KNAUF Urbanscape Roof Garden System for pitched roofs 2045 to 50L

KNAUF Urbanscape Green Roof System for Steep Roofs 20–45°

System with 50 liters water storage capacity per m²

Covered roof gardens or steep roof surfaces offer many advantages for the public, private, economic, and social sectors.

The most critical component of a sloped green roof is the system that holds the vegetation layer and the Green Roll in place during the early stages of roof development.

Urbanscape Green Roof and Green Roof Covering Systems are an excellent and reliable solution for all roof pitches up to 45°.

Why should you choose the Urbanscape Green Roof System?

Complete solution The Urbanscape Green Roof System is delivered fully assembled, with easy-to-install layers directly to the customer.	Sustainable solution for our roofs The Urbanscape Green Roll growth mat is made from various pure, naturally occurring rock mixtures.
Fast and easy installation Typically, three persons can install up to 500 m² of Urbanscape Green Roof in one day.	Improved root growth Once installed, the roots quickly extend and reach the Urbanscape Green Roll with proper watering, gaining access to the stored water.
Low construction height We use the Urbanscape Green Roll growth mat, specifically designed to replace soil and further reduce the height of the green roof.	High water absorption and storage capacity The watering requirement is lower than with conventional roof substrates. The high water absorption provides an advantage for green roofs by reducing rainwater runoff.
Instant greening Using a SedumMix vegetation mat, the roof will look green in the shortest possible time.	Rainwater management Like in nature, water on extensive roofs undergoes natural biofiltration. This prevents pollutants and toxins from entering water bodies.
Lightweight green roofs On average, our Urbanscape Green Roll growth mat is 8 to 10 times lighter than conventional roof substrates.	Robust plants Sedum plants are good at storing water in their leaves and are suitable for changing weather conditions.

The "Urbanscape Detention Green Roof" system includes the following components:

• Urbanscape Green Roll D11, 3000x1000x40mm

Optional accessories only available as part of the roof covering package:

Inspection shaft
The Urbanscape inspection shaft is installed as part of the Urbanscape Green Roof System via the outlets on extensively vegetated roofs. It simplifies inspection and maintenance of drainage outlets. The shaft consists of a high-quality polypropylene base with a standing surface that distributes the weight, and a lockable cover with an integrated stainless steel filter grid to prevent overflow caused by accumulated material from the green roof and to protect against surface water from the vegetation layer. The custom-made inspection shaft also prevents contamination and overgrowth of the outlet by plants.

Edge profiles and corner profiles
The L-profiles are designed to separate vegetation and gravel on extensively vegetated roofs. They can also create boundary strips on a roof without a parapet wall. The triple-bent, L-shaped gravel strip made of perforated aluminum allows for permanent drainage. Each part is 2.5 m long and can be connected with an Urbanscape corner profile. As accessories, flexible Urbanscape corner profiles are available for easy on-site creation of interior or exterior corners.

Root protection foil
The Urbanscape root protection foil is made from black LD polyethylene regenerates. It is used to protect the waterproofing from damage caused by root growth.

Long-term fertilizer
A starter fertilizer is always recommended, as it makes plants more resistant and vigorous and accelerates root establishment. Typically, 30–40 g/m² should be applied. For maintenance, two fertilization applications of 30–40 g/m² each are recommended. We offer the long-term fertilizer in 1 kg, 5 kg, and 20 kg buckets.
