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.
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.
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.
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.
Evo Eight
This Alton Evolution Eight model has the advantage over its smaller cousins of having an extra wide (4ft) double door. This gives you good access to the greenhouse if you are carrying bulky items, and thanks to the Evolution’s low level threshold, good access with a wheelbarrow as well.
The metal base keeps cedar away from the damp floor and the overlapping roof sheets ensure that water runs straight in to the aluminium guttering so that you can collect the fresh water for your plants.
Did you also know that all Evolution models are actually factory treated in a clear spirit based wood preservative? This means that the Cedar wood is far less prone to staining than other Cedar greenhouses on the market which are delivered untreated.
This Alton Evolution Eight greenhouse will come with Cedar bar capping as standard, but if you prefer to go for virtually maintenance free then you can upgrade to the Aluminium bar capping. These full length Aluminium capping strips actually screw into the wooden frame and grip the toughened safety glass securely into the Cedar frame. The powder coated Moss colour complements the Cedar– even more so as it ages to a nice silvery mature colour.
As with all Alton Evolution models, this model comes with a generous level of ventilation including automatic roof vents and louvre side vents.
