Our UPVC fascia does not require a backing board - they are a straight replacement for old timber fascias, as they are nailed directly onto the rafter feet.These boards are used on both new builds and refurbishment projects, the latter of which is the reason you may hear them be referred to as replacement fascias.Our agate grey fascia is available in a wide range of widths including 150mm, 175mm, 200mm, 225mm, 250mm andamp; 410mm.The return leg on the board is slightly rebated to accept a soffit board.For more information on how to construct a box end board please take a look at our guide on how to make a fascia box end or our video below;
