The Swish Visual Assembler is an animated representation of the major fascia and soffit components. It shows their relationship to each other and how they fit together.
Notes
Fascia boards are available in a large number of colours, styles and sizes to suit most applications.Ventilation may be provided over the fascia or through the soffit (alternatives not shown).
Where 16mm and 25mm fascias are concerned, it is not necessary to use a backing board. Your guttering then fixes onto these fascias directly. When you are faced with a long run of materials, you should aim to leave an 8mm expansion gap at joints, and keep this in mind when your fascia and soffit joints are made between rafters. A4 marine grade stainless steel fixings are required when fitting the roofline.
