Steve, Can I have contact details for Glass & Mirror please? A google UK search did not identify them. Thanks, John T -----Original Message----- From: DigitalBlackandWhiteThePrint@yahoogroups.com [mailto:DigitalBlackandWhiteThePrint@yahoogroups.com] On Behalf Of Steve Kale Sent: 01 April 2006 11:43 To: DigitalBlackandWhiteThePrint@yahoogroups.com Subject: [Digital BW] Interesting comment re UV filtering I was chatting with a UK glass supplier yesterday about glazing for some prints. He made a comment that I thought was interesting with respect to UV filtering. Ordinary glass will apparently filter approximately 40-45% of UV light. So in a modern house/building with double-glazed windows more than 64% of the outside UV light doesn't even make it indoors - even in an interior with many windows. (He actually said 80%, ie 2 x 40%, but I assume the relevant maths is multiplicative rather than additive.) He rated the UV filtering of Denglass Water White, for example, at 40%. Schott Miroguard Plus he rated at 84%. (Apparently Denglass is a Schott product made under license.) In the context of interior exhibited prints we chatted about what was more important, UV filtering or the clarity and light transmission of the print glazing. He was very much in favour of the latter - poor quality glazing (even if UV) can dull (by blocking too much light) and colour shift prints. For UK listeners, Glass & Mirror will supply cut-to-size WW Denglass at £75/m2+Vat and Schott Miroguard Plus at £99/m2+Vat. For a 16x20 print with a good border that's roughly £38 and £50, respectively. Not cheap but the very best materials and a lot cheaper than what a frame shop will charge - likely only half as much. I find it much cheaper to do my own framing, sourcing pre-cut mats and boards from the US (a bit cheaper than I can buy uncut boards here), chop to size moulding from Ashworth & Thompson, and, if desired, glazing from the above. Assembly is easy with some basic equipment. The above works out considerably cheaper and uses better materials than a frame shop in London.
