TF02 dentils are installed at eaves level on homes being built to mimic Victorian detailing. These are our most popular dentils manufactured in a tough white duropolymer.
These are usually installed with the 120mm section against the wall and the 105mm length projecting along the underside of the soffit. TF01 dentils are typically spaced at 600mm centres, but existing dwellings may dictate otherwise. In some regions dentils may have originally been fitted in a "hit and miss" pattern. In effect there would be one dentil, a 3 inch (75mm) gap to the next one and so on around the entire building.
Each dentil should be fixed from above using a suitable screw (not supplied) prior to the roof being felt and battened. Retro-fitting on PVCu soffits can be achieved by using super glue and activator.
