ShadowLine detail (also known as Negative detail) adds a modern finish to door jamb liners. The timber jambs are manufactured so as to aid the builder in finishing the jamb detail with a small 10 x 10mm rebate around the jamb liners. This popular detail is made easy with a ShadowLine unit.
If timber jambs are used, the jamb can be supplied with a non-standard return. Wall linings are run up to within 10-13mm of this return to create a negative detail. If required, a ‘Z’ mould can be used.
If aluminium jambs are used then two layers of plasterboard are required to create the detail. The first acts as a packer (13mm) and the second creates the detail. The jambs are supplied with a reduced face width so that the overall jamb width matches the finished wall thickness.
