lightweight, fire-resistant mineral growing medium providing nutrient-rich root support without excess deadweight.
Mature vegetation blanket featuring 6 to 8 sedum varieties acclimatized to northern winter cold down to -30 °C.
