Heraklith DDS plus concrete screws are specifically suited
for mounting wood wool boards directly to normal concrete
(2000-2600 kg/m3). Comprehensive international fire testing
has shown that combining DDS plus screws with the Heraklith
Tektalan A2 or the A2 Decorative panel results in excellent
performance in fire-resistant applications.
The concrete screw consists of steel with a corrosion
class C3. The screw can therefore be used in an outdoor
environment that is not directly exposed to the elements.
The screws come standard in the colours white and nature
tone (RAL 1015).
