Petersen Brothers offers P-99 with a film covering as well as a Paper option. Non Glare P-99 acrylic sheets minimize glare and reflection. P-99 has a matte finish on one side to reduce glare that has a popular use for artwork and framing. The matte finish diffuses light striking the surface which helps to reduce glare. For best results, the sheet must be placed against or a small fraction from the picture or artwork.
