Most pigments are accumulated by specialized cells, termed pigment cells, derived early in embryonic development either directly from the neural plate (e.g., pigmented retinal epithelium (PRE) and the pineal organ pigment cells) [1] or from the neural crest [2] and [3] .
Both the fascia and soffit are part of the exterior of the home and should be painted every 5-7 years, just like the exterior of a home. It is very common for the fascia to rot in older homes if it isnât painted often enough.The paint protects the fascia and soffit from the natural elements of weather.ain gutters are attached to the fascia, but an easier way to describe where the fascia is located is to say that it is what the Christmas lights are attached to. The fascia can be made up of any type of wood and size (2Ã4, 2Ã6 or 2Ã8).
Once the roof is on you can start the fascia/soffit installation, ideally before the tiles or other roofing material go on. Common materials for the job include pine, ply, cedar, UPVC.ifferent finishes/variations of the soffit can be achieved more commonly flat plain plywood is used although tongue and groove boards can be used or even battens with a spacing in between. In that instance mesh is used to stop birds or anything else getting into the roof space.
