By Sika’s green roofs, also known as vegetated roofs, eco-roofs, or garden roofs, feature planted areas on flat or sloped roofs. These roofs can host a variety of vegetation, from low grasses and herbs to trees and shrubs, depending on the specific type of green roof.
Benefits of Sika’s Green Roofs
Aesthetic and Environmental Advantages
Sika’s green roofs provide a visually appealing, park-like ambiance on rooftops. They contribute significantly to sustainable building certifications and offer numerous environmental benefits.
Storm Water Management
These roofs can retain up to 75% of rainwater, which helps slow down storm water flow and alleviates the pressure on drainage infrastructure.
Urban Heat Reduction
Green roofs reduce the urban heat island effect, helping to moderate temperatures in urban areas.
Air Quality Improvement
Increased green space on roofs improves air quality by filtering pollutants.
Energy Efficiency
The thermal mass effect of green roofs reduces a building’s cooling energy consumption and costs, especially during warmer months.
Longevity and Value
Green roofs extend the lifespan of the waterproofing membrane by protecting it from UV rays and freeze-thaw cycles. Additionally, they increase property value by adding a valuable asset to the building.
