lpcb-isoqarPowerclad Keder Sheeting is reinforced sheeting incorporating keder roped hems, tailor-made to fit temporary roofing system scaffolds. It can be manufactured to fit most temporary roofing systems with varying designs.

Powerclad sheeting is manufactured using a full-width woven reinforcement fabric to provide a stronger sheeting product than those with welded seam joints.

It is available in a heavy duty Premium FR grade for exposed locations and long-term installations or a Standard grade for short-term projects. While the sheeting itself is waterproof, the limitations of the keder design do not necessarily provide a watertight system.

Both flame retardant and non-flame retardant grades are available. Flame retardant grades are LPCB approved to LPS 1215 and LPS 1207. All grades conform to BS 7955.

Industrial Textiles & Plastics Ltd is ISOQAR Quality Assured and certified to ISO 9001.

Installation

Powerclad Keder can be manufactured to fit most temporary roof systems. Since the designs vary, sheeting should be installed in accordance with the system manufacturer’s installation instructions.

Powerclad Keder is supplied rolled on a core for convenient installation. A scaffold tube can be passed through the core and the roll suspended off the floor to facilitate easy unwinding. The tension tube is passed through the leading edge sleeve and attached to the pulling rope which is passed over the roof. The keder hems are fed into the extrusion and the tension tube pulled carefully. Once the sheeting is hoisted into place, the tension tubes of the leading and trailing sleeves are secured according to the system manufacturer’s installation instructions.

Full installation instructions are included with every roll supplied.

Certification and Compliance

BS 7955:1999 This British Standard is for: Containment nets and sheets for construction works. Specification for performance and test methods. It specifies the minimum tensile strength of the scaffold sheeting, the eyelet strength and the ties.

Flame Retardancy

LPCB The Loss Prevention Certification Board (LPCB) has been working with industry and government for more than 100 years to set the standards needed to ensure that fire and security products and services perform effectively. LPCB has confirmed third-party approval for Powerclad FR products as they meet LPS 1207 and 1215 flame retardant standards.

LPS 1207 Loss Prevention Standard (LPS) 1207: Requirements for the LPCB approval for fire performance of temporary protective covering materials for use in the interior of buildings. This standard describes the fire test methods and performance requirements for ignitability, flammability, smoke emission, toxic gas emission and oxygen index. The performance requirements are intended to ensure that protective coverings for floors, walls, furnishings or other fixtures and fittings, in sheet or preformed form, used internally during construction or refurbishment of buildings do not significantly add to the fire risk. In case of printed sheeting, ink can effect the flame retardancy of the materials and separate flame retardant tests are required to obtain LPCB accreditation.

LPS 1215 Loss Prevention Standard (LPS) 1215: Requirements for the LPCB approval and listing for Fire Performance of Containment Nets and Sheet Materials for External Use on Construction Sites. This standard describes methods of tests and performance requirements with regard to flammability. The requirements set are those which should ensure that scaffold cladding materials such as sheeting and netting used externally during construction, refurbishment or demolition of buildings should not add to the fire risk. In case of printed sheeting and similar to LPS 1207, ink can effect the flame retardancy of the materials and separate flame retardant tests are required to obtain LPCB accreditation.
