Characteristics
Points
MR.Bond
A1 class material
non-
combustible.
1
FIRE REACTION
0
The plastic core prevents this material from attaining the same fire reaction rating. Combustible material.
As this is an A1
class material,
It may be used
in all states and
building types.
1
INTERNATIONAL
COMPLIANCE
0
In certain countries
the material is subject
to restrictions due
to its aptitude
to propagate flames.
Scoring:
unnecessary.
This means
savings on
working costs.
1
MECHANICAL
WORKING
0
Scoring: necessary.
It involves
working costs.
At the moment of elimination all scrap can be reused.
1
INTRINSIC VALUE OF PRODUCT/ RECYCLING
0
Elimination of the material involves costs because it is not biodegradable.
In the long term it is cheaper than MR. Bond.
1
PURCHASE COST
0
In the long term it costs much more than DMAX.
Coverage required only for aluminium and paint (PVDF Kinar 500 with 30 year guarantee)
1
GUARANTEE
0
Guarantee must cover several materials, including plastic and adhesive, increasing the risk of client liability in the event of dispute.
Strong resistance that prevents the surface of the material to suffering damages.
1
IMPACT RESISTANCE
0
The internal plastic core absorbs the impact traumatically and damage will be evident on the surface.
Good resistance
DRILLING PENETRATION
Low resistance
Unlimited: more than 2000 colours
1
COLOUR RANGE
0
Limited, the range of colours cannot compare with Otefals range.
DMAX is made using exclusively 5000 aluminium magnesium alloy.
1
ALLOY USED
0
Different alloy types, including 1000 and 3000 series. They dont guarantee the same mechanical resistance as 5000 series.
42% more resistant than the composite material.
1
WIND PRESSURE
0
The inner plastic core is not resistant to bending
Does not influence coefficient of heat transmission.

However, while it would be difficult to list
all the situations in which composite materials
cannot be used, it can be said that they may not be used wherever incombustible materials
are required.
According to European standards DIN EN 13501(which may vary slightly
from state to state as a result of incorporation into national legislation, but
which will be harmonised in the foreseeable future), incombustible materials
must be used in all buildings taller than 20 metres(or less, depending on
whether fire escape staircases are installed) and in all public buildings, such
as schools, hotels, hospitals etc.,
irrespective of height.
For example, for a school or hotel in Italy, which must be equipped with fire escape routes leading, in the majority of cases, to a fire escape staircase, the Ministerial Decree of August 19th 1996, concerning places of public entertainment (which, in the absence of specific legislation is also applicable to other public buildings, such as schools) states that the outer wall of the building against which the staircase and relative fixtures are installed must meet fire resistance requisites of at least REI 60 for a width equal to the projection of the staircase plus 2.5 metres one each side. Clearly, any such wall built using inflammable external panels
could never attain a rating of REI 60. Moreover, it is becoming increasingly difficult to
obtain fire insurance for private buildings clad with
inflammable materials.
The impact test measures impact resistance of an aluminium panel.
Impact resistance is high in solid aluminium,
because the impacting part knocks against a 2/3 mm metal sheet, which exercises a high resistance to the movement.
Solid aluminium is resistant to puncture penetration test:
try to drill a 3 mm sheet of aluminium plate, its quite difficult penetrating the thick metal!
