Ogee fascias are more decorative than standard fascia boards with their elegant feature grooves and concave moulding along the bottom edge of the board.Our 18mm Ogee replacement fascias are so called because they need no backing board - they are a straight replacement for old timber fascias as they are nailed directly onto the rafter feet.The name is a little misleading as nowadays these boards are most commonly used on new build projects.Available in sizes from 150mm to 350mm, replacement fascias should be fixed using 2 x 65mm polytop nails at each rafter (maximum spacing 600mm).The return leg on the board is slightly rebated to accept a soffit board.
