Installation of HIGHLUX® multi-skin sheets

Barrel vault

HIGHLUX® multi-skin sheets are modified for impact resistance and can be installed cold-curved. They are suitable, for example, for skylight domes in industrial roofs. A minimum radius of 150 × sheet thickness must be observed.

Transportation + storage

HIGHLUX® multi-skin sheets are protected against sunlight, UV radiation and moisture during transportation by PE film and a white PE cover (recyclable). Do not remove the outer packaging when storing outdoors. Cover opened pallets with white colored PE film. Keep the ends of the boards closed. If the panels are shortened, the end faces must be protected again in accordance with the factory measures. A maximum of 3 pallets with standard equipment can be stacked on top of each other.

Fire behavior

HIGHLUX® multi-skin sheets are classified as normally flammable (DIN 4102-B2). Take the same precautions against flames and high heat as apply to wood and other combustible building materials. Only use multi-skin sheets in accordance with the applicable building guidelines and the manufacturer's instructions.

Walking on

For your safety and to prevent damage to HIGHLUX® multi-skin sheets, walking on them is only permitted on padded wooden planks or similar, which are preferably positioned above the load-bearing elements of the substructure and are thick and wide enough to prevent sagging. Fixed, padded ladders or scaffolding are required on steep slopes.

Sawing

The best saw cuts are achieved with carbide-tipped saw blades. High-speed circular saws should be used. The panel must be clamped firmly to prevent fluttering. When cutting to width on all sides of the bar, appropriate reinforcement profiles should be fitted. Please contact your supplier for more information.

Drilling

As the point-by-point fixing of HIGHLUX® multi-skin sheets is problematic, we advise against drilling. Please request further information from the supplier.

Roof pitch

We recommend installing the HIGHLUX ® multi-skin sheets with a roof pitch of at least 5°, corresponding to 9 cm/m, so that the self-cleaning effect of the rainwater run-off takes effect and any condensation water in the chambers can drain away better. The sheets must be secured against slipping. The direction of the web must always be in the direction of water flow. Irrespective of the roof pitch, the customer must ensure that there is an appropriate seal to the wall.

Internal shading

When using interior shading, it is essential to ensure that no heat build-up occurs. Shading (roller blinds, fabric panels, etc.) should be white and compatible with acrylic glass. We recommend maintaining a minimum distance of 20 cm from the sheet. Sufficient ventilation must be ensured between the sheet and the shading, otherwise heat build-up can cause cracks.

Expansion tolerance

HIGHLUX® multi-skin sheets expand when exposed to moisture and heat. An expansion clearance of + 6 mm/m sheet length and width must therefore be provided. The natural expansion of the sheets can cause cracking noises. This does not affect the serviceability of the boards. Suitable profiles with rubber lips can reduce the noise. Please contact your supplier for more information.

Substructure

To prevent localized heating of the multi-skin sheets, the surfaces of the substructure facing the multi-skin sheets should be white or light-reflecting. The substructure should be torsion-free (use glulam beams for timber constructions). In addition, a gap of at least 20 mm must be maintained between the sheets and the cross supports. The substructure is usually treated with varnish or lacquer. To prevent the vapors from attacking the boards, the substructure must be allowed to flash off for a few weeks before installation.

End closure

HIGHLUX® multi-skin sheets are slightly permeable to water vapor. Condensation may occur in the sheets. The sheets must be sealed tightly at the top - we recommend an aluminum adhesive tape and a suitable aluminum sealing rail. Suitable profiles should be used on the lower end face to allow condensation to escape and prevent dirt from penetrating. We recommend a suitable aluminum end rail with a drip nose.

Compatibility

Auxiliary materials for assembly, cleaning agents and solvents, sealing materials, etc. can cause stress cracking even after a long period of time. Ensure that these are compatible with acrylic glass. Visible profiles and rubber cover strips should also be light-colored, preferably white. Ask your specialist dealer for recommendations on sealants.

Protective film + adhesive tape

HIGHLUX® multi-skin sheets are protected against scratching at the factory with PE film. These protective films must be removed after the panels have been installed. Protective film that has not been removed is very difficult to remove later. HIGHLUX® multi-skin sheets are sealed at the front with adhesive tape, which should generally also be removed before installation.

Cleaning

Plastic panels should be cleaned at least once a year, depending on how dirty they are. Clear, lukewarm water with a mild household detergent that is compatible with acrylic glass is suitable for cleaning the surface. To avoid scratches, do not use abrasive materials. Only use cleaning agents and additives that are compatible with acrylic glass. Then rinse with clean water.

No Drip

HIGHLUX® multi-skin sheets are supplied from the factory with a special functional coating on one side ("No Drip"). This coating ensures that rainwater runs off in a smooth film and does not remain on the sheet as drops.

Laying direction:

• No Drip to the outside (top) > water-repellent (primarily for open construction)
• No drip inwards (downwards) > reduced drop formation in the event of condensation
