Swallow Heron 8 x 18 ft ThermoWood Lean To Greenhouse

There's no doubting that the Heron 18ft x 8ft wide Lean To greenhouse will prove particularly attractive to serious gardeners as it offers a massive opportunity to grow and impressive range of plants.   

This is a very productive and traditionally styled structure that benefits from the outstanding qualities of ThermoWood®. Heat treatment has stabilised the wood and, with moisture and resin removed, it will not suffer from rot or warp. 

The timber's lifespan is therefore expanded and there is no need for preservatives. It's worth remembering that only Swallow manufacture greenhouses using this marvellous material.

Inside the greenhouse you'll find fantastic growing conditions. Four roof vents encourage an effective flow of fresh air, essential to avoid overheating. Staging along one side comes as standard, more can be optioned if required as well as a high shelf.

Toughened glass allows in lots of light while access is straightforward, even if you have a wheelbarrow or large equipment, through double doors that are fitted with a mortice lock.

All gardeners will recognise this lean to as a superb structure with the added value of delivery and installation included in the price.
