Monarflex Kederflex Temporary Roof Covering

Monarflex Kederflex Clear - High performance temporary roof covering

Monarflex® Kederflex is a temporary covering system for roofs and facades that serves as a climate shield and work site containment to keep the weather elements out of the work site and at the same time contains any objects or debris from escaping the work area to harm for the surroundings at street level.

The special Kederflex material is not just a containment sheeting it´s also simple to install due to its low friction keder bands and unique Monarflex eyelets that allows proper and secure fixing. Once installed the Kederflex offers the perfect work climate with plenty of natural light despite being white tinted due to its flame retardant additives. At end of life cycle it can be reused thanks to its environmentally friendly halogen free composition. All this makes it the ultimate covering material available.

  • Product Range

    The Monarflex Kederflex Clear is made from a three ply composition with the two outer layers being made from a special highly weather resistant copolymer halogen free flame retardant LDPE mix that encapsulates an extremely strong polyester (PET) high tenacity grid which forms the weather protection layer. On top of the sheet there are rubber fixing eyelets that, if needed, help secure the Kederflex in high winds. The eyelets, which are a patented solution, are welded onto the sheet to provide the strongest and most durable eyelet fixing on the market.

  • Application & Fixing Details

    Monarflex Kederflex sheeting is available in widths which form a system that suits most standard scaffold Keder systems. The Kederflex sheeting is applied by “threading” the Kederflex bead into the rail track scaffold Keder frame and simply pull it from one side to the other of the roof using a rope fixed to a rod which is placed in the pre-formed back fold pockets on the Kederflex sheeting. In case of high snow loads these should be removed from the surface to reduce weight strain on the scaffold structure and Kederflex sheeting.

    Fixing Details

    Kederflex-Fixing-Details1. Steel eyelet.

    2. Monarflex Eyelets - secure noise reduction and safe passage for the water.

    3. Half ring cutouts – for safe and easy installation, fasten the installation rod with pulling wires. 

    4. Steel eyelet couple – to pull the sheet down to decking level. May also be used to fasten the sheets.

    5. Keder cord – in low friction band for ease of installation with a standard 12 mm bead

    6. Backfolding, B – to pull out the sheet on the scaffold structure during installation.

  • Accessories

    The well known special designed Monarflex Accessories are also available for the Kederflex to ensure a proper and correct installation. The unique Monarflex eyelets in the centre of the Kederflex sheeting can be used for securing flapping movement by the use of the Monarflex Polytoggle that’s a watertight accessory that clicks into the Monarflex eyelet. It ensures an easy way of tying the sheeting down with rope or similar. 

    Repair Kit
