    PROTAN EXTENSIVE GREEN ROOF SYSTEM ON STEEL SUBSTRATE

    Extensive green roofs are characterised by the roof being covered with a thin layer of soil or growing medium mats, typically planted with succulent and moss species.

    Extensive green roofs generally require little maintenance and offer great potential in terms of applications. They are light weight and do not require a heavy-duty load-bearing structure which is required by intensive green roofs

    The wind forces on the roof have to be taken into account on all roof structures. The sedum mats can only be laid in the warm season. Due to the low weight of the green roof layers, the membrane has to be calculated to withstand wind loads and may have to be fastened mechanically.

    The membrane has to satisfy fire safety requirements without cover until the sedum mats are installed or in the event that the sedum mats are not fire rated. Our membrane is self-extinguishing and is classified according to EN 13501-5. Larger roofs require fire barriers. At upstands and penetrations the growing medium has to be separated by barriers in the form of concrete blocks, pebbles, etc., to prevent fire from spreading.

    Protan SE Titanium + membrane has been certified root resistant in accordance with the FLL test (Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau) and does not require extra protection such as root barriers.

    CONSTRUCTION STRUCTURE:

    • EXTENSIVE GREEN ROOF LAYERS - SEDUM / DRAINAGE & RESERVOIR LAYER
    • PROTAN SE TITANIUM + MEMBRANE
    • PROTAN APPROVED FASTENERS
    • INSULATION
    • VAPOUR CONTROL LAYER
    • STEEL SUBSTRATE

    PROTAN SE TITANIUM+ MEMBRANE

    • Protan SE Titanium + membrane is a root-resistant PVC membrane with a polyester reinforcement that is designed for extensive sedum roofs. The polyester reinforcement makes it optimal for mechanical fastening when necessary. The product is well suited with regards to protection against UV rays, variations in temperature and micro-organisms.
    • Because the sedum plants can only be installed during the summer, it is important to use a membrane that can be both mechanically fastened and fire classified. Protan SE Titanium+ membrane is Broof (t1) and Broof (t2) fire classified.

     SYSTEM INSTALLATION METHOD:

    • Protan Standard Overlap System - The membrane is fastened to the substrate along the longitudinal sheet edges and overlapped by the adjoining roll. The two rolls are welded together using hot air.
    • Protan Prefabricated Sheets system is the best and fastest solution in wind-exposed areas, so it is ideal when the roof has to be covered quickly. The membrane is provided in 2 or 4 metre widths with high strength strips welded longitudinally on the underside for mechanical fastening.
    • The Protan Secret Fix System uses a membrane in 2-metre widths with extra strong strips welded transversely to the underside for mechanical fastening.

    Please contact Protan for further advice.

    FASTENERS:

    • Protan approved - must be calculated according to EN 1991-1-4 alongside national annexes and local regulations.

    INSULATION:

    Various types of insulation can be used in combination with Protan membranes and can be flat insulation or sloped insulation. The material type and design will depend on the building design, fire classification and local regulation requirements.

    • Mineral wool (MW) – can be glass or stone type
    • Polyisocyanurate (PIR) - foil faced
    • Combination EPS-MW

    VAPOUR CONTROL LAYER:

    • Polyethylene
    • Bitumen

    STEEL SUBSTRATE:

    • Profiled metal decking consists of galvanised steel. Minimum recommended thickness 0.7mm to EN 10346 Fe E280G Z275 or local regulations.
