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.

IKOpro StickallIKOflash can be formed in the same way as traditional lead flashing. It can also be cut with either a sharp knife or lead snips and, if required, can be fixed back into the structure with stainless steel nails.

Where fitting IKOflash into a pointing gap, standard fixing clips can be used to hold the product firmly in place to allow for easier dressing down onto the roof covering. Where additional restraint is required in areas of high exposure, apply a continuous bead of IKOpro Stickall and press down to seal.

IKOpro Stickall can also be used to fill the pointing gap in brickwork or masonry. It will help to minimise any mortar cracking or water penetration issues, thus ensuring a flexible, long-lasting joint.

Seal overlap joints in IKOflash with a continuous bead of IKOpro Stickall.
