Introduction to Green Roofs
Green roofs, also known as vegetated roofs, eco-roofs, or garden roofs, are a key feature offered by Sika. These roofs involve a planted area on a flat or sloped roof, supporting a range of vegetation from low grasses and herbs to trees and shrubs, depending on the specific green roof type.
Benefits of Sika’s Green Roofs
Visual Appeal and Sustainability
Sika’s green roofs offer visual appeal, creating a park-like ambiance on rooftops. Moreover, these roofs can contribute to achieving sustainable building certification ratings.
Environmental Advantages
- Storm Water Management: Green roofs help slow down stormwater flow by retaining up to 75% of rainwater, thereby reducing pressure on stormwater and drainage infrastructure.
- Urban Heat Island Effect: They mitigate the urban heat island effect, contributing to a cooler environment.
- Air Quality Improvement: Increased green space on green roofs filters air, leading to improved air quality.
- Energy Efficiency: Green roofs reduce a building’s cooling energy consumption and costs, particularly during warmer months, due to the thermal mass effect.
- Waterproofing Protection: They extend the lifespan of waterproofing membranes by shielding them from UV rays and freeze-thaw cycles.
Financial and Property Benefits
Green roofs increase property value by providing a valuable building asset and offer financial savings through reduced energy consumption.
