We use float glass to meet most of our framing needs, where the subject contains large dark areas, non-reflective glass should be considered. In addition to these glasses there are speciality-glazing products available for filtering Ultra Violet, Reflection Control and Image enhancing. These products are expensive, but if you have invested in artwork, you need to protect that investment. For museum framing, UV glass must be used. We only supply glass as part of the frame.

Ultra Violet Filtration

Ultra violet can be very damaging to artwork, for example, watercolours. It can cause fading and discolouration over a period of time, damage that is irreversible. Valuable pictures should never be hung in direct sunlight and wherever possible the light levels should be kept to a minimum, the lighter the room in which the picture hangs, the faster the deterioration. Daylight is the most damaging, with fluorescent lighting also emitting a high amount of light in the UV range, tungsten lighting in comparison emits around 4% of its light in the UV range. Filtration glass screens out more than 90% of the harmful rays, which will slow the damaging effect and which when used in conjunction with careful lighting, will provide the most stable environment for the artwork. This type of glass is available in clear and reflection control. Museum glass has a low reflectance optical coating plus a UV filter, this glass has good light transmission properties allowing the artwork to be viewed in lower light levels.

Reflection Control

One side of this glass is very finely etched; it is ideal for controlling reflection in harsh lighting conditions.

Image Enhancing

Perfect Vue is a finely etched glass with a low reflectance coating; Denglass Waterwhite has a low reflectance optical coating and low-iron glass substrate resulting in zero colour shift. Waterwhite float is the same as Denglas but without the optical coating. All the above offer good light transmission.
