DGZ, the wood screw that helps prevent thermal bridges and facilitates energy efficiency.
DGZ is the connector for hard, soft and façade insulation, CE certified according to ETA 11/0030. Available in two diameters (7 and 9 mm), it makes it possible to optimize the number of fasteners.
The cylindrical head is ideal for hidden insertion in the batten. DGZ is also certified in versions with flange head (DGT) and countersunk head (DGS).
The double thread makes it possible for the DGZ wood screw to fix the roof insulation package to the supporting structure without any interruptions, preventing thermal bridges and facilitating energy efficiency.
Certification specific for fastening on both hard and soft insulation. DGZ is also tested, certified and calculated on façade joists and with high density woods such as Microllam® LVL.
For design calculation, the MyProject software is available free of charge. It can be downloaded from our website and produces a personalised calculation report in just a few steps.
DGZ is made of carbon steel with bright zinc plated, and is ideal for use on wood-based panels, solid timber, glulam, CLT, LVL and high-density woods. Service classes 1 and 2.
