Swallow Falcon 13x31 ThermoWood Greenhouse with Installation

Write the first review


The Falcon 13ft x 31ft greenhouse is a magnificent structure, one of Swallow's largest traditionally styled greenhouses

It benefits greatly from the use of ThermoWood®, timber that has been heat treated to remove moisture and resin. It therefore doesn't contract or expand, and this stability is vital to avoid the frame warping. The wood is also very resistant to rot, hence no preservatives are required. 

Extremely resilient, the greenhouse will withstand bad weather and it is only Swallow who use this marvellous material for their greenhouses.

You'll find many other great features and options, staging for example is fitted as standard along one side. Toughened glazing is silicone sealed and there are no less than 10 air vents each with an automatic opener. Options include a rainwater collection system and extra shelving.

A greenhouse of this size naturally demands double doors, and these open inwards to aid your entry if pushing a wheelbarrow or carrying large garden equipment.

With so much working and growing space, both at the sides and centrally, this will be a very productive greenhouse, and great value when you consider that delivery and installation are included in the price.
