Swallow Raven Greenhouse 8x20

The Swallow range of wooden greenhouses are made from Thermowood, which is manufactured from quality redwood pine. The process involves kiln drying the timber which is then put in a special oven, where a powerful compressor removes the air. The temperature is raised to 215°C, which bakes the timber.This natural, chemical free process seals the capillaries, destroys resins and proteins, and stabilises the timber.The benefits are that it can be left untreated as all bacteria is killed, resulting in an improved durability against decay. It also gives a consistent colour throughout the wood and paints really well – the finish lasting up to three times longer than it would otherwise.The frame is also protected by a strong plastic ‘U’ section damp barrier.

The Swallow Kingfisher Combi comes with 3mm toughened glass. Toughened safety glass is much more robust than horticultural glass. This means that the panes are really strong and much more able to withstand accidental damage.In the event of a breakage, a pane of toughened glass will break safely into many small pieces, rather than producing the hazardous shards that you get with the standard horticultural glass.

This greenhouse comes with eight roof vents and automatic roof vent openers as standard, for convenience and automatically controlled ventilation.  

The double inward opening doors give great access for barrows and wheelchairs, and have a mortice lock and key for added security.

Every Swallow greenhouse that leaves the factory is made with care and attention to detail, and backed by a 12 year guarantee against rot and decay and 3 years against fixtures and fittings – so you know that you are buying a product that can be enjoyed for years to come.
