Prestige tiles are made from a glass fibre mat, with a weight up
to 125gm/m2. This gives high mechanical strength, in excess of
any international standards. The fibre is pre-impregnated with
bitumen to eliminate moisture or cavities within the mat.
Further bitumen, which is carefully selected to ensure product
stability and resistance to temperature fluctuations is then
added, and the copper foil is laminated on top. A special
thermo setting adhesive is then applied, which sticks the
leading edges of the tiles down, and the material is then cut to
the shape r equired.

Prestige tiles are supplied as a tile strip of 3-5 tiles, depending
on the style, which is normally nailed directly to a timber deck.
The strip size is 1000 x 340mm. Full details of this, the
exposure or distance between the courses, and pack sizes are
shown in the data table.
The installed weight, including overlaps, varies from 8.5 to
17kgs/m2 depending on style, as shown in the data table. This
makes them suitable for lighter, more economic, structures.
Prestige tiles will quickly lose their bright appearance when
exposed to the atmosphere.The copper will weather through its
bronze tone to the eventual green patina, which in marine
atmospheres can take 5 years, but in more rural locations can
take over 20 years. A pre-patinated version of Elite and Compact
