The Modern Alternative To Traditional Lead Flashing

The Lead Free Alternative - IKO Flash

Available from Greengates Builders Merchants Accrington, Lancashire IKO Flash the Lead free flashing.

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.

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 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
