It is a wide-headed plastic nail. When the thickness of the insulation board increases too much, it is necessary to use wide-headed but plastic-coated steel body nails (dowels). Plastic anchor body diameter is 10 mm. Plastic coated dowel body diameter 8mm with steel studs. It should be. It should be chosen to go inside. Dowel head 60mm. It should be. Dowels suitable for the insulation thickness and density to be used in exterior heat insulation sheathing applications should be used. Along with the insulation thickness, the wall structure where the application will be made is also important. The dowels used should be made of plastic. The surface connection must be in the length of "". Drill diameter should be at least 1 mm from the diameter of the dowel on solid application surfaces (gross concrete). It should be large (10mm. Dowel 11-12 mm. Drill) if the drill diameter is the same as the dowel, the dowel will not open on the filled application surface. On the surfaces applied with gaps, the insulation thickness and the holding area of the surface should be well calculated and an appropriate size dowel should be used. and dowel production is made in accordance with its density.
