Corner trims are used to hide the 10mm expansion gap that should be left between two boards at the corner of the eaves.To enable the system to expand and contract correctly in a different range of temperatures, one side of any joint or corner on any PVC fascia installation should be glued to the board and the other side should be sealed with low modulus silicon, which allows movement within the joint.Double ended corners can be cut to size with a standard hacksaw or fine toothed saw.
The Black Ash Woodgrain Fascia Board External Corner would be the best fit for exterior architectural applications that require durable, low-maintenance, and aesthetically pleasing options.
