Visually pleasing but with no long term protection, it's better than minimum and better than ready made framing. There is no  protection from physical and mechanical damage, airborne pollution and acid damage.

Guild Commended Level framing should visually enhance the artwork and will give a moderate level of protection from physical and mechanical damage, airborne pollution and acid damage. A window mount or slip should normally be used to visually enhance the artwork and distance it from the glazing.

Guild Conservation Level framing gives a high level of protection for your artwork or objects, whilst looking good and enabling you to view your framed work to best effect. By using conservation quality materials and the best techniques, this level can give your work protection from physical and mechanical damage, airborne pollution and acids generated by many framing materials.

Museum Level Framing is not confined to museums' works. Some artwork gains museum-quality status over time. Works that are to be preserved for future generations, including high value items and artwork of potential or historical value should be framed to Museum Level, where possible. Processes are intended to be fully reversible up to 35 years, which means that the framed work can be returned to its' former state, i.e. prior to framing, at any time, assuming that the artwork is not inherently unstable.
