Altolead Plus Flashing

Alto Lead Plus is a high performance flashing, very similar in appearance to actual lead.

Alto Lead Plus offers a low cost alternative to traditional lead and is suitable
for both flat and pitched roof applications. Its smooth finish has a three layer construction, consisting of a modified plastic with a backing of polyisobutylene, and an expanded Aluminium mesh integrated in between.

The unique Aluminium core construction ensures that Alto Lead Plus is extremely strong and flexible, allowing it to be shaped again and again without leaving visible fracture marks. The polyisobutylene adhesive backing creates a permanent bond to all sound building materials and waterproof joints are achieved without the need for adding tape or sealant.

Alto Lead Plus requires no primer, unless the surface to which it is to be applied is unstable. In this instance a bituminous primer must be used. Due to its lightweight construction, Alto Lead Plus can be cut and shaped with a knife or scissors. Consequently installation is rapid, thanks to its ease of cutting and simple to remove, silicone film release backing paper.

Alto Lead Plus has a life expectancy in excess of 20 years.

Whilst Alto Lead Plus has many similar properties of traditional lead, it has no re-sale or scrap value , deterring potential theft and vandalism

Alto Lead Plus can be installed and worked in any direction using a mallet, roller or by hand and can be cut using scissors or a knife.
The silicone release film should be left in place until the final shape and position is determined, before being fixed.

The surface to which Alto Lead Plus is to be applied should be clean and dry to achieve a permanent adhesion. If the building material surface is unstable then a bituminous primer must also be used.

Alto Lead Plus should be dressed into the brickwork and sealed. Where top edges are exposed, you will need to use a sealant* to prevent ingress of rainwater behind the flashing. Alternatively, a cover flashing turned into the joints of the brickwork can be used.

All jointing detail should have a minimum overlap of 100mm and a roller should be used to apply maximum pressure.
