Duplex Terrarium - Enclosure Plans

Description

Our "Duplex" terrarium measures 196cm x 70x 70 cm (outside dimensions) and has a removable separating wall. The weight (without glass and without inside décor) is about 18kg.
The polycarbonate sheets are stuck together with aluminum profiles, they are very stable, easy to clean, lightweight and very durable. The connections are sealed with silicone.
Our “branches” are made of white PVC pipes of various widths, scorched with a blow torch. (Attention: TOXIC fumes: only do this outside with eye protection, gloves and a good mask!)
The center wall is removed in this picture but can be added at any time.

We heat with 2 “Pro Heat” heat panels @65 Watts controlled by a Herpstat PRO proportional thermostat.
All of the cables (2x thermostat, 2x thermometer and 2x hygrometer are hidden inside the PVC branches)
Lighting: 2 florescent fixtures with 21 Watt full-spectrum tubes.

OK now for the detailed "building instructions":
Disclaimer:
The following instructions have been put together to the best of our knowledge, but we take no responsibility for problems or damages that may result from someone following them.
I will begin with a list of the materials (I’m not sure where these can be purchased in the USA, so you’ll have to check the internet.)
The sizes are given in cm/mm because it’s much more exact than inches and that’s how we did ours.

4 x Multi-wall Polycarbonate sheets (the material used to build greenhouses, etc)
Color: Super Cool White
16mm thick 200 x 98cm
What is special about the diamond polycarbonate sheets is their special hollow inner structure which improves the insulation and stability.

I'm not sure where or if you can get these in the US: The place I ordered mine will ship to the USA and Canada: M&S Reptilien

You just have to know how thick your glass pieces are in millimeters. They have 6mm wide and 4mm wide tracks. PS -- The English translation is not brilliant: they say "up" and "down" when they mean "top" and bottom": You need to order a top track and a bottom track or the glass will not fit into place

16x Ventilation hole covers: round 50mm
