VMZ Adeka is an innovative patented roof or 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 roofs.
VMZ Adeka is a complete system which includes a full range of flashings to handle all roofing situations. It can be used for flat surface roofs with slopes of 25% (15°) or more. VMZ Adeka is an ideal solution for all sizes of flat surface roofs. Less than 10 VMZ Adeka elements are needed to cover 1 sq. and the easy assembly (no mechanical tools necessary) of VMZ Adeka improves zinc laying time.

Characteristics of this technique
A polystyrene wedge is bonded to the underside of the VMZ Adeka and ensures the rigidity of the panel.
Aesthetic aspect of diamond shaped elements.
19 mm plywood ventilated by a 40 mm ventilation air gap over a breathable anti abrasive building paper (Tyvek). Air inlet and air outlet are required at the top and bottom. An additional waterproofing membrane may be required in heavy rain areas.
An additional waterproofing membrane may be required in heavy rain areas.
Light weight (750g) and is suitable for all types of structures.
VMZ 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 VMZ Adeka.
All necessary flashings shall be minimum 0.7 mm thick in VMZ Zinc plus. All other fixing accessories should be in accordance with the design recommended by VMZINC.
What is VMZ Zinc plus?
VMZ Zinc plus is VMZINC coated on the underside with a protective layer (Umicore patent).
- Allows the use of an incompatible roof deck.
- VMZ 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.

- Pitched roofs with slopes from 25% (15°) or more.
- All climates. For mountain areas, additional waterproofing is necessary, for windy regions, please consult VMZINC.
The support must be:
- 19 mm plywood rigid and continuous, with a minimum 20 mm ventilation cavity that is unobstructed,
- Meet loading requirements in conformity with a minimum pull out strength of 50 daN for each clip,
- Rest on at least 3 bearing structure elements,
- Have no protruding elements.
VMZ Adeka is laid on 19 mm 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, VMZ 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.
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 VMZ Adeka elements up with the alignment guide on each element.
Insert the VMZ Adeka element via the locking key into the appropriate grooves made in the lower elements. Then fix each VMZ Adeka onto the wooden deck in the pre drilled holes.
Around flashings, VMZ Adeka elements may be cut to size using shears.
In some cases, you will need to drill additional screw holes into the re-sized VMZ Adeka elements.
Waterproof by placing a neoprene washer on the screw. Resized VMZ Adeka elements can also be fixed using one clip or several additional clips.
For VMZ Adeka elements that overlap with flashing accessories, cut away the polystyrene wedge so that it does not overlap the flashing. Recommended Fastenings Fastener for VMZ 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.
