ThermoWood® is a modern construction material that is used only in Swallow greenhouses. Its fantastic qualities are put to good use when you consider an 8ft x 18ft Raven Greenhouse.
This is an attractive traditionally styled structure that is highly warp and rot resistant because the timber has been heat treated to remove moisture and resin it, therefore, doesn't expand or shrink and no preservatives are required.
Double doors mean getting into the greenhouse is easy even with large garden equipment or a wheelbarrow. Once inside you'll realise that this is a very productive growing area with six roof vents that automatically open and light flowing through the toughened glass that has been silicone sealed.
Staging is already in place along one side to assist sowing seed and potting, and you can choose to have a high shelf as well. Other options include a rainwater collection system for recycling and a Combination Shed that would offer storage and your working space.
