The requirements for installation of insulation on the roof and fa├žade requires specially designed fastener. With the help of the proven double thread fasteners TWIN-UD, the projects can be economically planned as well as easy, fast and secure installation. The double thread permanently connects the counter battens reliably with the supporting structure and thus prevents damage to the insulation. The special geometry provides a comfortable and damagefree installation. The special coating offers a high corrosion protection, even under special environments and materials.
