Eurotec's Topduo roof screw offers a wide range of applications in timber construction - especially for above-rafter insulation on pitched roofs. It provides reliable fastening of both compression and non- compression insulation, contributing significantly to the stability and durability of the structure. With its high pull-out resistance, the Topduo is also suitable for various other timber construction applications. The screw has a double thread and is available with disc or cylinder head.
The Topduo roof screw has a reduced torque, making it easier to install. It also protects the material as the design of the screw ensures a reduced splitting effect. Another feature is the improved 'bite' of the screw - this ensures a secure hold and easy handling.
