XERO FLOR SUPER LIGHT

The lightest system solution. Used on lightweight roofs whose load-bearing capacity is low, approx. 30-40 kg/m2.

The vegetation layer is a storage geotextile with the weight of 1000 g/m2. The system provides minimum living conditions for plants. Several layers of geotextile can be used to increase the water buffer and ensure better conditions for sedum growth.

The use of drainage with filter geotextile depends on the roof inclination angle. The final arrangement of layers depends on the design assumptions and technical conditions.

Xero Flor Superlight

XERO FLOR LIGHT

Used both on flat and pitched roofs up to 45o. The advantages of the system are lower costs of transport, unloading and installation of wool compared to the substrate.

The vegetation layer in the form of hygroscopic rock wool with a water storage capacity of 18 l/m2. One or two layers can be used. It is suitable for stacking and creating living conditions for plants with a developed root system.

The use of drainage with filter geotextile depends on the roof inclination angle. The final arrangement of layers depends on the design assumptions and technical conditions.

Xero Flor Light

XERO FLOR HYBRID

Used on flat roofs and roofs with a slight slope.

The vegetation layer in the form of hygroscopic rock wool and mineral substrate. The combination of two types of substrate provides the most favorable conditions for plant development.

The use of drainage with filter geotextile depends on the roof inclination angle. The final arrangement of layers depends on the design assumptions and technical conditions.

Xero Flor Hybryda

XERO FLOR SUBSTRATE

Used on flat roofs with a solid structure. The heaviest solution available.

The vegetation layer in the form of a mineral substrate with a negligible share of the organic part. The use of drainage with filter geotextile depends on the roof inclination angle. The final arrangement of layers depends on the design assumptions and technical conditions.
