Foam-Based Green Roof Systems

Innovative Green Roofing with Water Storage Mats of Polyurethane Foam

Green roof systems made of foam are particularly light in weight. That makes them ideal for intensive green roofing on flat or pitched roofs. They also provide for an easy, cost-effective installation on any roof. Lightweight green roof systems have an impressively long lifespan.

The polyurethane water storage mats have high water absorption capacity while diverting excess water. This keeps plants from becoming waterlogged. The ideal prerequisite for roof vegetation with turf, shrubbery or hedges as well as mosses, succulents, flowers or herbs.

The combined system of retention and drainage mats amounts to a thickness of just 70mm and is capable of water storage up to 42 l/m2. With a substrate layer, this can be increased up to 60 l/m2. For improved plant care and well-balanced environmental conditions. The integrated drainage layer safely protects the roof and increases the lifespan of the roof insulation.

Construction of an Intensive Roof Greening

With water storage mats of polyurethane

In the case of intensive roof greening, a water storage mat is laid on the roof membrane, which is then covered with a layer of substrate needed for vegetation. The water storage mat is equipped with the special foams HyPore Roof and TCL 40100, which store rain water to a certain extent, but also release excess water to prevent waterlogging of the plants. The foam HyPore Roof acts as a storage medium in the retention layer and TCL 40100 as a filter material in the drainage layer. The water storage mat has a total thickness of only 7 cm.

In application tests with external partners and test institutes, the company VIRIdiVITA has carried out precipitation simulations to evaluate the retention capacity and storage potential of the water storage mat.

The results speak for themselves:

  • Water retention capacity: 42 l/m2
  • Water discharge coefficient (C-value): 0.023
  • Precipitation retention: 97.7%

Advantages & Customer Benefits

Polyurethane foams offer numerous advantages over other materials, such as non-woven, mineral or stone wool, along the entire product life cycle - from manufacture to application and disposal. The HyPore Roof and TCL 40100 foams have been specially developed for the VIRIdiVITA premium roof water storage mats and offer the following properties.

Easy to Install

HyPore Roof and TCL 40100 are available already bonded as a combined retention and drainage mat with a material thickness of 70 mm. The mat can be cut to any desired size without special equipment, making installation extremely easy.

Lightweight

The water storage mat is particularly light, so that the mat in dry condition only weights 2.5 kg/m2 and in saturated condition 44.5 kg/m2. The substrate adds 92.5 kg/m2 and 110.5 kg/m2 respectively. This makes the lightweight roof greening system particularly suitable for flat and pitched roofs.

Lifespan

VIRIdiVITA premium roof water storage mats have a service life of about 30 years. 

Recyclable

It does not have to be disposed of as hazardous waste, as is the case with other materials, but can be recycled via the waste cycle management system.
