Alton Greenhouses are made from the finest Western Red Cedar.
Every model in our extensive range is attractively designed,
solidly built in their factory in the heart of England and available
with a wide range of options and accessories to personalise
DO I HAVE TO KEEP PAINTING MY CEDAR
Its a common myth that if you choose a Cedar greenhouse then
you will spend the rest of your life painting it! In fact the
natural oils contained within Cedar are far better than any
man-made preservative. Alton do factory dip the greenhouses,
so they come with a coat of oilbased preservative, however it
is cedar's natural oils which will actually keep it going for
so long. Therefore there is actually no technical need to treat
your greenhouse again. In time, it will fade to an attractive
silvery-grey colour. You could re-treat it every few years if
you wanted to top-up the original colour and ensure an even
longer life. In fact it is far more important to actually clean
it once a year and remove algae than to treat it. Your Alton
greenhouse is guaranteed for 10 years even if you never retreat
it, and it may well last 20 years without treatment.
Alton greenhouses are made from strong Cedar profiles
and fitted with numerous braces for good wind strength.
The roof braces are made from brown powder coated aluminum which
is finished with an attractive scrolled end - ideal for hanging
On longer models with extensions,extra A-frame braces are provided.
The concrete base kerbs are one of the most famous
features of an Alton greenhouse. These are factory moulded and
provide very sturdy anchorage for your greenhouse. You'll need
a firm foundation of either a simple concrete footing or, if
you prefer, a fully slabbed base. The kerbs help with wind strength
and are supplied in a natural finish - but you can paint them
with a masonry style paint if you so wish.
All Alton greenhouses come with 3mm
toughened safety glass as standard. Toughened glass is 5-7 times
stronger than horticultural glass and if it does break it disintegrates
into small pieces - reducing the chance of injury. Most Alton
greenhouses are delivered in a series of factory glazed panels
- which means less handling of glass and a speedier assembly.
Glass is held in by either special rebates in the cedar frame
or with cedar full length beading. Again, this is good for wind
strength and gives a finish which is aesthetically pleasing.
Almost all the glazing is in large sheets with no overlaps,
and neat pvc strips join panes where required on the gable ends.
ALTON UNIQUE 'VENTACCESS' SLIDING
Only available on Alton greenhouses,
these superb sliding side vents are a real advantage. It’s well
known that ventilation is vital in a greenhouse and that most
greenhouses do not have enough vents as standard. It's also
important that you have a combination of roof vents (to release
hot air) and low-level vents (to draw in cool fresh air). Each
Amateur and Traditional model has a generous allocation of roughly
1 VentAccess every other panel (so an 8x10 model for example
has four VentAccess and two roof vents). The VentAccess can
be opened from the outside of the greenhouse which is ideal
when your beds are full of tomatoes, or when staging is in the
way on the inside.
Louvres are an option on most models and are normally situated
at a mid height. You can also fit auto-louvre openers to these
for automatic opening.
Each model comes with a certain number of roof vents
and extra roof vents can sometimes be added. We recommend that
you also add some auto-vent openers which will automatically
open the roof vent as the greenhouse warms up.
The height of the eaves is vital on a greenhouse
as this gives you more head-room, more room for tall plants
to grow and more room for a high level shelf. All Alton greenhouse
have at least 5'5" to the eaves.
EASY SLIDE DOORS
Many Alton greenhouses come with an easy-slide
door with no threshold or step at the door. The kerbless doorways
provide good access for wheelbarrows and you can even lock the
door by fitting a padlock (not supplied).
On the Amateur and Traditional models, you
can add the clip-on cedar panels. Once you have initially fitted
all the brackets, these clip on panels can be added quickly
and easily to one or more side or end of the greenhouse. They
are ideal for creating a more traditional boarded bottom appearance,
they create a little extra insulation in winter and they can
hide potentially messy storage areas under the staging.
WHY TWO DIFFERENT
The Amateur models with sloping sides create more light transmission
through the sides, particularly in the winter months when the
sun is low. Amateurs are also slightly sturdier due to the sloping
side design. The straight sided Traditional model allows you
more room at the top for shelving as you don't 'lose' any space.
The choice is yours!
Standard now on all models - even octagonals.
Alton guttering is slightly smaller than 'house' guttering and
is therefore nicely in proportion with the greenhouse. Guttering
is vital for keeping rain off the sides and collecting the vital
resource in a waterbutt.
Alton staging & shelving is made from a special
finger jointed hardwood on redwood bearers. The high level shelves
are an ideal feature which add highly practical extra capacity.
Staging is available in a choice of widths to suit your greenhouse.
The unique powder coated steel brackets give strong support
and are brown colour coded to give a more attractive finish.
The 8ft and 10ft wide Amateur models can be
fitted with internal partitions with hinged doors. This will
create a separate environment at the back of the greenhouse
- ideal for propagating or overwintering to reduce heating bills.
