What is Adeka for roofing?
Adeka is an innovative patented roof or facade 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 sq. and the easy assembly (no mechanical tools necessary) of Adeka improves zinc laying time.
|Useful dimensions||400 X 400 mm|
|Centre to centre||205 mm|
|Packaging||24 Adeka / 2.7 sq pack|
Characteristics of this technique
A polystyrene wedge is bonded to the underside of the Adeka and ensures the rigidity of the panel.
An additional waterproofing membrane may be required in heavy rain areas.
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.

|Aesthetic of transverse line of offset joint,|
|Ingenious locking key system making it easy and fast to install.|
- Pitched roofs with slopes from 25% (15°) or more.
- All climates. For mountain areas, additional waterproofing is necessary, for windy regions, please consult VMZINC Asia.
Adeka is laid on 19mm plywood or galvanized steel sheet. 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.
Minimum pullout strength: 50 daN.
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.
Begin laying from the eaves up, folding the locking key under the fold of the eaves flashing.
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.
