Perspex is expensive. Why not go for polycarbonate. One of the sides lets in UV. I use it for my outdoor vivs.

Graham or anyone else, have you tried using this perspex? I see its available in 2, 3 and 5mm thicknesses and was wondering if the thickness affects UV transmission?

Hi Peter and others, The thiner the thickness of the Acrylic the more U.V it allows through, I had the spec for this years ago but I have misplaced it.

Hi, I can't comment on how the thickness affects UV but I contacted Custom Acrylics & Woods regarding price etc and they were very helpful.

I use 2mm UV transmitting acrylic in my greenhouse (aka sunbed grade acrylic) and it lets through around 85-90% natural UV. Other thicknesses are available but seem to let less UV through (as expected) plus are more expensive. Normal acrylic and polycarbonate from Wickes, BandQ etc have no UV transmission at all- ive tried them with a UV meter. The medium ive found that lets UV through is the expensive UV transmitting acrylic- if you are offered it cheaply then it probably isnt UV transmitting (price for a 2m x 3m x 2mm thick piece is now around £150). Interestingly ive also found that cricket tubs also let UV through- useful for raising baby day geckos etc in (under a UV tube indoors).

Hi Rob,
You mentioned that you use the perspex in your greenhouses ? I was informed by the company that the perspex isn't appropriate for outside use ? If yours is outside how is it fairing up ? I used "normal" perspex on top of my cages during winter and the cold weather a few years ago and eventually it degraded and became scratched opaque and brittle. I didn't want to waste that amount of money for something that would only last for a short time. Incidentally, it would be interesting to find out what material the cricket tubs are made from and if it is available commercially !!

Please see the last link on my links page at www.sauria.org.uk/links.htm. I have been using the UV transmitting acrylic supplied by them for several years with no degradation or loss of transmission. Chris

Hi, came across this website whilst pondering options for covered vivaria, maybe this "new" polythene could be just what we are looking for (looked at other polytunnel suppliers and most seemed to offer "full spectrum" transmission products, this was just first one I came across) also quite interesting stuff on "insect vision" and UV. www.robinsonpolytunnels.co.uk/acatalog/Polythene.htmlS
