Cedar and the Alton 10 Year Guarantee
Alton Greenhouses are made from best grade Western Red Cedar (Thuja Plicata) that is Guaranteed for 10 Years whether or not you apply a timber treatment
This is possible because cedar is saturated in a natural preserving oil that not only gives the timber a distinctive odour and resistance to moths, insects and vermin but also it's famed resistance to decay and extraordinary durability
The greenhouses are dip treated at the factory in a 'Golden Honey' preservative which combines with the natural colour variation of the white cedar sapwood and dark reddish brown of the cedar heartwood to produce shades of natural colour
As it weathers, the colour of the wood changes to silver - similar to hardwood garden furniture - but if you prefer to keep the original colour or change it you can apply a timber stain
Cedar is very stable which means that it will not shrink or warp excessively when exposed to the British weather and so will continue to look good in your garden for many years
All the cedar used in Alton Greenhouses comes from FSC/PEFC/CSA certified sources
Alton is a Marshalls plc Specialist Company

What Size Greenhouse
Always buy the biggest greenhouse that space and budget will alllow - you can always fill them up!
If room in the garden is limited and you have a convenient garage or house wall, consider a lean-to style greenhouse (check the height though as they are relatively high)

Positioning your Greenhouse
The best location is normally as near as possible to your house without falling into it's shadow
Avoid siting your greenhouse near trees, in the shadow of buildings, walls etc. or in extremely exposed positions
Ideally you should site a freestanding greenhouse with it's ridge running from west to east as this gives better light penetration to the south side in the winter when the sun is low in the sky
Do consider other things such as water or electricity supply if you plan to heat the greenhouse
A lean-to greenhouse should ideally be sited against a south facing wall

Greenhouse Ventilation
Good ventilation is critical in a greenhouse in order to promote healthy growth and to avoid diseases such as 'grey mould'
Just opening the door is insufficient as you need to create a good circulation of fresh, mild air to exhaust the hot air and so we recommend that you include ample air bricks in your base construction
Dwarf wall greenhouses are supplied with a number of roof vents and side louvre vents as standard but you can always add more if required and fit optional automatic openers
