The low down on glazing…
An item that can divide opinion in framing is glazing. I decided early on that I didn’t want to use acrylic in frames I make and would use cut glass. Unless I can find a recycled or recyclable option, but at the time of publication I’m only using glass unless absolutely necessary (its generally not).
When it comes to choosing glass for your picture frames, I think the simplest way to think about it is by splitting it into three categories:
Standard Float
It may be the cheapest option but float glass makes a perfectly acceptable choice if UV protection is not a major concern and you don’t mind some reflection.
UV Protection
If your artwork is of value and is displayed in a room that has any sunlight, then choosing a high percentage of UV protection will slow fading or deterioration. Note the word slow - constant exposure to direct sunlight can cause minor effects even behind the most protective glazing product
Anti-Reflective
If you want to reduce or eliminate reflections or reduce glare in harsh lighting conditions, then a percentage of anti-reflective properties will provide improved clarity.
There are various percentages of protection to choose from and also glass that combines both anti-reflective + UV protection. The more protection, the higher the cost so speak to your framer who will be able to advise you on what is absolutely necessary
