Swallow Heron 8x8 ThermoWood Lean To Greenhouse and Installation

Write the first review


It's not difficult to see why this Heron 8ft x 8ft Wide Lean To greenhouse is so popular. Useful if you're a hobby gardener, it will also be an attractive addition to your property.  

Built by British craftsmen in traditional style, all Swallow greenhouses now use heat treated ThermoWood® which has invaluable qualities to ensure that the lean to has a very long and useful life.    

With moisture and resin excluded, the timber is extremely hardwearing and will not contract or expand. This means there is terrific resistance against warping and rot, with no preservatives required.

The lean to has many standard features, roof vents are fitted with automatic openers, there's silicone sealed toughened glazing which is compulsory if the lean to is over an entrance, and a 20mm damp barrier.

Full length staging occupies one side and can be extended into an 'L' shape. Entry into the lean to is easy through double doors that have a mortice lock for security.  

This is a greenhouse that is built to last, a pleasure to be inside, with delivery and installation included in the price.
