Blocks up to 99% of harmful UV rays up to 400 nm*

In architectural design, natural light is visually appealing because it’s dynamic. It’s emotionally appealing because it connects us with the outside world. And it’s practical because many sustainable designs now call for effective daylighting. But natural light also brings damaging UV rays. 
With Saflex UV PVB interlayers, you can design to let sunshine in without worrying about UV radiation prematurely fading drapes, curtains, carpet, furniture, hardwood floors, wallpaper, photographs, framed documents, artwork, and anything else your clients like to show off indoors . . . including their skin**.
Conventional Saflex PVB interlayers have a 99% UV screening capability to 380 nm. Saflex UV, however, screens 99% up to 400 nm. Useful for many applications, this level of UV protection is ideal for museums, storefronts, libraries, and switchable/smart glazing with sensitive layers such as liquid crystals.  

Saflex UV has the capability to meet or exceed many regulations for laminated safety glazing when properly selected, laminated, and installed. Plus, Saflex UV is specifically formulated to provide exceptional durability when exposed to natural weathering; natural and accelerated exposure testing has indicated exceptional color fastness, durability, and resistance to delamination when exposed to heat and humidity.
Saflex UV interlayers also provide all the benefits of safety glazing, glass shard containment, structural integrity, sound abatement, security, and storm protection when used in the proper configurations.
