Pvb Laminated Glass Uv
Laminated safety glass made with butacite polyvinyl butyral pvb interlayer trosifol sound control.
Pvb laminated glass uv. Saflex is a plasticised polyvinyl butyral pvb film that bonds with glass under heat and pressure to form laminated safety glass. Single pane clear glass with a tdw of 0 84 allows most of the uv and visible energy to come through into the room offering very little protection. On the other hand laminated glass can block over 95 of the uv energy while allowing most of the visible light through. Laminated glass can incorporate various combinations of clear and tinted glass transparent or coloured interlayers as well as a range of high performance coatings.
Laminated glass is a type of safety glass that holds together when shattered in the event of breaking it is held in place by an interlayer typically of polyvinyl butyral pvb ethylene vinyl acetate eva or thermoplastic polyurethane tpu between its two or more layers of glass. The other key advantage to laminated glass is that it blocks 99 percent of the uv light transmission has sound reduction properties it can be cut and its edges can be polished after laminating and lead times are generally faster because most glass shops stock laminated glass. Sgp interlayers are a stronger ionoplast based interlayer that can be used to create stronger architectural glass constructions and offer the same level of uv protection as a pvb interlayer. The saflex interlayer sandwiched between the layers of glass is responsible for the enhanced performance properties of laminated glass.
Pvb polyvinyl butyral is a laminate used to provide strength toughness optical clarity and flexibility to glass. 76mm pvb or thicker will meet the requirements for cpsc 16 cfr 1201 category i and ii ansi z97 1 class a and b and can cgbs12 1 m category i and ii. Ultravue laminated glass this high performance glazing solution delivers an exceptional viewing experience with its nearly invisible finish and its crystal clear color neutrality combined with superior safety protection and security to minimize risk of injury and safeguard artwork in the event the glazing is broken or damaged. Laminated glass made with 030 in.
In other words the penetration of uv a light is almost entirely prevented by the pvb film. Pvb laminated glass is manufactured by permanently bonding one or more polyvinyl butyral pvb interlayer between sheets of clear coated or tinted glass under heat and pressure. Conventional polyvinyl butyral pvb in laminated safety glass blocks out almost all ultraviolet uv radiation up to a wavelength of about 400 nanometres nm.
