Standard float glass

So called because it is manufactured using the Pilkington float system, whereby molten glass is floated on top of molten tin to create a perfectly uniform flat finish. Typically we use 2mm float glass, however for frames larger than a metre in width, 3mm float should be used as it is less likely to flex and break, however there will be increased weight.

Conservation Clear glass (UV filtering)

This glass is optically coated to protect artwork from the damaging effects of ultra violet light such as colour fading and paper deterioration which is irreversible. Conservation clear glass has a UV filter coating on one side filtering out approximately 98% of UV rays, compared to standard float glass which offers around 60% protection. Visually conservation clear glass looks identical to standard float glass.

Reflection control glass

This type of glass is designed to allow a wide viewing angle under harsh lighting conditions. It is especially suitable for artwork that has large flat areas of dark colour, which under standard float glass would have a mirror effect. There are two types of reflection control glass:
Etched anti reflect (AR) glass
This glass is acid etched on one side which diffuses the reflected light and gives a matte finish. It can be used over double mounts with minimal loss of contrast, although if the artwork is further away from the glass than this, there will be a noticeable softening of the artwork, therefore it is not suitable for box framing.
Coated anti reflect (AR) glass
This is a water white glass coated with the same metallic oxides used on binoculars and camera lenses, giving optimum clarity and zero colour shift to the artwork. It dramatically reduces surface reflections to <1% with light transmission over 98%. This can be used in box frames.
The term water white refers to float glass that has very low levels of the metallic impurities that give standard float glass its slight green tinge.

Museum glass

This is a coated anti reflect water white glass (as above) with the addition of 98% UV filtration. It has excellent clarity, high light transmission and zero colour shift. Quite simply it is the clearest picture glass available.

Cast acrylic

3mm Plexiglass (ultra clear acrylic) is useful for framing items where safety is an issue for instance in hotels or public places. There is also a weight advantage when framing larger items. The downside is that acrylic scratches more easily than glass, and is also prone to static build up which makes it unsuitable for glazing pastel or chalk artwork.
It is available with an anti reflect optical coating (AR) and/or with 98% UV filtration.

Mirror glass

monkeymirror_700x671We can supply mirror glass, either plain or antique (with an aged effect applied) which may be bespoke framed in most mouldings.
