Flashing (Non Lead)

Alumasc Roofing Systems

ProFlash can be used in areas where traditional lead flashing would be used such as chimney and abutment flashings, around rooflights and pitched valley linings. ProFlash can also be used to form a damp proof course and cavity trays in masonry walls. ProFlash 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 black mineral.

Application

  • ProFlash can be cut using a sharp heavy duty knife or metal cutters and formed using the same methods as for traditional lead flashings.
  • If required, stainless steel nails can be used to fix ProFlash back to a structure.
  • Standard fixing clips can be used to secure ProFlash 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, bituminous mastic should be applied in a continuous bead and pressed down to seal.
  • Bituminous mastic 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 ProFlash must be sealed with a continuous bead of bituminous mastic.
  • Lead free is the modern day alternative to older lead product and can can be utilised in the same areas where traditional lead flashing would have been used such as chimney and abutment flashings, around rooflights and various lining areas.
  • Lead free flashing 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 and provided a clean, tidy finish to these areas.
