  • Description & Key Features

    Product Description

    Our Performance Range of brickwork abutment cavity trays come complete with an integral lead free flashing comprising of a stretchable aluminium grid embedded in an environmentally friendly polymer rubber. Working with this material is comparable to working with lead only it is even easier to use and shape because of the good stretching properties and low weight. The lead free flashing material maintains the high levels of malleability and weathertightness that traditional lead provides yet has the benefits of being lighter, non-toxic and significantly reduces the likeliness of theft owing to it having no resale value.

    The Performance Range is available on short lead applications for use with lead soakers and secret gutted upstands at the abutment, providing a vertical drop of 75mm and is ideal for use on general details in normal exposure areas.

    Traditional Lead trays are available in all the available cavity tray options below:

    Horizontal Trays
    Stepped Brickwork Trays

    To order our Performance Range trays, take advantage of our free take-off service where our in-house specialists will advise the right type and quantity of trays for the project, simply ask for the lead replacement option upon enquiry. For quoting stepped trays, the pitch of the abutment is required.
