I need to find a manufacturer of UV filtering glass. I realize regular glass filters UV below about 300 nanometers, but we need to filter in the 250-450 nm range. What would be ideal would be a laminated glass with uv interlayer. Any ideas? |

Tinted or Clear? What about Low-E coating? Try Viracon and maybe Schott |

I have an interest in restoring old books and this site may come in handy if you are concerned about conservation of items and protection from UV. there is a list of sources at the end of the article, including 3M www.nedcc.org/plam3/tleaf24.htm |

According to GANA and other publications that I have read, visible light is also a major contributor to fading, not just UV in the range below 380 nm. Some work by ISO is trying to develop a damage-weighted methodology to assess fading potential. According to an article in Glass Magazine in September of 2005, low-e and tinted glass can be as effective in preventing fading as laminated, when considering the damage-weighted fading potential. (The article was written by Per Werthwein of AFG Industries in Toronto.) Lawrence Berkely Lab's WINDOW software--which is used to model thermal performance, including SHGC, by most manufacturers--reportedly can calculate this effect for glass combinations. Some manufacturers have new products that claim to prevent more fading than laminated glass. Guardian Industries produces a product called ClimaGuard SPF. While they have some data on this on their web site (www.climaguardspf.com), there are no comparisons to laminated presented. They have authored an article in the same issue of Glass Magazine. Perhaps contacting the author, Tim Singel at Guardian, would yield greater information, and they may be willing to produce a couple of comparative models using the LBL WINDOW software. According to the article, his phone number in Auburn Hills, MI is 734-654-4243, email is tsingel@guardian.com. |
