Picture Framing Glass

Whether you want to protect your treasured artwork behind glass is one of the most important decisions you will have to make after selecting a frame.

No matter what kind of art you have there are certain advantages to displaying it behind glass. They include keeping fingers off the surface of a picture. Even the briefest touch can leave harmful residue on an image.

Modern glass can protect an artwork from the ravages of ultra-violet rays. This invisible part of the spectrum of sunlight, causes works on paper or works made up of other organic material to deteriorate over time.

One of the greatest modern inventions in framing has been the creation of glass with minimal glare. This means that when you use glass to protect a work of art it will have only minimal effect on the appearance. It will simply disappear when seen from most angles in your home.

FAQ about Glass and Glazing:

When should I use acrylic?
It is recommended to using acrylic for hanging and shipping heavy oversized artwork, in children’s rooms, in earthquake zones, in high traffic areas or anywhere where safety is a concern.

Does acrylic have out-gassing?
No framing grades of acrylic have out-gassing.  However, to be certain, we recommend only buying acrylic made in North America.  All our acrylic products are out-gassing free.

When should I use a thicker acrylic product?
You should use 3mm acrylic when the frame’s size exceeds 36”x48”.  Optium Museum Acrylic for oversized framing projects over 40”x60”.

How much space should I allow for expansion and contraction?
The standard 1/16” is recommended for every 12".

What type of glazing should I use for pastel or charcoal based art?
Pastel or charcoal based art can become damaged using most glazing products due to the inherent static charge of the substrate.  Tru Vue Optium® Acrylic Glazing provides long-lasting anti-static as well as anti-reflective properties to help protect art from damage and to help showcase your art the way it was intended.

How does anti-reflective glass reduce reflection?
The thin film coatings on Tru Vue anti-reflective glass disrupt the energy contained in light waves causing them to flow out of sync. This disrupted wave pattern virtually eliminates all reflection from the glass surface. Diagrams of how this process works are included with the descriptions of all anti-reflective products.

What is non-glare glass?
Non-glare picture framing glass is finished to diffuse reflected light. This process also gives the glass surface a matte finish.

How do I clean Tru Vue glass products?
All of Tru Vue glass products are clean and ready to use out of the box.  If spot cleaning is needed, spray a small amount of ammonia-free glass cleaner on a micro-fiber cloth or a clean lint-free cotton rag.  To prevent overspray, do not spray the cleaner directly on the glass.  Press the cloth against the glass and clean in a round, circular motions.

Why does Tru Vue recommend using an ammonia-free glass cleaner?
Cleaning glass products with harsh chemicals such as ammonia can be harmful to your customers’ valued pieces.  Ammonia can cause out-gassing within the framing package.

How can I remove the inkjet printing from the lite of glass?
The inkjet printing is printed at the very edge of the lite of glass and is small enough to be hidden by the rabbet of the frame.  If you choose to remove the inkjet printing, apply a small amount of acetone (fingernail polish remover) to a cotton swap to wipe the lite clean.
