INTRODUCTION Catalog Prodema Prodex

PRODEX HPL EXTERNAL facade cladding

PRODEX HPL facade panels are a construction kit for ventilated facade cladding consisting of natural wood boards and an appropriate substructure. Each panel consists of a high density bakelite core, covered with a natural wood veneer with a surface coated with synthetic resin and an external PVDF film that provides greater durability to the panels, with anti-adhesive properties that protect the panel from solar radiation, atmospheric agents, dirt and attacks by chemical products (anti-graffiti). Due to its high resistance, it does not require the typical maintenance of other types of outdoor wood.
PRODEX veneered panels are unique, no two are the same, each grain is different, which explains the difference in shade between them and gives them a natural and authentic appearance that can be appreciated in the reflection of light on the wood fibers.
At Prodema we have invested a significant part of our resources in continuous improvement of the quality of our products, subsequently obtaining various certificates of tests carried out in independent laboratories.

This is because our philosophy of continuous improvement obliges us to obtain the most demanding quality certificates, such as the ISO 9001 quality management standard.

TECHNICAL DATA SHEETS Prodema Prodex HPL facade boards

BEFORE INSTALLING THE PRODUCT Prodema Prodex HPL wood-like

RECEIVING THE PROdema MATERIAL.
Check the condition of the shipment:
• In case of visible damage, leave details on the carrier’s waybill.
• In case of hidden damage, report it within 72 hours.

No claims for shipping damage will be accepted if any of these instructions are not followed.

HANDLING AND STORAGE of Prodema boards.

• PRODEX panels must be stored in a closed and air-conditioned room, at an ambient temperature of 10–25º C and air humidity of 30–70%.
• It is recommended to store PRODEX panels in their original packaging until installation. In the event that it is necessary to repack any panel, this should be done in the same conditions as in the original packaging.
• After opening the packaging, it is recommended to remove only those PRODEX panels that will be installed immediately. The remaining panels must be stored in the same conditions in their original packaging.
• PRODEX panels cannot be stored vertically, only horizontally on a pallet with supports
< 800 mm distance. Improper storage can cause deformation of the panels.
• The floor under the pallet must be free of materials and contaminants that can affect the stability of the pallet.

• During transport, PRODEX panels must be properly secured as they easily move when stacked, which can damage them. They must always be placed horizontally on a flat surface. • It is recommended to avoid exposing both sides of the PRODEX panel to different humidity and temperature conditions. When
PRODEX panels are fitted with fixings (such as hidden fixing clips), they must be stored face to face; back to back, using wooden or plastic supports placed between the panels at a maximum distance of 600 mm.
• These instructions also apply to cut panels.

RANDOM PLACEMENT OF PRODEMA HPL FACADE PANELS

PRODEX facade panels are manufactured from natural wood, therefore they may show differences in shade. Before production and installation, it is recommended to mix the panels in order to obtain an even distribution of shades throughout the facade. The following steps are described in detail below:
1. Number all pallets 1, 2, 3 etc. – The pallets must be stored throughout the production/installation process
in accordance with the requirements described in section 2.2.

2. Open pallet no. 1 and remove two panels – Place these two panels on a flat pallet, maintaining a maximum distance of 800 mm between the supports.

3. Turn over the third panel from pallet no. 1 without removing it from the pallet.

4. Close pallet no. 1 and store it in accordance with the packaging conditions given in section 2.2.
5. Repeat the same process with the remaining pallets, selecting them in random order until 10 to 20 panels have been removed. For example, if there are 20 pallets, remove panels from numbers 1, 8, 13, 15 and
20 or in another random order.

6. Mix the 10 to 20 removed panels and install them within 2 to 3 hours of removing the first panel.

7. Repeat the first six steps until all panels have been installed.

PRODEMA PRODEX Wood-like PANEL MODULE SIZE

Depending on the module size chosen for the façade, the aesthetic effect in most cases
is summarized as the following two options:
A. Installation of battens.

B. Installation of full-size panels or large modules.

 

 

Natural wood will always show differences in shade between panels. This difference in colour between
panels is more visible when installing large-sized panels (photo on the right). However, the difference in
colour will be minimised when smaller-sized panels are used (photo on the left). This is most noticeable
only in the Rustik and Pale colours. If you wish to see smaller colour differences, a control sample
should be sent with your material order. We will then make every effort to produce panels with a more uniform colour,
although there will always be variations.

PRODUCTION of Prodema Prodex facades

RECOMMENDATIONS FOR CUTTING PRODEMA PRODEX facade panels

The panels must be cut to square before cutting. Cuts on external panels must be made using tools with a material hardness of K – 05 and K – 01 (tungsten carbide / Widia), must be well sharpened and overheating must be avoided in any case.

A. SAW
Types of saws and blades:

Circular saws for wood made of hard material (Widia tip) or saw blades designed for HPL boards
(high pressure laminate).
Blade parameters depending on the type of tool:

DIAMETER     TEETH       SPEED     BLADE THICKNESS   TYPES OF TEETH

(mm)                  (z)            (rpm)                    (mm)

300                    48            4000-6000                    3.2                      Alternate bevel teeth (1)

250                40 / 48    4000-6000                  3.2                        and trapezoidal (2).

190                    30        3000-3500                    2.2

Positioning the Prodema panel

The saw blade must always start cutting from the front (face) side of the panel.
• Table saw: the front side of the panel must face up.
• Hand saw: the front side of the panel must face down.

Cutting blade height:

To obtain a clean cut, we recommend that the blade height is 1-2 cm above the surface of the panel.

After cutting the Prodex Prodema HPL board:

After cutting (cutting, drilling, edge grinding, if required), no other finishing or protective processing is required. Uneven edges can be smoothed with sandpaper.

B. CNC Prodex panel

The PRODEX panel can be made using numerically controlled (CNC) machines. Make sure that the bits are always well sharpened.

Recommended speeds when cutting Prodema Prodex facade panels:

• Cutting speed: 16,000 rpm.
• Feed speed: 4 m/min.
It is very important to avoid overheating the machine. The speeds recommended above must be monitored throughout the production process to ensure optimal results.

C. ALTERNATIVE SYSTEMS

In addition to the systems already mentioned, there are other processing options. Not all of them are compatible with the material.
• Water jet cutting: this system is compatible with PRODEX panels, however it is advisable to carry out a test beforehand to adjust the parameters.
• Laser cutting: this system is not recommended for use on PRODEX panels, as it will blacken and burn the wood veneer

DRILLING RECOMMENDATIONS Prodema Prodex

PRODEX panels are drilled using hard metal drills or steel drills with tungsten carbide tips (Widia) with a cutting angle greater than 100º. Drills for perforating metal can also be used.
To avoid chipping the material to be drilled, it is best to use a support plate under the panel to obtain a clean hole (see figure 1). If a support plate is not used, the finished surface of the panel will face upwards (see Figure 2)

Drilling speed recommendations:

• Cutting speed: 16,000 rpm. /min.
• Feed speed: 4 m/min.

NOTE: Should only be used as a reference point as these will vary from tool to tool.

INSTALLATION

PRODEX PRODEMA PRODUCT

GENERAL

PRODEMA VENTILATED FACADES

Did you know that… the use of a ventilated façade is essential for the installation of PRODEX panels?

To ensure good performance of this type of panel, it is very important that the humidity and temperature differences between the two surfaces are minimal. A ventilated facade has several advantages over a conventional facade:

Waterproofness to rain of ventilated facades.
A ventilated facade provides better water resistance to rain and prevents water from entering
the air chamber.
• Ensures good diffusion of water vapor from the interior of the building to the outside.
• A ventilated facade generates constant air ventilation and prevents
stagnant moisture or damp insulation.
• Reduces thermal bridges to a minimum

Improved acoustic insulation
• Thermal insulation
Generates energy savings of up to 50%* by absorbing less heat in the summer and dissipating less heat in the winter.
• Easy assembly and disassembly and a good solution for renovations

In summer or during hot weather, the sun shines on PRODEX panels instead of the building. This solar radiation heats the air in the air chamber, generating a “chimney” effect due to the change in its density. The ventilation created in this way prevents heat from accumulating on the facade, which, together with thermal insulation, is an ideal combination protecting the building from atmospheric factors.

In winter or during frosts, the ventilated façade acts as a heat accumulator, because the air chamber supports the thermal stability of the system. This ventilated façade construction system, together with thermal insulation, prevents heat loss from the building.

* Depending on the direction in which the building faces, the insulation used and the number of doors, windows, etc.
Did you know that… a ventilated façade requires unobstructed, continuous airflow to ensure proper performance?
• The airflow space behind the panel must be at least 20 mm. Please note that national or local regulations must be observed.
• Leave a 20 mm opening at the top and bottom of the façade, as well as at door and window openings. This is critical to ensure the required airflow.
• The substructure used to create the airflow space must be installed in a vertical direction. If conditions require horizontal strips, they will require drainage holes allowing 20 cm2/m on facades up to a height of 1 m and 50 cm2/m on facades above 1 m. _elewacje_wentylowane-27.jpg”>SUPPORT

EXPANSION JOINTS Prodex Prodema boards

DIMENSIONAL STABILITY

PRODEX is finished with natural wood veneer and will be subject to dimensional changes due to temperature and humidity fluctuations. The maximum dimensional change in the longitudinal direction is 0.30%, and in the transverse direction 0.60%.

These minor dimensional changes do not affect either the aesthetics or the performance of the panels. It is therefore very important to take into account the expansion joints indicated by Prodema.

PRODEX is resistant to steam, water, snow and ice. However, we do not recommend permanently or for long periods of time immersing the panels in any of these conditions, as a darker colour may appear along the edges of the panel surface.

SUBSTRUCTURE OPTIONS Ventilated facades

Since PRODEX panels require a ventilated facade for installation, the battens used as a substructure
must be installed vertically. The attachment of the battens to the substrate must be done using fasteners suitable for the material used.

The substructure system must comply with local wind load requirements and building regulations.
The installation method, thickness and dimensions of the panel will also be taken into account. Finally, the substructure system components must be protected against corrosion, regardless of the material or type of installation.

Metal subframe. ALU brackets

In rainy or humid areas, galvanized steel or aluminum strips are recommended. In coastal areas, we recommend stainless steel or anodized aluminum strips.

Wooden subframe Wooden substructure Prodema ventilated facades.

This type subframe requires treated timber. PVC or closed cell polyethylene foam sealant is required between the batten and the back of the panel to act as a moisture barrier.

A universal bracket can be used if necessary to correct unevenness in the surface alignment.

MINIMUM NUMBER OF SUPPORT POINTS FOR A PRODEMA HPL PANEL

The panel should be supported by the maximum area of ​​the subframe element, regardless of the system. According to the diagram, at least 3 supports are required, vertically and horizontally.

If the width of the panel is within the specified dimensions (as shown in the diagram below), only two support points are required.
EXCEPTIONS

CONICAL AND TONGUE HEAD SCREWS for ventilated facades

Prodema does not allow the installation of tongue-and-groove panels on external facades. This system is
fixed with countersunk screws that prevent the panels from moving, and they are also
screwed only around the perimeter of the female connector, not the male connector; which is insufficient for the PRODEX panels to function properly according to our recommendations.

INSTALLATION SYSTEMS. Prodema Prodex elevation installation

PRODEX VISIBLE FASTENING WITH SCREWS OR RIVETS

This type of installation involves securing the PRODEX panels with exposed screws or rivets. The screws and rivets* are made of stainless steel and can be ordered in a colour that matches the panels.

The distance between screws or rivets*, both horizontally and vertically, varies depending on the thickness of the panel.
• Each element must have at least 3 support points in each direction.
• Never use countersunk screws to secure PRODEX.

* Rivets should only be used with metal subframes, not with wooden subframes.

Distances of screws and rivets from the edges of Prodex Prodema panels

Screws and rivets* must be screwed at a distance of 20 mm (minimum) to 40 mm (maximum) from the edge of the panel.

Types of fasteners

Screw: SFS – TW – S – D12 – 4.8 x 38 (varnished or rolled)

* Rivets are used only for metal subframes, not wooden ones.

 

Metal strips. Aluminum facade structures

• SCREWS:
SFS – SX3 – L12 – 5.5 x 32 – IRIUS head (painted or rolled).
SFS – SX3 – D12 – 5.5 x 30 – TORX head (lacquered or rolled).

• RIVETS*:
SFS – AP16 – 50160 (painted or rolled).
SFS – AP16 – 50180 (painted or rolled).
SFS – AP16 – 50210 (painted or rolled).

Diameter of screw/rivet holes

The holes for exposed fastening screws must be drilled 3 mm larger than the diameter of the screw shank. This allows the panel to expand and contract freely.
Exception: the geometric center hole is permanently fixed and will be the same size as the screw shank. This fixed point ensures that the movement of the panel is evenly distributed.

Follow the drilling instructions.

Screw/rivet position during Prodex Prodema panel assembly

It is important to screw the screw/rivet into the center of the hole and make sure the fastener head is completely flush with the panel surface.
