Since 1921, Alton Greenhouses have been at the forefront of the cedar greenhouse market. The iconic Amateur design with its sloping sides has lead the greenhouse market from the 1950's and was seen as the cutting edge of greenhouse design. With vast pools of knowledge, experience and years of customer feedback Alton’s design team have created a cedar greenhouse fit for the 21st century - this is the Alton Evolution Range.
The Alton Evolution is crafted within the UK, where each piece of cedar is machined in-house using Alton’s fully equipped workshop using CNC technology to create highly accurate results. This technology has enabled Alton to produce a flat - packed greenhouse that’s cost effective and easy to install. With a 5'7" eaves height, the Evolution is a spacious greenhouse and every care has been taken to ensure that the Canadian western red cedar is smooth and rounded at its edges - creating a luxurious high quality finish showing Alton's true craftsmanship. From the metal base plinth specially designed to keep the wood away from the floor which lets the glass overlap the wooden frame so no water sits on the cedar wood, the new glazing system, low threshold access, even through to the gutter design - the Alton Evolution really is revolutionary in the world of greenhouses.
Over the years greenhouses made from both aluminium and cedar have become thinner to save costs, after studying the process from raw material through to delivery the team at Alton discovered that a large part of the costs came from double handling, storage and distribution costs. After streamlining this process Alton have been able to add much thicker glazing bars based on 44 x 44 timbers or 44 x 69 in places giving you a truly robust greenhouse.
•A new optional bar capping system
Normally a wooden greenhouse will have its glass held in place with a beading or groove cut in to the wood, the result of this can lead to the glass rattling in the frame. The Alton Evolution new bar capping system uses the toughened glass as part of the greenhouse's overall strength by gripping the glass tightly preventing the rattling glass and giving a far stronger frame. This fantastic system means you can have a virtually maintenance-free cedar greenhouse and the stylish moss colour blends perfectly with the cedar's distinctive silvery colour.
•Mortice and tenon joints
These cleverly designed joints not only create strength throughout the Evolution's framework but also make the greenhouse really simple to install.
•Toughened safety glass
Being 5 -7 times stronger than horticultural glass the 3mm toughened safety glass, that is fitted as standard, means that every pane is helping to keep the greenhouse structure rigid.
•Optional aluminium staging and shelving
Unusual in a cedar greenhouse the aluminium staging and shelving in the moss green paint finish looks amazing. Unlike timber staging and shelving this will not stain or mark and can be easily wiped clean.
Alton Evolution 8ft 7in x 16ft 9in
This 8'7in ( 5.13m) wide model is just superb !
There's a choice of lengths from 6'6 ( 1.97m ) up to 12'9( 3.87m ), then you can add 8ft extension units so there's really no limit to how big you can make it !
Toughened safety glass and screw-in cedar bar capping are standard which ensures the glass stays where it's put ! The gutter, door support and base are long life aluminium construction which are then powder coated in an attractive moss green finish.
The double door has a low level threshold which means there's easy access for wheelchairs and pushchairs ( the staging can be set lower down for wheelchair users ).
The framework is rock solid with its sturdy mortice and tenon construction and it carries a ten year timber guarantee.
The Evolution Eight can be fitted with a partition to separate the growing area: handy if you want to heat part of the greenhouse to a different temperature, perhaps for bringing seedlings along in the spring.
The cantilever staging brackets are clearly shown in this picture which illustrates that there's plenty of unobstructed space for storage beneath the staging too.
Please take a look at the detail pictures on the other sizes of the Evolution as they illustrate many of the features and options available with the Evolution Eight.
The Alton Evolution Guttering is an attractive moss green finish aluminium extrusion and is supplied with a downpipe for each side of the greenhouse.
The external capping over the glazing is showing the optional green aluminium bar capping which is totally maintenance free ( except for a bit of a wash down every now and again ).
In particular please note how the toughened safety glass extends beyond the cedar eaves bar, discharging water directly into the gutters rather than allowing it to run across the cedar itself.
The Evolution has been developed in the UK in our fully equipped workshop with the latest technology. We have to confess though that one or two of the machines have been reliably making other Alton Greenhouses for over 40 years !
The jointing system is incredibly strong and makes the Evolution rock solid once assembled... so it will cope with almost anything the British weather cares to throw at it !
Constructed in long -life cedar sections these greenhouses do not compromise by using thinner glazing bars; they are machined from 44mm x 44mm cedar (and 44mm x 69mm sections in places )
Aluminium is rot proof, maintenance free, rigid and easily assembled ... that's just 4 reasons why it makes an ideal greenhouse base.
Normally you won't find it used as a base on cedar greenhouses because it doesn't match up with the rest of the building.
The Evolution is a special case ; because the components in the areas where the weather or watering takes its toll ( the eaves, base, staging, shelving, door support track ) are all constructed in aluminium, then powder coated for life with an attractive moss green colour, the base doesn't look out of place. Add to that the convenience of setting the greenhouse up in the first place ( rather than trying to lay out concrete blocks for instance ) and you'll see why this is so popular.
A single door is standard with the Evolution Five and Six. The Eight, Ten and Twelve have double doors. All sizes have the low threshold shown in the picture.
This makes it easy to wheel a barrow in and out or provide access for wheelchairs and pushchairs.
The single door access width is 560mm ( 22" )
The wider Evolution models have eaves and ridge braces in the following quantities :
Evolution Eight : 4 eaves braces and 2 ridge braces on the 10 & 12 ft long. 8ft extension also has the same: 4 & 2
Evolution Ten and Twelve : Eaves and ridge braces on every bar (and thicker roof bars). From this you will realise that the photo is one of these ! Please note the quality of the jointing from the picture.
Also in the picture are two roof blinds. You can see the black cartridges that the blinds unwind from so they are neat and easy to retract when not required.
The picture also illustrates that each roof vent is supplied with an automatic opener. Without these you can get to your greenhouse even early in the morning and find your plants keeling over from the heat. The autovent is a wax filled cylinder which forces a piston to lift the vent as the cylinder heats. They are adjustable and therefore a very effective way of maintaining an appropriate temperature inside your greenhouse.
