THIS ALTON EVOLUTION OCTAGONAL GREENHOUSE: Alton greenhouses have been a traditional favourite with UK gardeners for many years. In 2018 this wonderful range was thoroughly reviewed and modernised. The result is stronger and longer lasting greenhouses with a more sophisticated dry glazing system, improved door performance and more controllable ventilation. At the same time the natural beauty of the high grade cedar has been improved with thicker and stronger framing with less bracing and a modern colourless finish. Behind the striking new look most of the popular old features have been retained including toughened safety glass as standard, no overlapping glass and low threshold doors. Some of the old features have been significantly enhanced especially the gutters, the staging and the shelving. The result is an even better range of greenhouses which evolved from the old market leader, hence the new models are known as the Alton Evolution.

HYBRID ALUMINIUM AND CEDAR CONSTRUCTION: This modern hybrid greenhouse combines the warmth and beauty of cedar with the rigidity and durability of extruded aluminium. Intelligent use of aluminium protects the timber and prolong its life. The base plinth and the door threshold are aluminium which ensures no direct contact between any timber and the ground. Almost all of the cedar framing is enclosed and internal which ensures lasting strength and good looks. The aluminium components are powder coated in a shade of grey which compliments the cedar when new and as it fades.

HEAVY DUTY CEDAR FRAME: The cedar frame features substantial timber which requires no additional bracing. The design combines traditional joinery features such as morticed and tenoned joints with modern production techniques to ensure great strength and fast installation. All cedar is treated with a colourless preservative which provides a waterproof seal without hiding the beautiful natural colour of the cedar. Rounded edges enhance the soft natural feel of the wood.

DURABLE ALUMINIUM COMPONENTS: Most of the aluminium components are used in the parts of the greenhouse which are the wettest. This includes the base, the door threshold and the gutters. The aluminium components are powder coated in a shade of grey which has been chosen to complement the appearance of cedar when it is new but also as it fades to a silvery grey colour.

WESTERN RED CEDAR: Western Red Cedar is a naturally resilient timber which lasts longer than pine and other softwoods, even if never treated from new. It has been widely used in construction for over a century. During this time cedar has deservedly earned an unrivalled reputation for its attractive appearance and extraordinary durability. It is the ideal choice for people who are too busy to maintain their garden building. This oily timber has a strong but pleasant aroma which repells insects. Cedar contains hardly any knots. If untreated it will fade to a silvery grey colour. Western Red Cedar is a sustainable resource from the well managed forests of North America.

POWDER COATED ALUMINIUM: The powder coated finish is more attractive than the stark silver finish aluminium greenhouses. The tough finish also has excellent weathering properties and retains its gloss and colour superbly. A good example of powder coating is the finish on your washing machine. Powder coated aluminium greenhouses have a similar finish.

TOUGHENED GLASS: Toughened glass is the best glazing material for use in greenhouses. It is around 6 times stronger than normal glass so it is less likely to break and when it does break toughened glass breaks into harmless small pieces. This makes toughened glass the best option for all the family including children, pets and the elderly. Toughened glass also strengthens the frame and it is heavy which helps to resist wind. Full height toughened glass is supplied in larger sizes than horticultural glass with no overlapping glass.

CEDAR PANELLING: The integral cedar panelling is tongued and grooved cedar matchboarding. Cedar panelling offers better heat retention in the winter than fully glazed greenhouses. It is also ideal for growing shade-loving plants such as ferns. The cedar cladding boards are fully built into the greenhouse frame as an integral part which cannot be detached.

BASE PLINTH: The base plinth makes installation much easier. It is designed to be a portable and prefabricated foundation beam. The plinth features a flat underside to spread the weight of the greenhouse over a larger area. The base plinth can be placed on any flat and level surface including soil, gravel, decking, concrete or paving slabs. It is best to prepare a perimeter footing of concrete or paving slabs for the base plinth to stand on. However, with care the base plinth can be placed on any surface including soil or gravel provided that the ground is flat and level.

GREENHOUSE LOCATION: Ideally your greenhouse should have a clear space at least 18" wide on all sides, if possible. This ensures easy access for both installation and future maintenance. In reality this is often not practical and at many sites it is not needed. A reduced clearance is often possible on one or two sides. You should cut back or remove any nearby shrubs and trees. Remember to allow for future growth. Ideally the ridge of a greenhouse should run from east to west. The best position for a freestanding greenhouse is a sunny spot outside the shadow of nearby buildings and trees. A sheltered position is best otherwise additional screening may be advisable. Plants need plenty of water so your greenhouse should be close to a water supply and the site should be well drained.

OCTAGONAL BUILDING SIZES: For ease of reference these octagonal greenhouses are measured as a rectangle. The first dimension listed is the overall width from side to side and the second dimension is the depth from front to back. The external wall sizes are listed alongside the price. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger.
