ROOFING
ADEKA®

What is ADEKA®?

ADEKA® is an innovative patented roof or façade system based on small pre-formed QUARTZ-ZINC® and ANTHRA-ZINC® elements featuring a unique locking key. This ingenious easy to install system allows long term weatherproofing for roofs.

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. ADEKA® is an ideal solution for all sizes of flat surface roofs. 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.

Areas of application

Pitched roofs with slopes from 25% (15°) or more.

Cold roof or warm roof

New construction or renovation

All climates. For mountain areas, additional waterproofing is necessary, for windy regions, please consult VM ZINC® Australia

Panel Dimension

Lozenge-shaped element measuring 400x400 mm.

Aspects

QUARTZ-ZINC®
ANTHRA-ZINC®

0.65 mm

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.
19 mm plywood ventilated by a 40 mm ventilation air gap. Air inlet and air outlet are required at the ridge and at the eaves.
An additional waterproofing membrane may be required in heavy rain areas. Please consult VM ZINC® Australia.
Light weight (750g) and 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®.

Installation

1	ADEKA® is laid on 19mm 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.
