SFS DRALL-FIX insulation spirals spring steel znb U120

The Drall-Fix© fastening system is particularly suitable for all insulation boards made of mineral fibre materials (glass and rock wool). Façades, pitched roofs, flat roofs, floors and ceilings are possible areas of application.

The Drall-Fix© fixing system consists of the Drall-Fix© steel spiral and the corresponding fixing device. The Drall-Fix© steel spiral is inserted into the device, then placed on the insulation board and fixed in place with a manual push. With this fixing system, the second layer of insulation board is quickly, easily and perfectly fixed to the first layer. The Drall-Fix© fastening system is particularly suitable for all insulation boards made of mineral fibre materials (glass and rock wool). Façades, pitched roofs, flat roofs, floors and ceilings are all possible areas of application. The screw-in depth in the second layer must be at least 45 mm, depending on the density. The special shape of the Drall-Fix© spiral type U fulfils the higher requirements in terms of insulation board thickness and holding strength.
Leading manufacturers of insulation boards such as Flumroc, Knauf, Rockwool, Sager and Saint-Gobain Isover recommend Drall-Fix® for quick and easy fixing.
