Tolerances +10mm -0mm (EN 438-6,5.3) Panel formats
are production formats. If exact dimensions and angles
are necessary, we recommend an all-sided blank.
Edge Processing
To mill bevels electric hand planes with bevel or bevel
grooves can be used or hand routers.
Expansion / Contraction
Max Exterior shrinks when it loses moisture and expands
when it absorbs moisture. Calculate: overall length ÷ 500
= change in length
Curved Max Exterior Panels
Top and bottom edge profiles (2mm thick) must be
pre-bent. Only sliding line fastenings are allowed (no
point fastenings). The straight ends and joints of the
exterior panels must likewise be edged. (U-profile,
H-profile).
Min. radius 3m(9'-10") and min. length 1.3m(4'-3").
Sealent
The use of sealant compounds must be avoided as they
can cause permanent staining to Max Exterior panels.

Panel Joints
To be minimum 8mm wide for vertical and horizontal
joints. The wider any joint, the less noticeable are
inaccuracies in width. Therefore typical joint width used is
13mm.
Panel Attachment Layout
Spacing of rivet fasteners to be spread equally on panel.
See below for edge distance and spacing requirements.
Ventilaton Cavity
The effectiveness of a pressure equalized system
depends on a clear minimum air cavity depth as
determined by building height. The cavity may not be
reduced by horizontal profiles or any stray objects such as
loose wind proofing layers, etc... Minimum cavity
thickness as per table below:

Ventilation Cavity Intake/Exhaust
Air cavity ventilation openings provided at the base and
top of the wall area and at any additional interruptions for
example window heads and sills.
Panel Attachment
For fixing onto aluminum subframe, use Fundermax
specified aluminum rivets. For fixing onto steel subframe,
use Fundermax specified stainless steel rivets. Rivet
saucer head is 15mm Ø painted corresponding colour
with Max Exterior panel. A EPDM washer gasket is
placed under rivet head to provide weather seal. For
wood subframe stainless steel screws will be provided.
Double span panel.

Max Exterior Panel Expansion/Contraction
To allow expansion and contraction between the
substructure and panels, all holes drilled in Max Exterior
are oversized from the rivets body diameter. In order to
hold up the panel, 1 rivet per panel is fixed by infilling the
oversized hole with an aluminum or stainless steel sleeve.
In addition to the fixed point, a loose point is placed in the
same level. Position of the fixed and loose points will be
determined on shop drawings.
Site Fabricating Panels
Avoid using tools which produce fine dust. Always work
out of the weather. Always drill/cut perpendicularly to the
panel surface. Use circular saw with straight edge with
dust extraction. For best cut use a Blad hard metal teeth
TF or diamond tipped saw blade. Use jig say for hole cut
outs in panel. Dust from fabrication must be removed
from panel surface immediately following cutting.
Site Storage
Max Exterior panels must be stacked horizontally on flat,
stable supports and supporting panels. The goods must
lie completely flat.
Cover plates must always be left on the stack. The top
cover should be weighted down. After removal of panels,
PE films must again be closed over tyhe stack. The same
applies, in principle, for cut-panel stacks. Incorrect
storage can lead to permanent deformation of the panels.
Max Exterior panels are to be stored in closed rooms
under normal climatic conditions. Climate differences on
the two surfaces of a panel are to be avoided.
With pre-installed fastening elements, therefore, care is to
be taken that the climatic effect is uniform on all sides.
Use intermediate layers of wood or plastic.
