ALTON GREENHOUSES

A whole concept for a Cedar Greenhouse...

Since 1921, Alton has been at the forefront of the Cedar greenhouse market. The iconic sloping sided Amateur greenhouse has led the market for decades and at the time of its introduction in the 50s it was at the cutting edge of greenhouse design.

Since then, the Alton design team have been pooling their vast knowledge and experience, along with years of feedback from our customers in order to create a Cedar greenhouse fit for the 21st Century. Designed and manufactured in the UK Your Alton model is crafted in our own workshop in Staffordshire.

Every piece of Cedar is machined in-house in their fully equipped workshop. Some of these machines have been reliably making Alton greenhouses for over 40 years. Other, more modern additions use CNC technology to give highly accurate results.

Advances in machining and joinery technology have enabled for the first time a flatpacked greenhouse which actually takes no longer to assemble than the old system of awkward to handle fully glazed panels.

COLD FRAMES

Flexible lid system (hinged, sliding and removable) gives you many different ventilation options.

Bar capping options

The Evolution cold frame comes as a choice of two models – one with cedar capping to retain the glass and one with Aluminium capping.

If you want to retain the natural timber look of your cold frame then you can stick with the cedar capping, however if you want to go for more maintenance free, then you can choose the Aluminium capping system.

Powder coated in the Moss colour, this is designed to blend in perfectly with the cedar both when new and later when the cedar weathers to its natural silvery colour. If you intend to add the Cedar panel upgrade kit, then you will need to use the cedar capping kit.

Optional boarding kit

You can also add the cedar panelling kit for your cold frame, this consists of a full set of boards for all around the cold frame, all made from quality western red cedar.

They can give a cosier area for the plants as the wood insulates, as well as having an attractive appearance.They will, of course, reduce light to your plants.

Luckily, when you add a boarding kit, it is fully flexible.You can just put some of the boards in and leave some sections with just glass in or you can remove the boards and just have all glass.

The way that this works in practice is that the capping holds the glass in and also holds the boards in in a similar way (so to change to boards you need to remove the glass and insert the boards) which is done fairly easily by simply unscrewing the capping and swapping over.
