Glass vs acrylic glazing - which is best?
Helping you to decide on the right glazing for your artwork or photograph.
When it comes to selecting either glass and acrylic (plexiglass) for your frame, it can be confusing as to which one is best for your needs. Whether you are looking for a lightweight, shatterproof option or a traditional look, we hope you will find all the information you need to make the right choice.
Glazing is an important aspect of framing that often a little overlooked. Glass and Acrylic’s are the two primary materials to consider, both of which we offer in our bespoke made frames. In the past only ever used glass for all our framing (standard 2mm / non reflective / conservation or museum glass). Increasingly we are now using Acrylic Glass for a number of reasons which we have listed below. But in particularly you cant tell it is an acrylic, it is also a greener option and it is more transparent with no tint (unlike some glass).
Glass
Standard glass
The standard glass type, to a picture framer, is normally a 2mm clear float glass, we occasional use 3mm and 4mm for larger pictures. It is relatively inexpensive and will protect your artwork from dust and physical damage.
Pros –
Inexpensive
Reliable, it will not degrade and could last for hundreds of years
Is easy to clean
It is fully recyclable
Cons –
Very reflective
No UV protection.
Slight green colour cast and less transparent than acrylic.
Very fragile making it difficult and expensive to ship without damage.
If it breaks it can cause damage to the work and frame, or in the worse case cause injury
Glass is vulnerable to condensation as its a good insulator, creating a risk of moisture which could damge your artwork

The Art / Museum quality glass is exceptional. The non-reflective coating does minimise glare and stops 90% plus of UV light from hitting your image, prolonging the image from fading.
Pros -

It is a tad expensive, but well worth the investment.

Acrylic
As a business we have started to use Acrylic more and more, at our clients requests.
Initially we were a little concerned it would look like plastic and not give the high end look we were after. But we have been pleasantly surprised at the quality (unlike glass it’s perfectly clear) and the visual experience it gives. It has been extremely popular with our commercial clients as the risk of injury (its both lightweight and shatter resistance), especially in areas of high footfall.
Standard (2mm) Acrylic Glass
Acrylic Glass allows 92% light transmission, more than that of float glass which tends to be 90% or lower. Acrylic Glass, unlike 2mm float glass is also tint free and visually colourless and has 66% inherent UV resistance due to the UV stabilizer that is added to protect against ageing. This absorbs many of the damaging UV wavelengths in natural and artificial light.
Pros –
Inexpensive
Reliable, it will not degrade and could last for hundreds of years
Excellent clarity, 92% transmission showing the true colours
Tint free, virtually colourless unlike Float glass and Styrene
Shatter resistant and safe
Lightweight
Safe for shipping to clients
Safe for commercial / high traffic areas
It is fully recyclable
Cons –
Reflective
It can scratch when cleaning, care should be taken
Slightly dearer than 2mm float glass
