Tuffak® A Polycarbonate Sheet is the basic grade of a high-impact polycarbonate plastic sheet. Virtually unbreakable, Tuffak A sheet is 300-times stronger than single-strength glass, and significantly tougher than other transparent sheet materials of equal thickness. It's unlikely that Tuffak A sheet will break, shatter or chip when bombarded with thrown missiles such as rocks, bricks or bottles. Nor is it likely that this material will break when hammered, twisted or bent.

At the same time, Tuffak A polycarbonate sheets are light in weight, transmit 85% to 89% light in normal window thickness and have good weatherability. UV-stabilized Tuffak A sheets have good resistance to solar exposure for five to seven years in moderate climate. Such exposure over a wide temperature range does not affect its impact strength.

Tuffak A Polycarbonate sheets are supplied in colorless transparent sheets and in solar tints for heat and glare control. The material is available in standard sheet sizes ranging from 24" x 48" to 96" x 96" and 72" x 120", and in thicknesses from 0.060" to 0.500".
