What is Adeka for facade?

Adeka is an innovative patented facade system based on small pre-formed QUARTZ-ZINC,  ANTHRA-ZINC and PIGMENTO elements featuring a unique locking key. This ingenious easy to install system allows long term weatherproofing for facades.

Adeka is a complete system which includes a full range of flashings to handle all facade situations.

Adeka is an ideal solution for all sizes of flat facades. Less than 10 Adeka elements are needed to cover 1 m2 and the easy assembly (no mechanical tools necessary) of Adeka improves zinc laying time.

Characteristics of this technique
A polystyrene wedge is bonded to the underside of the Adeka and ensures the rigidity of the panel.
Aesthetic aspect of diamond shaped elements.

15 mm plywood ventilated by a 20 mm ventilation air gap. Air inlet and air outlet are required at the top and bottom.

Light weight (750g) and is suitable for all types of structures.

Adeka elements are weather resistant thanks to the 5 cm overlap, raised edges at the top, and dropped edges on the bottom, and a polystyrene wedge bonded to the underside of the Adeka.

All necessary flashings shall be minimum 0.7 mm thick in Zinc plus. All other fixing accessories should be in accordance with the design recommended by VMZINC.

What is Zinc plus?

Zinc plus is VMZINC coated on the underside with a protective layer (VMZINC patent).

  • Allows the use of an incompatible roof deck.
  • Zinc plus products can be bent, folded or profiled without any surface change (similar to VMZINC products) and thus allow the exact methods of laying.

  • Flat facades.

The support must be:

  • 15mm plywood rigid and continuous, with a minimum 20mm ventilation cavity that is unobstructed,
  • Rest on at least 3 bearing structure elements,
  • Have no protruding elements on the support.
1 Adeka is laid on 15mm plywood and a separation membrane (i.e. tyvek) should be laid before installing the panel. For 20° - 30° (36% - 60%) roofs use a continuous deck. For roofs steeper than 30° (60%) or facades, Adeka can be laid on battens with 203 mm centre-to-centre span. The support must be continuous for 40 cm adjacent to special features such as corner or bottom flashing.
2 Mark out lines on the deck every 56 cm (or 28 cm) at right angles to the baseline. These will be used to line the Adeka elements up with the alignment guide on each element.
3 Begin laying from the eaves up, folding the locking key under the fold of the eaves flashing.
4 Insert the Adeka element via the locking key into the appropriate grooves made in the lower elements. Then fix each Adeka onto the wooden deck in the pre drilled holes.

Around flashings, Adeka elements may be cut to size using shears.

In some cases, you will need to drill additional screw holes into the re-sized Adeka elements. Waterproof by placing a neoprene washer on the screw. Resized Adeka elements can also be fixed using one clip or several additional clips.

For Adeka elements that overlap with flashing accessories, cut away the polystyrene wedge so that it does not overlap the flashing. Recommended Fastenings Fastener for Adeka: wood screws 300 Series Stainless Steel.

All fasteners have to be countersunk in pre-punched holes in order to eliminate the risk of contact and abrasion between the fastener head and the panel. Fasteners shall be selected to resist all negative design load requirements. Minimum pullout strength: 50 daN.
