The system using anti-root welding roofing roofing felt LEMBIT GREEN ROOF is a roof made in an inverted system of layers. Water in this system passes through all layers of the roof and is discharged to the outflow in the last layer, which is waterproofing. With the help of a system so developed and constructed, the roofs of all types of green are effectively and permanently covered with greenery.

• soothes the urban climate,
• reduces street noise,
• acts as an additional roof insulation,
• allows to recover biologically active surface lost for building,
• The use of vegetation on the roofs and facades of buildings is one of the element in architectural space shaping.

The system is based on FOUR basic layers:

• insulation layer - waterproof, resistant to root growth,
• drainage and filtration layer, which is designed to drain excess water, ventilate the roots and improve the insulation value of the roof structure,
• vegetation layer - it is a substrate which is made of a mixture of mineral rocks with appropriately selected granulation,
• plant layer.
