MEGASPAN

Megaspan is an insulated roof panel that provides a simple, cost effective solution to most integrated ceiling needs. A Megaspan panel is comprised of a metal roof sheet, bonded to a core of 16kg/m3 Sagex FR Expanded Polystyrene, finished with a chromadek steel laminate or alternative finishes e.g. fibre cement, ABS or PVC.

QUALITY MANAGEMENT SYSTEM
ISO 9001:2000 in progress.
FEATURES & BENEFITS
  • Megaspan has been tested for wind, hail & snow loadings.
  • All in one package - roof / insulation / ceiling
  • Reduced installation time
  • Fire risk greatly reduced as EPS is encapsulated between 2 fire resistant laminates
  • Properties of EPS used in Megaspan
    • EPS is resistant to aging, mildew, bacteria & rot
    • EPS is physiologically and chemically harmless
ACOUSTIC PERFORMANCE
Not suitable in acoustical applications but can reduce rain & hail noise. Isover offers a range of alternative acoustical insulation products if required.
DURABILITY
THERMAL PROPERTIES
Refer to physical properties table.
  • Odourless, inert and fully compatible with all standard building materials & components
  • Will not promote corrosion of steel, copper or aluminium
  • Will not sustain vermin
  • Will not breed or promote fungi, mould or bacteria
  • Rot proof
APPLICATION
Megaspan is suitable for all building applications where its thermal and sound dampening properties can be of benefit. Megaspan is especially suited to certain farming applications, such as insulation of poultry batteries and piggeries. Megaspan also has a variety of commercial and industrial uses eg: medical and educational institutions. In addition, Megaspan is widely used in domestic housing, and can also be used in vertical cladding.

Megaspan is self supporting up to 3.7 m x 50 mm thick for chromadek ceiling & 3.6 m span for fibre cement ceilings, reducing or even eliminating structural support. Megaspan integrates the roof, ceiling and insulation - increasing the interior volume of structures, and is quickly and simply erected.

TOOLS NEEDED FOR INSTALLATION
Conventional roofing / ceiling contractors tools.
INSTALLATION INSTRUCTIONS
  1. Megaspan panels should be laid on top of the purlins (timber or steel) and fixed through the flute into the purlin below. Fixing can be effected by either self drilling and tapping screws (Topspeed) or hook bolts with sealing washers.
  2. Side-lap joints should be sealed at the overlapping flute and stitched with pop rivets at 900 mm centres.
  3. The end-lap joint to occur on top of a purlin and sealed with two rows of good quality polyurethane sealant or preformed adhesive strip sealer.
  4. Panels must be supported at the ridge by either purlins or a ridge beam and weatherproofed by means of a standard ridge cap.
  5. At the eaves the panels should be secured by fixing into a timber wall-plate, which should be fixed in accordance with current building regulations.
HANDLING & STORAGE
Megaspan should always be protected from the elements and carried individually on edge. As per all items in storage, the same fire safety regulations should always be considered. All health & safety regulations should be adhered to and complied with.
