IKOflash The Leed Free Alternative

IKO Flash the Lead free flashing now available from Greengates Builders Merchants Accrington, Lancashire

IKOflash is a lead free flashing which can be used in areas where traditional lead flashing would be used such as chimney and abutment flashings, around rooflights and pitched valley linings.

IKOflash is made from a modified polyethylene compound with an integral aluminium mesh reinforcement, enabling the product to be worked and formed in the same way as lead. The product is faced with a fine grey mineral.

Features and Benefits:

  • Can be worked and formed in the same way as lead
  • Available in 6m & 12m sizes
  • Significantly lighter than lead flashing making it easier to handle
  • Rapid installation
  • Cost effective, with no scrap or re-sale value
  • Non toxic material
  • IKOflash is ideal to use in areas where lead flashing would traditionally be used, e.g:
  • Stepping flashing
  • Abutment flashing
  • Chimney flashing
  • Pitched valley lining
  • Rooflights and solar panels
  • Dormers



IKOflash can be cut using a sharp knife and formed using the same methods as for traditional lead flashings.

If required, stainless steel nails can be used to fix IKOflash back to a structure. Standard fixing clips can be

used to secure IKOflash into a pointing gap, enabling the product to be secured firmly to allow dressing

down onto the roof covering. To provide additional restraint in areas of high exposure, IKOpro Stickall

elastomeric mastic should be applied in a continuous bead and pressed down to seal.

IKOpro Stickall can also be used to fill the pointing gap in brickwork and masonry, minimising any mortar

cracking or water penetration and ensuring a flexible, long-lasting joint.

All overlaps in IKOflash must be sealed with a continuous bead of IKOpro Stickall.
