VulcaLap® aluminium rainscreen comprising patented Aluminium is highly recyclable. Recycling scrap aluminium

85% of the aluminium used in buildings today comes from

Fire performance
VulcaLap® aluminium has been fire tested in fully finished
state to EN ISO 13823 and EN ISO 1716 giving combined
test result: EN 13501-1: 2007+A1: 2009: Reaction to fire
A1 FIRE RATED, ANODISED FINISHES classification: A2-s1,d0 for the complete RAL spectrum
and wood finishes; A1-s1,d0 classification for anodised
finishes. VulcaLap® can be used in all situations requiring
limited combustibility, including rainscreen to buildings
over 18 metres high. For fire safety the insulation, breather
membrane and fixing sections must also comply. Enhanced
fire resistance can be achieved by using Fireshield
intumescent breather membrane shown on page 7.

Colours and finishes
Aluminium has a wide range of finishes available.
For the best long-term performance of powder coat and
anodised finish the cladding should be cleaned at max-
imum of 6-month intervals. For harsh industrial environ-
ments, cleaning should be carried out every 3 months.
Refer to our maintenance recommendations on page 9.
