Polycarbonate greenhouse


A high quality Redpath Polycarbonate twinwall greenhouses with a 10 Year manufacturers frame warranty.
6mm thickness polycarbonate is used for the roof, sides, ends, door(s) and roof vent(s).  The louvre vent window uses Polycarbonate sheets as this provides greater strength in windy conditions for the tilting window.

There are three widths of the polycarbonate greenhouse models to choose from.  The “Urban’PC” model 2.56m length and 3.2m length is designed with space efficiency in mind with its 1.92m width allowing it to be placed in a more compact garden area. 
The wider “Statesman’PC” model at 2.56m wide allows for increased central walkway space or a wider growing space to each side of the walkway.
‘The Beast PC’ model is 3.2m wide and 6.3m long, for the large hobby famer or lifestyle block holder – a new design for 2021
Many standard features are built into these greenhouse models (see the specifications below) and there is a wide selection of accessories also available such as aluminium shelves, extra roof vents, extra louvre windows, double doors or doors at both ends, automatic opening roof vents, free standing staging shelf units, shadecloth support clips and crop support hanger rings etc.

Frame is in aluminium silver finish, and is the same robust and proven structure as our glass clad glasshouses. We no longer offer a powder coating option out of respect to helping the environment, – but your local powder coating service provider will likely be able to offer this option.
This Urban and Statesman models have the option of swapping out the 6mm polycarbonate for ultra-long life glass for the roof or all surfaces at a later date if you desire.
For summertime there is an optional “Throw-over” shadecloth for effective summertime cooling.  Ropes and tie down saddles are included.

The greenhouse base dimensions are shown in the link HERE it’s important to get the base dimensions right when you set up your greenhouse base; – the material used for the base might be treated timber, cement, blocks or bricks. A comprehensive set of instructions and assembly drawings are supplied with every kitset.
