Swallow Raven 8 x 12 ft ThermoWood Greenhouse

The Raven 12ft x 8ft Greenhouse is built in the UK by craftsmen at Swallow. Double doors make entry into the greenhouse very easy, even if you are pushing a wheelbarrow.

Mixing traditional design with modern construction methods unique to their range of greenhouses, Swallow use ThermoWood® to build the frame. This is timber that has been heat-treated to eliminate almost all moisture and resin. As a result, shrinkage and expansion are minimal, as is warping and rot. In fact, preservatives need not be applied.

The exterior of the greenhouse is very durable, inside the growing environment is ideal for a wide range of plants. No less than four roof vents introduce a fresh flow of air, and staging is fitted along one side.

Light flows through the toughened glass and the glazing is sealed with high-quality silicone. There is a 20mm damp course and in addition, you have the choice of various optional extras, for example, a rainwater collection kit to aid recycling.

A Combination Shed is also a great option, adding working space and also a storage area.
