The Alton Evolution 10’8″greenhouse
The Evolution Ten is a serious greenhouse for a serious Gardener. With the modular system, you can extend to any length that you want to and you can even add internal partitions with double doors to create separate environments within the greenhouse. (Plus; a partition adds considerable strength as well.)
The Cedar frame is based on 44×44 timbers and in the roof we use the extra thick 69×44 making the frame really solid. The first thing that you will notice when you walk in is the wonderful Cedar aroma. It’s this pleasant smell that deters some insects and pests from the greenhouse and of course the Cedar gives a cosy warm home for your plants.
The Alton Evolution Ten comes complete with Metal base plinth, Stainless steel screws, Aluminium Guttering, low level door threshold, Automatic roof vents, louvre side vents, high eaves and toughened glass.
The glass is held in with Cedar bar capping as standard, and you can upgrade this to the optional Aluminium system for a more maintenance free greenhouse. Western red cedar
We select only the best Western Red Cedar, supplied from renewable sources as it’s the ideal material for use in our greenhouses. Noted for its extraordinary durability, it doesn’t shrink, swell or warp excessively, and readily holds wood stains and micro-porous paints. It has prime insulating qualities and its pleasant aroma is naturally repellent to moths, insects and vermin.
finest-materialsAll of our unpainted greenhouses are factory-treated by total immersion in our Golden Honey cedar preservative prior to delivery which renders it virtually immune to decay, while our painted greenhouse options look stylish in any outdoor setting and are protected with micro porous paint.
If you wish to maintain the original warm, golden honey colour, we recommend you re-treat your frame annually. If not, the wood will gradually fade to its attractive natural appearance – varying from almost pure white of the narrow sapwood to the light straw shade of the heartwood. This will not affect your 10 year framework guarantee.
Other features and options
Mortice and tenon joints.The Cleverly designed jointing system on the Evolution has the duel benefit of making assembly straight forward and adding strength to the framework.
Aluminium base – This keeps the wood well away from the base where water can sit. Plus this unique design feature allows the glass to sit directly onto the metal base – which means that the side water is not running onto the wood, (which is a ‘rot-spot’ on other greenhouses) The Metal base is included on every Evolution model, regardless of which kind of capping you choose.
gutters and downpipes
Guttering Takes the water away and allows you to collect it. Included on every model regardless of which kind of capping you choose.
Roof vents. A generous allocation of roof vents is included with every model and every roof vent has an automatic opener included as standard. These clever devices work through heat expansion alone to open your roof vents gradually as the temperature changes. Fully adjustable, they help you to create the perfect growing environment.
Louvres Your new Alton Evolution model will also include one or more louvre windows. These work in tandem with your roof vents – as the automatic roof vents open and release the warm air, the greenhouse effectively sucks air in through the louvres. These can be positioned near the bottom or the top and on most models at the side of the greenhouse or at the rear. Supplied as manual opening as standard and you can add automatic louvre openers if you wish.
The unique Alton Evolution door system includes the low-profile door threshold. This popular feature means that you have no step at the door (many other greenhouses have a step at the door). Models of 8′ wide and above have 4′ wide access double doors which allow easy entrance for a wheelbarrow or wheelchair.
Aluminium bar capping
Upgrade option Aluminium bar capping – With this new Aluminium bar capping system you really can have a virtually maintenance free Cedar greenhouse – and the stylish moss colour blends in perfectly with the cedar as it ages to the distinctive silvery colour.
The eaves height of 5’7″ on the Alton Evolution models is excellent and is as much as 18″ higher than the lowest greenhouses on the market. The extra height gives you several advantages: There is more air in the greenhouse creating a better growing environment, you have more head room and a higher door, and you have plenty of room for a high level shelf in the greenhouse.
* The Ultimate Package includes an upgrade to aluminium bar capping from the standard cedar capping, aluminium shelving and staging in moss green to length, down one side.
