Review: Really easy to cut. - Panel arrived 0903 and was fully fitted by 10:45 This is plastic faced on front and back, has a polystyrene infill with thin ply board as a centre strengthener. It makes it very light and easy to handle. Only one cut was required on the width. Easily done with hand saw -a five minute job. The time delay was in cleaning the old door frame, sorting out tools and tidying up! Make sure you get the correct thickness when ordering. Easily recommended as far cheaper than full door replacement.
